Can agencies reject treating physicians' testimony without explanation? Intermountain Healthcare v. OptumHealth Explained

In Intermountain Healthcare v. OptumHealth, the Utah Court of Appeals addressed when administrative agencies must defer to treating physicians’ medical judgments in Medicaid reimbursement disputes.

Background and Facts

A Medicaid patient was involuntarily committed for inpatient psychiatric care following a suicide attempt from March 31 to April 17, 2013. OptumHealth, which pays mental health providers for Salt Lake County Medicaid patients, determined that treatment after April 1 was not medically necessary under established guidelines. An administrative law judge recommended payment for only three days, finding the patient no longer posed an “imminent risk of harm” after April 1, despite the treating physician’s testimony that continued care was necessary.

Key Legal Issues

The case presented two critical issues: whether the ALJ properly interpreted the Medicaid guidelines defining medical necessity for acute inpatient psychiatric care, and whether the ALJ could reject the treating physician’s testimony without providing a reasoned basis for doing so.

Court’s Analysis and Holding

The Court of Appeals found the ALJ abused her discretion in two ways. First, the ALJ misinterpreted the guidelines by requiring “active suicidal ideation for the entire stay,” when the guidelines actually provided broader criteria including passive suicidal ideation and other risk factors. Second, the ALJ failed to provide a reasoned basis for rejecting the treating physician’s testimony that the patient’s passive suicidal ideation and mood swings justified continued inpatient care. The court emphasized that Medicaid agencies should recognize a “presumption in favor of the medical judgment of the attending physician.”

Practice Implications

This decision reinforces that administrative agencies cannot arbitrarily reject treating physicians’ opinions in favor of reviewing physicians who had limited patient contact. When challenging agency determinations of medical necessity, practitioners should emphasize the treating physician’s direct knowledge and require agencies to articulate specific reasons for any departure from that medical judgment. The decision also demonstrates the importance of carefully analyzing the plain language of administrative guidelines rather than applying overly restrictive interpretations.
