Understand the cost of medical weight-loss care.

What drives the cost of weight-care?

Out-of-pocket costs depend on several factors that interact in surprising ways:

• Your insurance plan and formulary. Many commercial plans cover GLP-1 medications for type 2 diabetes but exclude them for weight loss. Some employer plans add a weight-loss carve-out.
• Prior authorization rules. Most insurers require documentation of BMI, comorbidities, and prior lifestyle attempts before approving GLP-1 weight-loss coverage.
• Provider type. A telehealth weight-care clinic, primary-care physician, and obesity-medicine specialist may bill differently and prescribe different medications.
• Brand vs. compounded versions. Brand-name semaglutide and tirzepatide carry list prices around $1,000–$1,400 per month before discounts. Compounded versions sold through some telehealth clinics are typically much less but come with quality and safety considerations.
• Manufacturer savings programs. Eli Lilly and Novo Nordisk run patient-assistance programs with eligibility limits. These can dramatically reduce monthly costs for some patients.

Questions to ask your insurance plan

1. Is weight-loss medication covered under my plan? If yes, which medications are on the formulary?
2. Is a prior authorization required, and what documentation do you need from my provider?
3. What is my expected out-of-pocket cost after deductible and copay?
4. Are there step-therapy requirements (do I need to try cheaper medications first)?
5. Does my plan cover obesity-focused office visits and nutrition counseling separately?
6. Are there in-network telehealth weight-care providers?

Prior authorization, in plain English

Prior authorization (PA) is the insurer's way of confirming that a prescribed treatment meets their clinical criteria before they pay for it. For GLP-1 weight-loss medications, a typical PA asks your provider for:

• Documented BMI ≥ 30, or BMI ≥ 27 with at least one weight-related comorbidity (high blood pressure, type 2 diabetes, sleep apnea, etc.)
• A history of attempted lifestyle intervention (often 3–6 months)
• Clinical notes describing weight-loss goals and counseling provided

PA requests can take a few business days to a few weeks. If denied, you typically have the right to appeal. The WeightWise Coverage Navigator helps you organize this paperwork ahead of your appointment.

A note on compounded GLP-1s

You may have seen telehealth ads for compounded semaglutide or tirzepatide at much lower prices. Compounded medications are produced by compounding pharmacies and are not FDA-approved versions. They exist in a more limited regulatory space — quality, sterility, and dosing accuracy can vary by pharmacy. WeightWise does not sell compounded medications. If you're considering one, talk with a licensed clinician about the risks and how to evaluate a compounding pharmacy.
