Fracture of ramus of left mandible, init

This code signifies a broken bone in the ascending portion of the left lower jaw, specifically the ramus. This injury involves a fracture that has not broken through the skin or mucous membranes, and it is the first time the patient is receiving treatment for this specific injury.

Apply this code for a patient presenting with a newly diagnosed, closed fracture of the left mandibular ramus. Documentation should clearly state the location of the fracture (ramus), the side (left), and confirm that it is a closed injury and the initial treatment encounter.

• Ensure laterality (left) is explicitly documented.
• Verify "initial encounter" for the A seventh character; subsequent care would use D, G, K, P, or S.
• Distinguish from other mandibular fracture sites (e.g., body, angle, condylar process) to avoid miscoding.
