Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Fluctuations in our provision for income taxes as a percentage of pre-tax earnings (“effective tax rate”) are due to changes in international and U.S. state effective tax rates and discrete items. During the three months ended March 31, 2014, the effective tax rate of 38.0 percent was impacted by net unfavorable discrete items of $5 million, which increased the rate by 1.0 percentage point. The discrete items include the unfavorable impact of remeasurement of unrecognized tax benefits ($5 million). During the nine months ended March 31, 2014, the effective tax rate of 35.5 percent was impacted by net favorable discrete items of $18 million, which reduced the rate by 1.2 percentage points. The discrete items include the favorable impact of the settlement of federal and state tax controversies ($67 million) and release of valuation allowance ($12 million) and the unfavorable impact of remeasurement of unrecognized tax benefits ($61 million). During the three and nine months ended March 31, 2013, the effective tax rates of 22.7 percent and 32.7 percent were impacted by net favorable discrete items of $57 million and $51 million, which decreased the rates by 12.7 and 3.7 percentage points, respectively. The discrete items for the three and nine months ended March 31, 2013 include the favorable impact of revaluation of the deferred tax liability and related interest on unrepatriated foreign earnings as a result of an agreement with tax authorities ($64 million), partially offset by unfavorable amounts related to remeasuring unrecognized tax benefits. We had $539 million and $650 million of unrecognized tax benefits at March 31, 2014 and June 30, 2013, respectively. The March 31, 2014 and June 30, 2013 balances include $348 million and $371 million, respectively, of unrecognized tax benefits that, if recognized, would have an impact on the effective tax rate. The remaining unrecognized tax benefits relate to tax positions for which ultimate deductibility is highly certain but for which there is uncertainty as to the timing of such deductibility. Recognition of these tax benefits would not affect our effective tax rate. We include the full amount of unrecognized tax benefits in deferred income taxes and other liabilities in the condensed consolidated balance sheets. We recognize accrued interest and penalties related to unrecognized tax benefits in the provision for income taxes. At March 31, 2014 and June 30, 2013 we had $147 million and $198 million, respectively, accrued for the payment of interest and penalties. These balances are gross amounts before any tax benefits and are included in deferred income taxes and other liabilities in the condensed consolidated balance sheets. It is reasonably possible that there could be a change in the amount of unrecognized tax benefits within the next 12 months due to activities of the U.S. Internal Revenue Service ("IRS") or other taxing authorities, including proposed assessments of additional tax, possible settlement of audit issues, reassessment of existing unrecognized tax benefits or the expiration of applicable statutes of limitations. We estimate that the range of the possible change in unrecognized tax benefits within the next 12 months is a net decrease of approximately zero to $90 million, exclusive of penalties and interest. We file income tax returns in the U.S. federal jurisdiction, various U.S. state jurisdictions and various foreign jurisdictions. We are subject to audit by the IRS for fiscal years 2006 through the current fiscal year. We are generally subject to audit by taxing authorities in various U.S. state and foreign jurisdictions for fiscal years 2003 through the current fiscal year. During the nine months ended March 31, 2014, the IRS closed audits of fiscal years 2003 through 2005. The IRS is currently conducting audits of fiscal years 2006 through 2010, and our transfer pricing arrangements continue to be under consideration as part of these audits. While the IRS has made and could make proposed adjustments to our transfer pricing arrangements, or other matters, we are defending our reported tax positions, and have accounted for the unrecognized tax benefits associated with our tax positions. We are a party to a tax matters agreement with CareFusion Corporation ("CareFusion"), under which CareFusion is obligated to indemnify us for certain tax exposures and transaction taxes prior to our fiscal 2010 spin-off of CareFusion. The indemnification receivable was $203 million and $186 million at March 31, 2014 and June 30, 2013, respectively, and is included in other assets in the condensed consolidated balance sheets.
