Telemental Health Care Access Act of 2021 This bill eliminates certain restrictions relating to Medicare coverage of mental health services that are provided through telehealth. Current law allows for coverage of such services regardless of the geographic location of the originating site (i.e., the location of the beneficiary) after the end of the COVID-19 public health emergency, as long as the beneficiary previously received in-person services and continues to receive in-person services at specified intervals. The bill eliminates these in-person requirements.
