Oth physeal fracture of lower end of ulna, unsp arm, init

This code signifies a fracture affecting the growth plate (physis) at the distal end of the ulna, which is the smaller bone in the forearm. The specific type of physeal fracture is not further detailed, and the affected arm is unknown. This diagnosis is for the initial treatment of a closed fracture, meaning the skin remains intact.

This code is appropriate for documenting the initial encounter for a patient presenting with a physeal fracture of the distal ulna when the exact type of physeal injury (e.g., Salter-Harris type) is not specified in the medical record, and the laterality of the arm is not documented. It should be used when the fracture is closed and the patient is receiving their initial active treatment.

• Ensure the documentation explicitly states a physeal fracture of the distal ulna.
• Only use this code if the laterality (left or right arm) is truly unspecified in the medical record.
• Verify that the encounter is for initial treatment and the fracture is closed.
