The following subcategories have been expanded to allow the ability to report laterality for these types of fractures of the skull and facial bones:
S02.1 Fracture of base of skull
S02.3 Fracture of orbital floor
S02.4 Fracture of malar, maxillary, and zygoma bones
S02.6 Fracture of mandible
S02.8 Fracture of other specified skull and facial bones
The occipital bone is a trapezoid shaped bone found at the lower back area of the cranium and is comprised of four parts: the basilar part, two condylar parts, and the squamous part. Occipital fractures may be further specified as type I, type II or type III fractures, with codes for left, right or unspecified side.
Fractures of the mandible are further broken down to allow the capturing of fractures of the condylar process, subcondylar process, coronoid process, ramus, angle, symphysis or alveolus of the mandible. Codes will now be available to capture the right, left or unspecified side of these mandibular sites.
