Anesthesia Coding Practice Test 2026 - Free Anesthesia Coding Practice Questions and Study Guide

Understanding how to code anesthesia services hinges on pairing the correct base code for the surgical procedure with an ASA status modifier that reflects the patient’s systemic condition. Reduction mammoplasty has a specific anesthesia base code, and a patient with mild hypertension falls into ASA Physical Status II, which is indicated with the -P2 modifier. Therefore the combination 00402-P2 accurately codes the service: the base code covers anesthesia for reduction mammoplasty, and the -P2 notes mild systemic disease. The other options don’t fit because they either use a base code not aligned with the breast reduction procedure or apply an ASA modifier that doesn’t match the patient’s mild hypertension (healthy or more severe disease), so they would not reflect the correct service or patient status.
