Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) from interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. Changes to GAAP are established by the Financial Accounting Standards Board (“FASB”) in the form of Accounting Standards Updates (“ASU’’) to the FASB’s Accounting Standards Codification (“ASC”). In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation of the results of operations for the periods presented have been included. Operating results for the nine months ended September 30, 2016 and 2015, are not necessarily indicative of the results that may be expected for the fiscal year. The balance sheet at December 31, 2015, has been derived from the audited consolidated financial statements at that date, but does not include all of the information and footnotes required by GAAP for complete financial statements. You should read these condensed consolidated financial statements together with the historical consolidated financial statements of the Company for the year ended December 31, 2015, included in the Company's Annual Report on Form 10-K for the year ended December 31, 2015, filed with the SEC on February 29, 2016.

Significant Accounting Policies	Sep. 30, 2016
Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies Please see Note 2 to the Company's Consolidated Financial Statements included in the Company’s Form 10-K for the fiscal year ended December 31, 2015, for a description of all significant accounting policies. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. Accounts Receivable Accounts receivable represent amounts due from customers for which revenue has been recognized. Generally, the Company does not require collateral or any other security to support its receivables. The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses in the Company’s existing receivables. The Company determines the allowance based on factors such as historical collection experience, customers' current creditworthiness, customer concentrations, age of accounts receivable balance and general economic conditions that may affect the customers' ability to pay. Inventories Inventory is valued at the lower of cost or market value. The Company assesses the valuation of its inventory on a periodic basis and makes adjustments to the value for estimated excess and obsolete inventory based on estimates about future demand. The excess balance determined by this analysis becomes the basis for the Company's excess inventory charge. The Company's excess inventory review process includes analysis of sales forecasts, managing product rollovers and working with operations to maximize recovery of excess inventory. The value of inventory as of September 30, 2016 includes a fair value step - up connected with the January 2016 acquisition of Stability Inc. of approximately $600,000, which is comprised of approximately $2.1 million as of the date of the acquisition less amortization of approximately $1.5 million during the nine months ended September 30, 2016. Please see Note 4 contained herein. Revenue Recognition The Company sells its products through a combination of a direct sales force and independent stocking distributors and representatives in the U.S. and independent distributors in international markets. The Company recognizes revenue when title to the goods transfers to customers, provided there are no material remaining performance obligations required of the Company or any matters of customer acceptance. In cases where the Company utilizes distributors or ships product directly to the end user, it recognizes revenue upon shipment provided all other revenue recognition criteria have been met. A portion of the Company's revenue is generated from inventory maintained at hospitals, clinics and doctor's offices. For these products, revenue is recognized at the time the product has been used or implanted. The Company records estimated sales returns, discounts and allowances as a reduction of net sales in the same period revenue is recognized. Acquisitions Results of operations of acquired companies are included in the Company’s results of operations as of the respective acquisition dates. The purchase price of each acquisition is allocated to the net assets acquired based on estimates of their fair values at the date of the acquisition. Any purchase price in excess of these net assets is recorded as goodwill. The allocation of purchase price in certain cases may be subject to revision based on the final determination of fair values during the measurement period, which may be up to one year from the acquisition date. Contingent consideration is recognized at the estimated fair value on the acquisition date. Subsequent changes to the fair value of contingent payments are recognized in earnings. Contingent payments related to acquisitions consist of an earn out based on sales less direct production costs, and are valued using discounted cash flow techniques. The fair value of these payments is based upon probability-weighted future revenue estimates and increases or decreases as revenue estimates or expectation of timing of payments changes. Patent Costs The Company incurs certain legal and related costs in connection with patent applications for tissue-based products and processes. The Company capitalizes such costs to be amortized over the expected life of the patent to the extent that an economic benefit is anticipated from the resulting patent or alternative future use is available to the Company and are included in Intangible Assets in the Condensed Consolidated Balance Sheets. The Company capitalized approximately $515,000 of patent costs during the first nine months of 2016. The Company capitalized approximately $594,000 of patent costs during the first nine months of 2015. Treasury Stock The Company accounts for the purchase of treasury stock under the cost method. Treasury stock which is reissued for the exercise of option grants and the issuance of restricted stock grants is accounted for on a first - in first - out (FIFO) basis. Recent Accounting Pronouncements The Company considers the applicability and impact of all Accounting Standards Updates ("ASUs") issued, both effective and not yet effective. In May 2014, the FASB issued ASU 2014-09, “Revenue Recognition - Revenue from Contracts with Customers” (ASU 2014-09) that requires companies to recognize revenue when a customer obtains control rather than when companies have transferred substantially all risks and rewards of a good or service. This update is effective for annual reporting periods beginning on or after December 15, 2017 and interim periods therein and requires expanded disclosures. The Company is currently assessing the impact the adoption of ASU 2014-09 will have on our condensed consolidated financial statements. In November 2015, the FASB issued ASU No. 2015-17, "Balance Sheet Classification of Deferred Taxes". ASU 2015-17 simplifies the presentation of deferred taxes by requiring deferred tax assets and liabilities be classified as noncurrent on the balance sheet. ASU 2015-17 is effective for public companies for annual reporting periods beginning after December 15, 2016, and interim periods within those fiscal years. The guidance may be adopted prospectively or retrospectively and early adoption is permitted. The Company adopted this standard, prospectively, at the beginning of the fourth quarter 2015 to simplify reporting with the release of the valuation allowance as disclosed in Note 12. Prior periods were not retrospectively adjusted. In February 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)". The core principle of Topic 842 is that a lessee should recognize the assets and liabilities that arise from both capital and operating leases. ASU 2016-02 is effective for public companies for annual reporting periods beginning after December 15, 2018, and interim periods within those fiscal years. The guidance may be adopted prospectively or retrospectively and early adoption is permitted. The Company is currently assessing the impact the adoption of ASU 2016-02 will have on its consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-09, "Compensation - Stock Compensation (Topic 718)". The standard is intended to simplify several areas of accounting for share - based compensation arrangements, including the income tax impact, classification on the statement of cash flows and forfeitures. This ASU is effective for fiscal years beginning after December 15, 2016. The Company is currently assessing the impact the adoption of ASU 2016-09 will have on its consolidated financial statements. In August 2016, the FASB issued ASU No. 2016-15, “Statement of Cash Flows (Topic 230) Classification of Certain Cash Receipts and Cash Payments”. The update addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. This ASU is effective for public business entities for fiscal years beginning after December 15, 2017 and for interim periods within those fiscal years. The amendments in this update may be applied retrospectively or prospectively and early adoption is permitted. The Company is currently assessing the impact of the adoption of ASU 2016-15 will have on its consolidated financial statements. All other ASUs issued and not yet effective for the nine months ended September 30, 2016, and through the date of this report, were assessed and determined to be either not applicable or are expected to have minimal impact on the Company's financial position or results of operations.

Acquisition of Stability Inc.

Business Combinations [Abstract]

Acquisition of Stability Inc.

On January 13, 2016, the Company completed the acquisition of Stability Inc., d/b/a Stability Biologics ("Stability"), a provider of human tissue products to surgeons, facilities, and distributors serving the surgical, spine, and orthopedic sectors of the healthcare

industry. As a result of this transaction, the Company acquired all of the outstanding shares of Stability in exchange for

$6,000,000 cash, $3,346,000 in stock, represented by 441,009 shares of our common stock, and assumed debt of $1,771,000. Additional one time costs incurred in connection with the transaction totaled $1,088,000 and are included within selling, general and administrative expenses on the condensed consolidated statements of operations. Contingent consideration may be payable in a formula determined by sales less certain expenses for the years 2016 and 2017. As of September 30, 2016, the contingent consideration was valued at $25,620,000 and is shown in the schedule below as fair value of earn-out. The Company used a third party specialist to assist us with the valuation. The contingent consideration was classified as a liability.

The Company has evaluated the contingent consideration for accounting purposes under GAAP and has determined that the

contingent consideration is within the scope of ASC 480 "Distinguishing Liabilities from Equity" whereby a financial instrument,

other than an outstanding share, that embodies a conditional obligation that the issuer may settle by issuing a variable number

of its equity shares shall be classified as a liability if, at inception, the monetary value of the obligation is based solely or

predominantly on variations in something other than the fair value of the issuer’s equity shares.

The actual purchase price was based on cash paid, the fair value of our stock on the date of the acquisition, and direct costs

associated with the combination. The actual purchase price has been preliminarily allocated as of September 30, 2016 (in

thousands) and is subject to change:



Cash paid at closing	$	6,000
Working capital adjustment	(480		)
Common stock issued (441,009 shares valued at $9.07 per share)	3,346
Assumed debt	1,771
Fair value of earn-out	25,620
Total fair value of purchase price	$	36,257

Net assets acquired:
Debt-free working capital	$	2,179
Other assets, net	199
Property, plant and equipment	1,375
Deferred tax liability	(8,268		)

Trade names and trademarks	830
Non compete agreements	1,080
Licenses and permits	690
Subtotal	17,860
Goodwill	22,912
Total Assets Purchased	$	36,257

Working capital and other assets were composed of the following (in thousands):
Working capital
Cash	$	140
Prepaid Expenses and other current assets	100
Accounts receivable	2,001
Federal and state taxes receivable	28
Inventory	8,725
Accounts payable and accrued expenses	(8,815		)
Debt-free working capital	$	2,179

Current portion of long term debt	$	(194	)
Long-term debt	(560		)
Line of Credit	(932		)
Shareholder loan	(85		)
Net working capital	$	408

Other assets:
Other long term assets	$	199

The acquisition was accounted for as a purchase business combination as defined by FASB Topic 805 - "Business Combinations". The fair value of the contingent consideration is measured as a Level 3 instrument. The contingent consideration liability is recorded at fair value on the acquisition date and will be remeasured quarterly until purchase accounting is completed based on the assessed fair value and adjusted if necessary. The increases or decreases in the fair value of contingent consideration can result from changes in anticipated revenue levels and changes in assumed discount periods and rates. As the fair value measured is based on significant inputs that are not observable in the market, they are categorized as Level 3. The income valuation approach was applied in determining the fair value of the contingent consideration using a discounted cash flow valuation technique with significant unobservable inputs comprised of projected sales and certain expenses. The values assigned to intangible assets are subject to amortization. The intangible assets were assigned the following lives for amortization purposes:



		Estimated useful life (in years)
Intangible asset:
Customer relationships		12
Patents and know-how		20
Trade name and Trademarks		Indefinite
Non compete agreements		4
Licenses and permits		2

Goodwill consists of the excess of the purchase price paid over the identifiable net assets and liabilities acquired at fair value.

Goodwill was determined using the residual method based on an independent appraisal of the assets and liabilities acquired in

the transaction and is preliminary as of September 30, 2016 and is subject to change. Goodwill is tested for impairment on an annual basis as defined by FASB Topic 350 - "Intangibles - Goodwill and Other".

The following unaudited pro forma summary financial information presents the consolidated results of operations for the Company as if the acquisition had occurred on January 1, 2015. The pro forma results are shown for illustrative purposes only and do not purport to be indicative of the results that would have been reported if the acquisition had occurred on the date indicated or indicative of the results that may occur in the future.

Unaudited pro forma information for the three and nine months ended September 30, 2016 and 2015 (in thousands) is as follows:



	Three months ended September 30,				Nine Months Ended September 30,
	2016		2015		2016		2015
Revenue	$	64,429	$	52,108	$	175,687	$	148,521

Net income	$	3,406	$	4,253	$	7,074	$	12,227

Income per share, fully diluted	$	0.03	$	0.04	$	0.06	$	0.11

The 2016 supplemental pro forma earnings were adjusted to exclude $1,088,000 of acquisition-related legal, audit and other

costs, net of tax. The 2015 supplemental pro forma earnings were adjusted to include $1,186,000 of amortization costs related to recorded intangible assets with defined useful lives, and $1,471,000 of inventory step-up charges as a result of the acquisition for comparability to 2016. The number of shares outstanding used in calculating the income per share for 2015 was adjusted to include 441,009 shares issued as part of the purchase price and assumed to be issued on January 1, 2015.

- Definition

The entire disclosure for a business combination (or series of individually immaterial business combinations) completed during the period, including background, timing, and recognized assets and liabilities. The disclosure may include leverage buyout transactions (as applicable).

Amended and Restated Assumed 2005 Stock Plan (the “Assumed 2005 Plan”). The awards are subject to a vesting schedule as set forth in each individual agreement. The Company currently intends to use only the 2016 Plan to make future grants.

Activity with respect to the stock options is summarized as follows:

Total unrecognized compensation expense related to granted stock options at September 30, 2016, was approximately $2,150,652 and will be charged to expense ratably through May 2017.

The fair value of options granted by the Company is estimated on the date of grant using the Black-Scholes-Merton option-pricing model that uses assumptions for expected volatility, expected dividends, expected term, and the risk-free interest rate. Expected volatilities are based on historical volatility of peer companies and other factors estimated over the expected term of the options. The term of employee options granted is derived using the “simplified method,” which computes expected term as the mid point between the weighted average time to vesting and the contractual maturity. The simplified method was used due to the Company's lack of sufficient historical data to provide a reasonable basis upon which to estimate the expected term due to the limited period of time its equity shares have been publicly traded. The term for non-employee options is generally based upon the contractual term of the option. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant for the period of the expected term or contractual term as described.

The assumptions used in calculating the fair value of options using the Black-Scholes-Merton option-pricing model are set forth in the following table:



	Nine Months Ended September 30,
	2016	2015
Expected volatility	n/a	54.4 - 58.1 %
Expected life (in years)	n/a	6.0
Expected dividend yield	n/a	—
Risk-free interest rate	n/a	1.51 - 1.68%

There were no options granted during the nine months ended September 30, 2016.

Restricted Stock Awards

Activity with respect to restricted stock awards for the nine months ended September 30, 2016 is summarized as follows:



	Number of Shares		Weighted-Average Grant Date Fair Value
Unvested at January 1, 2016	2,613,267		$9.14
Granted	2,369,876		7.98
Vested	(952,910	)	8.75
Forfeited	(137,575	)	8.73
Unvested at September 30, 2016	3,892,658		$8.54

As of September 30, 2016, there was approximately $23,767,731 of total unrecognized stock-based compensation related to time-based, nonvested restricted stock. That expense is expected to be recognized on a straight-line basis over a weighted-average period of 2.0 years, which approximates the remaining vesting period of these grants. All shares noted above as unvested are considered issued and outstanding at September 30, 2016.

For the three and nine months ended September 30, 2016 and 2015, the Company recognized stock-based compensation as follows (in thousands):

Income Tax Disclosure [Abstract]
Income taxes	Income taxes The effective tax rates for continuing operations of 31.5% and 3.2% for the nine months ended September 30, 2016 and September 30, 2015, respectively, were determined using an estimated annual effective tax rate and include, in 2016, the impact of discrete items of approximately $900,000. The effective tax rate for the 2016 period increased approximately 28.3% when compared to the same period of 2015, primarily due to the $15.4 million valuation allowance release recorded in 2015 and discussed in our Annual Report on Form 10-K for the year ended December 31, 2015. Due to the valuation allowance previously recorded against the Company's U.S. deferred tax assets, the effective tax rate for the nine months ended September 30, 2015, did not include the expense of the current period U.S. taxable income. As of the end of September 2016, the projected annual effective tax rate for 2016 is approximately 41.0%.

FDA Untitled Letter and Draft Guidance

On August 28, 2013, the FDA issued an Untitled Letter alleging that the Company's micronized allografts do not meet the criteria for regulation solely under Section 361 of the Public Health Service Act and that, as a result, MiMedx would need a biologics license to lawfully market those micronized products. Since the issuance of the Untitled Letter, the Company has been in discussions with the FDA to communicate its disagreement with the FDA's assertion that the Company's allografts are more than minimally manipulated. To date, the FDA has not changed its position that the Company's micronized products are not eligible for marketing solely under Section 361 of the Public Health Service Act, but discussions are continuing. The Company continues to market its micronized products but is also pursuing the Biologics License Application (“BLA”) process for certain of its micronized products.

On December 22, 2014, the FDA issued for comment “Draft Guidance for Industry and FDA Staff: Minimal Manipulation of Human Cells, Tissues, and Cellular and Tissue-Based Products.” Essentially the Minimal Manipulation draft guidance takes the same position with respect to micronized amniotic tissue that the FDA took in the Untitled Letter to MiMedx 16 months earlier. The Company submitted comments asserting that the Minimal Manipulation draft guidance represents agency action that goes far beyond the FDA’s statutory authority, is inconsistent with existing HCT/P regulations and the FDA’s prior positions, and is internally inconsistent and scientifically unsound. On October 28, 2015, the FDA issued for comment, "Draft Guidance for Industry and FDA Staff: Homologous Use of Human Cells, Tissues, and Cellular and Tissue-Based Products." The Company submitted comments on this Homologous Use draft guidance as well. On September 12 and 13, 2016, the FDA held a public hearing to obtain input on the Homologous Use draft guidance and the previously released Minimal Manipulation draft guidance, as well as other recently issued guidance documents on HCT/Ps. The Company awaits further decision from FDA on the draft guidances, but anticipates this will be a lengthy process.

If the FDA does allow the Company to continue to market a micronized form of its sheet allografts without a biologics license either prior to or after finalization of the draft guidance documents, it may impose conditions, such as labeling restrictions and compliance with Current Good Manufacturing Practices (cGMP). Although the Company is preparing for these requirements in connection with its pursuit of a BLA for certain of its micronized products, earlier compliance with these conditions requires significant additional time and cost investments by the Company. It is also possible that the FDA will not allow the Company to market any form of a micronized product without a biologics license even prior to finalization of the draft guidance documents and could even require the Company to recall its micronized products. Revenues from micronized products comprised approximately 12% of the Company's revenues for the fiscal year ended December 31, 2015.

Patent Litigation

MiMedx continues to diligently enforce its intellectual property against several entities. Currently, there are four actions pending, as described below:

The Liventa Action

On April 22, 2014, the Company filed a patent infringement lawsuit in the United States District Court for the Northern District of Georgia against Liventa Bioscience, Inc. ("Liventa"), Medline Industries, Inc. ("Medline") and Musculoskeletal Transplant Foundation, Inc. ("MTF") for permanent injunctive relief and unspecified damages (the "Liventa Action"). In addition to the allegations of infringement of MiMedx's patents, the lawsuit asserts that Liventa and Medline knowingly and willfully made false and misleading representations about their respective products to providers, patients, and in some cases, prospective investors. Though the terms of the agreement are confidential, the parties have reached an amicable settlement of the false advertising claims for an undisclosed sum. The patent infringement claims are still pending as described below.

MiMedx asserts that Liventa (formerly known as AFCell Medical, Inc.), Medline and MTF infringed and continue to infringe certain of the Company's patents relating to the MiMedx dehydrated human amnion/chorion membrane ("dHACM") allografts. MTF is the tissue processor while Liventa and Medline are the distributors of the allegedly infringing products. On May 30, 2014, defendants filed answers to the Complaint, denying the allegations in the Complaint. They also raised affirmative defenses of non-infringement, invalidity, laches and estoppel. MTF and Medline also filed counterclaims seeking declaratory judgments of non-infringement and invalidity. Defendants filed parallel Inter Partes Review ("IPR") proceedings which are discussed below. We expect the case to go to trial in 2017.

The Bone Bank Action

On May 16, 2014, the Company also filed a patent infringement lawsuit against Transplant Technology, Inc. d/b/a Bone Bank Allografts ("Bone Bank") and Texas Human Biologics, Ltd. ("Biologics") for permanent injunctive relief and unspecified damages (the "Bone Bank Action"). The Bone Bank Action was filed in the United States District Court for the Western District of Texas. This lawsuit similarly asserts that Bone Bank and Biologics infringed certain of the Company's patents through the manufacturing and sale of their placental-derived tissue graft products. On July 10, 2014, Defendants filed an answer to the Complaint, denying the allegations in the Complaint. They also raised affirmative defenses of non-infringement and invalidity and filed counterclaims seeking declaratory judgments of non-infringement and invalidity. Defendants also filed parallel IPR proceedings which are further discussed below. Discovery is closed and we expect the case to go to trial in the early part of 2017.

The NuTech Action

On March 2, 2015, the Company filed a patent infringement lawsuit against NuTech Medical, Inc. ("NuTech") and DCI Donor Services, Inc. ("DCI") for permanent injunctive relief and unspecified damages. This lawsuit was filed in the United States District Court for the Northern District of Alabama. The lawsuit alleges that NuTech and DCI have infringed and continue to infringe the Company's patents through the manufacture, use, sale, and/or offering of their tissue graft product. The lawsuit also asserts that NuTech knowingly and willfully made false and misleading representations about its products to customers and/or prospective customers. The case is currently in the discovery phase.

The Vivex Action

On April 1, 2016, the Company also filed a patent infringement lawsuit against Vivex BioMedical (“Vivex”) for permanent injunctive relief and unspecified damages (the "Vivex Action"). The lawsuit was filed in the United States District Court for the Northern District of Georgia. The patent at issue is the 8,709,494 patent (the "494" patent). Vivex answered MiMedx’s Complaint and filed Counterclaims of noninfringement and invalidity.

Pending IPRs

In addition to defending the claims in the pending district court litigations, defendants in the Liventa and Bone Bank cases have challenged certain of the Company's patents in several IPR proceedings to avoid the high burden of proof of proving invalidity by "clear and convincing evidence" in the district court litigations. An inter partes review (or "IPR") is a request for a specialized group within the United States Patent and Trademark Office to review the validity of a plaintiff's patent claims. The defendants in the Bone Bank Action challenged the validity of the Company's 8,597,687 (the "687" patent) and the 494 patent; while the defendants in the Liventa Action challenged the validity of the Company's 8,372,437 and 8,323,701 patents (the "'437" and "'701" patents, respectively).

On June 29, 2015, the Patent Trial and Appeals Board ("PTAB") denied the Bone Bank defendants' request for institution of an IPR with respect to the '494 patent (EpiFix) on all seven challenged grounds. On August 18, 2015, the PTAB also denied the Liventa defendants' request for institution of an IPR with respect to the '701 patent (AmnioFix) on all six challenged grounds. That is, the PTAB decided in each case that the defendants failed to establish a reasonable likelihood that defendants would prevail in showing any of the challenged claims of the '494 or the '701 patent were unpatentable.

On July 10, 2015, the PTAB issued an opinion allowing a review of the '687 patent to proceed, although on only two of the five challenged grounds. The parties decided to forego oral arguments. On July 7, 2016, the PTAB issued an opinion finding that the challenged claims, which relate to embossment and not configuration, were invalid for obviousness. On August 18, 2015, the PTAB issued an opinion allowing a review of the '437 patent to proceed, although only on one of the seven challenged grounds. On August 16, 2016, the PTAB issued an opinion finding that the challenged claims were unpatentable. MiMedx has filed a notice of appeal of the PTAB’s decision regarding the '437 patent.

Significant Accounting Policies (Policies)	9 Months Ended
Significant Accounting Policies (Policies)	Sep. 30, 2016
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) from interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. Changes to GAAP are established by the Financial Accounting Standards Board (“FASB”) in the form of Accounting Standards Updates (“ASU’’) to the FASB’s Accounting Standards Codification (“ASC”). In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation of the results of operations for the periods presented have been included. Operating results for the nine months ended September 30, 2016 and 2015, are not necessarily indicative of the results that may be expected for the fiscal year. The balance sheet at December 31, 2015, has been derived from the audited consolidated financial statements at that date, but does not include all of the information and footnotes required by GAAP for complete financial statements. You should read these condensed consolidated financial statements together with the historical consolidated financial statements of the Company for the year ended December 31, 2015, included in the Company's Annual Report on Form 10-K for the year ended December 31, 2015, filed with the SEC on February 29, 2016.
Segment Reporting	The Company operates in one business segment, Regenerative Biomaterials, which includes the design, manufacture, and marketing of products and tissue processing services for the Wound Care, Surgical, Sports Medicine, Ophthalmic and Dental market categories.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.
Accounts Receivable	Accounts Receivable Accounts receivable represent amounts due from customers for which revenue has been recognized. Generally, the Company does not require collateral or any other security to support its receivables. The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses in the Company’s existing receivables. The Company determines the allowance based on factors such as historical collection experience, customers' current creditworthiness, customer concentrations, age of accounts receivable balance and general economic conditions that may affect the customers' ability to pay.
Inventories	Inventories Inventory is valued at the lower of cost or market value. The Company assesses the valuation of its inventory on a periodic basis and makes adjustments to the value for estimated excess and obsolete inventory based on estimates about future demand. The excess balance determined by this analysis becomes the basis for the Company's excess inventory charge. The Company's excess inventory review process includes analysis of sales forecasts, managing product rollovers and working with operations to maximize recovery of excess inventory.
Revenue Recognition	Revenue Recognition The Company sells its products through a combination of a direct sales force and independent stocking distributors and representatives in the U.S. and independent distributors in international markets. The Company recognizes revenue when title to the goods transfers to customers, provided there are no material remaining performance obligations required of the Company or any matters of customer acceptance. In cases where the Company utilizes distributors or ships product directly to the end user, it recognizes revenue upon shipment provided all other revenue recognition criteria have been met. A portion of the Company's revenue is generated from inventory maintained at hospitals, clinics and doctor's offices. For these products, revenue is recognized at the time the product has been used or implanted. The Company records estimated sales returns, discounts and allowances as a reduction of net sales in the same period revenue is recognized.
Acquisitions	Acquisitions Results of operations of acquired companies are included in the Company’s results of operations as of the respective acquisition dates. The purchase price of each acquisition is allocated to the net assets acquired based on estimates of their fair values at the date of the acquisition. Any purchase price in excess of these net assets is recorded as goodwill. The allocation of purchase price in certain cases may be subject to revision based on the final determination of fair values during the measurement period, which may be up to one year from the acquisition date. Contingent consideration is recognized at the estimated fair value on the acquisition date. Subsequent changes to the fair value of contingent payments are recognized in earnings. Contingent payments related to acquisitions consist of an earn out based on sales less direct production costs, and are valued using discounted cash flow techniques. The fair value of these payments is based upon probability-weighted future revenue estimates and increases or decreases as revenue estimates or expectation of timing of payments changes. The acquisition was accounted for as a purchase business combination as defined by FASB Topic 805 - "Business Combinations". The fair value of the contingent consideration is measured as a Level 3 instrument. The contingent consideration liability is recorded at fair value on the acquisition date and will be remeasured quarterly until purchase accounting is completed based on the assessed fair value and adjusted if necessary. The increases or decreases in the fair value of contingent consideration can result from changes in anticipated revenue levels and changes in assumed discount periods and rates. As the fair value measured is based on significant inputs that are not observable in the market, they are categorized as Level 3. The income valuation approach was applied in determining the fair value of the contingent consideration using a discounted cash flow valuation technique with significant unobservable inputs comprised of projected sales and certain expenses. The values assigned to intangible assets are subject to amortization.
Patent Costs	Patent Costs The Company incurs certain legal and related costs in connection with patent applications for tissue-based products and processes. The Company capitalizes such costs to be amortized over the expected life of the patent to the extent that an economic benefit is anticipated from the resulting patent or alternative future use is available to the Company and are included in Intangible Assets in the Condensed Consolidated Balance Sheets.
Treasury Stock	Treasury Stock The Company accounts for the purchase of treasury stock under the cost method. Treasury stock which is reissued for the exercise of option grants and the issuance of restricted stock grants is accounted for on a first - in first - out (FIFO) basis.
Recent Accounting Pronouncements	Recent Accounting Pronouncements The Company considers the applicability and impact of all Accounting Standards Updates ("ASUs") issued, both effective and not yet effective. In May 2014, the FASB issued ASU 2014-09, “Revenue Recognition - Revenue from Contracts with Customers” (ASU 2014-09) that requires companies to recognize revenue when a customer obtains control rather than when companies have transferred substantially all risks and rewards of a good or service. This update is effective for annual reporting periods beginning on or after December 15, 2017 and interim periods therein and requires expanded disclosures. The Company is currently assessing the impact the adoption of ASU 2014-09 will have on our condensed consolidated financial statements. In November 2015, the FASB issued ASU No. 2015-17, "Balance Sheet Classification of Deferred Taxes". ASU 2015-17 simplifies the presentation of deferred taxes by requiring deferred tax assets and liabilities be classified as noncurrent on the balance sheet. ASU 2015-17 is effective for public companies for annual reporting periods beginning after December 15, 2016, and interim periods within those fiscal years. The guidance may be adopted prospectively or retrospectively and early adoption is permitted. The Company adopted this standard, prospectively, at the beginning of the fourth quarter 2015 to simplify reporting with the release of the valuation allowance as disclosed in Note 12. Prior periods were not retrospectively adjusted. In February 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)". The core principle of Topic 842 is that a lessee should recognize the assets and liabilities that arise from both capital and operating leases. ASU 2016-02 is effective for public companies for annual reporting periods beginning after December 15, 2018, and interim periods within those fiscal years. The guidance may be adopted prospectively or retrospectively and early adoption is permitted. The Company is currently assessing the impact the adoption of ASU 2016-02 will have on its consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-09, "Compensation - Stock Compensation (Topic 718)". The standard is intended to simplify several areas of accounting for share - based compensation arrangements, including the income tax impact, classification on the statement of cash flows and forfeitures. This ASU is effective for fiscal years beginning after December 15, 2016. The Company is currently assessing the impact the adoption of ASU 2016-09 will have on its consolidated financial statements. In August 2016, the FASB issued ASU No. 2016-15, “Statement of Cash Flows (Topic 230) Classification of Certain Cash Receipts and Cash Payments”. The update addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. This ASU is effective for public business entities for fiscal years beginning after December 15, 2017 and for interim periods within those fiscal years. The amendments in this update may be applied retrospectively or prospectively and early adoption is permitted. The Company is currently assessing the impact of the adoption of ASU 2016-15 will have on its consolidated financial statements. All other ASUs issued and not yet effective for the nine months ended September 30, 2016, and through the date of this report, were assessed and determined to be either not applicable or are expected to have minimal impact on the Company's financial position or results of operations.
Net Income (Loss) Per Share	Net Income (Loss) Per Share Basic net income (loss) per common share is computed using the weighted-average number of common shares outstanding during the period. Diluted net income per common share is computed using the weighted-average number of common and dilutive common equivalent shares from stock options, restricted stock, and warrants using the treasury stock method.
