Nondisp commnt fx shaft of ulna, unsp arm, 7thE

This code describes a fracture of the ulna bone in the forearm that is broken into multiple pieces (comminuted) but remains in its normal anatomical position (nondisplaced). The fracture involves the shaft of the ulna, and the specific arm is not documented. This code is used for follow-up care of an open fracture (where the skin was broken) of Type I or II, indicating routine healing is occurring.

This code is appropriate for subsequent encounters when a patient is receiving ongoing treatment for a previously diagnosed nondisplaced comminuted ulnar shaft fracture that was initially an open fracture type I or II and is now healing without complications. This would include follow-up appointments for cast changes, wound checks, or physical therapy during the routine healing phase.

• Ensure documentation specifies "nondisplaced" and "comminuted" for the ulnar shaft fracture.
• Confirm the initial injury was an open fracture type I or II and that the current encounter is for routine healing.
• Do not use this code for initial treatment or for fractures with delayed union, nonunion, or malunion.
