Displ commnt fx shaft of ulna, r arm, 7thK

This code signifies a complex break in the main part of the right ulna bone, where the bone has shattered into multiple fragments and is out of its normal alignment. This specific code is used when the patient is receiving follow-up care for this fracture, and the bone fragments have not healed together as expected (nonunion), but the skin over the fracture site remains intact.

Apply this code for subsequent encounters when a patient with a previously diagnosed displaced comminuted fracture of the right ulnar shaft is being treated for nonunion, and the fracture is closed. This includes situations where the patient is undergoing further evaluation, conservative management, or surgical intervention for the nonunion.

• Ensure documentation clearly states "nonunion" and that the fracture is "closed."
• Verify laterality (right arm) and the specific bone (ulna shaft) are accurately documented.
• Confirm this is a subsequent encounter, not the initial treatment for the fracture.
