Details
All forms of insulin - vials, pens, cartridges, and inhaled insulin - are HSA-eligible without requiring a prescription. Insulin has always been eligible for HSA funds, and the CARES Act reinforced that no prescription is needed. Insulin pumps and continuous glucose monitors are also eligible.
