Fx coronoid process of mandible, unspecified side, 7thK

This code signifies a fracture of the coronoid process of the mandible, where the specific side of the fracture is not documented. The "K" seventh character indicates that this is a subsequent encounter for a fracture that has failed to heal properly, resulting in a nonunion.

This code is appropriate for follow-up encounters when a patient is receiving ongoing treatment for a previously diagnosed coronoid process fracture that has not united. Documentation should clearly state "nonunion" or describe the fracture as failing to heal, along with the specific anatomical site.

• Ensure documentation explicitly states "nonunion" for the seventh character "K" to be appropriate.
• Verify the encounter is for ongoing care of the nonunion, not initial treatment or routine follow-up of a healing fracture.
• Always check for laterality (left, right) in the documentation; if specified, a more precise code should be used.
