From recent overturned decisions
“Nature of Statutory Criteria/Case Summary: The patient has requested authorization and coverage for a continuous positive airway pressure (CPAP) device (E0601) and supplies. As noted in the medical literature, a CPAP device is highly effective in treating patients with obstructive sleep apnea (OSA). The patient completed a diagnostic sleep study indicating an apnea-hypopnea index (AHI) ranging from five to 15 …”
“The physician reviewer found that Nature of Statutory Criteria/Case Summary: The patient has requested reimbursement for continuous positive airway pressure (CPAP) supplies including mask, nasal pillows, tubing, and filters. As noted in medical literature, obstructive sleep apnea (OSA) is a chronic disorder that requires lifelong care. Noncompliance of treatment with CPAP does not negate the requirement for adequate therapy. This …”
“Nature of Statutory Criteria/Case Summary: The patient has requested authorization and coverage for a continuous positive airway pressure (CPAP) device. The submitted documentation supports the medical necessity of the requested device. The patient reported symptoms of fatigue and sleepiness during the day. Additionally, he has a history of depression and insomnia. Medical literature defines obstructive sleep apnea as a polysomnogram-determined …”
And one the reviewer upheld
“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. …”
- California only: these are decisions by independent reviewers under California's IMR program (plans regulated by the Department of Managed Health Care). Other states and self-funded employer plans use different reviewers and rules.
- Selection: only denials that a member took all the way to IMR appear. Most denials are never appealed, and the ones that reach an external reviewer are not a random sample.
- Overturned means the reviewer disagreed with the plan; it does not mean the treatment worked or that a similar request will be approved.
- Argument tags are keyword matches on the reviewer's findings. They describe what the findings mention, not why the case was decided.
- Categories are DMHC's own labels (treatment sub-category and diagnosis category); 'Other' is a catch-all and is excluded from rankings.

Questions
How often were C-Pap Machine denials for CNS/ Neuromusc Dis overturned?
In 17 California IMR decisions from 2019 to 2025, reviewers overturned 12 (70.6%). In the last five years: 62.5% of 8. 17 were medical-necessity disputes.
What should an appeal document, based on these findings?
Whatever the plan's criteria ask for, shown in the record: the treatments already tried and their results, contraindications to the plan's preferred option, the guideline or evidence that supports the request, and the treating clinician's reasoning written to the criteria. The tag table shows which of these the reviewers mentioned most in overturned cases.
Does a California IMR result apply to my plan?
Only California plans regulated by the Department of Managed Health Care go to IMR. Other states and self-funded employer plans use different reviewers, but they weigh the same things.
Independent reviewers reverse plans when the record answers the criteria. Upload the denial letter; a senior reviewer reads it within 24 hours and tells you in writing whether it can be appealed and how. $0 upfront, 10% of what is recovered, nothing if we do not recover. Not a law firm.
