Tirzepatide cost with insurance in 2026: Zepbound, Mounjaro and what you'll really pay

Find your situation first. Each line points to the route that usually works best.

• Employer plan that covers Zepbound: get the prior authorization approved, then add Lilly's savings card. Prior authorization, or PA, is the plan's approval before it pays.
• Plan that excludes weight-loss drugs: check whether you qualify for Zepbound's sleep apnea use, then ask HR about coverage. If nothing works, Lilly's self-pay price is your fallback.
• Type 2 diabetes: Mounjaro is the covered name. Most plans pay for it after a PA, and the Mounjaro savings card can cut your share to about $25.
• Medicare: the GLP-1 Bridge is the main door for weight, at $50 a month for the Zepbound KwikPen if you meet its BMI rules.
• Medicaid: Mounjaro is covered for diabetes. Zepbound for weight depends on your state, and fewer states pay for it in 2026.
• Denied with no appeal left: LillyDirect sells Zepbound at the same self-pay price to insured and uninsured women.

Every way to pay for tirzepatide with insurance, explained

The table mixes three kinds of help. Lilly's own programs lower your copay, Medicare runs its own program, and online clinics handle the paperwork. Here is each one in turn.

Zepbound savings card: best when your plan covers Zepbound

This is Lilly's copay coupon for people with commercial insurance, meaning an employer or marketplace plan. Your plan must already cover Zepbound.

You can pay as little as $25 for a fill. The card pays up to $100 a month and up to $1,300 a year, so a high copay still leaves you something to pay.

Mounjaro savings card: best if you have type 2 diabetes

The Mounjaro card works the same way, with a bigger cap of $150 a month and $1,950 a year. Lilly's terms require a prescription for an approved use, which means type 2 diabetes.

A Mounjaro prescription written for weight alone will not qualify. Our Mounjaro savings page covers its fine print.

Medicare GLP-1 Bridge: best on Medicare

Since July 1, 2026, Medicare members can get some weight-loss drugs for $50 a month through a temporary program. For tirzepatide, it covers the Zepbound KwikPen only. The details are in the Medicare section below.

Ro: best for full-service insurance help

Ro's insurance team checks your coverage, files the prior authorization and handles appeals. Ro says a PA usually takes about one to two weeks.

Ro names the Zepbound autoinjector pen as one of only three drugs it bills to insurance. Mounjaro is not on that list.

The Ro Body membership is about $150 a month after a $40 first month. Prepaying a year brings it to about $75 a month, and insurance never pays the membership.

Ro offers Medicare members cash-pay options only and does not treat Medicaid members. Its weight program is not offered in Hawaii, Louisiana, Mississippi or Virginia. Ro holds 3.9 stars on Trustpilot from about 6,800 reviews. Details are in our Ro insurance review.

WeightWatchers Med+: best if you also want coaching

Med+ is the WeightWatchers clinic program. Its insurance coordinator makes the calls to your plan and manages prior authorizations and refills. Its site names both Zepbound and Mounjaro.

The membership is about $75 a month on a 12-month plan and about $85 on a 6-month plan, after a $25 first month. The medicine is billed separately, or as your copay if the plan covers it.

WeightWatchers holds 4.0 stars on Trustpilot from about 4,900 reviews, though that score covers the whole brand. More in our WeightWatchers insurance review.

Mochi Health: obesity-medicine doctors who file the PA

Mochi says it prescribes Zepbound and Mounjaro, and its prior authorization team handles the request with your plan. Once approved, you fill at a regular pharmacy for your plan's copay.

The membership is about $80 a month, with the first month free for new members in most states. A prepaid year brings it to about $50 a month, and HSA and FSA money is accepted.

Mochi also has a page for Medicare Bridge members, but its membership fee comes on top of the $50. It holds 4.5 stars on Trustpilot from about 18,800 reviews. See our Mochi Health insurance review.

LillyDirect self-pay: best if your plan says no

LillyDirect is Lilly's own online pharmacy. It sells Zepbound vials and KwikPens at one self-pay price, whether you have insurance or not.

The price follows the dose, from about $300 at the starting dose to about $450 at the higher ones. The full price ladder is in the cash section below.

Arbor: the compounded option, never covered

Arbor sells compounded tirzepatide, made by partner pharmacies, at one price for every dose. It is about $250 a month on a monthly plan, or about $150 a month if you pay a year upfront.

It is not Zepbound or Mounjaro, it is not FDA-approved, and no insurance plan pays for it. Arbor holds 4.5 stars on Trustpilot, but from only about 50 reviews.

Is tirzepatide covered by insurance? Zepbound vs Mounjaro: the diagnosis decides

Plans pay for a drug based on why it is prescribed. Zepbound and Mounjaro hold the same medicine but carry different FDA-approved uses.

• Zepbound, weight: for adults with a BMI of 30 or more, or 27 or more with a weight-related condition.
• Zepbound, sleep apnea: for moderate to severe obstructive sleep apnea in adults with obesity.
• Mounjaro, diabetes: to control blood sugar in adults with type 2 diabetes.
• Mounjaro, heart: since August 28, 2026, to lower the risk of heart attack, stroke and heart-related death in adults with type 2 diabetes at high heart risk.

Mounjaro prescribed for weight alone is off-label use, meaning outside its approved uses. Plans almost always deny it. If weight is the goal, Zepbound is the name to ask your plan about.

Our Mounjaro vs Zepbound comparison explains why the same molecule carries two names.

How to read your plan's drug list

Your plan's formulary is the list of drugs it agrees to pay for. Search it for Zepbound and Mounjaro by name, then read the codes beside each.

• PA: prior authorization is required before the plan pays.
• QL: a quantity limit caps how much the plan pays for each month.
• ST: step therapy means you must try another drug first.
• Tier: the tier sets whether you pay a copay, a flat amount per fill, or coinsurance, a share of the drug's price.
• Exclusions: some employer plans exclude all weight-loss drugs, even when the list shows Zepbound. Call the number on your card to ask.
• PBM: a pharmacy benefit manager, or PBM, runs the drug list for your insurer. Its name is often printed on your card.

KwikPen, single-dose pen or vial?

Zepbound comes in three forms. The single-dose pen holds one weekly shot, while the KwikPen holds four weekly doses in one pen. Vials hold one dose each and are drawn up with a syringe.

The form matters for money. Lilly's $25 offer for covered plans lists the single-dose pen, the Medicare Bridge pays only for the KwikPen, and self-pay covers vials and KwikPens. Check which form your plan lists.

How much is tirzepatide with insurance each month?

Covered does not mean one fixed price. Three parts of your plan decide what you pay at the counter.

• Copay: a flat amount for each fill. This is the simplest case, and the savings card works best here.
• Coinsurance: a percentage of the plan's price. Even 25% of a drug that lists above $1,000 a month comes to hundreds of dollars.
• Deductible: what you pay yourself each year before the plan starts sharing costs. Until you meet it, you may owe the plan's full price.

The list price is different from the self-pay price. The list price, called the wholesale price, is above $1,000 a month for both drugs. It is what coinsurance and deductibles are based on, while LillyDirect's self-pay price is far lower.

The January reset and copay accumulators

A high-deductible health plan, or HDHP, starts its deductible over every January. Your first fills of the year can cost hundreds of dollars even when Zepbound is covered.

The savings card still helps, but only up to its monthly cap. Some plans also leave the card's help out of your deductible. This rule is called a copay accumulator, and it stretches out the expensive months.

Ask your plan how it treats manufacturer coupons before January. Our tirzepatide cost breakdown shows the full price picture.

How to get the $25 Zepbound or Mounjaro savings card, and does it work on my dose?

Both cards come from Lilly and take a few minutes to set up online. Here is how they work in practice.

• Activate it: sign up on zepbound.lilly.com or mounjaro.lilly.com. Lilly's terms say the card must be activated before use.
• Show it: give the card numbers to your pharmacy with your insurance card, or to LillyDirect if you fill there.
• Your dose: the $25 floor does not change with the dose. What limits you is the cap, $100 a month for Zepbound and $150 for Mounjaro.
• Fills: each card allows up to 13 fills a year, and a fill can cover one, two or three months.
• End date: both cards say savings end on December 31, 2026. Lilly usually renews them, but check in January.

If your commercial plan does not cover Zepbound, Lilly offers a second deal. The single-dose pen can cost as little as $499 a month, while the KwikPen follows the self-pay prices. Mounjaro has a similar $499 offer for plans that do not cover it.

Neither card works with Medicare, Medicaid, TRICARE, VA or any other government drug plan. Activation steps and the full fine print are on our Zepbound savings page, and our tirzepatide savings guide compares every program.

Does Medicare cover tirzepatide in 2026?

Medicare's drug coverage, called Part D, cannot pay for drugs used only for weight loss. Tirzepatide gets in three other ways.

• Mounjaro for type 2 diabetes: Part D plans cover it, usually after a PA.
• Zepbound for sleep apnea: Part D plans can cover it for moderate to severe sleep apnea with obesity.
• The GLP-1 Bridge: a temporary program for weight, at $50 a month.

When Part D covers your drug, your 2026 out-of-pocket costs for all covered drugs stop at $2,100 for the year.

The Medicare GLP-1 Bridge: Zepbound for $50 a month

The Bridge started on July 1, 2026 and runs through December 31, 2027. It covers Wegovy, Foundayo and the Zepbound KwikPen. The single-dose Zepbound pen and Zepbound vials are not covered.

• Price: $50 a month, whatever your income. It does not count toward your Part D deductible or yearly cap.
• BMI of 35 or more: you qualify on BMI alone.
• BMI of 30 or more: you also need certain types of heart failure, blood pressure that is hard to control, or stage 3a kidney disease or worse.
• BMI of 27 or more: you also need prediabetes, or a past heart attack, stroke or blocked arteries in your legs or arms.
• Who is left out: people with type 2 diabetes, moderate to severe sleep apnea or fatty liver disease. Anyone whose Part D plan already pays for a GLP-1 also stays with the plan.
• Plans that qualify: a standalone Part D plan or a Medicare Advantage plan with drug coverage. Private fee-for-service plans, cost plans and PACE are left out.
• How to start: your prescriber sends the prescription, the pharmacy confirms you with your Medicare number, then your prescriber files an approval form. Refills need no new approval, even when the dose changes.

Mounjaro is not part of the Bridge. Neither savings card works with any Medicare plan.

Turning 65 while on Zepbound

Once you enroll in a Medicare drug plan, the $25 card stops, even if you keep a work plan. Plan the switch a few months ahead.

If you qualify for the Bridge, ask your prescriber to send a KwikPen prescription that starts with your Medicare coverage. If you have sleep apnea or diabetes, compare Part D plans on their tirzepatide coverage, not just their premium.

After 2027: what comes next is unclear

The Bridge was meant to lead into CMS's BALANCE model, which would bring weight-loss coverage into Part D. In April 2026, CMS postponed the Medicare part of that model and gave no new date.

Does Medicaid cover Zepbound or Mounjaro?

Mounjaro, yes, for type 2 diabetes in every state. States must cover drugs approved for diabetes, often after a PA.

Zepbound for weight depends on your state, because covering weight-loss drugs is optional for Medicaid. KFF counted 13 state programs covering GLP-1s for obesity in January 2026.

California, New Hampshire, Pennsylvania and South Carolina ended that coverage in January 2026. Massachusetts stopped covering weight-loss drugs on July 3, 2026, so the count has dropped again.

Sleep apnea works differently. Massachusetts kept paying for Zepbound for moderate to severe sleep apnea after dropping weight-loss coverage. Ask your Medicaid plan about Zepbound by name and by use.

Medicaid copays stay small, but the savings cards do not apply. Ro does not treat Medicaid members.

Which insurance plans cover Zepbound in 2026?

No insurer covers Zepbound the same way for everyone. The real decision usually sits with your employer and your PBM, not the logo on your card.

• CVS Caremark: it dropped Zepbound from its main lists in July 2025. Since October 1, 2026, it lists Zepbound again as a preferred option, alongside Wegovy, for employers that use its standard lists.
• Express Scripts and Optum Rx: weight-loss coverage is usually an add-on your employer chooses. Without it, Zepbound may still be covered for sleep apnea.
• Aetna, Cigna, UnitedHealthcare and Blue plans: each follows its PBM's list plus your employer's choices. Two people with the same insurer can get different answers.
• Marketplace plans: weight-loss drugs are not a required benefit, and few marketplace plans cover them.
• Federal employees: every FEHB plan must cover at least one GLP-1 for weight loss. For 2027, plans must also require a structured lifestyle program before and during treatment.
• TRICARE: Prime and Select cover weight-loss drugs with a PA. TRICARE For Life stopped covering them on August 31, 2025, but Mounjaro stays covered for diabetes.
• VA: Zepbound can be covered under set criteria, usually with a weight program such as MOVE!. Ask your VA prescriber.

Employers are the moving part. Some dropped weight-loss coverage for 2026, so check this year's plan documents, not last year's.

How to get tirzepatide covered: what prior authorization asks

Most plans that cover Zepbound ask for the same proof. Your prescriber sends it, and having it ready speeds things up.

• Your BMI, with a date: most plans follow the label, a BMI of 30 or more, or 27 or more with a weight-related condition.
• Weight-related conditions: high blood pressure, prediabetes, high cholesterol, sleep apnea or heart disease, each diagnosed in your chart.
• Sleep apnea route: a sleep study showing moderate to severe sleep apnea.
• Lifestyle records: notes from a diet, exercise or behavior program. Some plans set a minimum length.
• Step therapy: a few plans ask you to try another weight-loss drug first.
• Renewal: approvals last a set time. Renewal usually asks for proof of weight loss.

For Mounjaro, the PA asks for a type 2 diabetes diagnosis and lab results, and sometimes a trial of metformin first. Dose steps for Zepbound are in our Zepbound dosage guide.

Does menopause weight gain count?

Not on its own. Menopause is not an approved use for Zepbound, and insurers do not use it as a criterion. What counts is your BMI and the conditions in your chart.

Midlife often brings those conditions. Blood pressure, blood sugar and cholesterol tend to shift in the 40s and 50s, and sleep apnea becomes more common after menopause.

If you snore or wake up tired, a sleep study can open the sleep apnea route. Make sure each condition is diagnosed before the request goes out.

Hormone therapy treats menopause symptoms but is not a weight-loss drug, and plans review it separately. Our guide to perimenopause weight-loss medication explains how these drugs fit this stage of life.

My plan excludes weight-loss drugs: can Zepbound still be covered?

Sometimes. An exclusion blocks Zepbound for weight, but not always for its other approved use.

• Sleep apnea: with a diagnosis of moderate to severe sleep apnea and obesity, your prescriber can request Zepbound for that use. Many plans review it as a medical drug, not a weight-loss drug.
• Formulary exception: you can ask the plan to cover a drug it does not list. Marketplace and small-group plans must answer within 72 hours, or 24 hours when it is urgent.
• HR: some employers buy weight-loss coverage as an add-on, often called a rider. Ask HR whether it exists and whether it is up for review.
• Open enrollment: each fall, compare plans on Zepbound coverage, not just premiums.
• A spouse's plan: if your partner's employer covers weight-loss drugs, switching plans can be worth the math.

Zepbound or Mounjaro denied? How to appeal

Start with the reason on the letter. Missing proof can be fixed, while a plan exclusion needs the routes above.

• Ask for a peer-to-peer: your prescriber talks directly with the plan's reviewing doctor. It can settle a paperwork denial quickly.
• File an internal appeal: you have 180 days from the denial notice. For a drug you have not started, the plan must decide within 30 days.
• Urgent cases: the plan must decide as fast as your health requires, and within 4 business days at most.
• Send a strong letter: list your BMI history, each diagnosed condition and the programs you tried. Quote the plan's own criteria and show how you meet each one.
• Request an external review: if the plan says no again, you have 4 months to ask for an independent review. A standard decision comes within 45 days.

Your plan type decides who oversees the process. Self-funded employer plans, where the employer pays claims itself, fall under ERISA, the federal benefits law enforced by the Department of Labor.

Plans bought from an insurer, including marketplace plans, also answer to your state insurance department. No one publishes a reliable success rate for Zepbound appeals, so be wary of anyone who quotes one.

If insurance says no: the cheapest ways to get tirzepatide

A denial does not push you to the list price. LillyDirect's self-pay prices are the same whether you are insured or not.

• 2.5 mg starting dose: about $300 a month.
• 5 mg: about $400 a month.
• 7.5 mg to 15 mg: about $450 a month, if you refill within 45 days of your last delivery.
• Late refill: the regular price applies, about $500 at 7.5 mg and about $700 at 10 mg to 15 mg.

Each fill is a four-week supply. Since March 16, 2026, the KwikPen has also been sold at these self-pay prices in major retail pharmacies, not only through LillyDirect.

Lilly Cares, Lilly's free-medicine program for people with low incomes, includes Mounjaro but not Zepbound. Our Zepbound without insurance and Mounjaro without insurance pages rank every cash route, and tirzepatide without insurance adds the compounded options.

Compounded tirzepatide: cheaper, never covered

Compounded tirzepatide is made by a pharmacy from the same active ingredient. It is not Zepbound or Mounjaro, it is not FDA-approved, and no insurance plan pays for it.

At Arbor, it costs about $250 a month on a monthly plan, with one price at every dose. Paying a year upfront brings it to about $150 a month. Our compounded tirzepatide guide explains its legal status.

What a year of tirzepatide costs with insurance vs without

Monthly prices hide the real total. Each pen pack or self-pay fill lasts four weeks, so a year holds 13 fills. Here is a first year in common situations, at today's prices.

• Covered, copay plan, savings card: about $25 a fill, so about $325 a year.
• Medicare GLP-1 Bridge: $50 a fill, so about $650 a year.
• Covered, with Mochi's prepaid membership: about $590 for the year's membership plus about $325 in card copays, so about $910.
• Covered, with Ro's prepaid membership: about $890 for the membership plus about $325 in card copays, so about $1,210.
• Covered, high-deductible plan: say your deductible is $3,000 and the plan's price is about $1,000 a fill. The first three fills cost about $900 each after the card, then about $25. The year comes to about $2,950, more with a copay accumulator.
• Arbor compounded, year paid upfront: about $1,790, and more on a monthly plan.
• Denied, LillyDirect self-pay, staying at 5 mg: one fill at about $300, then about $400 a fill. The first year comes to about $5,090.
• Denied, LillyDirect self-pay, moving up to 7.5 mg or more: about $300, then $400, then about $450 a fill with on-time refills. The first year comes to about $5,640.
• No program at all: roughly $13,000 to $14,000 a year at list price.

The gap between the top and bottom lines is why an afternoon of paperwork is worth it.
