Nondisp commnt fx shaft of ulna, l arm, 7thN

This code describes a left ulnar shaft fracture that is broken into multiple pieces but remains in its anatomical position. It specifically indicates an open fracture (where the bone broke through the skin) of a severe nature (Type IIIA, IIIB, or IIIC) that has failed to heal properly after initial treatment.

Apply this code for a patient presenting for follow-up care of a left ulnar shaft fracture that was initially an open fracture and is now complicated by nonunion. This would be used during subsequent encounters after the initial treatment of the fracture. This code is appropriate when documentation confirms the comminuted nature and nondisplaced alignment of the fracture.

• Ensure documentation specifies "left arm" and "ulna shaft" to differentiate from other forearm fractures.
• Verify the fracture is explicitly documented as "nondisplaced" and "comminuted."
• Confirm the original injury was an "open fracture type IIIA, IIIB, or IIIC" and that "nonunion" is present.
