Fx coronoid process of mandible, unspecified side, init

This code signifies a break in the coronoid process, a small, triangular projection of bone located on the anterior aspect of the mandibular ramus. This specific fracture is closed, meaning the skin and underlying soft tissues remain intact, and the side of the mandible affected is not specified in the documentation.

Apply this code for initial encounters when a patient presents with a newly diagnosed, closed fracture of the coronoid process of the mandible, and the medical record does not specify laterality (left or right). Documentation should clearly state "coronoid process fracture," "closed," and indicate it's the first time the patient is being treated for this specific injury.

• Ensure documentation explicitly states "coronoid process" to differentiate from other mandibular fractures.
• Verify the encounter is truly "initial" for this specific injury; subsequent care would use a different seventh character.
• If laterality (left or right) is documented, a more specific code should be selected.
