Short answer up top, then the exact rule. Here's what Original Medicare does and doesn't cover for medical nutrition therapy in 2026 — and where a Medicare Advantage plan can fill the gap.
Quick answer: Yes — free, if you qualify. Part B covers medical nutrition therapy (MNT) from a registered dietitian if you have diabetes or kidney disease (or a kidney transplant in the last 36 months) and your doctor refers you. You pay $0 when the provider accepts assignment.
Medicare Advantage plans cover MNT for diabetes and kidney disease the same way — $0 when you meet the criteria and stay in-network. Some plans go further with broader nutrition or wellness counseling; check your plan's benefit details.
People with diabetes or kidney disease (or a recent kidney transplant) who have a doctor's referral. If you have diabetes, ask your provider about pairing MNT with diabetes self-management training — a related but separately-billed benefit.

See 2026 Medicare Costs →Yes, if you have diabetes or kidney disease (or a kidney transplant in the last 36 months) and a doctor refers you. Medical nutrition therapy from a registered dietitian is then $0 — 3 hours the first year and 2 hours each year after.
Medicare's medical nutrition therapy benefit is specifically for diabetes and kidney disease. Without one of those, MNT isn't covered under Part B, though some Medicare Advantage plans offer broader nutrition counseling.
