Accounting Policies [Abstract]
Basis of Presentation	Basis of PresentationThe accompanying unaudited consolidated financial statements include the accounts of Owens & Minor, Inc. and the subsidiaries it controls (we, us, or our) and contain all adjustments (which are comprised only of normal recurring accruals and use of estimates) necessary to conform with U.S. generally accepted accounting principles (GAAP). All significant intercompany accounts and transactions have been eliminated. The Movianto business represented a component that met accounting requirements to be classified as discontinued operations for the nine months ended September 30, 2020. In accordance with GAAP, the results of operations of the Movianto business are presented as discontinued operations through June 18, 2020 (the Divestiture Date) and, as such, have been excluded from continuing operations for the nine months ended September 30, 2020. With the exception of Note 3, the Notes to Consolidated Financial Statements reflect the continuing operations of Owens & Minor, Inc. and its subsidiaries. See Note 3 for additional information regarding discontinued operations. The results of operations for interim periods are not necessarily indicative of the results expected for the full year.

Cash, Cash Equivalents and Restricted Cash	Cash, Cash Equivalents and Restricted CashCash, cash equivalents and restricted cash includes cash and marketable securities with an original maturity or maturity at acquisition of three months or less. Cash, cash equivalents and restricted cash are stated at cost. Nearly all of our cash, cash equivalents and restricted cash are held in cash depository accounts in major banks in the United States, Europe, and Asia. Cash that is held by a major bank and has restrictions on its availability to us is classified as restricted cash. Restricted cash included in Other assets, net as of September 30, 2021 represents cash held in an escrow account as required by the Centers for Medicare & Medicaid Services (CMS) in conjunction with the Bundled Payments for Care Improvement (BPCI) initiatives.
Fair Value	The carrying amounts of cash and cash equivalents, accounts receivable and accounts payable reported in the consolidated balance sheets approximate fair value due to the short-term nature of these instruments. The carrying amount of restricted cash also approximates fair value due to its nature. The fair value of debt is estimated based on quoted market prices or dealer quotes for the identical liability when traded as an asset in an active market (Level 1) or, if quoted market prices or dealer quotes are not available, on the borrowing rates currently available for loans with similar terms, credit ratings, and average remaining maturities (Level 2). See Note 6 for the fair value of debt. The fair value of foreign currency contracts is determined based on the present value of expected future cash flows considering the risks involved, including non-performance risk, and using discount rates appropriate for the respective maturities. Observable Level 2 inputs are used to determine the present value of expected future cash flows. See Note 8 for the fair value of derivatives.
Segment Information	We periodically evaluate our application of accounting guidance for reportable segments and disclose information about reportable segments based on the way management organizes the enterprise for making operating decisions and assessing performance. We report our business under two segments: Global Solutions and Global Products. The Global Solutions segment includes our United States distribution businesses (Medical Distribution and Patient Direct), outsourced logistics and value-added services business. Global Products manufactures and sources medical surgical products through our production and kitting operations. We evaluate the performance of our segments based on their operating income excluding intangible amortization and acquisition-related and exit and realignment charges that, either as a result of their nature or size, would not be expected to occur as part of our normal business operations on a regular basis. Segment assets exclude inter-segment account balances as we believe their inclusion would be misleading and not meaningful. We believe all inter-segment sales are at prices that approximate market.
Recent Accounting Pronouncements	In December 2019, the FASB issued ASU No. 2019-12, Simplifying the Accounting for Income Taxes, which simplifies the accounting for income taxes, eliminates certain exceptions within ASC 740, Income Taxes, and clarifies certain aspects of the current guidance to promote consistency among reporting entities. Most amendments within the standard are required to be applied on a prospective basis, while certain amendments must be applied on a retrospective or modified retrospective basis. We adopted ASU No. 2019-12 effective beginning January 1, 2021. Its adoption did not have a material impact on our consolidated financial statements. In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments apply only to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The amendments are effective for all entities as of March 12, 2020 through December 31, 2022. Our current debt agreements contemplate a transition from LIBOR to another benchmark rate in the event that LIBOR ceases to exist. We do not expect the transition to have a material impact on our consolidated financial statements. In October 2020, the FASB issued ASU No. 2020-10, Codification Improvements, to improve consistency by amending the FASB Accounting Standards Codification (the Codification) to include all disclosure guidance in the appropriate disclosure sections. This ASU also clarifies application of various provisions in the Codification by amending and adding new headings, cross referencing to other guidance, and refining or correcting terminology. The amendments in this ASU do not change GAAP and, therefore, are not expected to result in a significant change in practice. We adopted ASU No. 2020-10 effective beginning January 1, 2021. Its adoption did not have a material impact on our consolidated financial statements. There have been no further changes in our significant accounting policies from those contained in our Annual Report on Form 10-K for the year ended December 31, 2020.

Reclassifications

Certain prior year amounts have been reclassified to conform to the current year presentation.

Use of Estimates

The preparation of consolidated financial statements in conformity with GAAP requires us to make assumptions and estimates that affect reported amounts and related disclosures. Actual results may differ from these estimates.

Cash, Cash Equivalents and Restricted Cash

Cash, Cash Equivalents and Restricted CashCash, cash equivalents and restricted cash includes cash and marketable securities with an original maturity or maturity at acquisition of three months or less. Cash, cash equivalents and restricted cash are stated at cost. Nearly all of our cash, cash equivalents and restricted cash are held in cash depository accounts in major banks in the United States, Europe, and Asia. Cash that is held by a major bank and has restrictions on its availability to us is classified as restricted cash.
