Medicare's 2027 Dialysis Rule: What Your 20% Share, Phosphate Binders, and Home Training Mean for You

If you or a loved one lives with kidney failure, Medicare just finalized changes that shape how dialysis is paid for — and what you'll owe — starting January 1, 2027. The CY 2027 End-Stage Renal Disease (ESRD) payment final rule (CMS-1846-F) was published in the Federal Register on October 30, 2026. Here's a plain-English look at what's changing, written for a national audience learning the basics.

The new 2027 base rate — and your 20% share

Medicare pays dialysis facilities a bundled amount per treatment. For 2027, that base rate is $297.52, up from $281.71 in 2026. Medicare Part B covers the service, and after you meet the Part B deductible, you pay 20% of the Medicare-approved amount. CMS estimates that, across all beneficiaries, coinsurance payments will rise about 2.7% in 2027 — roughly $50 million in total.

In practical terms: if you have Original Medicare without supplemental coverage, a higher base rate means a slightly higher share out of pocket per treatment. Many people manage this cost with a Medigap (Medicare Supplement) policy, Medicaid, employer coverage, or by enrolling in a Medicare Advantage plan that includes cost-sharing limits. Each path has trade-offs; more on that below.

The same $297.52 facility rate applies in 2027 for dialysis treating acute kidney injury (AKI), and CMS expects patients to pay less coinsurance at a dialysis facility than in a hospital outpatient department for that care.

Phosphate binders are now in the bundle

Since January 1, 2025, oral phosphate binders — commonly prescribed to control phosphorus levels in people with ESRD — have been paid through Medicare's dialysis payment system rather than through Part D. For 2027, CMS is finishing that transition by building binders into the base rate itself, adding $12.85 to account for them. Medicare.gov confirms Part B covers phosphate binders and other phosphate-lowering treatments for people with ESRD.

What this means for you:

• You generally won't fill phosphate binders at a retail pharmacy under Part D anymore; they're furnished as part of your dialysis care.
• The cost shows up as part of your dialysis coinsurance (that 20% share after the Part B deductible), not a separate pharmacy copay.
• If you've been using Part D for binders, ask your dialysis team how your prescription will transfer.

Home and self-dialysis training: a bigger payment and earlier start

CMS is raising the home and self-dialysis training add-on payment to $138.00 (from $95.60) in 2027. Just as importantly, the agency will allow training sessions during the onset period — the first 120 days of dialysis. Previously, timing rules could delay training.

Why that matters for patients: Medicare.gov confirms Part B covers home dialysis training for you and the person who helps you. A stronger payment and earlier window make it easier for facilities to offer home modalities (like home hemodialysis or peritoneal dialysis) to people who want them. Home dialysis isn't right for everyone, but if you're interested, this is a good year to raise the conversation with your care team.

How this fits into your broader 2027 Medicare picture

A few other national facts to keep in mind as you plan:

• Part D out-of-pocket cap: In 2027, no one pays more than $2,400 out of pocket for covered Part D drugs (up from $2,100 in 2026). The maximum deductible a Part D plan may charge in 2027 is $700. The Part D base beneficiary premium — a national figure used to calculate late-enrollment penalties — is $41.33; actual plan premiums are set plan by plan.
• COLA: Social Security announced a 3.6% cost-of-living adjustment effective January 2027.
• Not yet announced: The 2027 Part B standard premium and deductible, and the 2027 IRMAA income-related surcharges, haven't been released. CMS typically announces them in the fall.
• Annual Enrollment: October 15 – December 7, 2026, with coverage starting January 1, 2027.

Original Medicare vs. Medicare Advantage: a neutral look

People with ESRD can enroll in either Original Medicare (Parts A and B, often paired with a stand-alone Part D plan and sometimes a Medigap policy) or a Medicare Advantage plan. Both cover dialysis, but they work differently:

• Original Medicare generally lets you see any provider or dialysis facility that accepts Medicare, with that 20% coinsurance after the Part B deductible. There's no annual out-of-pocket cap unless you add a Medigap policy.
• Medicare Advantage plans have networks and prior-authorization rules, but include an annual out-of-pocket maximum for in-network Part A and B services and often bundle Part D.

Neither is "better" — it depends on your providers, your budget, and how you weigh choice versus cost predictability.

Special enrollment rights to know

If you have Medicaid or qualify for Extra Help (the Part D Low-Income Subsidy), you've had a monthly Special Enrollment Period since 2025 to move to Original Medicare with a stand-alone Part D plan — or to switch stand-alone Part D plans. Full-benefit dual-eligible individuals can also join an integrated D-SNP in any month. These rules give lower-income beneficiaries flexibility year-round.
