Best Medicare for diabetics in 2026.
If you have diabetes, the right Medicare plan can mean the difference between $0 insulin and $300/month out-of-pocket. The $35 insulin cap and $2,000 Part D out-of-pocket cap make 2026 the best year ever for diabetic Medicare members — but plan choice still matters.
Key facts to know
Since 2023, Medicare caps insulin copays at $35/month per insulin product. This applies to all Medicare Advantage and Part D plans. No more shopping for the cheapest insulin formulary — every plan must offer this cap.
In 2026, your total out-of-pocket cost for prescription drugs is capped at $2,000/year (down from $3,300 in 2024). For diabetics taking expensive non-insulin meds (Ozempic, Mounjaro, Jardiance), this is a game-changer. Once you hit $2,000, all covered drugs are $0 for the rest of the year.
Medicare covers CGMs (Dexcom G7, FreeStyle Libre 3) for both Type 1 and Type 2 diabetics on insulin or with frequent hypoglycemia. Coverage is through Part B as durable medical equipment (DME) — typically 80% covered after Part B deductible. Some Medicare Advantage plans cover CGMs at $0 or low copay.
Test strips and lancets are covered through Part B as DME (80% Medicare, 20% you). Standard meters are usually free from manufacturers. Diabetic shoes (1 pair/year) and diabetic education are also Part B covered.
These are typically Tier 3 or Tier 4 on Part D plans, with copays of $40-$120/month. The $2,000 annual cap means after a few months you hit the cap and pay $0. Choose a Part D plan that puts your specific drug at the lowest tier.
Best fit
For most diabetics: Original Medicare + Medigap Plan G + a Part D plan with your specific diabetic drugs at low tier. The Medigap plan eliminates the 20% Part B copay on test strips, CGMs, and diabetic supplies. Total cost typically $200-$300/month all-in.
If budget is tight, a $0-premium Medicare Advantage plan with a strong diabetes care management program (UnitedHealthcare, Humana, Aetna often have these) can be a good fit — but watch for high copays on the more expensive non-insulin drugs.
