If your plan covers it
Varies by plan
Self-pay via LillyDirect from $299/month (2.5 mg) to $449/month (7.5 mg and above), per zepbound.lilly.com on 10 September 2026; list price without the savings programme ~$1,086/month; $25/month copay card for eligible commercial insurance. The $449/month price for 7.5 mg and higher doses requires refilling within 45 days of the previous fill (otherwise the regular self-pay price is $499–$699), and the $299/month starting price applies to the KwikPen or vial, not the single-dose pen.

Insurance coverage reality
Medicare does NOT cover tirzepatide for weight loss alone. It DOES cover for heart disease prevention if you have obesity plus existing heart disease or high-risk factors. Commercial insurance coverage for tirzepatide varies by plan — it is generally newer to formularies than semaglutide, so ask your insurer directly what your plan requires.
How to get the lowest cost
Use LillyDirect vials
Tirzepatide vials via LillyDirect run $299–$449/mo depending on dose. Pens are full list price — always ask for vials.
Compare vial costs across doses
Starting dose (2.5 mg) is $299/month; 7.5 mg and above is $449/month.
Check your insurance
Coverage varies by plan. Compare your copay against the LillyDirect self-pay price before assuming insurance is cheaper.
Request prior authorization appeal
Many first denials are overturned on appeal with clinical documentation.
Consider semaglutide pill first
The Wegovy pill (self-pay $149–$299/mo) costs less than tirzepatide; the two drugs were tested in different trials.
