Physicians who treat and prescribe through communications technology are practicing medicine and must possess a full Texas medical license when treating residents of Texas. An out-of-state physician may provide episodic consultations without a Texas medical license, as provided in Texas Occupations Code, §151.056, §172.2(g)(4) of this title (relating to Construction and Definitions), and §172.12(f) of this title (relating to Out-of-State Telemedicine License).
