The Medicare Prescription Drug, Improvement, and Modernization Act (MMA) of 2003 ( PL 108-173 ) establishes a voluntary prescription drug benefit for Medicare beneficiaries under a new Medicare Part D that begins January 1, 2006. Medicare Part D provides medical coverage of prescription drugs to Medicaid eligible individuals who are also eligible for Medicare Part A or enrolled in Medicare Part B. It also provides for extra help with premiums, deductibles and co-payments under a low-income subsidy (LIS) for individuals who meet an income and asset test as described at 42 CFR 423.773.
