Fracture of coronoid process of right mandible, sequela

This code describes a long-term complication or late effect resulting from a previous fracture of the coronoid process of the right mandible. It indicates that the patient is experiencing ongoing issues directly attributable to the healed or resolving fracture, rather than the acute injury itself.

Use this code when documenting a patient presenting with residual symptoms or conditions (e.g., malunion, nonunion, chronic pain, restricted jaw movement) that are a direct consequence of a past fracture of the right mandibular coronoid process. Documentation should clearly link the current condition to the prior fracture and indicate that the acute phase of the injury has passed.

• Always sequence this S-code as a secondary diagnosis, following the code for the specific sequela (e.g., M26.89 for other specified dentofacial anomalies).
• Ensure documentation explicitly states "sequela," "late effect," or describes a chronic condition directly resulting from a past fracture.
• Do not use for initial or subsequent encounters for the active treatment of the acute fracture.
