Summary Of Significant Accounting Policies [Abstract]
Basis Of Presentation	Basis of Presentation. Our condensed consolidated financial statements include the accounts of all majority-owned and controlled subsidiaries, and all significant intercompany amounts have been eliminated. References to "we", "our" and similar pronouns in this Quarterly Report on Form 10-Q refer to Cardinal Health, Inc. and its majority-owned and controlled subsidiaries unless the context requires otherwise. The results of businesses acquired or disposed of are included in the condensed consolidated financial statements from the effective date of the acquisition or up to the date of disposal. Our condensed consolidated financial statements have been prepared in accordance with the U.S. Securities and Exchange Commission ("SEC") instructions to Quarterly Reports on Form 10-Q and include all of the information and disclosures required by accounting principles generally accepted in the United States ("GAAP") for interim financial reporting. The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect amounts reported in the condensed consolidated financial statements and accompanying notes. Actual amounts may differ from these estimated amounts. In addition, operating results presented for this fiscal 2012 interim period are not necessarily indicative of the results that may be expected for the full fiscal year ending June 30, 2012. These condensed consolidated financial statements are unaudited and are presented pursuant to the rules and regulations of the SEC. Accordingly, the condensed consolidated financial statements included in this Quarterly Report on Form 10-Q for the quarter ended March 31, 2012 (this "Form 10-Q") should be read in conjunction with the audited consolidated financial statements and related notes contained in our Annual Report on Form 10-K for the fiscal year ended June 30, 2011, as updated by our Form 8-K/A filed on November 4, 2011 (the "Fiscal 2011 Financial Statements"). In our opinion, all adjustments necessary for a fair presentation of the condensed consolidated financial statements have been included. Except as disclosed elsewhere in this Form 10-Q, all such adjustments are of a normal and recurring nature.
