From recent overturned decisions
“The physician reviewer found that the patient has requested authorization and coverage for a continuous passive motion device. Experts noted `Judet quadricepsplasty is an effective method to treat knee extension contracture and improve knee range of motion (ROM). It should be performed by an experienced orthopedic surgeon and followed by physiotherapy with continuous passive motion (CPM). ` The combined treatment …”
“The patient has requested authorization and coverage for continuous passive motion (CPM). Researchers concluded that both CPM and conventional physical therapy are beneficial for the treatment of adhesive capsulitis in diabetic patients. However, the authors found that CPM provided distinctive improvements in the function and pain levels of adhesive capsulitis patients. This patient was diagnosed with left shoulder adhesive capsulitis. …”
“Nature of Statutory Criteria/Case Summary: An enrollee has requested reimbursement for the continuous passive motion (CPM) machine for treatment of the enrollee’s left hip status post arthroscopy. Findings: The physician reviewer found that in the medical literature, it is noted that some patients are treated post-operatively with a CPM machine and a hip brace. The authors state that “athletes undergoing …”
And one the reviewer upheld
“The physician reviewer found that a patient has requested reimbursement for a continuous passive motion device. Per the medical records, the patient underwent left knee anterior cruciate ligament (ACL) autograft hamstring reconstruction followed by postoperative use of a continuous passive motion machine. Most rehabilitation programs following ACL reconstruction, supported by current medical literature, include immediate weight-bearing, early range of motion …”
- 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 CPM Machine denials for Orth/Musculoskeletal overturned?
In 101 California IMR decisions from 2003 to 2026, reviewers overturned 41 (40.6%). In the last five years: 12.5% of 8. 92 were medical-necessity disputes, 9 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.
