QUICK ANSWER
Coverage Overview
Short answer: Express Scripts does not independently cover Wegovy—coverage is determined by your underlying health plan (employer, Cigna, TRICARE, etc.). On ESI's 2026 National Preferred Formulary, Wegovy and Zepbound single-dose pens are preferred; Zepbound vials, Zepbound KwikPens and Saxenda are excluded (if your plan covers weight-loss drugs at all), but whether weight-loss GLP-1s (a class of weight loss medications) are covered at all is up to your employer or plan.
Does Express Scripts cover Wegovy?
Express Scripts is a pharmacy benefit manager (PBM), not an insurance company. It processes prescriptions and manages formularies (drug lists), but your actual coverage is set by your health plan:
- Cigna plans: Express Scripts is owned by Cigna—see Cigna Wegovy coverage
- Employer plans: Coverage depends on whether your employer opted into GLP-1 benefits
- TRICARE: Express Scripts administers TRICARE pharmacy benefits—see TRICARE coverage
- Medicare Part D: Some Medicare plans use ESI; by federal law, basic Part D coverage excludes weight-loss drugs, but the Medicare GLP-1 Bridge covers Wegovy for $50 per monthly fill (with conditions)
Who this guide is for
People who see "Express Scripts" on their pharmacy card, use the Express Scripts website or app for prescriptions, or want to understand how their PBM affects Wegovy coverage.
PBM vs. Insurer: Why the Distinction Matters
Express Scripts doesn't make coverage decisions—your health plan does. ESI simply administers whatever pharmacy benefits your plan provides. This means:
- Two people with the same "Express Scripts" card can have different Wegovy coverage
- Your employer (not ESI) decides whether to include GLP-1 medications
- ESI's National Preferred Formulary is a default—plans can customize it
Good News: $200/Month Cap Available
Through the Evernorth Patient Assurance Program, some employer plans cap Wegovy costs: $200/month cap (only if your employer adds it).[1]

| Fact | Details |
|---|---|
| Ownership | Owned by Cigna since 2018, now part of Evernorth health services division[2] |
| What they do | Process pharmacy claims, manage formularies, negotiate drug prices, run mail-order pharmacy |
| Who uses them | Cigna plans, TRICARE, many employer-sponsored plans, some Medicare Part D plans |
| What they don't do | Make independent coverage decisions—they follow your plan's benefit design |
How to Know If You Have Express Scripts
- Check your pharmacy card: Look for "Express Scripts," "ESI," or the Evernorth logo
- Check your insurer: If you have Cigna, you likely have Express Scripts
- Log into express-scripts.com: If you can create an account or log in, you have ESI
- Call the pharmacy number on your ID card: Ask "Who is my pharmacy benefit manager?"
Express Scripts vs. Evernorth
In 2020, Cigna reorganized Express Scripts under a new brand called Evernorth. You may see either name—they're the same company. The $200/month GLP-1 cost cap is officially called the "Evernorth Patient Assurance Program."
Express Scripts serves different plans with different coverage.

Who Uses Express Scripts?
Express Scripts administers pharmacy benefits for several types of health plans. Your coverage for Wegovy depends on which plan you have—not on ESI itself.

Common Misconception
"I have Express Scripts, so my coverage is the same as other ESI members."
This is false. Two people with ESI cards can have completely different Wegovy coverage depending on their underlying plan. Always verify your specific plan's formulary and prior authorization (pre-approval from insurance) requirements.
Is Wegovy on the standard ESI formulary?
Check ESI formulary status →IS WEGOVY ON THE DRUG LIST?
ESI Formulary Status
Wegovy Is Preferred on the NPF—But Your Plan Decides Coverage
On the 2026 Express Scripts National Preferred Formulary (NPF), Wegovy and Zepbound single-dose pens are preferred; Zepbound vials, Zepbound KwikPens and Saxenda are excluded (if your plan covers weight-loss drugs at all). Whether weight-loss drugs are covered at all is up to the plan sponsor (usually your employer).[5] The NPF is the base formulary that many plans use.
Your specific plan is more likely to cover Wegovy if:
- Your employer opted into GLP-1 coverage: Large employers often customize formularies to include weight loss medications
- Your plan uses a non-standard formulary: Some plans don't use the NPF
- Your plan has the Evernorth cap: $200/month cap (only if your employer adds it)
- You have a qualifying condition: Wegovy for cardiovascular risk reduction may have different coverage
How to Check Your Specific Formulary
- Log into Express Scripts at express-scripts.com or the mobile app
- Search for "Wegovy" in the drug lookup tool
- Review the result:
- "Covered with prior authorization" = Your plan includes it
- "Not covered" or "Excluded" = Not on your formulary
- Call to confirm: Online tools can be outdated—call the number on your card
What If Wegovy Shows "Not Covered"?
You still have options:
- Request a formulary exception
- Ask your employer's HR to add GLP-1 coverage at next renewal
- Check if your plan covers Wegovy for cardiovascular risk (SELECT trial indication)
- Explore self-pay options including NovoCare
Some plans cap Wegovy costs at $200/month.
Learn about the Evernorth cost cap →COST CAP PROGRAM
$200/Month Evernorth Cap
Evernorth Patient Assurance Program
In May 2025, Evernorth (Express Scripts' parent company) launched a program that caps out-of-pocket costs for Wegovy and Zepbound at $200 per month for participating employer plans.[1]
Program Details
- $200/month maximum for Wegovy (and Zepbound)
- Compared with self-pay ($349/month ($399 for Wegovy HD 7.2 mg)), the cap can lower monthly cost on higher-cost plans
- Simplified prior authorization designed to speed up access
- Available only if your employer opts in—not automatic for all ESI plans
How to Check If Your Plan Has the $200 Cap
Questions to Ask
Call the Express Scripts number on your pharmacy card and ask:
- "Is my plan enrolled in the Evernorth Patient Assurance Program for GLP-1 medications?"
- "Does my plan have a $200/month cost cap for Wegovy?"
- "If not, what is my expected copay or coinsurance for Wegovy?"
You can also ask your HR department: "Has our company enrolled in the Evernorth $200/month GLP-1 cost cap program?"
If Your Plan Doesn't Have the $200 Cap
Your costs may still be manageable through:
- NovoCare savings offer: as little as $25 for commercially insured patients whose plan covers Wegovy
- Self-pay: $349/month ($399 for Wegovy HD 7.2 mg) through NovoCare (Wegovy is not on Novo Nordisk’s Patient Assistance Program list)

Prior Authorization for Wegovy

- Renewal requirements—typically must show 5% weight loss to continue coverage
ESI Decision Timelines
The legal deadline for an Express Scripts prior authorization depends on your plan type:
- Employer plans (federal claims rules): up to 15 days for a standard prior authorization, 72 hours if urgent
- Individual and small-group ACA plans (drug exception requests): 72 hours (24 hours if urgent)

Frequently Asked Questions
It depends on your underlying health plan, not ESI itself. Express Scripts is a pharmacy benefit manager (PBM) that administers pharmacy benefits for various insurers and employers. On the 2026 Express Scripts National Preferred Formulary, Wegovy and Zepbound single-dose pens are preferred; Zepbound vials, Zepbound KwikPens and Saxenda are excluded (if your plan covers weight-loss drugs at all), but whether your plan covers weight-loss drugs at all depends on your employer's benefit design.
Express Scripts is owned by Cigna. Cigna acquired Express Scripts in December 2018 for $67 billion. In 2020, Express Scripts was reorganized under a new brand called Evernorth, which is Cigna's health services division. If you have Cigna insurance, Express Scripts handles your pharmacy benefits.
Wegovy is preferred on the 2026 National Preferred Formulary (NPF)—but your plan decides whether weight-loss drugs are covered. On the NPF, Wegovy and Zepbound single-dose pens are preferred; Zepbound vials, Zepbound KwikPens and Saxenda are excluded (if your plan covers weight-loss drugs at all). Whether weight-loss drugs are covered at all is up to the plan sponsor. Check express-scripts.com or call the number on your pharmacy card to verify your specific plan's formulary.

Yes, with restrictions. Express Scripts administers pharmacy benefits for TRICARE. As of August 2025, Wegovy is covered with prior authorization for TRICARE Prime and TRICARE Select beneficiaries. However, coverage was discontinued for non-Prime/Select beneficiaries. See full TRICARE coverage guide →
If your Wegovy prior authorization is denied, you typically have 180 days to file an appeal. Request the denial in writing with the specific reason, then work with your doctor to submit a Letter of Medical Necessity.

No, not anymore. Anthem (now Elevance Health) left Express Scripts in 2019 after a contract dispute. Anthem now uses its own PBM, CarelonRx. If you have Anthem insurance, see our Anthem coverage guide instead.
