Can you use an HSA on tirzepatide? Usually yes, when a licensed clinician prescribes it for a diagnosed condition. We compare how Eden, MEDVi, Ro, LillyDirect, and PlexusDx handle HSA at checkout, what 30–40% pre-tax savings looks like in real dollars, and where PlexusDx Tirzepatide Injection ($229–$309/mo), Tirzepatide Oral ($229–$509/mo), and GLP-Squared ($179–$325/mo) fit. PlexusDx accepts HSA card payment where your plan permits and does not directly bill.

FSA eligibility for semaglutide is governed by IRS Publication 502, not by individual provider marketing. We walk through the rule, the two payment paths (direct card at checkout vs reimbursement), how PlexusDx handles FSA-issued cards, and how compounded vs FDA-approved status affects substantiation.
