Question

What should I do if insurance denied my surgery?

Answer: Read the denial letter carefully to find whether the insurer is saying the surgery is not medically necessary, that prior authorization was missing, that conservative treatments should be tried first, or that records were insufficient. Then gather the surgeon's notes, imaging results, and treatment history and write an appeal that directly responds to the stated reason.

Why insurers deny surgery claims

Surgery denials most often come from a medical necessity review. The insurer's clinical reviewer looks at the submitted records and evaluates whether they support the conclusion that surgery is the appropriate treatment. Common triggers include a finding that conservative treatment has not been adequately tried first, that imaging or clinical records do not clearly demonstrate the problem requiring surgery, or that the records do not show why less-invasive options are not appropriate for this patient.

Prior authorization is the second major cause. Many surgeries require pre-approval before the procedure, and a missing or denied authorization can result in a claim denial even if the surgery was medically appropriate. A plan exclusion for specific procedures -- such as certain elective, cosmetic, or experimental surgeries -- is another denial basis that requires a different type of response.

The conservative treatment requirement

Many insurers require that a patient try and fail conservative non-surgical treatments before approving surgery. For orthopedic surgery, this might mean physical therapy, steroid injections, and bracing. For spine surgery, it might mean a course of physical therapy and pain management. For hernia repair or other procedures, it might mean watchful waiting unless symptoms are severe.

If the denial says conservative treatment has not been tried, the appeal should document what conservative options were attempted, how long they were tried, and why they failed or are not appropriate for this patient. If conservative treatment was tried and failed, include the treatment records that document it. If conservative treatment is contraindicated for clinical reasons, include the surgeon's explanation of why.

Clinical records that support a surgery appeal

The most important documents for a surgery appeal are the surgeon's operative note or preoperative assessment, diagnostic imaging reports (MRI, CT scan, or x-rays), clinical notes from the treating physician or specialist, records documenting symptoms and their severity, and any documentation of failed conservative treatment.

The surgeon's letter explaining the clinical rationale for the procedure is especially valuable. The letter should describe the diagnosis, the symptoms and functional limitations, the diagnostic findings that support the need for surgery, the conservative options considered and why they are not sufficient, and the expected outcome of surgery versus continued non-surgical management.

Writing the surgery denial appeal letter

Open with the patient name, member ID, the surgeon's name, the planned or performed procedure, the date of service, the claim number, and the denial reference. State that you are appealing and briefly describe the diagnosis and the surgery.

Then address the denial reason. If medical necessity is disputed, walk through the clinical evidence -- the diagnosis, the imaging findings, the functional limitations, the conservative treatment tried, and why surgery is the appropriate next step. If prior authorization is the issue, explain whether authorization was requested and what happened to the request. If a plan exclusion is cited, review the plan language carefully and argue why it does not apply if it seems incorrectly applied. Attach all supporting records. ClaimFighter can help convert the denial into an organized draft ready for review.

FAQ

What should I do if insurance denied my surgery?

Read the denial letter and identify the specific reason. Gather the surgeon's notes, imaging reports, records of conservative treatments tried, and any prior authorization documentation. Write an appeal that directly responds to the denial reason and explains the clinical basis for the surgical recommendation.

What if the insurer says I have not tried conservative treatment?

Document what conservative treatments were attempted, how long they were tried, and why they were unsuccessful or are not clinically appropriate. If conservative options are contraindicated, ask the surgeon to explain why in a letter. Include those records with the appeal.

Can I appeal a surgery denial if authorization was not obtained first?

Yes, though retroactive authorization appeals can be more difficult. Explain the circumstances -- for example, if the surgery was urgent and there was no time for prior authorization, or if the provider believed authorization was in place. Ask the insurer whether retroactive authorization is possible and submit the clinical documentation with the request.
