CPT® Code 26498

The CPT® Code 26498 refers to the surgical procedure known as the transfer of tendon to restore intrinsic function in all four fingers. This procedure is indicated for patients experiencing a loss of intrinsic function, which can lead to a condition commonly referred to as claw hand or claw finger. This condition arises from an imbalance between the intrinsic and extrinsic muscles of the hand, resulting in difficulty with finger movement and function. The intrinsic muscles, which are responsible for fine motor control and coordination of the fingers, may become weakened or dysfunctional, leading to the characteristic claw-like appearance of the fingers. The transfer of the flexor digitorum superficialis (FDS) tendon is a surgical intervention aimed at enhancing the intrinsic function of the fingers by substituting for the roles typically performed by the interosseous and lumbrical muscles. This procedure not only alleviates some of the clawing but also improves flexion at the metacarpophalangeal (MCP) joint, thereby restoring better hand function and enhancing the patient's quality of life.
