Greenstick fracture of shaft of humerus, left arm, sequela

This code signifies a greenstick fracture affecting the shaft of the left humerus, specifically indicating a sequela. A greenstick fracture is an incomplete fracture where the bone bends and cracks but does not break all the way through, typically seen in children. The "sequela" designation means this code is used for complications or conditions arising as a direct result of the initial fracture, even after the acute phase of healing has passed.

This code is appropriate when documenting a long-term complication or residual effect stemming from a previously sustained greenstick fracture of the left humeral shaft. Examples include malunion, nonunion, chronic pain, nerve damage, or limited range of motion directly attributable to the original injury. It should be used when the patient is presenting for treatment of these persistent issues, not for the initial acute injury.

• Always assign an additional code to specify the nature of the sequela (e.g., M84.222A for delayed union of fracture of shaft of left humerus).
• Ensure documentation clearly links the current condition to the prior greenstick fracture of the left humeral shaft.
• Do not use this code for the initial acute greenstick fracture; separate codes exist for active treatment.
