CPT® Code 26502

The procedure described by CPT® Code 26502 involves the reconstruction of a tendon pulley, specifically utilizing a tendon or fascial graft. This procedure is categorized as a separate procedure, which means it is performed independently and is not part of a more comprehensive surgical intervention. The tendon pulley system is essential for the proper flexion of the fingers, consisting of a series of annular and cruciate pulleys that facilitate the movement of tendons. In the fingers, the second annular (A2) and fourth annular (A4) pulleys are particularly crucial, while the thumb relies on the oblique pulley for its flexion capabilities. When a critical pulley sustains an injury, the ability to flex the finger is significantly impaired unless surgical reconstruction is performed. The reconstruction process may involve the use of local tissue, such as the flexor digitorum superficialis (FDS), or a graft harvested from another site, typically the forearm or leg. The procedure entails exposing the damaged pulley, excising any compromised tissue, and securing the graft to reconstruct the pulley structure. This meticulous approach ensures that the pulley is restored to its functional state, allowing for improved range of motion and finger dexterity post-surgery.
