What G0397 covers

G0397 describes a structured assessment and intervention for alcohol or other substance use, excluding tobacco. The encounter may include reviewing a screening result, discussing health and safety risks, providing motivational feedback and advice about reducing or stopping use, and planning a treatment referral when indicated. It is used for focused clinician-patient encounters in settings such as primary care and outpatient care.

Choose G0397 when the documented time for the structured assessment and intervention exceeds 30 minutes; 15 through 30 minutes is reported with G0396. Document the assessment findings, intervention provided, time spent on this service, the patient’s response, and any referral or follow-up plan. The time should reflect the assessment and intervention rather than unrelated evaluation or routine counseling.

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.

G0397 billing questions

How does G0397 differ from G0396?

G0397 is for a structured alcohol or non-tobacco substance-use assessment and intervention lasting more than 30 minutes. G0396 is used when the service lasts 15 through 30 minutes.

Does G0397 include tobacco counseling?

No. G0397 covers alcohol or other substance use, excluding tobacco.

Can a screening alone support G0397?

A screening alone does not describe the structured assessment and intervention represented by G0397. Documentation should show the intervention delivered and the time spent on the service.

What time should the record support?

Document the time spent on the structured assessment and intervention, and show that it exceeds 30 minutes. Do not include unrelated evaluation or routine counseling time in that total.

How does G0397 differ from G0443?

G0443 describes brief counseling for alcohol misuse. G0397 represents a longer structured assessment and intervention and can address substances other than alcohol, excluding tobacco.

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.
