What if insurance won’t cover my GLP-1?

A denial letter can make it feel like you’re arguing with a printer. Start by finding out which argument you’re actually having.

“Not covered” might mean a missing prior authorization, a preferred alternative, incomplete documentation, or an exclusion in the benefit itself. Those are different problems, and sending the same form again doesn’t fix all of them.

Ask for the specific reason in writing

Get the denial, the coverage criteria, and the appeal deadline. Ask your prescriber’s office whether the submitted diagnosis and documentation accurately reflect your situation. Keep dates, reference numbers, and copies; your future self will appreciate not reconstructing the entire saga while on hold.

HealthCare.gov explains internal appeals and external review. Which route applies depends on your plan and the type of denial. An appeal can correct a bad decision or incomplete record; it does not guarantee coverage for a benefit your plan excludes.

Have a second conversation while the first one crawls along

Ask about a covered medication that fits your needs, legitimate manufacturer assistance or self-pay options, and what to do if treatment is interrupted. Use your actual medical history—changing a diagnosis just to get a claim through is not a solution.

If you have Medicare drug coverage, read the Medicare Part D bridge program answer. It has specific eligibility rules and is not the same thing as a commercial insurance savings card.

There isn’t a clinical trial that can tell us what your particular benefits department will approve. Here, the useful evidence is the written policy and the medical record.

A helpful question for the plan: “Is this a documentation problem, a clinical-criteria denial, or a benefit exclusion—and what is the next available review step?”
