What's the difference between a formulary exclusion and a plan exclusion?
Formulary exclusion: the specific drug isn't on the insurer's approved list, but the drug category may still be covered — you might get a different GLP-1 approved instead. Plan exclusion: the entire treatment category (like weight loss drugs) isn't covered at all. No drug in that class will be approved.
How do I prove I've completed step therapy?
Pull medical records showing you took the required medication, how long you were on it, and why it didn't work (side effects, no improvement, etc.). Your doctor's office can help gather this. Pharmacy fill records also serve as proof.
Can I appeal a denial for "off-label" use?
You can try, but the odds are against you. Insurers aren't legally required to cover off-label prescriptions. A successful appeal needs published medical literature and proof that on-label alternatives don't work for you. Honestly, switching to an FDA-approved drug for your condition is usually the faster path.
What does "not medically necessary" actually mean?
It means the insurer says you don't meet their specific checklist — wrong diagnosis, BMI too low, haven't tried the required first-line drugs. Your denial letter should spell out which box you didn't check.
How do I request a "formulary exception"?
Your doctor submits a formal request explaining why the drugs on the formulary won't work for you — documented side effects, treatment failures, or medical conditions that rule them out. It's a higher bar than a standard prior authorization.
Is it my doctor's job or my job to handle the appeal?
Both. Your doctor provides the medical justification and clinical documentation. You're responsible for making sure paperwork gets submitted on time and following up. Don't assume it's being handled — track every step yourself.
What is an external review?
An independent review by someone outside your insurance company, available after you've used up internal appeals. The reviewer's decision is typically binding on the insurer. It's your last shot within the insurance system.
