Contusion of oral cavity, sequela

This code signifies a contusion (bruise) within the oral cavity, such as the tongue, gums, or inner cheeks, where the acute injury has resolved, and the patient is now presenting for treatment or evaluation of a residual effect or complication. This could include persistent pain, scarring, or functional impairment directly attributable to the original blunt trauma.

Apply this code when documentation clearly indicates a past oral cavity contusion and the current encounter addresses a long-term consequence or late effect of that injury. This is appropriate for follow-up visits where the primary reason for the encounter is the sequela, not the initial injury itself.

• Ensure documentation explicitly states the contusion is a past event and the current issue is a sequela.
• Do not use for acute contusions; those require an acute injury code.
• Always sequence this code after the code for the specific sequela (e.g., chronic pain, scar).
