Unsp fx low end unsp ulna, 7thQ

Unspecified fracture of lower end of unspecified ulna, subsequent encounter for open fracture type I or II with malunion

📋Clinical Description

This code signifies an open fracture (Type I or II) of the distal ulna, where the bone has healed in an abnormal or misaligned position (malunion). This specific encounter is for ongoing treatment of this previously sustained injury.

🎯When to Use

Apply this code when a patient presents for follow-up care, rehabilitation, or further surgical intervention related to a malunited open fracture of the lower end of the ulna. This includes scenarios where the malunion is causing functional impairment or pain.

💡Coding Tips

Ensure documentation clearly specifies an open fracture (Type I or II) and evidence of malunion.
This code is for subsequent encounters, not the initial treatment of the fracture.
Verify the laterality (left, right, or unspecified) of the ulna fracture if available in the medical record.
