requiring health care providers to disclose medical services billed to the patient's insurance carrier.

HB 1231 requires health care providers (like hospitals, clinics, and doctors) to give patients a detailed written or electronic statement within 15 business days after billing their insurance. The statement must list each medical service provided, the date, billing codes, amounts billed to insurance, what insurance paid or denied, and any remaining patient balance. This directly affects patients receiving care and providers who must disclose billing details they previously may not have shared. The law aims to increase transparency about insurance claims without changing how providers bill insurers.
