Nature of Operations [Policy Text Block] |
Navidea’s Manocept platform is predicated on the ability to specifically target the CD206 mannose receptor expressed on activated macrophages. The Manocept platform serves as the molecular backbone of Tc99m tilmanocept, the first product developed and commercialized by Navidea based on the platform.In July 2011, we established a European business unit, Navidea Biopharmaceuticals Limited, to address international development and commercialization needs for our technologies, including Tc99m tilmanocept. Navidea owns 100% of the outstanding shares of Navidea Biopharmaceuticals Limited.In January 2015, Macrophage Therapeutics, Inc. (“MT”) was formed specifically to explore immuno-therapeutic applications for the Manocept platform. Navidea owns 99.9% of the outstanding shares of MT.In March 2017, pursuant to an Asset Purchase Agreement, the Company completed the sale to Cardinal Health 414, LLC (“Cardinal Health 414” ) of its assets used, held for use, or intended to be used in operating its business of developing, manufacturing and commercializing the Company’s radioactive diagnostic agent marketed under the Lymphoseek® trademark in Canada, Mexico and the United States (the “Asset Sale”). Our consolidated balance sheets and statements of operations have been reclassified, as required, for all periods presented to reflect the Lymphoseek business sold to Cardinal Health 414 as a discontinued operation. Cash flows associated with the operation of this business have been combined with operating, investing and financing cash flows, as appropriate, in our consolidated statements of cash flows. Other than Tc99m tilmanocept, which the Company has a license to distribute outside of Canada, Mexico and the United States, none of the Company’s drug product candidates have been approved for sale in any market.On
April 26, 2019, the Company effected a one -for-twenty reverse stock split of its issued and outstanding shares of its common stock, par value $.001 per share (“Common Stock”). As a result of the reverse split, each twenty pre-split shares of Common Stock outstanding automatically combined into one new share of Common Stock. The number of outstanding shares of Common Stock was reduced from approximately 201.0 million to approximately 10.1 million shares. The authorized number of shares of Common Stock was not reduced and remains at 300.0 million. The par value of the Company’s Common Stock remained unchanged at $0.001 per share after the reverse split. Our consolidated balance sheets, statements of operations, statements of stockholders’ (deficit) equity, and accompanying notes to the financial statements have been restated, as required, for all periods presented to reflect the reverse stock split as if it had occurred on January 1, 2018. Our consolidated statements of cash flows were not impacted by the reverse stock split. |

Fair Value of Financial Instruments, Policy [Policy Text Block] |
Level – Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;1
Level – Quoted prices in markets that are 2
not active or financial instruments for which all significant inputs are observable, either directly or indirectly; andLevel – Prices or valuations that require inputs that are both significant to the fair value measurement and unobservable.3
A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. In determining the appropriate levels, we perform a detailed analysis of the assets and liabilities whose fair value is measured on a recurring basis. At each reporting period, all assets and liabilities for which the fair value measurement is based on significant unobservable inputs or instruments which trade infrequently and therefore have little or no price transparency are classified as Level 3. See Note 5.
The following methods and assumptions were used to estimate the fair value of each class of financial instruments:

Share-based Payment Arrangement [Policy Text Block] |
Stock options granted under the 2002 Plan and the 2014 Plan generally vest on an annual basis over one to four years. Outstanding stock options under the plans, if not exercised, generally expire ten years from their date of grant or up to 90 days following the date of an optionee’s separation from employment with the Company. We issue new shares of our Common Stock upon exercise of stock options.Stock-based payments to employees and directors, including grants of stock options and restricted stock, are recognized in the statements of operations based on their estimated fair values on the date of grant, subject to an estimated forfeiture rate. The fair value of each option award with time-based vesting provisions is estimated on the date of grant using the Black-Scholes option pricing model. The determination of fair value using the Black-Scholes option pricing model is affected by our stock price as well as assumptions regarding a number of complex and subjective variables, including expected stock price volatility, risk-free interest rate, expected dividends and projected employee stock option behaviors. The fair value of each option award with market-based vesting provisions is estimated on the date of grant using a Monte Carlo simulation. The determination of fair value using a Monte Carlo simulation is affected by our stock price as well as assumptions regarding a number of complex and subjective variables, including expected stock price volatility, risk-free interest rate, expected dividends and projected employee stock option behaviors. Expected volatilities are based on the Company’s historical volatility, which management believes represents the most accurate basis for estimating expected future volatility under the current circumstances. Navidea uses historical data to estimate forfeiture rates. The expected term of stock options granted is based on the vesting period and the contractual life of the options. The risk-free rate is based on the U.S. Treasury yield in effect at the time of the grant. The assumptions used to calculate the fair value of stock option awards granted during the years ended December 31, 2019 and 2018 are noted in the following table:
The portion of the fair value of stock-based awards that is ultimately expected to vest is recognized as compensation expense over either (
1 ) the requisite service period or (2 ) the estimated performance period. Restricted stock awards are valued based on the closing stock price on the date of grant and amortized ratably over the estimated life of the award. Restricted stock may vest based on the passage of time, or upon occurrence of a specific event or achievement of goals as defined in the grant agreements. In such cases, we record compensation expense related to grants of restricted stock based on management’s estimates of the probable dates of the vesting events. Stock-based awards that do not vest because the requisite service period is not met prior to termination result in reversal of previously recognized compensation cost. See Note 6.

Revenue [Policy Text Block] |
We also earn revenues related to our licensing and distribution agreements. The consideration we are eligible to receive under our licensing and distribution agreements typically includes upfront payments, reimbursement for research and development costs, milestone payments, and royalties. Each licensing and distribution agreement is unique and requires separate assessment in accordance with current accounting standards. See Note

Income Tax, Policy [Policy Text Block] |
Current accounting standards include guidance on the accounting for uncertainty in income taxes recognized in the financial statements. Such standards also prescribe a recognition threshold and measurement model for the financial statement recognition of a tax position taken, or expected to be taken, and provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. The Company believes that the ultimate deductibility of all tax positions is highly certain, although there is uncertainty about the timing of such deductibility. As a result,
no December 31, 2019 or 2018 and we do not expect any significant changes in the next twelve months. Should we need to accrue interest or penalties on uncertain tax positions, we would recognize the interest as interest expense and the penalties as a selling, general and administrative expense. As of December 31, 2019, tax years 2016 -2019 remained subject to examination by federal and state tax authorities. See Note 16.

New Accounting Pronouncements, Policy [Policy Text Block] |
In July 2018, the FASB issued ASU No. 2018 -10, Codification Improvements to Topic , and ASU 842, LeasesNo. 2018 -11, Targeted Improvements to Topic . ASU 842, Leases2018 -10 updates Topic 842 in order to clarify narrow aspects of the guidance issued in ASU 2016 -02, Leases (Topic . ASU 842 )2018 -11 provides entities with an additional (and optional) transition method to adopt the new leases standard. Under this new transition method, an entity initially applies the new leases standard at the adoption date and recognizes a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Consequently, an entity’s reporting for the comparative periods presented in the financial statements in which it adopts the new leases standard will continue to be in accordance with current U.S. GAAP (Topic 840, Leases ). An entity that elects this transition method must provide the required Topic 840 disclosures for all periods that continue to be in accordance with Topic 840. The amendments in ASU 2018 -10 and ASU 2018 -11 are effective when ASU 2016 -02 is effective, for fiscal years beginning after December 15, 2018.
The Company adopted ASU 2016 -02, ASU 2018 -10 and ASU 2018 -11 effective January 1, 2019 using the cumulative-effect adjustment transition method, which applies the provisions of the standard at the effective date without adjusting the comparative periods presented. Related to the adoption of these standards, the Company made a short-term lease accounting policy election allowing lessees to not recognize right-of-use assets and liabilities for leases with an initial term of 12 months or less.The adoption of ASU 2016 -02 resulted in the recognition of operating lease right-of-use assets and related lease liabilities of approximately $407,000 on the consolidated balance sheet as of January 1, 2019 related to our leases that were previously classified as operating leases, primarily for office space. The adoption of ASU 2016 -02 did not materially impact our operating results or liquidity. Disclosures related to the amount, timing and uncertainty of cash flows arising from leases are included in Note 13.
In June 2018, the FASB issued ASU No. 2018 -07, Compensation—Stock Compensation (Topic
718 ):
Improvements to Nonemployee Share-Based Payment Accounting . ASU 2018 -07 expands the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. An entity should apply the requirements of Topic 718 to nonemployee awards except for specific guidance on inputs to an option pricing model and the attribution of cost. ASU 2018 -07 specifies that Topic 718 applies to all share-based payment transactions in which a grantor acquires goods or services to be used or consumed in a grantor’s own operations by issuing share-based payment awards, and that Topic 718 does not apply to share-based payments used to effectively provide (1 ) financing to the issuer or (2 ) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under Topic 606, Revenue from Contracts with Customers . ASU 2018 -07 is effective for public business entities for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year. The adoption of ASU 2018 -07 did not have a significant impact on our consolidated financial statements.In July 2018, the FASB issued ASU No. 2018 -09, Codification Improvements . ASU 2018 -09 updates a variety of topics in order to clarify, correct errors, or make minor improvements to the Codification, making it easier to understand and easier to apply by eliminating inconsistencies and providing clarifications. Certain amendments in ASU 2018 -09 were effective upon issuance, others are effective for annual periods beginning after December 15, 2018 for public business entities, and some have been made to recently issued guidance and will be subject to the effective dates within the relevant guidance. The adoption of ASU 2018 -09 did not have a significant impact on our consolidated financial statements.
In
December 2019, the FASB issued ASU No. 2019 -12, Income Taxes (Topic
740 ):
Simplifying the Accounting for Income Taxes . ASU 2019 -12 is intended to improve consistent application and simplify the accounting for income taxes. ASU 2019 -12 removes certain exceptions to the general principles in Topic 740 and clarifies and amends existing guidance. ASU 2019 -12 is effective for annual and interim reporting periods beginning after December 12, 2020, with early adoption permitted. We do not expect the adoption of ASU 2019 -12 to have a material impact on our consolidated financial statements. |
