Action Plan
What to Do When Your Insurance Denies Your Medication
5 min read · Updated February 2026
You went to the pharmacy and your medication wasn't covered. Or your doctor's office called to say the insurance company denied the prior authorization. Either way, you need your medication and someone is standing in the way. Here's your action plan.
If This Is Urgent
If you're in active treatment (e.g., chemotherapy, transplant medications, insulin) or missing this medication could cause serious harm:
- Call your insurer and request an expedited/urgent appeal — they must decide within 72 hours
- Ask your doctor to call for an emergency peer-to-peer review
- Ask your pharmacy about a short-term emergency supply (many states require insurers to cover 72 hours of urgent medications)
- Contact the drug manufacturer's patient assistance program for bridge supply
Step 1: Get the Denial in Writing (Day 1)
If you haven't already received a written denial letter, call your insurer and request one. You need:
- The denial reason — the specific clinical criteria or policy they used
- The denial code — use Ellen's Denial Decoder to understand what it means
- Your appeal deadline and instructions
- The name and credentials of the reviewer who denied your PA
Write down the date you received the denial — your appeal clock starts now.
Step 2: Call Your Doctor's Office (Day 1-2)
Tell them the PA was denied and ask them to:
- Request a peer-to-peer review — your doctor calls the insurance company's medical director directly. This is often the fastest resolution.
- Write a letter of medical necessity explaining why this exact medication is needed
- Gather supporting records: lab results, imaging, treatment history, prior medication failures
Be specific with your doctor about what was denied and why. The more targeted the response, the better.
Step 3: Understand Why You Were Denied
Most medication denials fall into a few categories. Understanding yours determines your strategy:
"Step therapy required"
You must try a cheaper drug first. Strategy: Document why the cheaper drug won't work for you (prior failure, contraindication, medical evidence).
"Not medically necessary"
The insurer disagrees with your doctor. Strategy: Peer-to-peer review + clinical evidence (NCCN guidelines, peer-reviewed studies).
"Non-formulary" or "Not covered"
The drug isn't on the insurer's approved list. Strategy: Formulary exception request with medical necessity documentation.
"Experimental/Investigational"
Even for FDA-approved drugs. Strategy: Cite FDA approval date, NCCN Compendium listing, and state mandate laws.
Step 4: File Your Appeal (Week 1-2)
Don't wait. File your internal appeal as soon as your supporting documentation is ready. Include:
- Cover letter referencing your denial case number
- Doctor's letter of medical necessity
- Clinical evidence supporting your medication
- Your treatment history and prior medication failures
- A personal statement about the impact on your health
Ellen's Appeal Builder helps you organize all of this into a compelling package.
Key Timelines to Remember
Who to Call When You're Stuck
- Your insurer's member services — ask for the PA/appeals department specifically
- Your state insurance department — they handle complaints and can intervene
- Patient advocacy organizations — disease-specific nonprofits often have staff dedicated to helping with appeals
- Your employer's HR/benefits team — if you have employer-sponsored insurance, they can sometimes escalate with the insurer directly
- For Medicare: 1-800-MEDICARE (1-800-633-4227)
- For Marketplace plans: Healthcare.gov or your state exchange
Don't Give Up
Insurance companies count on patients giving up after the first denial. But the data shows that appeals work — especially when backed by strong clinical evidence and a persistent doctor. You have legal rights to challenge every denial, and the new 2026 CMS rules are making the process more transparent and accountable than ever.
