Oth physl fx low end ulna, unsp arm, 7thG

This code signifies a fracture affecting the growth plate (physis) at the lower end of the ulna, where the specific type of physeal fracture is not further specified. The injury is located in an unspecified arm, and the patient is currently in a subsequent phase of care because the fracture is not healing at the expected rate.

This code is appropriate for follow-up encounters when a patient presents with an ulnar physeal fracture that has been previously diagnosed, and the physician documents delayed union or non-union. It should be used when the exact Salter-Harris classification or other specific physeal fracture type is not documented, and the affected arm is not specified.

• Ensure documentation explicitly states "delayed healing" or "delayed union" for this subsequent encounter.
• Verify that the fracture is located at the "lower end of ulna" and involves the "physis."
• If the specific type of physeal fracture (e.g., Salter-Harris type) or the affected arm (left/right) is documented, a more specific code should be chosen.
