Enrolling is a choice. Before deciding, compare your current insurance costs, who pays first, your Part B premium, and how transplant medicines would be covered. These three paths can have very different consequences:
The Part B penalty depends on your specific enrollment history. Under Social Security's rules, months from a separate ESRD or disability entitlement before age 65 are not automatically carried into a later entitlement period; a penalty also resets at age 65. Ask Social Security to calculate your dates and premium. Compare ESRD enrollment paths and read Social Security's penalty rule.
When does Part B cover transplant medicines?
For someone who has Medicare only because of ESRD, Part B generally covers immunosuppressive (anti-rejection) medicines after a qualifying kidney transplant if Part A was in effect at the time of transplant, the transplant took place at a Medicare-certified facility, and Part B is active when the prescription is filled. Part B does not pay retroactively for medicines filled before Part B begins.
If ESRD-only Medicare ends 36 months after a successful transplant, a separate Part B Immunosuppressive Drug benefit (Part B-ID) may be available to people who meet its requirements and do not have disqualifying other health coverage. It covers eligible anti-rejection medicines only, not other medical care. Read Medicare's transplant drug guide and Part B-ID eligibility rules.
