Continuous glucose monitor (Dexcom, Libre)
$100-$400/mo
Can You Write Off Continuous Glucose Monitor?
Short answer: Yes: a CGM and its sensors are diagnostic devices you can count as medical expenses.
Medical costs are an itemized deduction only for the amount above 7.5% of your AGI, and only if your itemized total beats the standard deduction ($16,100 single / $32,200 joint for 2026).
Records to keep: Keep receipts, statements (1098, 1098-T, 1099, W-2G), and a note of what each cost was for. Compare itemizing to the 2026 standard deduction before you claim.
