What G0396 covers
G0396 covers a structured assessment for alcohol or other substance use followed by a brief intervention, with 15–30 minutes spent on the service. A clinician may use an instrument such as AUDIT for alcohol or DAST for drug use, discuss the findings, advise behavior change, and arrange treatment referral when indicated. The service involves more than administering a questionnaire; it includes assessment and a responsive intervention.
Select G0396 based on the documented assessment, intervention, and time, not solely on a substance-use diagnosis or screening result. Record the instrument or assessment method, findings, counseling provided, total service time, and any referral or follow-up plan. Use G0397 when the documented service exceeds 30 minutes. CMS assigns work, practice expense, and malpractice relative values to G0396 in the physician fee schedule, with practice-expense values differing by office and facility setting.
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.

G0396 billing questions
When should G0396 be used instead of G0397?
Use G0396 for a documented structured assessment and brief intervention lasting 15–30 minutes. G0397 is the longer-duration counterpart for services exceeding 30 minutes.
Does administering a screening questionnaire alone support G0396?
No. G0396 includes a brief intervention after the structured assessment; document the discussion or counseling that followed the assessment.
What documentation should support G0396?
Record the assessment method or instrument, results, intervention provided, total service time, and any referral or follow-up plan.
Can the same counseling time be counted toward an office visit and G0396?
Do not count the same work or time twice. Document the substance-use assessment and intervention distinctly from any separately reported evaluation and management service.
How many units of G0396 are reported for a 15–30-minute service?
G0396 represents the 15–30-minute service. Document the total time supporting that service; use G0397 when the service exceeds 30 minutes.
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.
