Horizon NJ Health, which administers NJ FamilyCare Medicaid coverage, does not cover Wegovy for weight loss in adults 21 and older. There are two exceptions: members under 21 can get it approved as an anti-obesity medication, and adults 18 and older can get it approved to reduce cardiovascular risk if they have established heart disease. Both routes require prior authorization and a medical necessity review.
The Two Situations Where Coverage Is Possible
Members Under 21
For members younger than 21, Wegovy may be approved as an anti-obesity medication. This route exists because federal Medicaid law requires states to provide Early and Periodic Screening, Diagnostic, and Treatment services for children and young adults, which can include medically necessary weight management drugs that are otherwise excluded for adults.
The prescribing provider has to document weight-related health problems, risk factors, or complications. The member also has to be participating in a comprehensive weight loss treatment plan (nutritional counseling, an exercise regimen, or a calorie-restricted diet) and commit to continuing it while on the medication.
Adults With Established Cardiovascular Disease
In March 2024, the FDA approved Wegovy for a second use: reducing the risk of major cardiovascular events (heart attack, stroke, or cardiovascular death) in adults with established cardiovascular disease who are also obese or overweight. Horizon NJ Health covers Wegovy for this purpose.
The requirements are stricter than for the pediatric route. The prescription has to be written by, or in consultation with, a cardiologist or vascular specialist. The member has to be maintained on appropriate cardiovascular medications. The target dose has to fall within the manufacturer’s recommended range of 2.4 mg weekly, which is the dose shown in clinical trials to reduce major cardiovascular events. If the member has type 1 diabetes, the provider has to confirm Wegovy will be used with caution.
How to Get Prior Authorization
Approval is never automatic. The provider completes Horizon NJ Health’s “Anti-Obesity Medications (AOMs) for Members Younger than 21 Years of Age and Wegovy for Established Cardiovascular Disease — Medical Necessity Request” form and faxes it to 888-567-0681. The form collects the member’s height, weight, diagnosis, and treatment history.
Providers also have to confirm several safety items on the form:
- No personal or family history of medullary thyroid carcinoma or Multiple Endocrine Neoplasia syndrome type 2, and no prior serious allergic reaction to semaglutide.
- The member is not taking another GLP-1 receptor agonist (Ozempic, Mounjaro, Trulicity, or Victoza) or another weight loss product at the same time.
- For obesity requests, the member is actively following a comprehensive weight loss plan. For cardiovascular requests, the member has received individualized healthy lifestyle counseling.
Renewal requests carry extra requirements on the cardiovascular side. The provider has to document whether the member is on the standard 2.4 mg weekly dose (and explain any alternative dosing), confirm the medication has not worsened the member’s cardiovascular health, and verify the member is still on appropriate heart medications.
What You Pay if Wegovy Is Approved
Copays depend on the specific NJ FamilyCare plan. Members in Plans A, ABP, and B pay nothing for prescriptions. Plan C members pay $1 for generics and $5 for brand-name drugs. Plan D members pay $5 for any prescription and $10 if the supply exceeds 30 days. Wegovy is a brand-name medication, so Plan C or D members pay the brand-name copay.
If Your Request Is Denied
When Horizon NJ Health denies a prior authorization, the member can file an internal appeal. Standard appeals must be decided within 30 calendar days. If waiting 30 days could cause serious harm, or the member is hospitalized, the member or provider can request an expedited appeal, which must be decided within 72 hours. Expedited appeals go through 1-800-682-9094, extension 89606.
Why Adult Weight Loss Coverage Is Off the Table
The restriction is not specific to Horizon NJ Health. NJ FamilyCare currently covers anti-obesity medications only for FDA-approved uses other than weight loss (Wegovy for cardiovascular disease, Zepbound for sleep apnea) plus pediatric cases under federal EPSDT rules. A proposed federal rule that would have required state Medicaid programs to cover weight loss medications was not finalized in April 2025, leaving the decision to individual states. New Jersey Assembly Bill 3369, introduced in the 2026 session, would require Medicaid and NJ FamilyCare to cover anti-obesity medications for enrollees with obesity or an obesity-related condition, but its coverage provisions depend on federal waiver or state plan approval, and it remains pending.
Wegovy and Ozempic Are Handled Differently
Wegovy and Ozempic both contain semaglutide, but the plan treats them as separate products. Ozempic is approved for type 2 diabetes and runs through the standard diabetes formulary. It appears on the New Jersey Medicaid preferred drug list with prior authorization and quantity limit requirements. Wegovy is classified as an anti-obesity medication and is subject to the age and indication rules above.
You cannot use an Ozempic prescription as a workaround to get semaglutide for weight loss. The medical necessity form treats Ozempic as a co-administration concern: providers have to disclose whether the member is also taking Ozempic or any other GLP-1 receptor agonist, and simultaneous use is generally not permitted.
Make Sure You Actually Have Horizon NJ Health
Horizon NJ Health and Horizon Blue Cross Blue Shield of New Jersey are related but distinct. Horizon NJ Health serves NJ FamilyCare Medicaid members (1-800-637-2997, horizonnjhealth.com). Horizon BCBSNJ sells commercial, employer-sponsored, and Medicare plans (1-800-224-1234, horizonblue.com), and its commercial plans cover Wegovy more broadly, including a standard weight management indication for adults and patients 12 and older. If your coverage runs through NJ FamilyCare, the Medicaid rules in this article apply; if it runs through an employer or a commercial policy, check your plan documents instead.
