Meniscal Tear denials in California external review
In the California DMHC record, independent physician reviewers decided 25 published external-review cases involving meniscal tearand overturned the plan’s denial in 40%. That is a historical result among cases that reached this program, not a forecast for an individual appeal.

What the insurer actually argued
| Reason given | Decisions | Overturned |
|---|---|---|
Medical Necessity The plan said the care wasn’t medically necessary. The most common fight, and the most winnable. | 21 | 38.1% |
Experimental/Investigational The plan called the treatment unproven. These turn on published evidence, so the appeal is a literature argument. | 4 | 50% |
What the reviewers wrote
Where the denial was overturned
Nature of Statutory Criteria/Case Summary: An enrollee has requested authorization and coverage for arthroscopy right knee, debridement/shaving of articular cartilage and meniscectomy. Findings: The physician reviewer found that clinical trials have shown that arthroscopy of the knee is not an effective treatment for osteoarthritis. However, patients who have displaced meniscal tears or loose bodies in a knee with pre-existing arthritis can benefit from this procedure. Arthroscopy can have a role in arthritic knees if there is clinical and imaging evidence of symptomatic meniscal tear causing mechanical symptoms such as painful, disabling catching, locking and popping.
Nature of Statutory Criteria/Case Summary: An enrollee has requested authorization and coverage for collagen meniscus implant of the right knee for treatment of the enrollee’s medical condition. Findings: The physician reviewers found that there is sufficient support for the requested services in this clinical setting. This patient does not have advanced disease that would require a total knee arthroplasty. Individuals who have this procedure are improved because their previous quality of life was significantly limited due to advanced arthritis. For an individual with mild arthritis, however, a total knee arthroplasty would be a poor choice as the kinematics of a knee arthroplasty are poor in relation to a normal knee. However, although this patient does not have advanced arthritis, he continues to be symptomatic.
Where the denial was upheld
Findings: The physician reviewer found that Nature of Statutory Criteria/Case Summary: The parent of a patient has requested authorization and coverage for (1) immediate scheduling of a total knee replacement (TKR) for the right knee, or in the alternative, (2) an arthroscopic procedure for repair of tibia fracture, core decompression of marrow edema, preservation and debridement of anterior cruciate ligament and/or repair of the meniscus, and if so, (3) immediate scheduling of the arthroscopic procedure. The patient is requesting TKR surgery or arthroscopic surgery to be performed urgently with immediate scheduling. However, this is not supported as medically necessary as the patient was recommended to continue conservative measures examination, indicating that these conservative modalities have not been exhausted.
Nature of Statutory Criteria/Case Summary: An enrollee has requested authorization and coverage for electromyography (EMG) of the left shoulder blade muscles (supraspinatus plus infraspinatus muscles), nerve conduction study (NCS) of the left shoulder blade muscles (supraspinatus plus infraspinatus muscles), ultrasound of the left shoulder, and magnetic resonance imaging (MRI) with contrast of the left knee for evaluation of his chronic pain and numbness. Findings: The physician reviewer found that the requested EMG and NCS of the left supraspinatus and infraspinatus muscles are not medically necessary for evaluation of this patient’s medical condition.
Figures and quotations on this page come from 42,749 published decisions in the California DMHC Independent Medical Review dataset. These are California external-review outcomes. Other state and federal programs have different eligibility rules, processes, and current availability; the rates here do not transfer to those programs or predict an individual result. Excerpts are quoted verbatim from the public record and describe this condition generally, not any individual case.
These outcomes describe eligible cases completed through California DMHC’s Independent Medical Review program. They do not estimate the chance that an internal appeal, an external review in another jurisdiction, or your individual case will succeed. Use the record to identify evidence patterns involving meniscal tear, then check the rights and deadlines that apply to your plan.
