Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements include the accounts of Holdings and its direct and indirect wholly-owned subsidiaries, including Progenics, and have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, these condensed consolidated financial statements do not include all of the information and notes required by generally accepted accounting principles in the United States of America (“U.S. GAAP”) for complete financial statements. In the opinion of management, all adjustments (consisting of normal and recurring adjustments) considered necessary for a fair statement have been included. The results of operations for the three and six months ended June 30, 2022 are not necessarily indicative of the results that may be expected for the year ended December 31, 2022 or any future period. The condensed consolidated balance sheet at December 31, 2021 has been derived from the audited consolidated financial statements at that date but does not include all the information and notes required by U.S. GAAP for complete financial statements. These condensed consolidated financial statements and accompanying notes should be read in conjunction with the consolidated financial statements and notes thereto included in Item 8 of the Company’s most recent Annual Report on Form 10-K for the year ended December 31, 2021 filed with the Securities Exchange Commission (“SEC”) on February 24, 2022. Progenics Acquisition On June 19, 2020 (the “Closing Date”), pursuant to the Amended and Restated Agreement and Plan of Merger, dated as of February 20, 2020 (the “Merger Agreement”), by and among Holdings, Plato Merger Sub, Inc., a wholly-owned subsidiary of Holdings (“Merger Sub”), and Progenics, Holdings completed the acquisition of Progenics by means of a merger of Merger Sub with and into Progenics, with Progenics surviving such merger as a wholly-owned subsidiary of Holdings (the “Progenics Acquisition”). Subsequently, on June 22, 2020, Holdings contributed all of the capital stock of Progenics to LMI, thereby making Progenics an indirect subsidiary of Holdings. In accordance with the Merger Agreement, at the effective time of the Progenics Acquisition (the “Effective Time”), each share of Progenics common stock, par value $0.0013 per share, issued and outstanding immediately prior to the Effective Time (other than shares of Progenics common stock owned by Holdings, Progenics or any of their wholly-owned subsidiaries) was automatically cancelled and converted into the right to receive (i) 0.31 (the “Exchange Ratio”) of a share of Holdings common stock, par value $0.01 per share, and (ii) one contingent value right (a “CVR”) tied to the financial performance of PyL (18F-DCFPyL), Progenics’ prostate-specific membrane antigen (“PSMA”) targeted imaging agent designed to visualize prostate cancer. This agent was approved by the U.S. Food and Drug Administration (“FDA”) on May 26, 2021 under the name PYLARIFY (piflufolastat F 18), and the commercial launch of this agent began in June 2021. Each CVR entitles its holder to receive a pro rata share of aggregate cash payments equal to 40% of U.S. net sales generated by PYLARIFY in 2022 and 2023 in excess of $100.0 million and $150.0 million, respectively. In no event will the Company’s aggregate payments in respect of the CVRs, together with any other non-stock consideration treated as paid in connection with the Progenics Acquisition, exceed 19.9% of the total consideration the Company pays in the Progenics Acquisition. Based on the Company’s current projections of 2022 PYLARIFY net sales, the Company believes that all of its aggregate payment obligations under the CVRs (which the Company currently estimates could be approximately $99.7 million) will become payable in the first half of 2023, although the Company can give no assurances to that effect. As a result of the acquisition, Holdings issued 26,844,877 shares of Holdings common stock and 86,630,633 CVRs to former Progenics stockholders and option holders.

The Company applies the same revenue recognition policies and judgments for all its principal products. (2) The Company recognized $24.0 million license revenue in the first quarter of 2022 related to an agreement with Novartis Pharma AG. The Company classifies its revenues into three product categories: precision diagnostics, radiopharmaceutical oncology, and strategic partnerships and other revenue. Precision diagnostics includes DEFINITY, TechneLite and other diagnostic imaging products. Radiopharmaceutical oncology consists primarily of PYLARIFY and AZEDRA. Strategic partnerships and other revenue includes strategic partnerships and other arrangements related to other products of the Company, such as royalty revenue from our license of RELISTOR. On January 31, 2022, the Company entered into a global settlement agreement with Novartis Pharma AG (“Novartis”), Advanced Accelerator Applications USA, Inc. (“AAA”), Endocyte, Inc. (“Endocyte”) and their affiliates (the “Novartis Agreement”) to settle certain disputes between the parties. Under the Novartis Agreement, Novartis agreed to make a lump sum payment to the Company, as well as to reimburse the Company for certain fees and expenses in connection with certain German litigation, and the Company agreed to license certain intellectual property to Novartis. In addition, the Company agreed to supply PYLARIFY for clinical purposes at an arms-length value which will be recorded revenue in the future as product is provided. In accordance with the Company's ASC 606, Revenue from Contracts with Customers , assessment, Novartis is considered to be a customer. The Company determined that the $24.0 million constituted a single element which was satisfied on the date of the execution of the Novartis Agreement. The Company determined that the license of intellectual property carried a fair value of $24.0 million. As such, the Company assigned the value to the fair value of the license, which constitutes the entire transaction price and does not require further allocation. The Company determined that the $24.0 million represented the point at which the licensee was able to use and benefit from the license and recognized revenue when the license was granted to Novartis upon execution of the Novartis Agreement. The Company recognized the $24.0 million fee as revenue on its consolidated statement of operations for the quarter ended March 31, 2022. The Company received the $24.0 million payment in April 2022. Revenue by product category on a net basis is as follows: Three Months Ended Six Months Ended (in thousands) 2022 2021 2022 2021 DEFINITY $ 62,306 $ 59,842 $ 120,634 $ 115,813 TechneLite 19,440 23,772 42,045 46,572 Other precision diagnostics 5,363 6,742 10,628 13,726 Total precision diagnostics 87,109 90,356 173,307 176,111 PYLARIFY 130,232 273 223,009 273 Other radiopharmaceutical oncology 928 2,539 2,255 4,039 Total radiopharmaceutical oncology 131,160 2,812 225,264 4,312 Strategic partnerships and other revenue 5,454 7,896 34,032 13,150 Total revenues $ 223,723 $ 101,064 $ 432,603 $ 193,573 The Company’s performance obligations are typically part of contracts that have an original expected duration of one year or less. As such, the Company is not disclosing the aggregate amount of the transaction price allocated to performance obligations that are unsatisfied (or partially satisfied) as of the end of the reporting period.

Fair Value of Financial Instrum

Fair Value of Financial Instruments	6 Months Ended

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. In order to increase consistency and comparability of fair value measurements, financial instruments are categorized based on a hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three broad levels, which are described below: • Level 1 — Inputs are unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date. • Level 2 — Inputs include quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (i.e., interest rates, yield curves, etc.) and inputs that are derived principally from or corroborated by observable market data by correlation or other means (market corroborated inputs). • Level 3 — Unobservable inputs that reflect a Company’s estimates about the assumptions that market participants would use in pricing the asset or liability. The Company develops these inputs based on the best information available, including its own data. The Company’s financial assets and liabilities measured at fair value on a recurring basis consist of money market funds, interest rate swaps, a contingent receivable and contingent consideration liabilities. The Company invests excess cash from its operating cash accounts in overnight investments and reflects these amounts in cash and cash equivalents in the condensed consolidated balance sheets at fair value using quoted prices in active markets for identical assets. The fair value of the interest rate swaps is determined based on observable market-based inputs, including interest rate curves and reflects the contractual terms of these instruments, including the period to maturity. Please refer to Note 13, “Derivative Instruments”, for further details on the interest rate swaps. The Company recorded a contingent receivable and the contingent consideration liabilities resulting from the Progenics Acquisition at fair value based on inputs that are not observable in the market. The tables below present information about the Company’s assets and liabilities measured at fair value on a recurring basis: June 30, 2022 (in thousands) Total Fair Level 1 Level 2 Level 3 Assets: Money market $ 29,836 $ 29,836 $ — $ — Interest rate swaps 4,248 — 4,248 — Contingent receivable 7,700 — — 7,700 Total assets $ 41,784 $ 29,836 $ 4,248 $ 7,700 Liabilities: Contingent consideration liabilities $ 111,500 $ — $ — $ 111,500 Total liabilities $ 111,500 $ — $ — $ 111,500 December 31, 2021 (in thousands) Total Fair Level 1 Level 2 Level 3 Assets: Money market $ 40,140 $ 40,140 $ — $ — Interest rate swaps 357 — 357 — Contingent receivable 9,300 — — 9,300 Total assets $ 49,797 $ 40,140 $ 357 $ 9,300 Liabilities: Contingent consideration liabilities $ 86,200 $ — $ — $ 86,200 Total liabilities $ 86,200 $ — $ — $ 86,200 During the three and six months ended June 30, 2022, there were no transfers into or out of Level 3. As part of the Progenics Acquisition, the Company acquired the right to receive certain future milestone and royalty payments due to Progenics from CytoDyn Inc. related to a prior sale of certain intellectual property. The Company has the right to receive $5.0 million upon regulatory approval and a 5% royalty on net sales of approved products. The Company considers the contingent receivable a Level 3 instrument (one with significant unobservable inputs) in the fair value hierarchy. The estimated fair value was determined based on probability adjusted discounted cash flows that included significant estimates and assumptions pertaining to regulatory events and sales targets. The most significant unobservable inputs are the probabilities of achieving regulatory approval of the development projects and subsequent commercial success. As part of the Progenics Acquisition, the Company issued CVRs and recorded the fair value as part of consideration transferred. Each CVR entitles its holder to receive a pro rata share of aggregate cash payments equal to 40% of U.S. net sales generated by PYLARIFY in 2022 and 2023 in excess of $100.0 million and $150.0 million, respectively, subject to a maximum cap. Refer to Note 1, “Basis of Presentation” for further details on the CVRs. The Company considers the contingent consideration liabilities relating to the CVRs a Level 3 instrument (one with significant unobservable inputs) in the fair value hierarchy. The estimated fair value of these had been determined based on Monte Carlo simulation models that included significant estimates and assumptions pertaining to commercialization events and sales targets. Because of revised revenue forecasts for the balance of 2022, the Company updated the valuation technique for the CVRs from the Monte Carlo simulation model to a probability adjusted discounted cash flow model as the Company currently expects to pay out the full amount of the CVRs from available cash in the first half of 2023 based on U.S. net sales generated by PYLARIFY in 2022 and, under either valuation technique, the estimated liability would be approximately the same. The Company also assumed contingent consideration liabilities related to a previous acquisition completed by Progenics in 2013 (“2013 Acquisition”). These contingent consideration liabilities include potential payments of up to $70.0 million if the Company attains certain net sales targets primarily for AZEDRA and 1095 and a $5.0 million 1095 commercialization milestone. Additionally, there is a potential payment of up to $10.0 million related to a 1404 commercialization milestone. The Company’s total potential payments related to the 2013 Acquisition are approximately $85.0 million. The Company considers the contingent consideration liabilities relating to the 2013 Acquisition each a Level 3 instrument (one with significant unobservable inputs) in the fair value hierarchy. The estimated fair value of these was determined based on probability adjusted discounted cash flows and Monte Carlo simulation models that included significant estimates and assumptions pertaining to commercialization events and sales targets. The most significant unobservable inputs with respect to 1095 and 1404 are the probabilities of achieving regulatory approval of those development projects and subsequent commercial success. Significant changes in any of the probabilities of success, the probabilities as to the periods in which sales targets and milestones will be achieved, discount rates or underlying revenue forecasts would result in a significantly higher or lower fair value measurement. The Company records the contingent consideration liability at fair value with changes in estimated fair values recorded in general and administrative expenses in the condensed consolidated statements of operations. The Company can give no assurance that the actual amounts paid, if any, in connection with the contingent consideration liabilities, including the CVRs, will be consistent with any recurring fair value estimate of such contingent consideration liabilities. The following tables summarize quantitative information and assumptions pertaining to the fair value measurement of assets and liabilities using Level 3 inputs at June 30, 2022.

The Company expects to make all applicable cash payments related to the CVRs in the first half of 2023. As of June 30, 2022, the Company had $99.7 million in current liabilities to account for the expected payments related to the CVRs.

Income Tax Disclosure [Abstract]
Income Taxes	Income TaxesThe Company calculates income taxes at the end of each reporting period based on the estimated effective tax rate for the full year, adjusted for any discrete events which are recorded in the period they occur. Cumulative adjustments to the tax provision are recorded in the reporting period in which a change in the estimated annual effective tax rate is determined. The Company’s income tax expense is presented below: Three Months Ended Six Months Ended (in thousands) 2022 2021 2022 2021 Income tax expense (benefit) $ 18,987 $ (1,879) $ 33,926 $ 3,455 The Company regularly assesses its ability to realize its deferred tax assets. Assessing the realizability of deferred tax assets requires significant management judgment. In determining whether its deferred tax assets are more-likely-than-not realizable, the Company evaluated all available positive and negative evidence, and weighed the objective evidence and expected impact. The Company assessed the need for a valuation allowance against certain state tax credit carryforwards added through the Progenics Acquisition. The Company continues to retain other valuation allowances of $1.2 million against the net deferred tax assets of Lantheus MI UK Limited, its U.K. subsidiary, and $2.0 million against the net deferred tax assets of EXINI, its Sweden subsidiary. In connection with the Company’s acquisition of the medical imaging business from Bristol-Myers Squibb (“BMS”) in 2008, the Company recorded a liability for uncertain tax positions related to the acquired business and simultaneously entered into a tax indemnification agreement with BMS under which BMS agreed to indemnify the Company for any payments made to settle those uncertain tax positions with the state taxing authorities. Accordingly, a long-term receivable is recorded to account for the expected value to the Company of future indemnification payments to be paid on behalf of the Company by BMS, net of actual tax benefits received by the Company. The tax indemnification receivable is recorded within other long-term assets. In accordance with the Company’s accounting policy, the change in the tax liabilities, penalties and interest associated with these obligations (net of any offsetting federal or state benefit) is recognized within income tax expense. As these reserves change adjustments are included in income tax expense while the offsetting adjustment is included in other income. Assuming that the remaining receivable from BMS continues to be considered recoverable by the Company, there will be no effect on net income and no net cash outflows related to these liabilities. The Company finalized the accounting for the Progenics Acquisition for income taxes in the first quarter of 2021 resulting in a reduction of deferred tax assets, primarily related to state research credit carryforwards and an increase to goodwill of $2.6 million.

The assets were classified as held for sale and the Company determined that the fair value of the net assets being sold significantly exceeded the carrying value as of December 31, 2020. The transaction was consummated on January 29, 2021. The purchase price for the stock sale was $18.0 million in cash, including a holdback amount of $1.8 million which the Company received during the first quarter of 2022; the purchase price also included a working capital adjustment. The SPA contains customary representations, warranties and covenants by each of the parties. Subject to certain limitations, the buyer will be indemnified for damages resulting from breaches or inaccuracies of the Company’s representations, warranties and covenants in the SPA. The Company determined that this sale of certain net assets did not constitute a strategic shift that had a major effect on the Company’s operations or financial results.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	Derivative Instruments The Company uses interest rate swaps to reduce the variability in cash flows associated with a portion of the Company’s forecasted interest payments on its variable rate debt. In March 2020, the Company entered into interest rate swap contracts to fix the LIBOR rate on a notional amount of $100.0 million through May 31, 2024. The average fixed LIBOR rate on the interest rate swaps is approximately 0.82%. This agreement involves the receipt of floating rate amounts in exchange for fixed rate interest payments over the life of the agreement without an exchange of the underlying principal amount. The interest rate swaps were designated as cash flow hedges. In accordance with hedge accounting, the interest rate swaps are recorded on the Company’s condensed consolidated balance sheets at fair value, and changes in the fair value of the swap agreements are recorded to other comprehensive loss and reclassified to interest expense in the period during which the hedged transaction affected earnings or it will become probable that the forecasted transaction would not occur. At June 30, 2022, accumulated other comprehensive income included $2.3 million of pre-tax deferred gains that are expected to be reclassified to earnings during the next 12 months.

The costs and outcome of litigation, regulatory or other proceedings cannot be predicted with certainty, and some lawsuits, claims, actions or proceedings may be disposed of unfavorably to the Company and could have a material adverse effect on the Company’s results of operations or financial condition. In addition, intellectual property disputes often have a risk of injunctive relief which, if imposed against the Company, could materially and adversely affect its financial condition or results of operations. If a matter is both probable to result in material liability and the amount of loss can be reasonably estimated, the Company estimates and discloses the possible material loss or range of loss. If such loss is not probable or cannot be reasonably estimated, a liability is not recorded in its condensed consolidated financial statements. As of June 30, 2022, the Company did not have any material ongoing litigation in which the Company was a party.

Segment Reporting [Abstract]
Segment Information	Segment InformationIn the first quarter of fiscal year 2021, the Company completed the evaluation of its operating and reporting structure, including the impact on the Company’s business of the acquisition of Progenics described in Note 1, and the sale of the Puerto Rico subsidiary in the first quarter, which resulted in a change in operating and reportable segments. The Company now operates as one business segment: the development, manufacture and sale of innovative imaging diagnostics, radiotherapeutics, and artificial intelligence solutions designed to enable clinicians to Find, Fight and Follow disease to deliver better patient outcomes. This conclusion reflects the Company’s focus on the performance of the business on a consolidated worldwide basis. The results of this operating segment are regularly reviewed by the Company’s chief operating decision maker, the President and Chief Executive Officer. The Company’s chief operating decision maker does not manage any part of the Company separately, and the allocation of resources and assessment of performance are based on the Company’s consolidated operating results.
