Loss of jaw coronoid process

The key question under this code is whether the loss of the coronoid process is unilateral or bilateral, so evidence needs to clearly show which side or sides are affected. Diagnostic imaging is the primary way to establish that. VA recognizes conventional X-rays, CT scans, MRI, PET scans, radionuclide bone scans, and ultrasound as acceptable imaging studies for this purpose. Radiology reports that describe the absence of the coronoid process on one or both sides would directly address the rating criteria.

Operative reports, pathology reports, or treatment records from oral surgery that document removal or destruction of the coronoid process can also support the evidence picture. If you have related symptoms such as changes in speech, smell, taste, nerve function, or breathing, separate medical records and findings documenting those conditions would support additional ratings evaluated under their own diagnostic codes.
