| Nature of Operations [Text Block] |
Enzon Pharmaceuticals, Inc. (together with its subsidiaries, “Enzon” or the “Company”) receives royalty revenues from existing licensing arrangements with other companies primarily related to sales of four marketed drug products, namely, PegIntron ®, Sylatron ®, Macugen ® and CIMZIA ®. The primary source of the Company’s royalty revenues is sales of PegIntron, which is marketed by Merck & Co., Inc. (“Merck”). The Company currently has no clinical operations and limited corporate operations. The Company has no intention of resuming any clinical development activities or acquiring new sources of royalty revenues. Royalty revenues from sales of PegIntron accounted for approximately 44% and 73% of the Company’s total royalty revenues for the three months ended March 31, 2017 and 2016, respectively, and approximately 64% and 80% of the Company’s total royalty revenues for the years ended December 31, 2016 and 2015, respectively. The Company was previously dedicated to the research and development of innovative therapeutics for patients with high unmet medical needs. Beginning in December 2012, the Company’s Board of Directors (the “Board”), with outside consultants, began a review of the possible sale or disposition of one or more corporate assets or a sale of the Company. At that time, the Company suspended substantially all clinical development activities with a goal of conserving capital and maximizing value returned to the Company’s stockholders. By April 2013, the review did not result in a definitive offer to acquire the Company or all or substantially all of the Company’s assets. At the same time, the Company announced that its Board intended to distribute excess cash, expected to arise from ongoing royalty revenues, in the form of periodic dividends to stockholders. In June 2015, the Company delivered notice to Nektar Therapeutics, Inc. (“Nektar”) asserting a breach of our Cross-License and Option Agreement with Nektar for Nektar’s failure to pay a post-patent expiration immunity fee that the Company believes became payable under such agreement. To date, Nektar has disputed the Company’s claim to an immunity fee. On August 14, 2015, the Company filed a summons and complaint against Nektar in the Supreme Court of the State of New York for breach of contract. On October 23, 2015, Nektar filed a motion to dismiss the complaint. On February 2, 2016, the Court granted Nektar’s motion to dismiss the complaint. The Company appealed this dismissal and on October 25, 2016 the Appellate Division reversed and remanded the case to the trial court for further proceedings. On November 28, 2016, Nektar served an amended answer and counterclaim alleging that the patents at issue are unenforceable. On March 14, 2017, the Court denied the Company’s motion to dismiss Nektar’s counterclaim. While the Company believes that an immunity fee is currently due and payable by Nektar and the Company intends to continue to pursue this claim, the outcome of such dispute is uncertain and there can be no assurance that the Company will be able to collect, in full or in part, the immunity fee or any future payments related thereto from Nektar. As such, no amounts have been recorded as of March 31, 2017. On February 4, 2016, the Company’s board of directors adopted a Plan of Liquidation and Dissolution, the implementation of which has been postponed. (See Note 10.) In March 2017, Merck notified the Company that it had overpaid the Company in 2016 for royalties on U.S. sales of PegIntron, the right to which had expired in February 2016. Accordingly, the Company recorded a liability to Merck in the amount of approximately $770,000 as of December 31, 2016. In March 2017, Merck withheld royalties payments due of approximately $636,000 in order to recoup a portion of its 2016 overpayment. Accordingly, the Company recorded a corresponding reduction of the accounts payable liability. See Note 11. |

Interim Financial Statements The accompanying unaudited condensed consolidated financial statements have been prepared from the books and records of the Company in accordance with United States generally accepted accounting principles (U.S. GAAP) for interim financial information and Rule 10-01 of Regulation S-X promulgated by the U.S. Securities and Exchange Commission. Accordingly, these financial statements do not include all of the information and footnotes required for complete annual financial statements. Interim results are not necessarily indicative of the results that may be expected for the full year. Interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016. Principles of Consolidation The condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated as part of the consolidation. Use of Estimates The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect reported amounts of assets and liabilities, disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. These estimates include legal and contractual contingencies and income taxes. Although management bases its estimates on historical experience and various other assumptions that are believed to be reasonable under the circumstances, actual results could differ from these estimates. Revenues Royalties under the Company’s license agreements with third-parties and pursuant to the sale of its former specialty pharmaceutical business are recognized when reasonably determinable and earned through the sale of the product by the third-party and collection is reasonably assured. Notification from the third-party licensee of the royalties earned under the license agreement is the basis for royalty revenue recognition. This information generally is received from the licensees in the quarter subsequent to the period in which the sales occur. |

| New Accounting Pronouncements and Changes in Accounting Principles [Abstract] | ||||
| Description of New Accounting Pronouncements Not yet Adopted [Text Block] |
In January 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business, in an effort to clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The amendments of this ASU are effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The adoption of this guidance is not expected to have a material impact on our financial statements. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606); Narrow-Scope Improvements and Practical Expedients. ASU 2014-09 provides for a single five-step model to be applied to all revenue contracts with customers, as well as requiring additional financial statement disclosures that will enable users to understand the nature, amount, timing and uncertainty of revenue and cash flows relating to customer contracts. Companies have an option to use either a retrospective approach or cumulative effect adjustment approach to implement the standard. As amended by ASU 2015- 14, issued in August 2015, this ASU is effective fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. We do not believe the adoption of this ASU will have a material effect on the Company’s consolidated financial position and results of operations.

| Earnings Per Share [Text Block] |
Basic income per common share is computed by dividing the net income by the weighted average number of shares of common stock outstanding during the period. Restricted stock awards and restricted stock units (collectively, nonvested shares) are not considered to be outstanding shares until the service or performance vesting period has been completed. The diluted income per share calculation would normally involve adjusting both the denominator and numerator as described here if the effect is dilutive. The denominator would include both the weighted average number of shares of common stock outstanding and common stock equivalents. Dilutive common stock equivalents potentially include stock options and nonvested shares using the treasury stock method and shares issuable under the employee stock purchase plan. For purposes of calculating diluted earnings per common share, the denominator includes both the weighted-average number of shares of common stock outstanding and the number of common stock equivalents if the inclusion of such common stock equivalents is dilutive. Dilutive common stock equivalents potentially include stock options and nonvested shares using the treasury stock method and shares issuable under the employee stock purchase plan (ESPP). Income per common share information is as follows (in thousands, except per share amounts) for the three months ended March 31, 2017 and 2016:
At March 31, 2017 and 2016, there were 90,787 and 347,919 potentially dilutive securities outstanding that have been excluded from the calculation of dilutive weighted average shares outstanding, as they would be anti-dilutive . |

During the three months ended March 31, 2017, the Company recorded approximately $446,000 of income tax expense for U.S. federal and NJ state income tax, substantially all of which related to a reduction of the Company’s net deferred tax assets. After reducing its deferred tax assets by approximately $424,000 during the three months ended March 31, 2017 for operations during the quarter, the Company continues to provide a valuation allowance against all of its deferred tax assets except for NOLs expected to be utilized in the 2018 and 2019 tax years as the Company believes it is more likely than not that these remaining deferred tax assets will not be realized. Management of the Company will continue to assess the need for this valuation allowance and will make adjustments to it when appropriate. During the three months ended March 31, 2016, the Company recorded $1,028,000 of income tax expense for U.S. federal income tax, substantially all of which related to a reduction of the Company’s net deferred tax assets. Tax benefits of uncertain tax positions are recognized only if it is more likely than not that the Company will be able to sustain a position taken on an income tax return. The Company has no liability for uncertain tax positions. Interest and penalties, if any, related to unrecognized tax benefits, would be recognized as income tax expense. |

| Liquidation Basis of Accounting [Text Block] |
On February 4, 2016, the Company’s Board of Directors adopted a Plan of Liquidation and Dissolution (the “Plan of Liquidation and Dissolution”), pursuant to which the Company would, subject to obtaining requisite stockholder approval, be liquidated and dissolved in accordance with Sections 280 and 281 (a) of the General Corporation Law of the State of Delaware. In approving the Plan of Liquidation and Dissolution, the Company’s Board of Directors had considered, among other factors, the ability of the Company to obtain no-action relief from the SEC to suspend certain of the Company’s reporting obligations under the Securities Exchange Act of 1934, as amended, and the anticipated cost savings if such relief is granted by the SEC. Upon further review, the Company concluded that the SEC was unlikely to grant such relief to the Company in 2016. Accordingly, after further consideration, the Company’s Board of Directors determined that it would be fair, advisable and in the best interests of the Company and its stockholders to postpone seeking stockholder approval of the Plan of Liquidation and Dissolution until a later time to be determined by the Company’s Board of Directors. If dissolution and liquidation of the Company pursuant to the Plan of Liquidation and Dissolution are approved by the Company’s stockholders and implemented by management, it is expected that the Company’s corporate existence will continue for the purpose of winding up its business and affairs through the year 2021, consistent with the expiration of the Company’s existing license arrangements that generate its royalty revenues. The Company’s future royalty revenues are forecasted to aggregate approximately $10.1 million from the beginning of 2017 through the end of 2021. This forecast is based upon a variety of estimates and numerous assumptions made by the Company’s management with respect to, among other matters, forecasted sales of the drug products for which the Company has the right to receive royalties and other matters, many of which are difficult to predict, are subject to significant uncertainties, and are beyond the Company’s control. As a result, there can be no assurance that the estimates and assumptions upon which this forecast is based will prove accurate, that the projected results will be realized or that actual results will not be substantially higher or lower than forecasted. |

| Royalty Revenues and Accounts Payable [Text Block] |
In March 2017, Merck notified the Company that it had made a net overpayment to Enzon of approximately $770,000 in royalties during the second and third quarters of 2016. This was due to a previous misunderstanding regarding the date on which the Company’s right to receive royalties from U. S. sales of PegIntron expired, which Merck then advise had occurred in February 2016. Merck notified the Company that it intended to recover such overpayment from the Company by reducing future royalties to which the Company would otherwise be entitled from Merck until the full amount of the overpayment had been recouped. Accordingly, in the December 31, 2016 financial statements, the Company reduced its previously recorded revenues by the net $770,000 overpayment and recorded a corresponding liability to Merck in accounts payable. During the quarter ended March 31, 2017, Merck reported a net $636,000 of PegIntron royalties as being earned by the Company and withheld that amount as a partial recoupment. Consequently, the Company reported that amount as royalty revenues and reduced its liability to Merck by the same amount. |

| Use of Estimates, Policy [Policy Text Block] | Use of Estimates The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect reported amounts of assets and liabilities, disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. These estimates include legal and contractual contingencies and income taxes. Although management bases its estimates on historical experience and various other assumptions that are believed to be reasonable under the circumstances, actual results could differ from these estimates. |
|
| Revenue Recognition, Policy [Policy Text Block] | Revenues Royalties under the Company’s license agreements with third-parties and pursuant to the sale of its former specialty pharmaceutical business are recognized when reasonably determinable and earned through the sale of the product by the third-party and collection is reasonably assured.
