Does Medicare Part B Cover Insulin? 
Medicare Part B does not cover the insulin prescription itself - that can be covered by prescription drug coverage under a stand-alone Part D plan . An exception to this to have insulin covered under Part B is when insulin is administered via a medically necessary insulin pump - under this scenario , an external insulin pump and the insulin may be covered as durable medical equipment . Part B can cover certain diabetic test supplies as durable medical equipment -LRB- DMEs -RRB- such as glucose testing monitors , test strips , lancet devices , and lancets . Medicare would pay for 80 % of Part B covered expenses - you would be responsible for the other 20 % . A Medigap plan can cover the other 20 % of expenses for you . If you 're looking for a Medigap plan or are interested in seeing if a lower rate is available compared to your existing plan -LRB- Medigap plans are standardized -RRB- , please feel free to contact me for help . Thanks very much .
