Fracture of coronoid process of left mandible, sequela

This code signifies a long-term complication or late effect resulting from a previous fracture of the coronoid process of the left lower jaw. It indicates that the initial injury has healed, but the patient is now experiencing residual problems directly attributable to that past fracture.

Apply this code when documentation clearly states a sequela (e.g., malunion, nonunion, chronic pain, limited range of motion, deformity) of a healed fracture of the left mandibular coronoid process. The patient's current condition must be a direct consequence of the prior injury, not an acute event.

• Requires a seventh character "S" to denote sequela, indicating the current condition is a late effect of the original injury.
• Always sequence the sequela code first, followed by codes for the specific residual condition(s) being treated (e.g., M26.0- for jaw anomalies, M25.50 for arthralgia).
• Ensure documentation explicitly links the current symptoms or condition to the past fracture of the left coronoid process, not an active fracture.
