Greenstick fx shaft of right ulna, subs for fx w nonunion

This code signifies a specific type of incomplete fracture, a greenstick fracture, affecting the shaft of the right ulna. It indicates that the patient is in a subsequent phase of care for this fracture, and a nonunion (failure of the bone to heal) has been identified.

This code is appropriate for follow-up encounters where a patient is being treated for a greenstick fracture of the right ulnar shaft that has not healed properly. This includes situations where further interventions, such as surgical repair for nonunion or ongoing conservative management, are being provided.

• Ensure documentation clearly specifies "greenstick" and "nonunion" for the right ulnar shaft.
• Verify that the encounter is for subsequent care, not the initial treatment.
• Always code the underlying condition (nonunion) in addition to the fracture type and location.
