What the insurer actually argued
Denials fall into different categories, and they don’t succeed equally — so the reason on your letter changes how you should answer it.
| Reason given | Decisions | Overturned |
|---|---|---|
Medical Necessity The plan said the care wasn’t medically necessary. The most common fight, and the most winnable. | 88 | 27.3% |
Experimental/Investigational The plan called the treatment unproven. These turn on published evidence, so the appeal is a literature argument. | 70 | 24.3% |
Urgent Care Expedited reviews, decided in days rather than weeks. | 5 | 40% |

What the reviewers wrote
Excerpts from the independent reviewers’ published findings — the actual reasoning, quoted, not summarised.
Where the denial was overturned
Physician 1: The patient is a 57-year-old man with a lesion in the talus. A request has been made for an osteochondral allograft transfer system (OATS) procedure. The Health Plan has denied authorization for the proposed procedure on the basis it is considered investigational for repair of an ankle joint.The OATS procedure has been very successful in the knee and recently has been utilized in the ankle for situations such as these. There are no other options for the patient; the procedure is likely to provide pain relief and help to prevent the need for fusion. Therefore, I have determined that the requested procedure is likely to be more beneficial for treatment of the patient’s medical condition than any available standard therapy.
Nature of Statutory Criteria/Case Summary: An enrollee has requested authorization and coverage for sacroiliac joint fusion surgery for treatment of the enrollee who has a history of low back pain. Findings: 2/3 of the physician reviewers found that Sacroiliac fusion is used to immobilize the diseased joint that transmits weight from the spine to the pelvis. The medical evidence indicates that prevention of motion is the only treatment that durably alleviates the pain in the affected sacroiliac joint when non-operative therapies have failed. The recommended sacroiliac joint fusion surgery is in accordance with guidelines and policy statements of major societies.
Where the denial was upheld
Worth reading too — these show what an appeal has to overcome.
Physician 1: The patient is a 38-year-old female with a long-standing history of hip pain. She has been diagnosed with osteoarthritis. The patient’s physician recommended metal-on-metal hip surfacing, which the Health Plan has denied due to a lack of scientific evidence in peer-reviewed medical literature to support its efficacy.Metal-on-metal hip resurfacing is still in experimental/investigational studies. Short-term data is sparse, with no long-term prospective study establishing its effectiveness. In addition, the procedure’s risks are uncertain. Furthermore, there are other treatments available for this patient. At this time, metal-on-metal hip resurfacing cannot be recommended as there is very little data to warrant its general use.
Physician 1The patient is a 24-year-old active woman status post four lateral arthroscopic knee procedures following an initial bucket handle tear first treated with meniscal repair. She has documented early chondral changes, and continues to be symptomatic. There is no apparent injury to the anterior cruciate ligament (ACL), nor does there seem to be concern regarding any angular deformity. She has been deemed a candidate for meniscal allograft transplantation (MAT), with apparent concurrence from more than one physician. The Health Plan has denied authorization for the requested procedure on the basis that it is considered experimental. The patient has demonstrated repeated injury requiring surgery following her initial failed meniscal repair. She has early chondral changes now requiring microfracture/drilling for reconstruction.
Figures and quotations on this page come from 42,749 published decisions in the California DMHC Independent Medical Review dataset. These are California outcomes — every state runs an equivalent external review, but the rates here are California’s. Excerpts are quoted verbatim from the public record and describe this condition generally, not any individual case.
How to use this in your appeal
These outcomes come from California’s external review program — an independent physician panel whose decision binds the insurer. Every state has an equivalent, and internal appeals succeed even more often. If your care for joint problem was denied, the published record says the denial is worth fighting.
