Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis Of Presentation [Text Block]	Note 1. BASIS OF PRESENTATION Bristol-Myers Squibb Company (which may be referred to as Bristol-Myers Squibb, BMS or the Company) prepared these unaudited consolidated financial statements following the requirements of the Securities and Exchange Commission (SEC) and United States (U.S.) generally accepted accounting principles (GAAP) for interim reporting. Under those rules, certain footnotes and other financial information that are normally required for annual financial statements can be condensed or omitted. The Company is responsible for the consolidated financial statements included in this Form 10-Q. These consolidated financial statements include all normal and recurring adjustments necessary for a fair presentation of the financial position at March 31, 2013 and December 31, 2012, and the results of operations and cash flows for the three months ended March 31, 2013 and 2012. All intercompany balances and transactions have been eliminated. Material subsequent events are evaluated and disclosed through the report issuance date. These unaudited consolidated financial statements and the related notes should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 2012 included in the Annual Report on Form 10-K. Certain prior period amounts have been reclassified to conform to the current period presentation. The presentation of depreciation and amortization in the consolidated statements of cash flows includes the depreciation of property, plant and equipment, the amortization of intangible assets and deferred income. The provision for restructuring, equity in net income of affiliates, and litigation expense, net, previously presented separately on the consolidated statements of earnings, are currently presented as components of other (income)/expense. Revenues, expenses, assets and liabilities can vary during each quarter of the year. Accordingly, the results and trends in these unaudited consolidated financial statements may not be indicative of full year operating results. The preparation of financial statements requires the use of management estimates and assumptions. The most significant assumptions are employed in estimates used in determining the fair value and potential impairment of intangible assets; sales rebate and return accruals; legal contingencies; income taxes; and pension and postretirement benefits. Actual results may differ from estimated results.
