Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes We provide for income taxes for each interim period based on the estimated annual effective tax rate for the year, adjusting for discrete items in the quarter in which they arise. The annual effective tax rate before discrete items was 38.5% and 39.2% for the six months ended June 30, 2015 and June 30, 2014, respectively. The 2015 and 2014 annual effective tax rate differed from the statutory rate of 35.0% primarily due to the unfavorable impact of state income taxes, non-deductible equity charges, and other non-deductible expenditures, which were partially offset by the domestic production activities deduction. We recorded a gain of $3.4 million attributable to the increase in the fair value of Omnicell's 15% minority interest in Avantec which was revalued in conjunction with our purchase of the remaining 85% of Avantec shares. This gain was treated as a discrete item and excluded from profit-before-tax in calculating the annual effective tax rate for the six months ended June 30, 2015. The federal research and development credits law, which was extended through December 31, 2014, retroactively has not been extended to the end of 2015. As a result the annual effect tax rate for the six months ended June 30, 2015 and 2014 did not consider the effect of the federal research and development tax credit.

We provide for income taxes for each interim period based on the estimated annual effective tax rate for the year, adjusting for discrete items in the quarter in which they arise. The annual effective tax rate before discrete items was 38.5% and 39.2% for the six months ended June 30, 2015 and June 30, 2014, respectively. The 2015 and 2014 annual effective tax rate differed from the statutory rate of 35.0% primarily due to the unfavorable impact of state income taxes, non-deductible equity charges, and other non-deductible expenditures, which were partially offset by the domestic production activities deduction.

We recorded a gain of $3.4 million attributable to the increase in the fair value of Omnicell's 15% minority interest in Avantec which was revalued in conjunction with our purchase of the remaining 85% of Avantec shares. This gain was treated as a discrete item and excluded from profit-before-tax in calculating the annual effective tax rate for the six months ended June 30, 2015.

The federal research and development credits law, which was extended through December 31, 2014, retroactively has not been extended to the end of 2015. As a result the annual effect tax rate for the six months ended June 30, 2015 and 2014 did not consider the effect of the federal research and development tax credit.
