Fracture of angle of left mandible, 7thK

This code signifies a fracture located at the angle of the left lower jawbone that has failed to heal properly after initial treatment. The "K" seventh character indicates that this is a subsequent encounter for the nonunion, meaning the patient is receiving ongoing care for the unhealed fracture.

Apply this code when a patient presents for follow-up care, surgical intervention, or management of a previously treated left mandibular angle fracture that has not united. Documentation should clearly state "nonunion" of the fracture and specify the left side and angle location.

• Ensure documentation explicitly states "nonunion" and not just delayed healing or malunion.
• Verify the laterality (left) and specific anatomical site (angle of mandible).
• This code requires a seventh character; "K" is for subsequent encounter with nonunion. Other seventh characters exist for initial encounters or subsequent encounters with routine healing/malunion.
