Does Medicare Cover Insulin?

by John Krahnert | Published October 27, 2023 | Reviewed by Christian Worstell

Medicare Part D prescription drugs plans (PDPs) typically cover insulin. You may also consider enrolling in a Medicare Advantage plan that covers prescription drugs, which will likely cover insulin.

Generally, Medicare Part B (Medical Insurance) covers some of the services and supplies needed to manage diabetes, but not insulin.

What Medicare Plans Cover Insulin?

Certain diabetes drugs and supplies aren’t covered by Original Medicare. To get coverage for injectable insulin, you may consider joining a Medicare prescription drug plan (Part D) or a Medicare Advantage (Part C) plan that covers prescription drugs.

Medicare plans with drug coverage typically cover:

  • Injectable insulin not used with a pump

  • Inhaled insulin

  • Certain diabetic supplies used to inject or inhale insulin (syringes, needles, insulin pens, alcohol swabs, and gauze)

  • Anti-diabetic drugs used to maintain blood sugar

You can compare Part D plans available where you live and enroll in a Medicare prescription drug plan online when you visit

How Much Does Insulin Cost With Medicare Drug Plans?

Medicare Part D plans and Medicare Advantage are sold by private insurance companies. Plan availability and costs may vary.

Each Medicare drug plan has its own list of covered drugs and rules for coverage, known as a formulary.

Your actual drug coverage and costs will depend on:

  • The type of drugs you use

  • The Medicare Part D plan or Medicare Advantage plan you enroll in

  • Whether you go to a pharmacy in your plan’s network

  • Whether the drugs you use are on your plan’s formulary

  • Whether you get Extra Help paying your Part D costs

Be sure to speak with a licensed insurance agent to get details on:

  • Whether your Part D plan or Medicare Advantage plan covers your insulin supplies

  • How much these drugs will likely cost with your Part D coverage

  • What network of pharmacies and suppliers your plan uses

A Medigap Plan Can Help Cover Your Out-of-Pocket Diabetes Treatment Costs 

Even with Original Medicare's broad range of coverage, it leaves numerous out-of-pocket costs to recipients, including deductibles, copayments and coinsurance. 

A Medicare Supplement Insurance (Medigap) plan can help cover some of these costs.

For example, Medicare Part B covers medically necessary foot care, diabetes screenings and some diabetic test supplies for beneficiaries who have diabetes.

  • If you receive covered care, you will typically be responsible for paying the Part B deductible ($240 per year in 2024) and a 20% Medicare Part B coinsurance.

  • If you have a Medigap plan, it will help pay for the Part B coinsurance costs of your covered diabetes treatment.

You can have a Medigap plan and a Medicare Part D prescription drug plan at the same time.

Medigap plans and Medicare Advantage plans are not the same thing, however. You cannot have a Medicare Advantage plan and a Medigap plan at the same time.
