I request that the denial be overturned and the surgery approved. 1. The denial. [Insurer] denied this surgery stating, verbatim: "[paste the exact denial language from your letter]." 2. Why the denial is incorrect. [State, in one or two sentences, why the service is medically necessary for your condition, and answer the specific reason the plan gave.] 3. The controlling standard. [See the standard for this denial type below, then cite it here.] 4. The evidence. I am attaching: - A letter of medical necessity from my treating provider addressing each clinical criterion; - [Your supporting records: see the document checklist below]; - The clinical guidelines and records that support coverage. 5. My request. I request a full reversal of this denial and approval of [service or medication] within the timeframe required by law. If the denial is upheld, please provide in writing the specific clinical criteria used, the credentials of the reviewing clinician, and instructions for independent external review. Under 29 C.F.R. 2560.503-1 (employer plans) or 45 C.F.R. 147.136 (ACA plans), please also provide all documents and records relevant to this claim. Sincerely, [Patient name / authorized representative]
The controlling standard for surgery denials
Medical-necessity review against the plan's own clinical criteria (MCG or InterQual), which the plan must disclose on request under ERISA § 503 and 45 C.F.R. § 147.136.
What makes a surgery appeal letter win
Force the carrier to disclose the clinical criteria they used. Have the surgeon write a letter of medical necessity addressing each criterion. Attach prior conservative-therapy documentation. Request a peer-to-peer review with the plan's medical director.
The letters that get overturned share a structure: they quote the denial, rebut the plan's specific criteria point by point, cite the controlling standard above, attach a treating-provider letter of medical necessity, and make a clear demand for reversal. Generic letters that simply ask the plan to reconsider do not move reviewers.
Documents to attach
- The denial letter
- Insurance card (front + back)
- Surgeon's pre-operative notes
- Imaging reports (MRI, X-ray, CT)
- Conservative-therapy records (PT, medication trials)

Build my appeal free →Surgery appeal: frequently asked questions
Can I appeal your my insurer surgery denial?
Yes. Pre-service (prior authorization) and post-service surgical denials are both appealable. Force your insurer to disclose the clinical criteria (MCG or InterQual) it applied, then have your surgeon rebut each criterion in a letter of medical necessity.
How long do I have to appeal your my insurer surgery denial?
Internal appeals are generally due within 180 days of the denial. Urgent pre-service appeals are decided in 72 hours, standard pre-service in 30 days, and post-service claim appeals in 30 to 60 days.
Why did my insurer call my surgery 'not medically necessary'?
Most surgical denials cite unmet criteria or missing documentation of conservative therapy such as physical therapy, weight loss, or medication trials. Documenting those prior treatments and mapping them to the carrier's own criteria is the core of the appeal.
What documents strengthen your my insurer surgery appeal?
The denial letter, your surgeon's pre-operative notes, imaging reports, and records of prior conservative therapy. A peer-to-peer review between your surgeon and the plan's medical director often resolves these before external review.
