Checking your coverage

Call your insurance

Call the number on your insurance card and ask:

  • Is [medication name] covered on my plan?
  • What's my copay/coinsurance?
  • Is prior authorization required?
  • Are there quantity limits?
  • What formulary tier is it?
  • Are there step therapy requirements? (must try other medications first)
  • Does my plan exclude weight loss medications?

Prior authorization

What it is

Many insurance plans require prior authorization — your provider must justify why you need the medication before insurance will cover it.

What your provider submits

  • Your diagnosis (obesity, diabetes, etc.)
  • BMI documentation
  • Comorbid conditions (hypertension, sleep apnea, etc.)
  • Previous weight loss attempts
  • Medical necessity justification

Timeline

Typically 3-7 business days for decision. May be faster if urgent. You can appeal if denied.

What you can do

  • Provide complete medical history to provider
  • Document previous weight loss attempts
  • Follow up with insurance if delayed
  • Be patient but persistent

What to do if denied

Don't give up — appeal

Many initial denials are overturned on appeal. Process:

  1. Request written denial reason — insurance must provide
  2. Work with your provider on appeal letter — address specific denial reason
  3. Provide additional documentation — medical records, BMI history, comorbidities
  4. Submit appeal within timeframe — typically 30-180 days
  5. Follow up regularly — appeals can take 30+ days
  6. Consider external review — if internal appeal denied

Common denial reasons and responses

  • "Not medically necessary" — provide documentation of BMI, comorbidities, failed alternatives
  • "Step therapy required" — document previous medication trials or contraindications
  • "Cosmetic/use for weight loss only" — document medical conditions related to weight
  • "Excluded benefit" — may need to explore other insurance options

If insurance won't cover

Manufacturer savings cards

See our cost guide for current savings card options. Can reduce cost significantly for commercially insured patients.

Compounded medications

See our compounded GLP-1 guide. Much cheaper ($200-400/month) but less regulated.

Patient assistance programs

Manufacturers offer free medication for low-income uninsured patients. Apply through manufacturer websites.

Payment plans

Some pharmacies and telehealth platforms offer payment plans. CareCredit may be an option.

Switch insurance plans

During open enrollment, look for plans that cover GLP-1 medications. May be worth higher premium for coverage.
