Fracture of alveolus of left mandible, init

This code signifies a break in the tooth-bearing part of the lower jawbone on the patient's left side. It specifically indicates that this is the first time the fracture is being treated and that the skin and mucous membranes overlying the fracture site remain intact.

Apply this code for a newly diagnosed, non-compound fracture affecting the alveolar process of the left mandible. Documentation should clearly state "left mandible," "alveolar fracture," "closed fracture," and indicate initial treatment for the injury.

• Ensure the documentation specifies "left" mandible; otherwise, an unspecified laterality code may be more appropriate.
• Verify the fracture is indeed "closed" and not "open" (compound), which would require a different seventh character.
• This "A" seventh character is only for the initial encounter for active treatment of the fracture. Subsequent care would use different seventh characters.
