Sltr-haris Type II physl fx low end ulna, unsp arm, 7thP

This code describes a specific type of growth plate fracture (Salter-Harris Type II) affecting the lower part of the ulna bone in an unspecified arm. The fracture is in a stage of healing where the bone fragments have joined together, but in an incorrect or deformed position. This indicates a complication of the healing process.

This code is used when a patient presents for follow-up care of a previously diagnosed Salter-Harris Type II physeal fracture of the distal ulna, and imaging or clinical assessment confirms that the fracture has healed with malunion. This would apply to encounters for ongoing management, evaluation of function, or planning for corrective procedures related to the malunion.

• Ensure documentation clearly states "malunion" and specifies the Salter-Harris Type II classification for the distal ulna.
• Verify that the encounter is for subsequent care of the fracture, not the initial treatment.
• Confirm the laterality is unspecified if not documented, otherwise, a more specific code for left or right arm should be used.
