Texas Medical Disclosure Panel

The TMDP was established by the 65th Legislature in 1977. The panel is appointed by the Executive Commissioner and comprises nine members; three members licensed to practice law in Texas and six members licensed to practice medicine in Texas.

The purpose of the TMDP is to determine which risks and hazards related to medical care and surgical procedures must be disclosed by health care providers or physicians to their patients or persons authorized to consent for their patients, and to establish the general form and substance of such disclosure.

The panel identifies and makes a thorough examination of all medical treatments and surgical procedures in which physicians and health care providers may be involved in order to determine which of those treatments and procedures do and do not require disclosure of the risks and hazards to the patients or persons authorized to consent for the patients.

Staff Responsibility

Regulatory Services Operations Support is responsible for supporting the TMDP. The panel meets at the call of the Chairman or on petition of at least three members of the panel, usually three to four times annually.

The TMDP has created two separate lists, List A and B, of medical treatments and surgical procedures that do and do not require disclosure. The TMDP has also developed Disclosure and Consent Forms (see below), on which the disclosure will be made.

Please note: Effective Dec. 26, 2023, in order to make these lists more accessible to the public and more user-friendly, the TMDP repealed and replaced certain portions of the Texas Administrative Code (TAC), as listed below.


  • repealed 25 TAC Chapter 601, concerning Informed Consent;
  • adopted new 25 TAC Chapter 601, concerning General;
  • adopted new 25 TAC Chapter 602, concerning Procedures Requiring Full Disclosure of Specific Risks and Hazards--List A;
  • adopted new 25 TAC Chapter 603, concerning Procedures Requiring No Disclosure Of Specific Risks And Hazards--List B;
  • adopted new 25 TAC Chapter 604, concerning Disclosure Forms.
