From recent overturned decisions
“The physician reviewer found that a patient has requested authorization and coverage for lumbar/sacral transforaminal epidural injection. Leading expert guidelines strongly recommend epidural injections, citing their long-term effectiveness in treating chronic spinal pain. A review found that epidural corticosteroid injections may reduce leg pain in patients with lumbosacral radicular pain. In this case, the patient has a history of radiculopathy …”
“Nature of Statutory Criteria/Case Summary: The patient has requested authorization and coverage for lumbar epidural steroid injections. The American Society of Interventional Pain Physicians (ASIPP) guidelines for epidural interventions in the management of chronic spine pain note that there is Level I evidence, with strong recommendations, for caudal, interlaminar, and transforaminal procedures for chronic low back and/or lower extremity pain …”

Cervicalgia is defined as the presence of pain in the neck region that may radiate to the shoulders, upper limbs, or back.

- 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 Epidural Injection denials for CNS/ Neuromusc Dis overturned?
In 5 California IMR decisions from 2015 to 2025, reviewers overturned 4 (80.0%). In the last five years: 100.0% of 3. 4 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.
