Abrasion of oral cavity, sequela

This code signifies a long-term complication or late effect resulting from a previous abrasion to the oral cavity. This could manifest as scarring, chronic pain, or functional impairment directly attributable to the initial injury. It indicates that the original acute injury has resolved, but its lasting impact continues to affect the patient.

Apply this code when documenting a patient presenting with a current condition that is a direct consequence of an abrasion to the oral cavity that occurred in the past. Documentation should clearly link the current sequela to a previously sustained oral abrasion, often noted in the patient's history or previous encounter notes. This code is appropriate when the acute phase of the abrasion has passed, and the patient is being treated for its residual effects.

• Always sequence the sequela code first, followed by a code describing the specific nature of the sequela (e.g., scar, chronic pain).
• Ensure documentation explicitly states the "sequela of" an oral cavity abrasion, not just a current abrasion.
• Do not use this code for an acute, current abrasion; use the appropriate acute abrasion code from the S00.51- series.
