Nationwide Use of Telehealth Among Commercially Insured Individuals 2007–2017.

We assessed telehealth services using the GT modifier (indicating use of an interactive audio and video telecommunication system) to Current Procedural Terminology codes 99201-99205 (new patient visits), 99211-99215 (return patient visits), and 99241-99245 (consultant visits). RESULTS Our sample consisted of 47,911 patients receiving 80,360 telehealth visits between 2007 and 2017 (averaging 1.7 visits per patient). Telehealth use increased from 321 patients and 859 total telehealth visits in 2007 to 14,031 patients and 22,927 visits in 2017 (Table 1). [Extracted from the article]
