Getting GLP-1 Medication Covered by Insurance

Step one: the phone call

Five minutes on the phone beats any amount of guessing or forum reading. Call the member services number on the back of your insurance card and ask these questions in this order:

1. "Is semaglutide — Wegovy — covered on my plan for weight management?" Ask about tirzepatide (Zepbound) separately; they are often treated differently.
2. "Does my plan exclude weight-loss medication as a category?" This is the question that saves the most time. Many employer plans exclude it by policy, and if yours does, nothing else matters.
3. "What is the prior authorization requirement?" Get the specific criteria if you can.
4. "What would my copay be after prior authorization?" Coverage with a $400 copay is not the answer you were hoping for, and it is better to know now.
5. "Is there a step therapy requirement?" Some plans require you to try and fail a cheaper option first.

What coverage actually looks like in 2026

Prior authorization: what they usually want

Where coverage exists, it is almost always gated. The documentation typically requested:

• BMI, documented in your chart — usually 30+, or 27+ with a weight-related condition.
• A qualifying comorbidity — hypertension, type 2 diabetes, sleep apnoea, dyslipidaemia, fatty liver.
• Documented previous attempts at weight loss, often with dates and duration.
• Sometimes participation in a lifestyle programme, concurrent or prior.
• A letter of medical necessity from your prescriber.

When you are denied

First-submission denials are common and they are not final. A structured appeal succeeds more often than most people expect, because many denials are administrative rather than clinical.

1. Get the denial in writing and read the stated reason. 'Not medically necessary', 'not on formulary' and 'step therapy not completed' are three different problems with three different answers.
2. Ask for the specific criteria they applied. You are entitled to know what standard you failed.
3. File an internal appeal. There is a deadline — usually 180 days — and it is stated in the denial letter.
4. Get a stronger letter of medical necessity. It should name your BMI, every comorbidity, what you have already tried and for how long, and why this specific medication is indicated.
5. Request a peer-to-peer review, where your prescriber speaks directly to the insurer's medical reviewer. This works more often than the paperwork route.
6. Escalate to external review if internal appeals fail. An independent third party reviews it, and their decision binds the insurer.
7. Contact your state insurance commissioner if the process itself is being handled improperly.

If your plan excludes weight-loss medication as a category, appeals will not help — that is a benefit design decision, not a clinical one. In that case the realistic options are an employer benefits conversation, manufacturer direct-pay programmes, or self-pay.

If the answer is no

• Manufacturer direct-pay programmes. Both major manufacturers now offer cash pricing well below list — typically $350–$500 a month.
• Manufacturer savings cards, where you have commercial insurance that partially covers.
• Compounded medication, from $99 a month. The honest trade-offs are in Compounded GLP-1 Medication, Explained.
• FSA or HSA funds. Prescribed medication is generally an eligible expense — keep your receipts.
• A lower effective dose. Many people hold steady well below the maximum, which often costs less. GLP-1 Dosing and Titration, Week by Week.
