How do I get a GLP-1 approved by my insurance?

Most plans require prior authorization: your clinician documents your BMI and any weight-related conditions and submits the required diagnosis codes. If the plan denies it, you can appeal with a letter of medical necessity and complete records. Criteria vary by plan.

What diagnosis codes are used for GLP-1 coverage?

Weight coverage commonly uses ICD-10 obesity codes such as E66.9 plus Z68 BMI codes, along with codes for comorbidities. A type 2 diabetes diagnosis supports coverage of the diabetes-approved brand. Your clinician selects the codes that match your record.

How to Get a GLP-1 Covered by Insurance

Medically reviewed by Editorial Medical Review, MD, NAMS-CMP · Updated July 2026

Quick answer

Getting a GLP-1 covered usually means clearing prior authorization: your clinician documents your BMI and any weight-related conditions, submits the required diagnosis codes, and appeals a denial if needed. For women, PCOS or a diabetes diagnosis can change which codes and criteria apply. Coverage rules vary by plan, so confirm yours directly.

Start with prior authorization

Most plans that cover GLP-1 drugs require prior authorization, meaning the plan must approve the prescription before it is filled. Your prescriber submits clinical information showing you meet the plan criteria, which typically include a BMI threshold and sometimes a documented attempt at lifestyle change.

Ask your clinician or the plan for the specific prior-authorization criteria up front, so the first submission includes what the plan wants rather than triggering an avoidable denial.

Document BMI, comorbidities, and diagnosis codes

Coverage for weight often hinges on documented BMI (recorded with ICD-10 codes such as E66.9 for obesity, plus Z68 codes for the BMI value) and any weight-related conditions like hypertension, high cholesterol, or type 2 diabetes. A diabetes diagnosis can make a semaglutide or tirzepatide product easier to cover under its diabetes-approved brand.

For women, a PCOS diagnosis (ICD-10 E28.2) is relevant context, though no GLP-1 is approved for PCOS itself, so coverage still generally runs through weight or diabetes criteria. Accurate coding by your clinician is what makes the paperwork match the policy.

Appeal a denial

A denial is not the end. Plans have an appeals process, and appeals with a clear letter of medical necessity, complete BMI and comorbidity documentation, and the relevant records are often how coverage is ultimately obtained. Manufacturer savings programs can bridge cost while an appeal is pending, subject to eligibility.

Keep copies of every submission and note deadlines, since appeals are time-limited. Persistence with complete documentation is the practical difference-maker.

A type 2 diabetes diagnosis supports coverage of the diabetes-approved brand. Your clinician selects the codes that match your record.
Does a PCOS diagnosis help with coverage?: PCOS (ICD-10 E28.2) is relevant context, but no GLP-1 is approved for PCOS, so coverage still generally runs through weight or diabetes criteria. Accurate coding plus BMI and comorbidity documentation is what aligns the request with the policy.
