How Does Commercial Insurance Prior Authorization Work for GLP-1 Medications?
INS-000003
Direct Answer
Prior authorization is a process where your insurance company requires your doctor to submit documentation proving medical necessity before approving coverage for a GLP-1 medication. Nearly every commercial plan that covers these medications requires it. Coverage odds vary significantly by what the prescription is coded for, roughly 85 percent of commercial plans cover Ozempic for diabetes, compared to roughly 45 percent covering Wegovy for weight loss.
Why Coverage Follows the Indication, Not the Drug
This is the single most important thing to understand: insurance coverage follows the FDA-approved indication your prescription is written for, not simply which drug you're taking. Ozempic and Wegovy share the same active ingredient, semaglutide, but a plan can cover one and deny the other, because they're approved for different uses and coded differently.
What Documentation Is Typically Required
For a diabetes-indication prior authorization, plans commonly want documented A1C levels, current use of metformin or documentation of why it isn't appropriate, and your diagnosis. For a weight-management indication, plans typically want BMI documentation (usually 30 or higher, or 27 or higher with a weight-related comorbidity), and documentation of prior supervised diet and exercise attempts, often 3 to 6 months' worth.
Practical Steps
Call the number on your insurance card and ask specifically: is this medication covered on my formulary for this diagnosis code, what tier is it on, and is prior authorization required? Bring your BMI documentation, relevant lab values, and any records of prior weight-management attempts to your appointment, so your provider has what they need to submit a complete request the first time.
