Unsp fx shaft of unsp ulna, 7thM

This code signifies a non-healing fracture of the main part of the ulna bone, where the specific location of the break is not documented. It indicates that the initial injury was an open fracture (skin broken) of either Type I or II severity, and the patient is now receiving care for the complication of nonunion, meaning the bone fragments have failed to unite after a typical healing period.

Use this code for patients presenting for follow-up treatment of an open ulnar shaft fracture (Type I or II) that has not healed. This applies when the documentation confirms nonunion but does not specify the exact part of the ulnar shaft involved (e.g., proximal, middle, distal). This code is appropriate for subsequent encounters after the initial treatment of the fracture.

• Ensure documentation clearly states "nonunion" and specifies the initial fracture as an "open fracture type I or II."
• Only use this code when the specific location of the fracture on the ulnar shaft is not documented. If a more precise location is known, a more specific code should be used.
• This code is for subsequent encounters; do not use for the initial treatment of the fracture.
