What to do after a surgery denial letter from your insurer

On Behalf of | Jan 29, 2026 | Health Insurance Claims

If your health insurance denies coverage for a surgery, you still have options. That letter doesn’t have to be the final word, but acting fast and responding the right way matters. Here’s what you should do immediately.

Check the letter for the reason your claim was denied

The denial letter will tell you why your surgery wasn’t covered, and that reason sets the tone for your appeal. It may state that the procedure wasn’t medically necessary, wasn’t preapproved or involved an out-of-network provider. Whatever it is, your response should directly address that specific issue.

Ask your doctor for a supporting statement

Your doctor can help challenge the denial by writing a letter that explains why the surgery was necessary. The stronger the medical reasoning, especially when it uses language the insurer understands, the better chance you have of getting the claim approved on appeal.

File a formal appeal before the deadline

Most insurers give you a short window to file an appeal, and they include the steps in the denial letter. Follow those instructions exactly: include every form, attach your documents and keep a full copy of what you send. Even a small mistake can lead to another denial.

Request an external review if the appeal fails

If your appeal is denied again, you may qualify for an external review. In Ohio, that means a neutral third party reviews your case and makes a final decision. If they side with you, your insurer must pay for the surgery.

You still have options after the first “no”

A lot of denied claims can be overturned once you send in the right documents, follow the process and keep pushing back. If it gets too complicated or the insurer won’t budge, it may be time to get help from someone who knows how to fight for the care you were promised.
