Medicare only covers insulin if it’s medically necessary and you use an external insulin pump to administer the insulin. You pay 20% of the Medicare -approved amount , and the Part B deductible applies.
Note: Medicare prescription drug coverage (Part D) may cover insulin, certain medical supplies used to inject insulin (like syringes), and some oral diabetic drugs. Check with your plan for more information.
You may need to use specific suppliers for some types of diabetic testing supplies. Visit Medicare.gov/supplierdirectory to find a list of suppliers for your area.
