creating a bypass mechanism for health insurer step therapy protocols when medically necessary.

HB 1638 creates a process for healthcare providers to bypass step therapy protocols when a patient's condition requires it, directly affecting patients and providers in insurance plans that use step therapy. Step therapy typically forces patients to try less expensive medications first before coverage is provided for more expensive alternatives. The bill requires step therapy protocols to be based on updated clinical guidelines developed by expert panels and mandates that insurers must grant an override request when providers demonstrate medical necessity, including conditions like advanced cancer or serious mental illness. This establishes a clear, evidence-based pathway to avoid unnecessary treatment delays without altering existing insurance coverage rules.
