How often is it covered?
Medicare prescription drug coverage (Part D) may cover insulin and certain medical supplies used to inject insulin, like syringes, gauze, and alcohol swabs.
Your costs in Original Medicare
You pay 100% for insulin (unless used with an insulin pump, then you pay 20% of the Medicare-approved amount ) and 100% for syringes and needles, unless you have Part D.
