HB 3588 establishes a Texas Patients' Bill of Rights, outlining patient rights regarding health care practitioners, informed consent, treatment, and billing. It mandates that patients be informed of a health care provider's qualifications and have the right to request treatment from a physician instead of a nonphysician practitioner. The bill requires health care facilities to provide clear and understandable documentation, including cost estimates and billing details. It also imposes regulations on health care advertising to prevent misleading information about a provider’s qualifications. Violations can result in administrative penalties ranging from $100 to $10,000 per infraction.
