If you are an Aetna member in Maine wondering whether your plan may cover weight loss treatment. Including GLP-1 medications like Wegovy or Zepbound. This guide explains what Aetna typically offers, how CVS/Caremark (Aetna’s pharmacy benefit manager) structures its weight loss formulary, and what Maine law does and does not require insurers to cover.
Coverage varies widely by plan. Always verify your specific benefits before booking an appointment or filling a prescription.
Klarity Health connects Maine residents with licensed weight loss providers for telehealth consultations. Our network of 2,000+ providers can evaluate your eligibility for GLP-1 medications and work with your Aetna plan on prior authorizations.

Maine’s primary insurance parity law. Me. Rev. Stat. Ann. tit. 24-A, § 2749-A. Requires commercial fully-insured plans to cover mental health and substance use disorder (MH/SUD) conditions at parity with medical-surgical benefits. Weight loss and obesity treatment are not classified as MH/SUD conditions under § 2749-A, so this statute does not require Aetna to cover weight loss medications.
Coverage for weight loss treatment in Maine is governed instead by:
If your employer offers a self-funded ERISA plan through Aetna, the plan is governed by federal ERISA rules, not Maine insurance law. Self-funded plans set their own pharmacy benefit terms.
Maine requires electronic prescribing (EPCS) for all controlled substances in Schedules II through V under Me. Rev. Stat. Ann. tit. 32, § 13796 et seq. Whether this applies to a specific weight loss medication depends on its federal controlled substance schedule:
| Medication | Type | Federal Schedule | Maine EPCS |
|---|---|---|---|
| Wegovy (semaglutide 2.4 mg) | GLP-1 agonist | Non-scheduled | Not applicable |
| Zepbound (tirzepatide) | GLP-1/GIP dual agonist | Non-scheduled | Not applicable |
| Saxenda (liraglutide 3 mg) | GLP-1 agonist | Non-scheduled | Not applicable |
| Contrave (naltrexone/bupropion) | Combination | Non-scheduled | Not applicable |
| Orlistat / Xenical | Lipase inhibitor | Non-scheduled | Not applicable |
| Phentermine (generic) | Stimulant / appetite suppressant | Schedule IV | EPCS REQUIRED |
| Qsymia (phentermine/topiramate) | Combination + REMS | Schedule IV | EPCS REQUIRED |
Because GLP-1 medications (Wegovy, Zepbound, Saxenda) and Contrave are non-scheduled, Maine’s EPCS requirement does not apply to them. Phentermine and Qsymia are Schedule IV controlled substances. Prescribers in Maine must use an electronic prescribing system that meets DEA 21 CFR Part 1311 requirements to issue these prescriptions.
Qsymia also requires enrollment in the Qsymia REMS program due to teratogenicity risk, regardless of EPCS status.
Aetna uses CVS/Caremark as its pharmacy benefit manager. The CVS/Caremark weight loss formulary structures coverage for obesity medications as follows. Note that specific tier placement and prior authorization (PA) criteria may vary by your Aetna plan:
| Medication | Typical Tier | PA Required | Key Criteria | ME EPCS |
|---|---|---|---|---|
| Wegovy (semaglutide) | Tier 4. 5 (Specialty) | Yes | BMI ≥30, or ≥27 + comorbidity | Not applicable |
| Zepbound (tirzepatide) ★ Reinstated Oct 1, 2026 | Tier 4. 5 (Specialty) | Yes | BMI ≥30, or ≥27 + comorbidity; was removed Jul 1, 2025 | Not applicable |
| Saxenda (liraglutide) | Tier 4 (Specialty) | Yes | BMI criteria; prior GLP-1 trial may be required | Not applicable |
| Contrave (naltrexone/bupropion) | Tier 3. 4 | Yes | BMI criteria; behavioral counseling concurrent | Not applicable |
| Phentermine (generic) | Tier 2. 3 | Yes (many plans) | Short-term use (≤12 weeks); BMI criteria | EPCS REQUIRED (Schedule IV) |
| Qsymia (phentermine/topiramate) | Tier 3. 4 | Yes + REMS | BMI criteria; REMS enrollment required; Schedule IV | EPCS REQUIRED (Schedule IV) |
CVS/Caremark removed Zepbound (tirzepatide) from its commercial formulary effective July 1, 2025, favoring Wegovy (semaglutide) as the preferred GLP-1 for weight management. However, CVS/Caremark reinstated Zepbound on its commercial formulary effective October 1, 2026. Aetna members with CVS/Caremark pharmacy benefits may now be eligible for Zepbound coverage. Subject to prior authorization and plan-specific BMI criteria. Starting on that date.
This is a key differentiator compared to Cigna members, whose pharmacy benefits are managed by Express Scripts (ESI). ESI never removed Zepbound from its formulary. Cigna/ESI members have had continuous Zepbound access at Tier 3. 4. Aetna members who were switched from Zepbound to Wegovy during the CVS/Caremark removal period may wish to discuss reinitiating Zepbound with their provider after October 1, 2026.
GLP-1 medications for weight loss typically require prior authorization (PA) through Aetna/CVS/Caremark. Common PA criteria may include:
PA decisions under Aetna’s standard process are typically rendered within 15 calendar days for non-urgent requests. Urgent PA requests (where a delay would seriously jeopardize health) must be decided within 72 hours.
Aetna and CVS/Caremark may apply step therapy protocols requiring a trial of a lower-tier or preferred weight loss medication before approving a non-preferred agent. Maine does not have a specific step therapy exception statute for weight loss medications (unlike some other states). However, members may:
Under the Affordable Care Act, all non-grandfathered commercial health plans. Including Aetna plans in Maine. Must cover the following at no cost-sharing when delivered by an in-network provider:
These preventive benefits cover counseling and behavioral interventions, not prescription medications. Medication coverage depends on your Aetna plan’s pharmacy benefit design.
Before starting weight loss treatment, take these steps to confirm your benefits:
If Aetna denies your prior authorization request for a weight loss medication, you have several options:
Note: Maine § 2749-A parity rights apply to mental health and substance use disorder claims. They do not apply to weight loss coverage disputes. Weight loss appeals proceed under general insurance contract law and ACA appeal rights.

Wegovy (semaglutide 2.4 mg) may be covered under Aetna plans in Maine that include pharmacy benefits for weight loss medications. Coverage typically requires prior authorization with documented BMI ≥30 or ≥27 with a qualifying comorbidity. Coverage varies by plan. Verify with Aetna at 1-800-872-3862.
CVS/Caremark removed Zepbound from its commercial formulary on July 1, 2025, but reinstated it effective October 1, 2026. Aetna members with CVS/Caremark pharmacy benefits may be eligible for Zepbound coverage starting October 1, 2026, subject to prior authorization and plan-specific criteria. Contact CVS/Caremark at 1-800-552-8159 to confirm your plan’s coverage.
No. Maine’s mental health parity law (§ 2749-A) applies specifically to mental health and substance use disorder conditions. There is no Maine state law requiring commercial insurers to cover weight loss medications. Coverage depends on your plan’s pharmacy benefit design and federal ACA requirements.
Yes. All FDA-approved weight loss prescription medications require a valid prescription from a licensed provider. GLP-1 medications such as Wegovy and Zepbound do not require an EPCS (electronic prescription for controlled substances) because they are non-scheduled. Phentermine and Qsymia are Schedule IV controlled substances and require EPCS in Maine.
Many Aetna plans cover telehealth services for medical consultations, including obesity and weight management evaluations. Telehealth coverage specifics depend on your plan. Klarity Health providers offer telehealth weight loss consultations. Contact Aetna at 1-800-872-3862 to confirm your telehealth benefits before scheduling.
You have the right to appeal. Request a peer-to-peer review between your provider and Aetna’s medical reviewer, then file a formal internal appeal with supporting clinical documentation.
