Is G0509 covered for telehealth? (Medicare)
G0509 (critical care telehealth consultation, 50 minutes) appears on Medicare's list of approved telehealth services, meaning it can be furnished remotely to Medicare beneficiaries when program requirements are met. Current status shown here is Covered, but coverage rules can change and should be verified for each date of service.
How to bill it
Bill G0509 with the place-of-service code matching where the patient was located: POS 02 if the patient was not at home, or POS 10 if the patient was at home. Append modifier 95 to indicate the service was furnished via a synchronous audio-video telehealth interaction. POS reference → · modifier reference →
Audio-only
Medicare's list of telehealth services doesn't specify audio-only eligibility for this code. Audio-only is permitted for a number of services (notably behavioral and mental-health care); confirm against current CMS guidance and your payer before billing audio-only.
Frequently asked
What's the difference between POS 02 and POS 10 for G0509?
POS 02 is used when the patient is located somewhere other than home for the telehealth service, while POS 10 indicates the patient was at home. The correct POS depends on the patient's actual location at the time of the encounter, not the provider's location.
Does modifier 95 apply the same way for commercial payers?
This reference reflects Medicare rules. Commercial and Medicaid payers often have their own telehealth POS, modifier, and covered-code requirements that can differ from Medicare, so check each payer's policy before billing G0509.
Can G0509 be billed for an audio-only critical care consult?
Audio-only status isn't specified for G0509 in the source Medicare telehealth list. Verify directly with CMS or the payer whether an audio-only encounter meets requirements for this code before submitting the claim.
