Medicaid Program; Multiple Source Drug Definition

On July 17, 2007, we published a final rule with comment period in the Federal Register that implemented provisions of the Deficit Reduction Act of 2005 pertaining to prescription drugs under the Medicaid program. In that rule, we finalized certain provisions of the Medicaid drug rebate program, including definitions concerning average manufacturer price, best price, single source drug, and multiple source drug. In this interim final rule with comment period, we are revising the definition of "multiple source drug" to better conform with the statutory provisions. This interim final rule with comment period solicits additional public comment on the revised definition of "multiple source drug."
