Diagnostic Code 6504 · 38 CFR §4.97
Laryngeal stenosis is a narrowing of the airway at the level of the larynx (voice box). This can result from intubation injuries, neck trauma, chemical or burn injuries, infections, or surgical complications. Veterans may develop this condition from intubation during field surgery, blast injuries to the neck, inhalation injuries, or tracheostomy complications. The narrowing can range from mild hoarseness to severe breathing restriction requiring a permanent tracheostomy.
