G0 Modifier Required for Telehealth for Individuals with Acute Stroke

Effective for claims with dates of service on and after 1/1/2019, Medicare will accept HCPCS modifier G0 to identify telehealth services furnished for purposes of diagnosis, evaluation, or treatment of symptoms of an acute stroke. Acute stroke telehealth services can be furnished in any hospital, critical access hospital, mobile stroke units (as defined by the Secretary), or any other site determined appropriate by the Secretary, in addition to the current eligible telehealth originating sites. Note that section 1834(m)(4)(C) of the Social Security Act limits payment of an originating site facility fee for acute stroke telehealth services furnished in sites that meet the usual telehealth restrictions under section 1834(m)(4)(C) of the Social Security Act.

Modifier G0 is valid for all telehealth distant site codes billed with POS code 02 or critical access hospitals, CAH method II (revenue codes 096X, 097X or 098X) or telehealth originating site facility fee billed with HCPCS code Q3014.
