What G0408 covers
G0408 represents a physician’s follow-up consultation with an inpatient through telehealth, at the level typically associated with 35 minutes. A consulting physician, often a specialist who has already evaluated the patient, may review the patient’s interval course, discuss new results, reassess the clinical problem, and provide updated recommendations to the patient and treating team. The service is for follow-up care during an inpatient stay, not the initial telehealth consultation.
Choose G0408 when the documented follow-up service supports this level rather than the shorter G0406 or G0407 levels. The record should show that the encounter was a follow-up, the clinical issues addressed, the physician’s assessment and recommendations, and time supporting the selected level. CMS prices the service under the physician fee schedule. G0408 identifies one follow-up service at this level; it is not a code for separate 35-minute increments.
