Telemedicine Codes

Telemedicine and telehealth are used interchangeably throughout the United States healthcare system, in reference to the exchange of medical information from one site to another through electronic communication. Reporting of telemedicine/telehealth services varies by payer and state regulations.

CPT Telemedicine Codes

Modifier 95 indicates a synchronous telemedicine service rendered via a real-time interactive audio and video telecommunications system. The 2020 CPT® manual includes Appendix P, which lists a summary of CPT codes that may be used for reporting synchronous (real-time) telemedicine services when appended by modifier 95. Procedures on this list involve electronic communication using interactive telecommunications equipment that includes, at a minimum, audio and video.

HCPCS LEVEL II CODES

There are also HCPCS Level II codes that describe telemedicine services.

HCPCS Level II Telehealth Codes Type of Service New Patient Established Patient
G0406-G0408 Follow-up Inpatient Consultation via Telehealth X
G0425-G0427 Telehealth Consultation, Emergency Department X
G0508, G0509 Telehealth Consultation, Critical Care X X

Place of Service (POS) Code for Telemedicine

On January 1, 2017 the Center for Medicare and Medicaid Services (CMS) introduced place of service (POS) code 02 to identify telemedicine services. The descriptor for POS code 02 is “The location where health services and health related services are provided or received, through telecommunication technology.” Use of the telehealth POS code certifies that the service meets all of the telehealth requirements. Many private payers have also begun requiring use of POS code 02 for telemedicine services.

GT/GQ Modifiers

Medicare previously required providers to submit claims for telehealth services using the appropriate procedure code along with the telehealth GT modifier (“via interactive audio and video telecommunications systems”) or GQ modifier (“via an asynchronous (delayed communications) telecommunications system”). As of January 1, 2018, the GT modifier is only allowed on institutional claims billed under Critical Access Hospital (CAH) Method II since institutional claims do not use a POS code. If the GT modifier is billed by other provider types, the claim line will be rejected. The GQ modifier is still required when applicable (e.g., for those providers participating in the Alaska or Hawaii federal telemedicine demonstration programs).
