Fracture of ramus of mandible, unspecified side, init

This code signifies a break in the ascending or horizontal portion of the lower jawbone, specifically the ramus, where the side is not specified. It indicates the initial treatment phase for a fracture that has not broken through the skin or mucous membranes.

Apply this code for a patient presenting with a newly diagnosed, closed fracture of the mandibular ramus, when the medical record does not specify whether the left or right side is affected. Documentation should clearly state "ramus fracture," "closed," and indicate the initial encounter for treatment.

• Ensure documentation specifies "closed fracture" and "initial encounter" to avoid using subsequent or open fracture codes.
• If the side (left or right) of the ramus fracture is documented, use the more specific codes S02.641A or S02.642A.
• Always review for associated injuries, such as dental trauma or other facial fractures, which may require additional coding.
