Keyword matches on the reviewer’s findings, not causes. A tag that appears mostly in overturned decisions is worth documenting in an appeal; it is not a guarantee.
From recent overturned decisions
“The physician reviewer found that a patient has requested authorization and coverage for a Botox injection on each side of the face. Current medical literature supports the use of Botox for temporomandibular joint disorder-related migraine pain. Per the medical records, the patient has temporomandibular joint disorder and migraines and has tried and failed treatment with nonsteroidal anti-inflammatory drugs (NSAIDs), gabapentin, …”
“The physician reviewer found that a patient has requested authorization and coverage for Botox 50-100 units to the masseter muscles every three to six months. In this case, the patient has temporomandibular disorder (TMD) with associated masseter hypertrophy. The record establishes that the patient has symptoms that have been recalcitrant to multiple conservative therapies. Overall, Botox has been shown to …”
“The physician reviewer found that a patient has requested authorization and coverage for Botox injections. Initial conservative therapeutic options for temporomandibular joint disorder include oral anti-inflammatories, a trial of a soft diet, occlusal splinting, physical therapy, or massage. In cases involving masseter hypertrophy, Botox has emerged as a safe and efficacious second-line therapy. In this case, the patient has a …”
And one the reviewer upheld
“The physician reviewer found that Nature of Statutory Criteria/Case Summary: A patient has requested authorization and coverage for Botox injections. A concise review of the literature regarding current management options/guidelines for temporomandibular disorder (TMD) recommends physical therapy and acupuncture/dry needling. A systematic review and meta-analysis found that Botox was only slightly more effective than placebo at reducing pain at one …”
- 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 Botox Injection denials for Orth/Musculoskeletal overturned?
In 88 California IMR decisions from 2002 to 2025, reviewers overturned 43 (48.9%). In the last five years: 50.0% of 18. 39 were medical-necessity disputes, 49 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.
