Sinus Surgery denials in California external review
In the California DMHC record, independent physician reviewers decided 155 published external-review cases involving Sinus Surgeryand overturned the plan’s denial in 63.9%. That is a historical result among cases that reached this program, not a forecast for an individual appeal.
Conditions behind Sinus Surgery denials
| Category | Decisions | Overturned |
|---|---|---|
| Sinusitis | 110 | 71.8% |
| Nasal Air Obstruct | 9 | 44.4% |
| Deviated Septum | 6 | 50% |
| Rhinitis | 5 | 80% |
What the insurer actually argued
| Reason given | Decisions | Overturned |
|---|---|---|
Medical Necessity The plan said the care wasn’t medically necessary. The most common fight, and the most winnable. | 100 | 82% |
Experimental/Investigational The plan called the treatment unproven. These turn on published evidence, so the appeal is a literature argument. | 53 | 32.1% |
What the reviewers wrote
Where the denial was overturned
Nature of Statutory Criteria/Case Summary: An enrollee has requested authorization and coverage for (1) radiofrequency ablation of the posterior nasal nerve area and/or (2) low-dose radiofrequency intranasal tissue remodeling of the nose. Chronic rhinitis is an inflammatory condition of the nasal cavity, which typically manifests as nasal obstruction and excessive nasal discharge. It can be triggered by allergic stimuli, non-allergic stimuli, or a combination of the two. Standard medical therapies for chronic rhinitis include intranasal corticosteroids, intranasal antihistamines, and intranasal anticholinergics. For cases recalcitrant to medical therapy, surgical options include inferior turbinate reduction, Vidian neurectomy, and posterior nasal neurectomy.
Nature of Statutory Criteria/Case Summary: A patient has requested reimbursement for Nasal/sinus endoscopy, surgical, with dilation (eg, balloon dilation); maxillary sinus ostium, trans-nasal or via canine fossa, nasal/sinus endoscopy, surgical, with dilation (eg, balloon dilation); frontal and sphenoid sinus ostia, and nasal/sinus endoscopy, surgical with ethmoidectomy; partial (anterior), with the approved submucous resection inferior turbinate, partial or complete, any method. Balloon dilation of the sinuses can be beneficial for patients with either recurrent acute, or chronic rhinosinusitis. Balloon dilation of the sinuses offers a significant benefit over traditional functional endoscopic sinus surgery as it carries less morbidity and can frequently be accomplished in an office setting.
Where the denial was upheld
Nature of Statutory Criteria/Case Summary: The patient has requested authorization and coverage for surgical procedures including balloon dilation of the maxillary, frontal, and/or sphenoid sinus ostia and/or turbinate resection. Balloon dilation of the sinuses can be beneficial for patients with either recurrent acute, or chronic rhinosinusitis. Balloon dilation of the sinuses offers a significant benefit over traditional functional endoscopic sinus surgery as it carries less morbidity and can frequently be accomplished in an office setting. Balloon dilation of the sinuses should only be recommended to patients who meet the criteria for the diagnosis of rhinosinusitis and who are refractory to maximal medical management including the use of intranasal saline, topical steroids, and antibiotics.
Nature of Statutory Criteria/Case Summary: An enrollee has requested reimbursement for Propel mometasone sinus implant for treatment of the enrollee, who has a history of chronic sinusitis. Findings: 2/3 of the physician reviewers found that the patient has persistent nasal blockage and congestion. A computed tomography (CT) scan showed extensive ethmoid polypoid sinonasal obstruction. His medications have included an intranasal antihistamine and nasal steroid combination spray as well as oral levocetirizine and pseudoephedrine. The documentation did not mention any relief obtained with these medications, nor was there any mention of preoperative steroid use demonstrating any benefit or lack thereof to reduce symptoms. The nasal septum was mentioned to be deviated to the right with some 2+ hypertrophy of the inferior turbinates. No polyps were mentioned on this examination.
Figures and quotations on this page come from 42,749 published decisions in the California DMHC Independent Medical Review dataset. These are California external-review outcomes. Other state and federal programs have different eligibility rules, processes, and current availability; the rates here do not transfer to those programs or predict an individual result. Excerpts are quoted verbatim from the public record and describe this treatment generally, not any individual case.
These outcomes describe eligible cases completed through California DMHC’s Independent Medical Review program. They do not estimate the chance that an internal appeal, an external review in another jurisdiction, or your individual case will succeed.
