Is Continuous Glucose Monitor (CGM) HSA/FSA Eligible?
Diagnostic device for managing diabetes.
How the rule applies
A continuous glucose monitor measures blood sugar for people managing diabetes. The sensors, transmitters and readers are diagnostic and treatment supplies, so they qualify.
What to keep for your records
Keep the pharmacy receipts, and the prescription if your plan wants to see it. Insurance may cover part of the cost, so submit only the amount you actually paid.
Watch out for
Do not claim anything your insurer already reimbursed. If you pay a copay at the pharmacy, the copay is the eligible amount.
Where to buy it HSA/FSA-eligible
Pay with your HSA or FSA card directly, or buy elsewhere and save the receipt to submit for reimbursement.
