From recent overturned decisions
“The physician reviewer found that Nature of Statutory Criteria/Case Summary: A patient has requested reimbursement for collagen crosslinks testing. High levels of bone turnover markers can predict faster rates of bone loss and increased fracture risk in patients with osteoporosis. A study that looked at the relationship between bone density and markers of bone turnover found that in women treated …”
“Nature of Statutory Criteria/Case Summary: A patient has requested reimbursement for polymerase chain reaction (PCR) testing for Ehrlichia chaffeensis, Borrelia miyamotoi, Anaplasma phagocytophilum, and Babesia microti. The records indicate that this patient was evaluated and assessed as having inflammatory arthritis of the spine. In this case, testing for infectious diseases was supported rather than empiric treatment without further testing. There …”
“Nature of Statutory Criteria/Case Summary: A patient has requested reimbursement for a collagen crosslinks test. Findings: The physician reviewer found that International Osteoporosis Foundation and the International Federation of Clinical Chemistry (IFCC) identify carboxy-terminal crosslinking telopeptide of type 1 collagen (CTX-1) in blood as the reference markers of bone turnover for fracture risk prediction and monitoring of osteoporosis treatment. The …”
And one the reviewer upheld
“Nature of Statutory Criteria/Case Summary: An enrollee has requested reimbursement for Prometheus Anser ADA diagnostic test. The records provided for review document that this patient demonstrated clinical improvement in her symptomatic Crohn’s disease with vedolizumab (Entyvio) treatment. The patient previously underwent treatment with Humira without substantial control of her Crohn’s disease. The provider recommended Prometheus Anser ADA diagnostic testing, which …”
- 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 Lab Work denials for Orth/Musculoskeletal overturned?
In 27 California IMR decisions from 2010 to 2025, reviewers overturned 16 (59.3%). In the last five years: 88.9% of 9. , 27 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.
