HB 473 amends Section 321.002 and related provisions of the Health and Safety Code to improve the communication of patient rights for individuals receiving mental health, chemical dependency, or rehabilitation services. The bill requires the executive commissioner of the Health and Human Services Commission to adopt a comprehensive "patient’s bill of rights" integrating existing statutory rights and other provisions ensuring patient health, safety, and dignity. Facilities must provide written and oral communication of these rights in the patient’s primary language or accommodate disabilities within specific timeframes after admission. Patients or their guardians must sign copies to confirm understanding, which will be included in clinical records. The bill also requires facilities to display the document prominently in public areas, including contact information for lodging complaints, with similar standards applying to involuntary inpatient mental health patients. These provisions take effect on September 1, 2025.
