CPT® Code 99406 is used to report intermediate smoking and tobacco use cessation counseling provided to a patient for 3 to 10 minutes. This service involves counseling patients on quitting tobacco use, discussing health risks, and developing strategies to support cessation. It may be provided during a preventive visit or alongside another Evaluation and Management (E/M) service when medically appropriate.
When billed on the same day as a separately identifiable E/M service, modifier -25 should be appended to the E/M code.
