What G0538 covers
G0538 represents monthly ASCVD risk-management work performed by clinical staff, rather than the risk calculation itself. The service is relevant when a practice is addressing a patient’s cardiovascular risk through ongoing clinical support, such as follow-through on risk-reduction planning and communication with the care team. It is distinct from a one-time ASCVD risk assessment and is not a code for a particular test or procedure.
Report the code for the month in which the staff management service occurs. The record should identify the patient’s ASCVD-related risk-management needs and document the staff work performed during the month, including relevant follow-up or care coordination. Keep this monthly service separate in the record from an ASCVD risk assessment or other counseling and care-management services performed for the patient. The CMS rules supplied for this code list no special payment provisions.

G0538 billing questions
How is G0538 different from G0537?
G0538 describes monthly ASCVD risk-management services by clinical staff. G0537 is the ASCVD risk-assessment service, described as occurring once per 12 months.
Is G0538 reported for each staff contact?
The code is defined per month, not per contact. Document the management work provided during the month rather than treating each call or touchpoint as a separate monthly unit.
What documentation supports G0538?
Record the patient’s ASCVD risk-management needs and the clinical staff activities performed during the month, including relevant follow-up and care-team communication.
Can an ASCVD risk assessment and monthly management both be documented?
Yes, they describe different work: G0537 is risk assessment, while G0538 is monthly management. Document each service distinctly when both are provided.
Does G0538 describe a cardiovascular test?
No. It describes clinical staff management services; G0537 is the related code for ASCVD risk assessment.
