The expansion of telehealth during the COVID-19 pandemic has been lightning fast, particularly compared to its slow trajectory before the crisis. The Lancet first discussed how phone-based doctor appointments could reduce the need for in-person visits in 1879. Science and Invention foresaw video-based telehealth encounters in 1925. However, prior to COVID-19, less than 10 percent of the U.S. population used telehealth for a clinical encounter, and only 18 percent of physicians provided such services.
The slow rate of adoption is not due to a lack of evidence. On the contrary, telemental health (i.e., the provision of mental and behavioral health services via technology), in particular, has a robust evidence base. Numerous studies have demonstrated its effectiveness across a range of modalities (e.g., telephone, videoconference) and mental health concerns (e.g., depression, substance use disorders).
Virtual services are safe, effective, and comparable in outcomes to in-person services. However, prior to COVID-19, telemental health was used primarily to provide services in areas that otherwise do not have access — for instance, in rural regions. It is now used throughout the country.
Barriers to Telehealth
One of the largest barriers to widespread implementation of telemental health has been issues of parity. No federal statute requires payers to reimburse telehealth encounters at the same rate as in-person (i.e., reimbursement parity) or even to cover telehealth at all (i.e., coverage parity). State parity laws are thus essential to guarantee that providers will receive comparable payment for telehealth encounters as for in-person services. But prior to COVID-19, only five states had implemented telehealth parity laws. And while recent analyses showed that an additional 21 states expanded telehealth services through COVID-19 emergency orders, only 13 required parity. Many states have taken direct action via Medicaid policy; all but two issued specific guidance on the expansion or reimbursement of Medicaid-based telehealth services.
