Yes, CareFirst can cover Zepbound again — with prior authorization, and only if your plan includes weight-loss drugs. CareFirst added Zepbound back to its Formulary 2 and Formulary 3 drug lists on October 1, 2026, at Tier 2 on most of them. Every Zepbound row still says coverage "is subject to your plan/benefits," so your employer's benefit choice decides it.
That's a real change. In July 2025, CareFirst dropped Zepbound from these same lists and pointed members to Wegovy and Saxenda instead. If you were told "CareFirst doesn't cover Zepbound" last year, that answer may be out of date. Here's what the lists say now, who qualifies, and what to send.
The quick answer by CareFirst plan type
Find your plan type first. Each one follows different rules.
| Your CareFirst plan | Does it cover Zepbound for weight loss? | What decides it |
|---|---|---|
| Employer plan, 51+ employees, on Formulary 3 | Maybe. Zepbound is listed at Tier 2 with PA since October 1, 2026 | Whether your employer included weight-loss drugs |
| Self-funded employer plan on Formulary 2 | Maybe. Listed at Tier 2 (3-tier list) or Tier 4 (4-tier list) with PA | Whether your employer included weight-loss drugs |
| Federal employee plan (FEP Blue) | Follows FEP's own national rules, not these lists | FEP Blue's formulary and exception process |
| CareFirst Community Health Plan Maryland (Medicaid) | Maryland Medicaid covers Zepbound for moderate-to-severe sleep apnea with obesity | State Medicaid criteria and your plan |
| CareFirst Medicare Advantage | Not through regular Part D for weight loss. Medicare's GLP-1 Bridge covers the Zepbound KwikPen | Medicare's Bridge rules |
Sources: CareFirst Formulary 3 and Formulary 2, 3-tier, both updated October 1, 2026; Maryland Medicaid Zepbound notice; Medicare.gov. Checked November 9, 2026.
The right next step depends on your plan type, whether weight-loss drugs are in your benefit, your BMI and health history, and whether you'd pay cash while you wait. The RX Index's Find My GLP-1 Path tool asks a few quick questions and shows the GLP-1 paths and providers that fit your goals, budget, insurance and situation.

What CareFirst's drug lists say about Zepbound now
CareFirst's Formulary 3 and Formulary 2 both list every Zepbound pen strength, 2.5 mg through 15 mg, with prior authorization (PA) and a quantity limit of one package every 28 days. Neither list adds a step-therapy rule for Zepbound. Both say coverage is subject to your plan and benefits.
Prior authorization is a permission slip. Your prescriber has to get CareFirst's OK before the pharmacy can bill your plan.
How Zepbound compares with other GLP-1s on CareFirst Formulary 3
| Drug | Tier on Formulary 3 | Notes on the list | What it tells you |
|---|---|---|---|
| Zepbound (pens, all strengths) | 2 (preferred brand) | PA, QL 1 package per 28 days; "coverage is subject to your plan/benefits" | Back on the list as of October 1, 2026 |
| Wegovy (pens) and Wegovy HD | 2 | PA, QL; same plan/benefits note | Same treatment as Zepbound |
| Wegovy pill and Foundayo pill | 2 | PA, QL; same plan/benefits note | Same treatment as Zepbound |
| Saxenda | 3 (non-preferred brand) | PA, QL; same plan/benefits note | Costs more than Zepbound on this list |
| Mounjaro | 2 | PA, QL 4 pens per 30 days | A type 2 diabetes drug |
| Ozempic | 2 | PA, QL | A type 2 diabetes drug |
Source: CareFirst Formulary 3, effective October 1, 2026, checked November 9, 2026.
Zepbound and Mounjaro are the same medicine, tirzepatide, made by Eli Lilly. They're approved for different jobs: Zepbound for weight management and sleep apnea, Mounjaro for type 2 diabetes. CareFirst has told prescribers that diabetes GLP-1s like Ozempic are covered only for type 2 diabetes, and that weight-loss coverage only applies when a plan includes that benefit (CareFirst GLP-1 coverage reminder). So asking for Mounjaro instead won't get around a missing weight-loss benefit.
On the 4-tier version of Formulary 2
Some self-funded employer plans use a 4-tier Formulary 2. On that list, Zepbound pens and Wegovy pens sit on Tier 4, still with PA and the same quantity limit. A higher tier usually means a higher copay or coinsurance, so check your cost in the CareFirst member portal (Formulary 2, 4-tier).
Why the answer changed in 2025 and again in 2026
CareFirst removed Zepbound, then put it back. Both changes were posted in CareFirst's quarterly formulary updates.
| Date | What CareFirst did | Lists named |
|---|---|---|
| July 1, 2025 | Removed Zepbound. CareFirst said "Wegovy and Saxenda will remain as alternative options" | F2, F3, F3 Choice, F2 CHART, F4 CHART |
| October 1, 2026 | Added Zepbound back | F2, F3, F2 CHART, F4 CHART |
Sources: CareFirst July 2025 formulary news; October 1, 2026 CareFirst commercial formulary updates. Checked November 9, 2026.
Two things to notice. First, "F3 Choice" was on the 2025 removal list but isn't named on the 2026 add list, so if your card says Formulary 3 Choice, confirm Zepbound with CareFirst before you start. Second, if you switched to Wegovy after July 2025, you don't have to switch back. Wegovy is still on the same lists. Talk with your prescriber about which fits you.
Does your CareFirst plan include weight-loss drugs? How to find out
Being on the drug list isn't the same as being covered. If your employer left weight-loss drugs out of your benefit, a PA can't make CareFirst pay. Check this before your prescriber spends time on paperwork:
- Log in at carefirst.com/myaccount. CareFirst says members can see their cost and drug rules under its drug pricing tool. Search "Zepbound."
- Call CareFirst Pharmacy Services at 800-241-3371, the number printed on the formulary, or the number on your ID card. Ask: "Does my plan include weight-loss drug coverage, and is Zepbound covered with prior authorization?"
- Ask HR if you're on a job-based plan. Employers choose whether to include weight-loss drugs. Formulary 2 is for self-funded plans, so your employer made that call directly.
Say you're 38, work for a hospital system in Maryland, and your CareFirst plan quoted Zepbound at full price last spring. That was likely the 2025 removal. Ask again now, by name, and ask whether your plan includes the weight-loss benefit.
Don't want to make those calls? Ro's insurance team will check whether your plan may cover Zepbound autoinjector pens and handle the paperwork, including PA. Ro says the coverage check is free. The Ro membership is a separate cost that insurance doesn't pay (Ro insurance).

What CareFirst asks for in a Zepbound prior authorization
CareFirst sends pharmacy prior authorization questions to CVS Caremark, its pharmacy benefit manager, and prescribers submit requests through the CareFirst Provider Portal (CareFirst pharmacy forms). Caremark's standard Zepbound criteria are below. CareFirst's own Zepbound form wasn't posted where we could open it, but its Wegovy form is faxed to CVS Caremark and asks the same questions as Caremark's criteria (CareFirst Wegovy PA form). Expect the same pattern for Zepbound, and ask CareFirst if your plan uses different rules.
To start Zepbound for weight loss, Caremark's standard criteria ask for:
- Age 18 or older, using it with a reduced-calorie diet and more physical activity
- At least 6 months in a comprehensive weight-management program with diet, activity and behavior change, plus follow-up visits, before starting the drug
- A starting BMI of 30 or higher, or 27 or higher with at least one weight-related condition, such as high blood pressure, type 2 diabetes or high cholesterol
- Documentation of your BMI and the condition
To keep Zepbound: at least 3 months at a steady maintenance dose, and at least 5% weight loss from your starting weight (or keeping that first 5% off).
For sleep apnea: moderate-to-severe obstructive sleep apnea with an apnea-hypopnea index (AHI) of 15 or more on a sleep study, plus a current BMI of 30 or higher. The 6-month program rule isn't part of the sleep apnea criteria.
How long approvals last: up to 8 months to start for weight loss (6 months for sleep apnea), then up to 12 months at a time.
Source: CVS Caremark Zepbound criteria 6192-C, checked November 9, 2026.
Your CareFirst Zepbound PA checklist
Quick self-check before your prescriber submits: Is your BMI 30 or higher, or 27 or higher with a weight-related condition? Have you been in a weight-management program for 6 months? If both are yes, gather:
| Item | Why CareFirst needs it |
|---|---|
| Confirmation your plan includes weight-loss drugs | Without the benefit, PA can't help |
| Starting height, weight and BMI | Required and must be documented |
| Your weight-related condition (if BMI 27–29.9) | Required at that BMI |
| 6 months of program records with follow-up visits | Visit notes, a program you joined, or nutrition counseling |
| Sleep study with AHI (if filing for sleep apnea) | Required for the sleep apnea path |
| For renewal: starting and current weights with dates | Shows the 5% loss |
The most common gap is the 6-month program record. Visit notes that mention diet and activity counseling count more than a note that just says "discussed weight."
If you've confirmed your BMI and you have the records, the next step is getting them in front of CareFirst correctly. Ro's insurance concierge verifies benefits, submits PA paperwork on your behalf and can file an appeal if coverage is denied. Ro says the whole process typically takes 1 to 3 weeks. It can't change CareFirst's criteria or add a missing benefit.

Does CareFirst cover the Zepbound vial or KwikPen?
Vials: no. Caremark's Zepbound criteria cover the pens and say vials are covered under Lilly's own direct program instead. If you buy vials for cash through LillyDirect, that's outside your CareFirst benefit.
KwikPen: CareFirst's lists show Zepbound in its 0.5 mL forms (written as "Zepbound inj 2.5/0.5" and so on), which match the single-dose pens. We didn't see a separate KwikPen row on the lists we read, though Caremark's criteria include quantity limits for the KwikPen. Ask CareFirst which device your plan will fill before your prescriber writes the prescription.
What Zepbound costs with CareFirst
If CareFirst approves Zepbound, you pay your plan's copay or coinsurance for its tier: Tier 2 on Formulary 3 and the 3-tier Formulary 2, Tier 4 on the 4-tier Formulary 2. Your exact number is in the CareFirst member portal.
Lilly's savings card can bring that down. Lilly says people with commercial insurance that covers Zepbound may pay as little as $25 for a one- or three-month supply of single-dose pens. A month means 28 days and up to four pens. Government plan members are excluded, and the card has monthly and annual limits (Lilly Zepbound cost information). Details are in our Zepbound savings card guide.
If CareFirst won't cover it, cash is the backup. On Ro's pricing page, the Zepbound KwikPen is cash-pay only: $299 a month at 2.5 mg, $399 at 5 mg, and $449 at 7.5 mg through 15 mg with the manufacturer offer. To keep the $449 price, Ro says you must complete each refill check-in within 45 days of your last delivery. Ro says its cash prices match LillyDirect, NovoCare and TrumpRx. The membership is extra: $39 the first month (refunded if you're not eligible), then $74 to $149 a month depending on plan length. The $74 rate is on a 12-month plan paid upfront (Ro pricing, checked November 9, 2026).
| Situation | What you'd likely pay |
|---|---|
| CareFirst covers Zepbound + you qualify for Lilly's card | As little as $25 per 1- or 3-month fill of single-dose pens, under the card's terms |
| CareFirst covers Zepbound, no card | Your plan's Tier 2 or Tier 4 copay or coinsurance |
| No coverage, cash KwikPen through Ro | $299–$449 a month for medication + Ro membership ($74–$149 a month after a $39 first month) |
| No coverage, other cash routes | Compare Zepbound at Costco and LillyDirect vial vs insurance |
Cash you pay while waiting usually doesn't count toward your CareFirst deductible, and it doesn't guarantee CareFirst will approve Zepbound later.

If CareFirst denies Zepbound
Read the letter for one thing: is it a denial or an exclusion? A denial means something in the criteria wasn't met or documented. An exclusion means your plan doesn't include weight-loss drugs.
If it's a denial: ask your prescriber what was missing. It's often the 6 months of program records, a dated BMI, or the weight-related condition. They can resubmit or appeal. See GLP-1 appeal levels explained.
If it's an exclusion: an appeal on medical grounds usually won't fix it. Ask HR whether the benefit can be added (how to ask your employer to cover a GLP-1), ask whether sleep apnea opens a separate path, or look at cash. Our guide to what to do if insurance doesn't cover weight-loss medication walks through each option.
CareFirst Medicaid, federal employee and Medicare plans
CareFirst Community Health Plan Maryland (Medicaid): Maryland Medicaid covers Zepbound for adults with obesity and moderate-to-severe sleep apnea. The state's criteria include a sleep study with AHI of 15 or more, a BMI of 30 or higher, height and weight from the last 90 days, a sleep specialist, lung specialist or other experienced provider, and no other GLP-1. Renewals run 6 months and stop if BMI falls under 30 (Maryland Medicaid Zepbound notice). The state tells providers to contact each Medicaid plan for its own criteria, so call CareFirst Community Health Plan Maryland to confirm. Ro says Medicaid patients aren't currently eligible for its program. More: does Medicaid cover Zepbound.
Federal employees (FEP Blue): CareFirst's pharmacy page lists a separate prior authorization line for FEP drugs, and FEP uses its own national formulary and rules, not the CareFirst lists above. See does FEHB cover Zepbound. Ro says FEHB members can use its insurance concierge.
CareFirst Medicare Advantage: Medicare's GLP-1 Bridge has covered the Zepbound KwikPen only since July 1, 2026, for a $50 copay per one-month supply. It doesn't cover single-dose Zepbound pens or vials. You must be 18 or older with a BMI of 35 or higher, or a lower BMI with certain conditions. People with type 2 diabetes, moderate-to-severe sleep apnea or fatty liver disease aren't eligible for the Bridge, but their regular Part D plan might cover a GLP-1 (Medicare.gov). Lilly's savings card excludes Medicare members. See does Medicare cover Zepbound.
Which path fits you
| If you… | Your best next step |
|---|---|
| Have a CareFirst employer plan and don't know if weight-loss drugs are included | Check the member portal, call Pharmacy Services, or use Ro's free coverage check |
| Were denied Zepbound in 2025 | Ask again. Zepbound was added back on October 1, 2026 |
| Have the benefit, a qualifying BMI and 6 months of program records | Have your prescriber submit the PA |
| Have the benefit but not 6 months of records yet | Start documenting now; ask about the sleep apnea path if it applies |
| Are on Formulary 3 Choice | Confirm Zepbound with CareFirst first |
| Have no weight-loss benefit | Ask HR, check the sleep apnea path, or compare cash |
| Have Maryland Medicaid through CareFirst | Ask about the sleep apnea criteria |
| Have CareFirst Medicare Advantage | Ask about the Bridge (KwikPen, $50 a month) |
Safety before you ask CareFirst
Do not use Zepbound if you or a family member has had medullary thyroid cancer (MTC), or if you have multiple endocrine neoplasia syndrome type 2 (MEN 2). Zepbound has a boxed warning about thyroid C-cell tumors. Tell your prescriber if you're pregnant or planning a pregnancy. Get care right away for severe stomach pain that won't go away (Zepbound prescribing information, revised August 2026).
What we actually verified
The RX Index is the independent GLP-1 decision resource that scores telehealth providers and treatment paths on clinical legitimacy, care quality, transparency, access, and cost, so readers can choose the path that fits their situation.
On November 9, 2026, we:
- Read CareFirst Formulary 3 and both versions of Formulary 2 (3-tier and 4-tier), all updated October 1, 2026, including every Zepbound, Wegovy, Foundayo, Saxenda, Mounjaro and Ozempic row.
- Read CareFirst's October 1, 2026 formulary update, its July 2025 Zepbound removal notice, its GLP-1 coverage reminder to prescribers, its pharmacy forms page and its Wegovy PA form.
- Read CVS Caremark's Zepbound criteria (6192-C), Maryland Medicaid's Zepbound notice, Medicare.gov's Bridge page, Lilly's Zepbound cost page, the Zepbound prescribing information, and Ro's pricing and insurance pages.
What we could not confirm: CareFirst Formulary 1 and individual (ACA) plan lists, CareFirst's own Zepbound PA form, your plan's benefit design, and your exact copay. Only CareFirst or your employer can tell you those. No web page, including this one, can tell you whether you'll be approved. CareFirst decides, based on what your prescriber sends.
Frequently asked questions
Does CareFirst cover Zepbound for weight loss in 2026?
It can. Since October 1, 2026, Zepbound is back on CareFirst Formulary 2 and Formulary 3 with prior authorization. Your plan still has to include weight-loss drugs, and you have to meet the criteria.
Did CareFirst stop covering Zepbound?
Yes, for a while. CareFirst removed Zepbound from several formularies on July 1, 2025, and pointed members to Wegovy and Saxenda. It added Zepbound back to Formularies 2 and 3 on October 1, 2026.
What tier is Zepbound on CareFirst?
Tier 2 (preferred brand) on Formulary 3 and the 3-tier Formulary 2. Tier 4 on the 4-tier Formulary 2. Your copay depends on your plan's tier costs.
What BMI does CareFirst require for Zepbound?
Under CVS Caremark's standard criteria, a starting BMI of 30 or higher, or 27 or higher with a weight-related condition like high blood pressure, type 2 diabetes or high cholesterol. You also need 6 months in a weight-management program first.
Does CareFirst cover Zepbound for sleep apnea?
Caremark's criteria include a sleep apnea path: moderate-to-severe sleep apnea with AHI of 15 or more, and a BMI of 30 or higher. Maryland Medicaid also covers Zepbound for sleep apnea under state criteria. Your commercial plan still decides whether the drug is in your benefit.
How long does a CareFirst Zepbound approval last?
Under Caremark's criteria, up to 8 months to start for weight loss, then up to 12 months per renewal if you've kept at least 5% of your weight off. For sleep apnea, it's 6 months to start, then 12.
Does CareFirst cover Zepbound vials?
No. Caremark's Zepbound criteria cover pens and say vials are covered through Lilly's own direct program. Vials bought for cash are outside your CareFirst benefit.
Can Ro help me get Zepbound covered by CareFirst?
Ro's insurance concierge checks coverage, submits PA paperwork and can appeal a denial for Zepbound autoinjector pens, Wegovy pens and Ozempic. It can't add a missing weight-loss benefit. Ro says Medicaid patients aren't currently eligible.
