CPT® Code 26410

Injuries to the extensor tendons of the hand can manifest as partial or complete lacerations, tears, or ruptures. These injuries often necessitate surgical intervention to restore function and integrity to the tendon. The procedure described by CPT® Code 26410 involves the repair of the extensor tendon in the hand, which can be categorized as either a primary or secondary repair. A primary repair is typically conducted within 24 hours following the injury, allowing for optimal healing conditions. However, in cases where the wound is grossly contaminated, the primary repair may be postponed for up to two weeks to ensure a cleaner surgical environment. Conversely, a secondary repair is defined as one that is performed more than two weeks after the initial injury, often due to complications or delayed presentation. The surgical approach involves exposing the tendon through a dorsal incision, with careful dissection of the surrounding soft tissues to protect vital neurovascular structures. Once the tendon is accessed, the surgeon locates the distal and proximal ends of the severed tendon, which may require additional incisions if the proximal end has retracted beyond the reach of the initial incision. The procedure culminates in the approximation and suturing of the tendon ends, effectively restoring continuity and function. This code is specifically utilized for each tendon that is repaired without the use of a free graft, distinguishing it from related procedures that may involve grafting techniques.
