Abrasion of oral cavity, subsequent encounter

This code signifies a superficial injury to the lining of the mouth, characterized by a scrape or rub that removes the top layer of tissue. It indicates that the patient is receiving follow-up care for an abrasion of the oral cavity after the initial treatment.

Apply this code when a patient presents for ongoing management, healing assessment, or complications related to an oral cavity abrasion that was previously treated. Documentation should clearly state "subsequent encounter" or indicate follow-up care for a previously diagnosed abrasion.

• Ensure documentation specifies "subsequent encounter" to differentiate from initial or sequela encounters.
• Verify the injury is an abrasion and not a laceration or puncture wound, which have different codes.
• Always sequence this code after any primary diagnosis for the reason for the subsequent encounter, if applicable.
