Emergency COVID Telehealth Response Act This bill requires the Centers for Medicare & Medicaid Services (CMS) to allow, when exercising its waiver authority, the following providers to furnish telehealth services under Medicare during the public health emergency relating to COVID-19 (i.e., coronavirus disease 2019): physical therapists, physical therapist assistants, occupational therapists, occupational therapy assistants, speech-language pathologists, clinical social workers, and audiologists. (Currently, the CMS is authorized to waive requirements for Medicare telehealth services during the public health emergency, and it has done so to allow all providers that are otherwise eligible to furnish in-person services under Medicare to also furnish telehealth services.)
