What should I do first after a coverage denial?

A denial is common and not the end of the road. First, read the denial notice for the specific reason — it will usually cite a missing prior authorization, a step-therapy rule, or a formulary exclusion, and each has a different next step. Then ask your prescriber about an appeal, since many denials are overturned when the office submits additional documentation or a letter of medical necessity.

Can a coverage denial be appealed?

Yes. Most plans have both an internal appeal and, if that fails, an external review by an independent party. Many denials are overturned when your prescriber's office submits additional documentation or a letter of medical necessity. Appeal rights and timelines depend on your plan and where you live, so confirm the specifics with your insurer.

How long do I have to appeal a denial?

Appeal windows are time-limited, so note the deadlines and keep copies of everything. The exact timelines depend on your plan and where you live — confirm the specifics directly with your insurer so you don't miss a window.

A denial is common and is not the end of the road. Two things to do first:

Read the denial notice for the specific reason. It will usually cite a missing prior authorization, a step-therapy rule, or a formulary exclusion — each has a different next step.
Ask your prescriber about an appeal. Many denials are overturned when the office submits additional documentation or a letter of medical necessity. Most plans have both an internal appeal and, if that fails, an external review by an independent party.

Keep copies of everything and note deadlines — appeal windows are time-limited.

This is peer information, not medical advice. Appeal rights and timelines depend on your plan and where you live; confirm the specifics with your insurer.

How to determine if your insurance formulary covers GLP-1 medications — Before you can get a GLP-1 medication covered, you need to know if it's on your plan's formulary — and where. Here's how to check, what the tiers mean, and who actually decides what's on the list in the first place.

Understanding insurance coverage for GLP-1 medications — Coverage for GLP-1 medications hinges on three levers — formulary, prior authorization, and step therapy — plus a fourth most people miss: whether the prescription is for diabetes or weight management. Here's how each actually works, and how to build your best case for coverage.

How compounded GLP-1 medications are made — and how that differs from the branded pens — A compounded GLP-1 isn't a knockoff pen off a production line — it's mixed from raw active ingredient at a pharmacy. Here's how the drug substance is sourced, how the formula and dose are set, how a sterile compounding pharmacy actually makes the vial, and how all of that compares with the tightly controlled, FDA-approved process behind Ozempic, Wegovy, and Zepbound.

How to verify a pharmacy is legitimate: BeSafeRx, NABP, and your state board — Our sourcing guides keep ending on the same instruction — verify the pharmacy with your state board, the NABP, or FDA's BeSafeRx — without saying how. This is the step-by-step: the free tools each one offers, what red flags to look for, how to pull a pharmacy's license record, and how to check your own pen's lot number against FDA's counterfeit alerts. About five minutes, start to finish.

LillyDirect vs. NovoCare: how manufacturer direct-pay actually works — Both GLP-1 makers now sell their own brand medications straight to cash-paying patients — Lilly through LillyDirect, Novo Nordisk through NovoCare. Here's what these direct-pay channels actually are, how single-dose vials differ from pens, how a flat cash price differs from a savings card, and the problems direct-pay doesn't solve.
