CPT® Code 25446

The procedure described by CPT® Code 25446 refers to an arthroplasty involving the prosthetic replacement of the distal radius and either partial or complete replacement of the carpal bones, commonly known as a total wrist replacement. This surgical intervention is indicated for patients suffering from severe wrist joint conditions, such as advanced arthritis, trauma, or degenerative diseases that compromise the function and integrity of the wrist. The surgery aims to alleviate pain, restore mobility, and improve the overall quality of life for individuals with debilitating wrist conditions. During the procedure, a midline incision is made on the posterior aspect of the wrist, allowing access to the radiocarpal joint and the distal radioulnar joint (DRUJ). The surgical team meticulously releases the retinaculum and protects the surrounding nerves while resecting the necessary carpal bones and distal radius to accommodate the prosthetic components. The careful placement and stabilization of the prosthesis are crucial for achieving optimal functional outcomes post-surgery.
