The physician may claim the privilege on the patient's behalf-and is presumed to have authority to do so.
Tex. R. Evid. 509
The former rule's reference to "confidentiality or" and "administrative proceedings" in subdivision (e) [Exceptions in a Civil Case] has been deleted. First, this rule is a privilege rule only. Tex. Occ. Code § 159.004 sets forth exceptions to a physician's duty to maintain confidentiality of patient information outside court and administrative proceedings. Second, by their own terms the rules of evidence govern only proceedings in Texas courts. See Rule 101(b). To the extent the rules apply in administrative proceedings, it is because the Administrative Procedure Act mandates their applicability. Tex. Gov't Code § 2001.083 provides that "[i]n a contested case, a state agency shall give effect to the rules of privilege recognized by law." Section 2001.091 excludes privileged material from discovery in contested administrative cases.
Statutory references in the former rule that are no longer up-to-date have been revised. Finally, reconciling the provisions of Rule 509 with the parts of Tex. Occ. Code ch. 159 that address a physician-patient privilege applicable to court proceedings is beyond the scope of the restyling project.
