Fx coronoid process of mandible, unspecified side, 7thB

This code signifies a broken coronoid process, which is a triangular projection on the anterior aspect of the mandibular ramus. The fracture is an open type, meaning there is a break in the skin or mucous membrane communicating with the fracture site, and this is the initial treatment encounter for the injury.

Apply this code for patients presenting with a newly diagnosed open fracture of the coronoid process of the mandible. Documentation should clearly state an open fracture and specify the initial encounter for treatment. This code is appropriate when the side of the mandible affected is not specified in the medical record.

• Ensure documentation explicitly states "open fracture" to differentiate from closed fractures.
• Verify that this is the initial encounter for active treatment of the fracture, not a subsequent encounter for healing or sequela.
• If the side of the mandible (left or right) is documented, a more specific code should be used.
