What G0508 covers

A remote critical-care physician uses telehealth to assess and manage a critically ill or injured patient, often in an ICU or emergency department. The consultation may address acute problems such as respiratory failure or shock and coordinate treatment with the bedside team. The service is distinct from a routine video visit: the patient’s condition requires critical-care expertise and management.

Select G0508 for the initial 60-minute telehealth critical-care consultation, not merely because a patient is hospitalized or the clinician connects remotely. Documentation should establish the critical illness, the physician’s assessment and management, the telehealth encounter, and the time attributable to the service. CMS fee-schedule data assign work, practice expense, and malpractice relative values to the code. G0509 identifies the related subsequent 50-minute telehealth critical-care service.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

How the G0508 rate is calculated

G0508 billing questions

When should G0508 be chosen over G0509?

G0508 describes the initial 60-minute telehealth critical-care consultation. G0509 is the related subsequent service with a 50-minute time description.

Can G0508 be used for any video consultation with a hospitalized patient?

No. The encounter must involve critical-care assessment and management for a critically ill or injured patient, rather than a routine inpatient video visit.

What should the note support?

Document the patient’s critical condition, the physician’s telehealth assessment and management, and the time spent on the critical-care consultation.

Should 99291 also be reported for the same telehealth work?

99291 is the conventional critical-care service code, not the telehealth consultation code. Do not report both simply to represent the same 60 minutes of work.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
