To enroll in a Part D plan you must be enrolled in either Part A or Part B of Original Medicare. To qualify for Original Medicare you must be 65 or over (and meet the residence and work requirements) or have been on Social Security Disability Income (SSDI) for 25 months.
ESRD Exception – Medicare Part B covers transplant drugs after a covered transplant, and most of the drugs you get for dialysis. However, Part B doesn’t cover prescription drugs for other health conditions you may have, like high blood pressure. Medicare offers prescription drug coverage (Part D) to help you with the costs of your drugs not covered by Part B.
ALS Exception – The 24-month waiting period is waived for Medicare coverage for disabled individuals medically determined to have Amyotrophic Lateral Sclerosis (ALS), better known as Lou Gehrig’s disease. The date of Medicare entitlement is based on the date of a diagnosis of ALS, or July 1, 2001, whichever is later. This provision affects both new and current beneficiaries.
