AHA Coding Clinic® for ICD-9 - 1996 Second Quarter
Cartilage Transposition
Cartilage transposition is a new procedure that is being performed more widely in the United States. The procedure is intended for the treatment and repair of clinically significant articular cartilage defects of the knee. Cartilage transposition is performed in two stages. In the first stage, under general anesthesia, a videoarthroscopy is performed and the articular defect is identified, examined, and all damaged cartilage is debrided. The debrided defect is carefully measured, the size recorded, and the defect photographed. A small portion of healthy articular cartilage tissue is harvested from a minor weight bearing area of the affected knee for...

Article Overview
This article explains a staged cartilage transplantation technique used for knee articular cartilage repair, including the general surgical workflow, tissue harvesting, laboratory cell preparation, implantation, and postoperative rehabilitation. It is written for medical coders and coding professionals who need to understand the procedure context and the related ICD-9-CM coding discussion.
Why This Topic Matters
Understanding how this staged knee cartilage repair is performed helps coders interpret operative documentation and match the procedure to the correct ICD-9-CM coding framework referenced by the article.
