Other physeal fracture of lower end of ulna, unspecified arm, subsequent encounter for fracture with nonunion

📋Clinical Description

This code describes a fracture involving the growth plate (physis) at the lower end of the ulna, where the specific type of physeal fracture is not further detailed. It indicates that the fracture is not healing as expected (nonunion) and the patient is presenting for follow-up care related to this ongoing issue.

🎯When to Use

Use this code for a patient presenting for a subsequent visit for an unhealed (nonunion) physeal fracture of the distal ulna, when the exact Salter-Harris classification or other specific physeal fracture type is not documented. This applies when the affected arm is not specified in the medical record.

💡Coding Tips

Ensure documentation clearly states "nonunion" for the fracture.
Verify that the encounter is for follow-up care of the fracture, not initial treatment.
Only use this code when the specific type of physeal fracture and the affected arm are not documented.
