Insurance and GLP-1s: how to ask for coverage

Wegovy or Zepbound denied? Here is how coverage works, what prior authorization means, how to appeal, and where to find savings programs.

Key terms

Term	Meaning
Formulary	Your plan’s list of covered drugs
Prior authorization (PA)	Your prescriber must show the drug is needed before the plan pays
Step therapy	The plan wants you to try other treatments first
Appeal	Asking the plan to reconsider a denial

Steps to take

Check your formulary online, or call the number on your card.
Ask your prescriber to submit prior authorization with your health details.
If denied, ask why, in writing.
Appeal: your prescriber can send a letter of medical necessity. You have the right to an internal appeal and often an external review (HealthCare.gov).
Look at savings programs from the manufacturer. Eligibility varies, and the terms change — manufacturer savings cards commonly exclude anyone on government insurance, so check the current terms on the maker’s own site rather than a summary.

What helps an appeal

your diagnosis and health history
other conditions the medicine may help, such as blood pressure, sleep apnea or heart risk
what you’ve tried before
your prescriber’s letter

A real-life example

Joy, 46, was denied Zepbound. Her prescriber resubmitted with her sleep apnea diagnosis and past treatment attempts. The appeal was approved six weeks later.

Keep records

Save every letter, reference number and call date. It makes appeals much easier.

Common questions

Does Medicare cover Wegovy?

This one changes often enough that any specific answer printed here would go stale, so we won’t print one. Check your own plan, and ask specifically about the approved uses beyond weight — a cardiovascular or sleep apnea indication can change the answer where weight alone doesn’t.

Can my employer plan exclude weight-loss drugs?

Some plans do. Ask HR whether coverage is changing.

What’s a letter of medical necessity?

A letter from your prescriber explaining why you need the medicine.
