(a) In this section, “nonelective medical procedure” means a medical procedure, including a surgery, a physical exam, a diagnostic test, a screening, the performance of a laboratory test, and the collection of a specimen to perform a laboratory test, that if not performed within a reasonable time may, as determined in good faith by a patient’s physician, result in:
(1) the patient’s loss of life; or
(2) a deterioration, complication, or progression of the patient’s current or potential medical condition or disorder, including a physical condition or mental disorder.
(b) The Texas Medical Board during a declared state of disaster may not issue an order or adopt a regulation that limits or prohibits a nonelective medical procedure.

(c) The Texas Medical Board during a declared state of disaster may issue an order or adopt a regulation imposing a temporary limitation or prohibition on a medical procedure other than a nonelective medical procedure only if the limitation or prohibition is reasonably necessary to conserve resources for nonelective medical procedures or resources needed for disaster response. An order issued or regulation adopted under this subsection may not continue for more than 15 days unless renewed by the board.
(d) A person subject to an order issued or regulation adopted under this section who in good faith acts or fails to act in accordance with that order or regulation is not civilly or criminally liable and is not subject to disciplinary action for that act or failure to act.
(e) The immunity provided by Subsection (d) is in addition to any other immunity or limitation of liability provided by law.
(f) Notwithstanding any other law, this section does not create a civil, criminal, or administrative cause of action or liability or create a standard of care, obligation, or duty that provides the basis for a cause of action for an act or omission under this section.
