CPT® Code 25442

The procedure described by CPT® Code 25442 refers to an arthroplasty involving the prosthetic replacement of the distal ulna, which is a surgical intervention aimed at addressing conditions affecting the distal ulna, often due to trauma, arthritis, or other degenerative diseases. The distal ulna is the end portion of the ulna bone located near the wrist, and its replacement is typically indicated when the bone is severely damaged or diseased. The surgery involves making an incision along the posterior aspect of the wrist, allowing access to the radiocarpal joint and the distal radioulnar joint (DRUJ). During the procedure, careful attention is given to protect the surrounding nerves and tendons, ensuring that the surgical field is clear for the replacement of the distal ulna with a prosthetic component. This intervention aims to restore function and alleviate pain in the wrist, ultimately improving the patient's quality of life. The procedure is performed under sterile conditions, and the surgical team follows strict protocols to ensure the best possible outcomes for the patient.
