Final answer:
The PPACA mandates that the Medicare Part D prescription drug coverage gap, known as the "donut hole," must decrease until it is no more than 25%.
Step-by-step explanation:
The Patient Protection and Affordable Care Act (PPACA) has mandated that the "donut hole," the gap in Medicare Part D prescription drug coverage, must decrease each year until it reaches no more than 25% of the cost of drugs. The "donut hole" refers to a coverage gap during which beneficiaries must pay for their prescriptions out of pocket after they and their drug plan have spent a certain amount of money for covered drugs, but before the catastrophic coverage kicks in. This gap has been an issue because Medicare's lack of a prescription drug benefit was particularly hard on the elderly and disabled, who often require multiple medications.
