From recent overturned decisions
“The physician reviewer found that Nature of Statutory Criteria/Case Summary: A patient has requested authorization and coverage for a cochlear implant device and a surgical implantation procedure. The benefits of treating single-sided deafness with cochlear implants have been documented in the literature, including improvements in word comprehension, sentence recognition, and tinnitus. Cochlear implant placement is U.S. Food and Drug Administration …”
“Nature of Statutory Criteria/Case Summary: The patient’s parent has requested authorization and coverage for left cochlear implantation surgery with or without mastoidectomy. Cochlear implants (CIs) have been used to treat sensorineural hearing loss for over 40 years. Traditionally, CIs have been utilized for bilateral hearing loss when conventional amplification techniques do not provide adequate hearing rehabilitation. The benefits of treating …”
“Nature of Statutory Criteria/Case Summary: The patient has requested authorization and coverage for a surgical cochlear implant. Findings: The physician reviewer found that Cochlear implants have traditionally been used to treat bilateral sensorineural hearing loss in the presence of normal cochlear anatomy when conventional amplification techniques do not provide adequate hearing rehabilitation. However, the benefits of treating unilateral hearing loss …”
And one the reviewer upheld
“Nature of Statutory Criteria/Case Summary: The patient has requested authorization and coverage a cochlear implant consultation. While cochlear implantation for single sided deafness has been shown to be safe and effective, the U.S. Food and Drug Administration notes that it is indicated for single sided deafness that is defined as profound sensorineural hearing loss. In this case, given that the …”
- 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 Cochlear Implant denials for Ears/Nose/Throat overturned?
In 28 California IMR decisions from 2004 to 2025, reviewers overturned 9 (32.1%). In the last five years: 45.5% of 11. 27 were medical-necessity disputes, 1 experimental/investigational.
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.
