An employer-offered account that lets you set aside pre-tax money for eligible health costs, which can include prescription GLP-1s and sometimes telehealth fees. The catch is the "use it or lose it" rule (funds usually don't roll over year to year) so timing your spending matters. Keep receipts, since membership-style telehealth fees aren't always reimbursable without documentation.
