Unsp physeal fx lower end of ulna, unsp arm, sequela

This code indicates a fracture of the growth plate (physis) at the lower end of the ulna, where the specific type of physeal fracture is not documented. It applies to an injury that occurred on an unspecified arm and is now being treated for its long-term effects or complications (sequela).

Use this code when documentation clearly states a sequela of an unspecified physeal fracture of the distal ulna, and the laterality of the arm is not specified. This is appropriate for follow-up encounters addressing chronic pain, deformity, or functional limitations resulting from the original injury.

• Only use this code for the residual effects of an old injury, not for the initial acute fracture.
• Avoid this code if the specific Salter-Harris classification or laterality (left/right) is documented; more specific codes exist.
• Always review the patient's history and previous encounter notes to confirm the nature of the original injury and its sequelae.
