Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes During the three months ended March 31, 2014 and 2013, we recognized income tax expense of $438.7 and $410.2, respectively, which represents effective tax rates of 38.8% and 32.0%, respectively. The increase in income tax expense and the effective tax rate in 2014 was primarily due to the non-tax deductible HIP Fee effective January 1, 2014 resulting in additional expense of $80.5, partially offset by lower income before income taxes, favorable discrete tax adjustments related to state income tax audits including refund claims filed, and adjustments to state deferred tax liabilities resulting from a decrease in the Indiana statutory income tax rate. The lower effective rate in the three months ended March 31, 2013 resulted primarily from the inclusion of Amerigroup in our state apportionment calculations, which produced a lower effective state tax rate.
