How big is the problem?
Research shows most people who receive treatment authorization denials don’t appeal to their health plans; advocates say the fraction who do so often end up being denied yet again by reviewers who are not formally trained in using the decisionmaking criteria required under state law.
Generally speaking, a few doctors, working on behalf of health plans, appear to deny almost every appeal for behavioral health treatment they review, according to data from one medical billing company about treatment facilities around the country.
Regulators don’t have data to track these reviewers’ decisions. Neither the state’s Department of Managed Health Care nor the California Department of Insurance is authorized by state statute to routinely require health plans and health insurers to submit information about how often they deny treatment, nor do they have access to the records of the individual doctors making these denials.
When state regulators do get involved, they overwhelmingly side with patients. For 2023 and the first eight months of 2024, for appeals related to residential treatment denials, the Department of Managed Health Care overturned health plans’ medical necessity decisions a stunning 76% of the time .
