Coronoid process, loss of (DC 9909)

Body system: Dental and Oral ConditionsRegulation: 38 CFR § 4.150

The coronoid process is a small, beak-shaped piece of bone at the front of your lower jaw that helps with chewing muscles. Loss of this bone structure can happen from trauma, surgery, or severe dental infections. The VA rates this condition based on whether it affects one side (unilateral) at 10% or both sides (bilateral) at 20%. Since this affects your ability to chew and open your mouth properly, even the 10% rating recognizes the daily impact on eating and speaking.

Rating levels

  • 20% — You qualify for this rating if you have lost the coronoid process (small bony projections at the front of your lower jaw) on both sides of your mouth. This affects your ability to open your mouth fully and can impact chewing, speaking, and jaw movement since these bone structures help your jaw muscles function properly.
  • 10% — You qualify if you've lost the coronoid process (a small bony projection at the front of your lower jaw) on one side of your mouth only. This bone loss affects how your jaw muscles attach and can impact chewing function on that side.
