Polysomnography denials in California external review
In the California DMHC record, independent physician reviewers decided 12 published external-review cases involving Polysomnographyand overturned the plan’s denial in 16.7%. That is a historical result among cases that reached this program, not a forecast for an individual appeal.

What the reviewers wrote
Where the denial was overturned
Nature of Statutory Criteria/Case Summary: The patient has requested authorization and coverage for a sleep study. In this case, the records indicate the presence of daytime fatigue, accompanied by snoring and hypersomnia, which was significant enough to contribute to a motor vehicle accident. Despite the absence of an elevated body mass index (BMI) or nocturnal hypoxemia, the records highlight the coexistence of insomnia and attention deficit hyperactivity disorder (ADHD), which are both potentially linked to undiagnosed sleep apnea. Researcherswith ADHD, such as difficulties concentrating, ineffective planning, and restlessness. The authors further note that the treatment of OSA is associated with an improvement in ADHD symptoms. As with ADHD, insomnia and OSA may also share overlapping symptoms.
Nature of Statutory Criteria/Case Summary: An enrollee has requested reimbursement for a sleep study test for evaluation of her history of daytime somnolence. Findings: The physician reviewer found that the submitted documentation supports the medical necessity of the services at issue. This patient presented with a clinical presentation that was suggestive of a sleep-related breathing disorder. In this case, the patient had significant malocclusion, dental crowding and a large tongue. Malocclusion has been linked to sleep-disordered breathing in recent publications. The presence of an enlarged tongue is also considered to be a potential risk factor for sleep-disordered breathing. There is sufficient evidence that correction of these anatomical abnormalities can lead to improvement/resolution in sleep-disordered breathing.
Where the denial was upheld
An enrollee has requested authorization and coverage for an in-center polysomnography test. American Academy of Sleep Medicine (AASM) guidelines recommend that polysomnography, or home sleep apnea testing with a technically adequate device, be used for the diagnosis of obstructive sleep apnea (OSA) in uncomplicated adult patients who present with signs and symptoms that indicate an increased risk of moderate to severe OSA. These guidelines recommend that if a single home sleep apnea test is negative, inconclusive, or technically inadequate, polysomnography should then be performed for the diagnosis of OSA.
Findings: The physician reviewer found that Nature of Statutory Criteria/Case Summary: A patient has requested authorization and coverage for continuous positive airway pressure (CPAP) equipment and/or the requested sleep study (CPT code 95810). Unlike the treatment of obstructive sleep apnea (OSA) in adults, the treatment of OSA in children is approached comprehensively, considering their unique needs and their developing physical characteristics. According to the medical literature, diagnostic testing for OSA should be performed in conjunction with a comprehensive sleep evaluation and adequate follow-up. An in-lab diagnostic polysomnogram (PSG) is the standard diagnostic test for the diagnosis of OSA in adult patients in whom there is a concern for OSA based on a comprehensive sleep evaluation.
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.
