Unspecified fracture of lower end of unspecified ulna, subsequent encounter for closed fracture with nonunion

📋Clinical Description

This code signifies a fracture of the lower end of the ulna where the specific type of fracture is not documented. It is used when the patient is receiving follow-up care for a closed fracture that has failed to heal properly (nonunion).

🎯When to Use

Apply this code for subsequent encounters when a patient presents with a previously diagnosed, closed, unspecified fracture of the distal ulna that has not united. This would include situations where the patient is undergoing continued treatment, evaluation, or management for the nonunion.

💡Coding Tips

Ensure documentation clearly states "nonunion" for a closed fracture of the lower ulna.
Verify that the encounter is for follow-up care, not initial treatment.
Confirm the fracture site is the lower end of the ulna and the laterality is unspecified.
