Disp fx of capitate bone, left wrist, subs for fx w nonunion

This code signifies a displaced fracture of the capitate bone, located in the left wrist, that has failed to heal properly after an initial treatment. The "nonunion" indicates that the bone fragments have not joined together to form a solid bone, despite the expected healing period. This condition often leads to persistent pain, instability, and functional impairment of the wrist.

Apply this code when a patient presents for follow-up care of a previously treated left capitate fracture that is now confirmed to have nonunion. This includes scenarios where the patient is undergoing further evaluation, receiving treatment for the nonunion (e.g., bone grafting, revision surgery), or managing complications related to the unhealed fracture.

• Ensure documentation clearly specifies "nonunion" and the left wrist.
• Verify that the encounter is for subsequent care, not the initial treatment of the fracture.
• Always assign additional codes for any associated complications or treatment procedures.
