What the insurer actually argued
Denials fall into different categories, and they don’t succeed equally — so the reason on your letter changes how you should answer it.
| Reason given | Decisions | Overturned |
|---|---|---|
Medical Necessity The plan said the care wasn’t medically necessary. The most common fight, and the most winnable. | 13 | 76.9% |
Experimental/Investigational The plan called the treatment unproven. These turn on published evidence, so the appeal is a literature argument. | 6 | 33.3% |

What the reviewers wrote

Where the denial was overturned
Nature of Statutory Criteria/Case Summary: At issue is whether the implantation of a hypoglossal nerve stimulator is likely to be more beneficial for the treatment of the patient’s condition than any available standard therapy. The patient had a diagnosis of sleep apnea. She is status post uvulopalatopharyngoplas. She reported that she discontinues continuous positive airway pressure (CPAP) ty (UPPP) and turbinate reduction.Findings: Two out of three physician reviewers found that the medical literature demonstrated that hypoglossal nerve stimulation led to significant improvements in objective and subjective measurements of the severity of OSA. This procedure is recognized by the American Academy of Otolaryngology Head and Neck Surgery to be an effective second-line treatment of moderate to severe obstructive sleep apnea.
An 18-year-old male has requested rhinoplasty for treatment of his deviated septum. Findings: The physician reviewer found that nasal septoplasty is a surgical procedure that has been shown to improve the functional breathing in patients with confirmed evidence both on physical examination, failure to improve with topical or oral medications, and x-ray evidence of bony deformity. The article by Stewart and colleagues documents the clinical findings, response to medications, as well as surgical outcomes in patients with confirmed nasal septal deformities. The authors reported that patients undergoing that surgical intervention improve substantially and have a better outcome. Rhinoplasty is a procedure designed to improve the external appearance of the nose. Alone, rhinoplasty usually is a cosmetic procedure.
Where the denial was upheld
Worth reading too — these show what an appeal has to overcome.
Nature of Statutory Criteria/Case Summary: The patient has requested authorization and coverage for implantation of a hypoglossal nerve stimulator. Findings: Two physician reviewers found that CPAP is the most common type of therapy for patients with severe OSA. Hypoglossal nerve stimulation therapy has been proven by the U.S. Food and Drug Administration (FDA) to be an effective modality of treatment of OSA in patients with tongue-based obstruction.
Nature of Statutory Criteria/Case Summary: An enrollee has requested authorization and coverage for hypoglossal nerve stimulator (CPT 64568 and CPT 0466T). The U.S. Food and Drug Administration (FDA) has approved hypoglossal nerve stimulation for the treatment of moderate to severe obstructive sleep apnea (OSA) refractory to continuous positive airway pressure (CPAP). However, research comparing its effectiveness to existing alternatives, such as airway surgery or oral appliances, is lacking. Researchers conducted a systematic review comparing oral appliances and CPAP in adult patients with mild to severe OSA. The authors found that although CPAP improved apnea/hypopnea index (AHI) scores more than oral appliances, CPAP users also showed significantly worse compliance with their devices.
Figures and quotations on this page come from 42,749 published decisions in the California DMHC Independent Medical Review dataset. These are California outcomes — every state runs an equivalent external review, but the rates here are California’s. Excerpts are quoted verbatim from the public record and describe this condition generally, not any individual case.
How to use this in your appeal
These outcomes come from California’s external review program — an independent physician panel whose decision binds the insurer. Every state has an equivalent, and internal appeals succeed even more often. If your care for obstructive airway was denied, the published record says the denial is worth fighting.
