Does Medicare Cover Dialysis? (ESRD Entitlement Explained)

How ESRD Medicare entitlement works

Medicare covers kidney failure through its End-Stage Renal Disease (ESRD) program. You qualify if you need regular dialysis or a kidney transplant — regardless of your age. This makes ESRD one of only two conditions (the other being ALS) that grant Medicare eligibility before 65.

Coverage typically starts the first day of the 4th month of dialysis treatment (retroactive to the 3rd month in some situations). If you start home dialysis training or receive a pre-emptive transplant, coverage can begin immediately.

You must enroll even if you have private insurance — Medicare becomes the primary payer after a coordination period (typically 30 months after you become eligible), and your private plan may refuse dialysis coverage once Medicare is available.

• Part A (hospital): dialysis as an inpatient, hospital stays — no monthly premium for most people who paid Medicare taxes.
• Part B (medical): outpatient dialysis sessions, doctor visits, lab tests, durable equipment — requires the Part B premium (~$185/month in 2025, income-adjusted).
• Part D (drugs): covers many medications including phosphate binders and ESA injections in some circumstances.
• Medigap/MA plans: Medicare Advantage ESRD plans are now available in most states and often cover extra services and reduce out-of-pocket costs.

What dialysis costs after Medicare

Original Medicare pays 80% of approved amounts for dialysis. The remaining 20% coinsurance has no annual out-of-pocket cap under Parts A/B alone — which is why a Medigap policy or Medicare Advantage plan is strongly recommended for ESRD patients.

Medigap policies that cover the 20% coinsurance are the most common way ESRD patients control costs. Federal law now guarantees ESRD patients can buy Medigap in most situations (since 2016 for patients under 65).

The ESRD Medicare program is expensive overall — about $100,000 per patient per year for dialysis — but patient out-of-pocket costs with supplemental coverage are typically a few hundred dollars per month at most.

• Dialysis session cost to Medicare: ~$250-280 per session (composite rate + adjustments).
• Typical patient responsibility with Medigap: limited to deductibles.
• Kidney transplant: Part A covers the transplant hospitalization; anti-rejection drugs are covered under Part B for transplant recipients (lifelong coverage since 2000).
