Does UPMC Health Plan Cover Phentermine (Adipex-P / Lomaira)?
The verdict
Conditional on most plans
UPMC Health Plan covers phentermine only when the specific plan includes a weight-loss or anti-obesity-medication benefit; plans with an AOM carve-out exclude it entirely, and standard Medicare Part D excludes it by statute. A Pennsylvania-specific development: PA Medicaid dropped adult weight-loss GLP-1 coverage in 2025, signaling a restrictive weight-loss climate in the state — though oral non-incretin agents like generic phentermine may be treated more favorably on the PDL than injectable GLP-1s. Phentermine is FDA-approved only for short-term use (~12 weeks) and is a DEA Schedule IV controlled substance. At $10–$40 for the generic, cash is often the fastest and cheapest path. UPMC cells are representative composites; verify on UPMC's member drug-search tool.

Medicare vs. commercial coverage
Whether UPMC Health Plan covers Phentermine (Adipex-P / Lomaira) depends heavily on which kind of plan you hold. They follow completely different rules — here's each one, side by side.
Medicare
Part D & Advantage plans
Medicare Part D statutorily excludes phentermine as a weight-loss agent. This applies to UPMC's Medicare Advantage and Part D plans. Phentermine is NOT included in the 2026 Medicare GLP-1 Bridge (July 1, 2026 – December 31, 2027), which covers only specified injectable weight-loss GLP-1s — Wegovy formulations, Foundayo, and the Zepbound KwikPen. Generic phentermine at $10–$40 cash is the operative route for Medicare beneficiaries; manufacturer copay cards are unavailable under federal anti-kickback rules.
Commercial / Employer
Group & marketplace plans
UPMC commercial and employer plans cover phentermine only when the employer group has elected a weight-loss or AOM benefit — many have not. Where covered, generic phentermine is typically the lowest-cost formulary option among anti-obesity agents and may be a required step before GLP-1 approval. Prior authorization where applied: BMI of 30 or higher, or 27 or higher with a qualifying comorbidity; DEA Schedule IV quantity limits; short-term (~12 weeks) approvals. ACA marketplace plans administered by UPMC are frequently more restrictive and often exclude AOM. Pennsylvania Medicaid (UPMC for You Medicaid): PA Medicaid dropped adult weight-loss GLP-1 coverage in 2025, reflecting a tightening state-level posture. Generic phentermine as a non-incretin oral agent may receive different treatment than injectable GLP-1s on the PA Medicaid PDL — but confirm the current PA HealthChoices PDL before assuming coverage. All figures are representative composites; verify on UPMC's drug-search tool.
The 4 boxes you must tick to get approved
Commercial plans that will consider Phentermine (Adipex-P / Lomaira) require prior authorization. Check off what applies to you to see how close you are — this is a guide, not a guarantee of approval.
Meet all 4 and you have a documented case for approval. Missing any one is the most common reason requests are denied.
Your cost, three ways
What Phentermine (Adipex-P / Lomaira) actually costs you swings enormously depending on how it's covered. Here's the realistic range.
Paying cash
Generic phentermine: approximately $40 retail per month, as low as $10 with a discount coupon (GoodRx / SingleCare). Brand Adipex-P and Lomaira are more expensive; the generic is the near-universal fill.
List price with no coverage — before any manufacturer savings card.
With coverage
Where phentermine is covered under a UPMC commercial or AOM-benefit plan, generic tier co-pays are typically $0–$15 per month. Confirm your specific tier on the UPMC member portal.
Typical monthly copay once prior authorization is approved.
No broad manufacturer copay card is available for phentermine. The Adipex-P copay program was discontinued February 1, 2024. Third-party discount cards (GoodRx, SingleCare) reduce the generic to $10–$40. Some states restrict coupons on DEA Schedule IV controlled substances; confirm Pennsylvania's current rules. All figures are estimates; verify with your plan and pharmacy.
Check YOUR exact coverage in 3 steps
General answers only get you so far. Here's how to confirm your own plan's decision in a few minutes.
- 1
Check your UPMC plan for anti-obesity-medication benefit coverage
Log into myUPMC or UPMC Health Plan's member portal with your member ID and search for phentermine in the drug-search tool. If no coverage appears, your plan likely has an AOM carve-out. Confirm with UPMC member services (1-888-876-2756 for commercial) or your HR department. Note that PA Medicaid cut adult weight-loss GLP-1 coverage in 2025 — check the current PA HealthChoices PDL if you have UPMC for You.
- 2
Talk to your prescriber about the Schedule IV and short-term-use requirements
Phentermine is a DEA Schedule IV controlled substance approved for approximately 12 weeks. Your prescriber must document your BMI and any qualifying comorbidities for a PA. Discuss whether phentermine is the right short-term option or whether a longer-term weight-management approach (GLP-1, lifestyle program) is preferable given Pennsylvania's tightening AOM coverage environment.
- 3
Use the cash route if excluded — the generic is $10–$40
If UPMC excludes phentermine, the cash path is straightforward: ask your prescriber for a phentermine prescription and present a GoodRx or SingleCare coupon at your pharmacy. The generic typically runs $10–$40 per month. Verify whether Pennsylvania permits coupon use for Schedule IV controlled substances before using one.
Options if UPMC Health Plan won't cover Phentermine (Adipex-P / Lomaira)
A denial isn't the end of the road. These are the paths people commonly explore next — discuss any of them with your prescriber.
Qsymia generic (phentermine/topiramate ER) — launched 2025
A generic phentermine/topiramate ER entered the market in 2025 (Teva), available for approximately $63 with a coupon. It combines phentermine with topiramate, offering longer-term use than standalone phentermine, but requires a REMS program and carries teratogenic risk from topiramate.
Contrave (naltrexone/bupropion) — CurAccess ~$99/month
Contrave is another oral anti-obesity agent, but it has no generic. The Currax CurAccess cash program offers it at approximately $99 per month — still significantly more than phentermine's generic.
Weight-loss GLP-1s (Wegovy, Zepbound) — if covered
GLP-1 weight-loss agents may offer greater long-term efficacy. However, PA Medicaid in Pennsylvania dropped adult GLP-1 coverage in 2025 and commercial plans frequently exclude them. Verify benefit eligibility before pursuing a GLP-1 PA at UPMC.
These options are listed for information only — your own clinician decides what is appropriate for you.
❓Frequently Asked Questions
UPMC Health Plan covers phentermine only if your plan includes a weight-loss or anti-obesity-medication benefit. Employer-sponsored plans frequently carve out AOM coverage, and Medicare Part D excludes it by statute. Pennsylvania Medicaid dropped adult weight-loss GLP-1 coverage in 2025, making the state's AOM landscape more restrictive. Because the generic costs just $10–$40 cash, most patients find cash payment faster than a coverage appeal. Verify on UPMC's member drug-search tool.
Pennsylvania Medicaid dropped adult weight-loss GLP-1 coverage in 2025. Phentermine is a non-incretin oral agent and may be treated differently on the PA HealthChoices preferred drug list — some state Medicaid programs retain cheap oral AOM agents even after cutting GLP-1s. However, coverage is not guaranteed. Check the current PA HealthChoices PDL or contact UPMC for You member services directly to confirm phentermine's current formulary status.
No. Medicare Part D statutorily excludes phentermine and all other agents prescribed for weight loss. This applies to all UPMC Medicare Advantage and Part D plans. Phentermine is not included in the 2026 Medicare GLP-1 Bridge. For Medicare beneficiaries enrolled in UPMC Medicare Advantage, the generic at $10–$40 cash is the only realistic route; manufacturer copay cards are prohibited under federal rules.
Yes — some UPMC plans apply step-therapy requiring a documented phentermine or Contrave trial before approving a weight-loss GLP-1 like Wegovy or Zepbound. However, given that Pennsylvania Medicaid dropped adult GLP-1 coverage in 2025 and commercial carve-outs are common, GLP-1 approval pathways are narrow in Pennsylvania. Confirm step-therapy requirements with UPMC member services and your prescriber before beginning a phentermine course for this purpose.
Generic phentermine costs approximately $40 per month at retail, and as low as $10 per month with a GoodRx or SingleCare discount coupon at most Pennsylvania pharmacies. No broad manufacturer copay program exists — the Adipex-P program was discontinued in February 2024. Some states restrict coupons on DEA Schedule IV controlled substances; verify Pennsylvania's current rules with your pharmacist before presenting a coupon.
