Which code corresponds to anesthesia for left ankle arthroscopy?

• A. 00142-P2
• B. 01464-P1
• C. 00731-P1
• D. 01958-P1

Answer: (B)

The key idea is matching the anesthesia CPT code to the surgical site of the procedure. Ankle arthroscopy is a lower-extremity procedure, so the anesthesia code should come from the group that covers anesthesia for procedures on the lower leg, ankle, and foot. The code 01464 is the designation used for anesthesia in that region, and the trailing modifier P1 reflects the patient’s ASA physical status (a healthy patient). Therefore, 01464-P1 correctly represents anesthesia for a left ankle arthroscopy.

Other codes in the set correspond to anesthesia for different anatomical areas, such as the head/neck region or other joints, which is why they aren’t appropriate for a left ankle arthroscopy. The left side detail is captured by the operative report in terms of site, while the anesthesia code focuses on the region involved.
