Surgery Denied by Health Insurance
What can I do if insurance denies my surgery?
A surgery denial can affect planned treatment or a bill for care already received. Ask what exactly was denied: the procedure, admission status, location, surgeon, or another service. Work with the care team on clinical decisions while you address coverage.

A surgeon, hospital, anesthesiologist, and other clinicians may generate different authorizations and claims. List the denied request and the affected dates. Ask whether a medical group or utilization reviewer made the initial decision and where the member appeal must be filed.
Verify the authorization scope
Check approval dates, procedure, facility, and other stated limits. Authorization does not guarantee every benefit requirement or payment. If the submitted claim differs from an approval, ask the billing team to review the facts and correct inaccuracies rather than changing the record to fit coverage.
Prepare a clinical response when needed
For medical necessity, ask the surgeon or treating clinician to address the denied criteria using examination findings, relevant tests, prior treatment, and the reason for the proposed procedure or setting. If a peer-to-peer discussion is offered, confirm its deadline and whether a separate formal appeal is still required.
Discuss timing and financial exposure
Ask the clinician whether a delay creates a health risk and whether expedited review is appropriate. For planned care, request a written explanation of coverage status and potential patient responsibility before agreeing to a financial arrangement. This guide cannot determine whether postponing or proceeding is medically appropriate.
If surgery already occurred
Obtain the EOBs and itemized accounts. Ask whether provider contract terms or applicable billing protections affect liability. Appeal the actual coverage decision and request a billing hold separately. If the plan upholds a clinical denial, review the final notice for independent review options specific to your plan.
Which plan rules apply?
For commercial coverage, check the policy and state-specific instructions. A self-funded employer plan can use different oversight and appeal rules even when an insurer administers claims. Medicare and Medicaid use program-specific notices and review routes. Confirm the applicable deadline, whether a correction counts as an appeal, and where to escalate; do not substitute a deadline from a different plan.
