Foundation One denials in California external review
In the California DMHC record, independent physician reviewers decided 20 published external-review cases involving Foundation Oneand overturned the plan’s denial in 25%. That is a historical result among cases that reached this program, not a forecast for an individual appeal.
What the reviewers wrote
Where the denial was overturned
Nature of Statutory Criteria/Case Summary: A female enrollee has requested reimbursement for the gene testing (Foundation One) for evaluation of the enrollee’s oligodendroglioma. Findings: The physician reviewer found that Foundation One testing offers a comprehensive panel of molecular genetic markers on an individual’s tumor with the hopes of identifying markers than can help guide therapy decision making. The National Comprehensive Cancer Network (NCCN) guidelines have not determined that molecular markers are useful in treatment determination (predictive markers) and prognosis other than codeletion of 1p and 19q, isocitrate dehydrogenase 1 and 2 (IDH1 and IDH2) mutation, and MGMT promoter methylation. There is currently a phase II clinical trial underway that is evaluating the efficacy of genetic molecular testing to guide individual therapy.
Nature of Statutory Criteria/Case Summary: An enrollee has requested reimbursement for the genetic testing called Foundation One for the evaluation of her recurrent metastatic clear cell uterine cancer. Findings: Two physician reviewers found that there is sufficient support for the services at issue in this clinical setting. Adenocarcinoma of the endometrium (lining of the uterus) is the most common type of uterine cancer. This patient’s pathology was consistent with a serous-clear cell morphology. Serous is the second most common histology of endometrial cancer whereas clear cell is uncommon. Both of these histologic types are associated with a worse prognosis and frequently present with extrauterine disease at the time of diagnosis.
Where the denial was upheld
Nature of Statutory Criteria/Case Summary: An enrollee has requested reimbursement for the genomic analysis for evaluation of the enrollee’s recurrent breast cancer. Findings: 2/3 of the physician reviewers found that there is a lack of support in the medical literature for the services at issue in this clinical setting. FoundationOne is a molecular assay that explores the mutations of an individual’s cancer cells. The hope is that the assay will identify a specific mutation or target, which could inform the clinician as to which chemotherapeutic drug would be useful. However, there is a lack of convincing evidence that the assay adds to the decision making ability of the clinician, nor yields a result that is reliably clinically beneficial.
Nature of Statutory Criteria/Case Summary: The patient has requested reimbursement for the gene test (Foundation One) for evaluation of the enrollee’s head and neck squamous cell carcinoma. Findings: The physician reviewer found that Foundation One is a molecular assay that explores the mutations of an individual patient’s cancer cells. The goal of the assay is to identify a specific mutation or target which could guide the provider as to which chemotherapeutic agent would be useful. However, there is a paucity of evidence that the Foundation One assay adds to decision making ability, or yields a result that is reliably clinically beneficial. There are non-randomized studies exploring the value of molecular profiling, but the results have not been convincing as to the efficacy of such an approach to treatment (Von Hoff, et al).
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 treatment 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 Foundation One, then check the rights and deadlines that apply to your plan.
