The immunosuppressive drug benefit premium in 2026
Medicare eligibility based on end-stage renal disease normally ends 36 months after a successful kidney transplant. The Part B-ID benefit exists so that the anti-rejection drugs keep being covered after that point — and nothing else does.
2026 Part B-ID standard monthly premium
$121.60
Against the full Part B standard premium of $202.90. It is a narrower benefit at a lower price, not a discount on the same coverage.

What it covers, and what it does not
Part B-ID pays for immunosuppressive drugs and nothing else. It is not a substitute for Part B: doctor visits, outpatient care, lab work, durable equipment and every other Part B service are outside it. Someone enrolled in Part B-ID does not have Medicare in the ordinary sense — they have drug coverage that keeps a transplant working.
The benefit is separately premium-rated, and the premium is not withheld from a Social Security payment the way standard Part B is for most people. The ledger pages on this site deduct the standard Part B premium, not this one.
| Part B-ID | Standard Part B | |
|---|---|---|
| Standard monthly premium | $121.60 | $202.90 |
| Annual deductible | — | $283 |
| Scope | Immunosuppressive drugs | All Part B services |
The ten-cent gap is real
Part B immunosuppressive-drug IRMAA amounts run about 10 cents below the full Part B amounts at each tier ($81.10 vs $81.20). That is a real artifact of the statute's application, not a transcription error, and must not be "corrected".
It looks like a transcription error and it is not: the income-related amounts for Part B-ID are computed against the Part B-ID actuarial rate rather than the full Part B one, so the two ladders run parallel but never quite coincide. An ingest that “corrected” the gap would be introducing an error, not removing one. This site preserves it and says so.
