Reader Question:

Arthroscopic Surgery

Question: If a diagnostic arthroscopy (29870) is done on the medial compartment of the knee, and a surgical arthroscopy with a meniscectomy is done on the lateral compartment (29881), is 29870 separately billable with a modifier -59 (distinct procedural service) because it is done on a different compartment from 29881?

New Jersey Subscriber

Answer: The instructional notes at the beginning of the Endoscopy/Arthroscopy subsection of CPT state that surgical arthroscopy always includes a diagnostic arthroscopy. Therefore, whenever an arthroscopic surgical procedure is performed on the knee, a diagnostic arthroscopy of the knee is included, regardless of the compartments of the knee involved, and 29870 should not be reported.
