Who is responsible for Medicare eligibility?
The Social Security Administration (SSA) is responsible for determining Medicare eligibility, eligibility for and payment of Extra Help/Low Income Subsidy payments related to Parts C and D of Medicare, and collecting most premium payments for the Medicare program.
When did Medicare Part D start?
Medicare Part D went into effect on January 1, 2006. Anyone with Part A or B is eligible for Part D, which covers mostly self-administered drugs. It was made possible by the passage of the Medicare Modernization Act of 2003. To receive this benefit, a person with Medicare must enroll in a stand-alone Prescription Drug Plan (PDP) or public Part C health plan with integrated prescription drug coverage (MA-PD). These plans are approved and regulated by the Medicare program, but are actually designed and administered by various sponsors including charities, integrated health delivery systems, unions and health insurance companies; almost all these sponsors in turn use pharmacy benefit managers in the same way as they are used by sponsors of health insurance for those not on Medicare. Unlike Original Medicare (Part A and B), Part D coverage is not standardized (though it is highly regulated by the Centers for Medicare and Medicaid Services). Plans choose which drugs they wish to cover (but must cover at least two drugs in 148 different categories and cover all or "substantially all" drugs in the following protected classes of drugs: anti-cancer; anti-psychotic; anti-convulsant, anti-depressants, immuno-suppressant, and HIV and AIDS drugs). The plans can also specify with CMS approval at what level (or tier) they wish to cover it, and are encouraged to use step therapy. Some drugs are excluded from coverage altogether and Part D plans that cover excluded drugs are not allowed to pass those costs on to Medicare, and plans are required to repay CMS if they are found to have billed Medicare in these cases.
