Unsp physl fx low end ulna, r arm, subs for fx w delay heal

This code signifies a fracture affecting the growth plate (physis) at the lower end of the right ulna, where the specific type of physeal fracture is not documented. It indicates that the patient is in a subsequent phase of care, and the fracture is experiencing delayed healing.

Apply this code when a patient presents for follow-up treatment of an unclassified right distal ulnar physeal fracture that is not progressing to union as expected. This would typically be used after the initial treatment phase, such as during cast changes, physical therapy, or repeat imaging to assess healing progress.

• Ensure documentation explicitly states "delayed healing" for this specific fracture.
• Verify the encounter is subsequent, not initial or for sequela.
• Confirm the fracture location is the lower end of the right ulna and the type of physeal fracture is unspecified.
