Fracture of ramus of left mandible, 7thK

Fracture of ramus of left mandible, subsequent encounter for fracture with nonunion

📋Clinical Description

This code signifies a fracture of the lower jawbone's posterior vertical portion on the left side, specifically when the fracture has failed to heal properly after an initial treatment. It indicates that the patient is receiving ongoing care for this unhealed mandibular ramus fracture.

🎯When to Use

Apply this code for patients presenting for follow-up care, such as clinic visits, imaging studies, or further surgical interventions, for a previously treated left mandibular ramus fracture that has not achieved bony union. Documentation should clearly state "nonunion" and specify the left ramus.

💡Coding Tips

Requires a seventh character "K" for subsequent encounter with nonunion; ensure the correct seventh character is selected based on the encounter type and healing status.
Distinguish from malunion (S02.642P) or routine follow-up for a healing fracture (S02.642D).
Always sequence after any associated external cause codes (e.g., V-codes) if applicable.
