Frequently Asked Questions

How do I write a drug denial appeal letter?

Include: your name, member ID, prescription details, denial reference number, your doctor's statement of medical necessity, clinical evidence supporting the drug (studies, guidelines), why alternatives are not appropriate, and your request for coverage. Attach supporting medical records, lab results, and a letter from your prescriber. Keep a copy of everything.

How long do I have to appeal a drug denial?

Most plans allow 60 to 180 days from the denial date to file an appeal. Medicare Part D allows 60 days. Check your denial letter for the specific deadline and instructions. Do not wait until the last minute, as gathering documentation takes time. Request an expedited appeal if you need the medication urgently.

What is an external review for a drug denial?

An external review is an independent review by a third-party organization not affiliated with your insurer. You can request it after your internal appeal is denied. The external reviewer's decision is binding on the insurer. ACA-compliant plans and Medicare both offer external review rights. There is typically no cost to you for the review.
