Final answer:
The late payment for a prescription drug D program entails penalties for not paying Medicare Part D premiums on time, a program that helps the elderly and disabled afford prescription medications, influenced by AARP's advocacy.
Step-by-step explanation:
The late payment for a prescription drug D program refers to the consequences faced by enrollees who do not pay their Medicare Part D premiums on time. Medicare Part D is a prescription drug benefit program that was created as a part of the Medicare Prescription Drug and Modernization Act of 2003. This program was specifically designed to assist the elderly and disabled in affording their medications, acknowledging the financial burden prescription drugs can have on these groups.
Under this program, individuals pay an annual premium and deductible, after which the federal government covers 75 percent of their prescription drug costs up to a certain limit ($2,250 as per the initial program structure). The formation of this benefit was largely due to the advocacy of the American Association for Retired Persons (AARP), which was more successful in representing the interests of the elderly compared to the advocacy for those without health insurance. The costs of the Medicare prescription drug benefit have been significantly high, contributing to debates about its economic implications and overall effectiveness.
