Abrasion of oral cavity, initial encounter

This code signifies a superficial injury to the mucous membranes lining the oral cavity, such as the gums, inner cheeks, or palate, where the outer layer of skin has been scraped or rubbed off. It indicates that this is the first time the patient is receiving active treatment for this specific injury.

Apply this code when documentation clearly states an abrasion of any part of the mouth, including the lips (inner surface), tongue, or buccal mucosa, and the patient is in the acute phase of treatment. This is appropriate for initial evaluations, diagnostic workups, and early treatment of the abrasion.

• Ensure documentation specifies "abrasion" and not a laceration or contusion, as these require different codes.
• Confirm the encounter is for the initial treatment of the injury; subsequent care would use a different seventh character.
• Distinguish from abrasions of the external lip (S00.41XA) or other facial regions.
