(a) Subject to Subsections (b) and (c), a volunteer health practitioner shall adhere to the scope of practice for a similarly licensed practitioner established by the licensing provisions or other laws of this state.
(b) Except as otherwise provided by Subsection (c), this chapter does not authorize a volunteer health practitioner to provide a service that is outside the practitioner’s scope of practice, even if a similarly licensed practitioner in this state would be permitted to provide the service.

(c) The division may modify or restrict the health or veterinary services that a volunteer health practitioner may provide under this chapter. An order under this subsection may take effect immediately, without prior notice or comment, and is not a rule within the meaning of Chapter 2001, Government Code.
(d) A host entity may restrict the health or veterinary services that a volunteer health practitioner may provide under this chapter.
(e) A volunteer health practitioner does not engage in unauthorized practice unless the practitioner has reason to know of any limitation, modification, or restriction under this section or that a similarly licensed practitioner in this state would not be permitted to provide the service. A volunteer health practitioner has reason to know of a limitation, modification, or restriction or that a similarly licensed practitioner in this state would not be permitted to provide a service if:
(1) the practitioner knows the limitation, modification, or restriction exists or that a similarly licensed practitioner in this state would not be permitted to provide the service; or
(2) from all the facts and circumstances known to the practitioner at the relevant time, a reasonable person would conclude that the limitation, modification, or restriction exists or that a similarly licensed practitioner in this state would not be permitted to provide the service.
(f) In addition to the authority granted by the law of this state other than this chapter to regulate the conduct of health practitioners, a licensing board or other disciplinary authority in this state:
(1) may impose administrative sanctions on a health practitioner licensed in this state for conduct outside of this state in response to an out-of-state emergency;
(2) may impose administrative sanctions on a practitioner not licensed in this state for conduct in this state in response to an in-state emergency; and
(3) shall report any administrative sanction imposed on a practitioner licensed in another state to the appropriate licensing board or other disciplinary authority in any other state in which the practitioner is known to be licensed.
(g) In determining whether to impose an administrative sanction under Subsection (f), a licensing board or other disciplinary authority shall consider the circumstances in which the conduct took place, including any exigent circumstances, and the practitioner’s scope of practice, education, training, experience, and specialized skill.
