The Telehealth Response for E-prescribing Addiction Therapy Services Act, or TREATS Act, aims to expand access to substance use disorder treatment by modifying the Controlled Substances Act. This legislation introduces the option for a telehealth evaluation as an alternative to an in-person medical evaluation for prescribing certain controlled substances. Specifically, for Schedule III, IV, or V controlled substances approved by the Food and Drug Administration for substance use disorder treatment, a telehealth evaluation can now fulfill the initial assessment requirement. The bill defines a telehealth evaluation as a real-time, two-way interactive medical assessment conducted remotely by a practitioner using audio-only or audio and video telecommunications, adhering to all applicable Federal and State laws.
