Medicare Coverage for Diabetes (2026)
About 33% of Medicare beneficiaries have diabetes or pre-diabetes. The 2026 Medicare benefit package — including the $35 insulin cap, expanded CGM coverage, and the new $2,000 Part D drug cap — is the most diabetes-friendly in Medicare's history. But the right plan choice still varies dramatically by your specific medications and providers.

- Insulin: $35/month cap on covered insulins under both Part D and Medicare Advantage drug benefits.
