Greenstick fracture of shaft of humerus, right arm, sequela

This code signifies a greenstick fracture affecting the shaft of the right humerus, where the patient is now experiencing a complication or late effect directly attributable to the original injury. A greenstick fracture is an incomplete fracture where one side of the bone is broken and the other is bent, typically seen in children. The "sequela" indicates that the acute phase of the fracture has passed, and the current encounter addresses a residual problem.

Use this code when documenting a patient encounter for a long-term complication, such as malunion, nonunion, chronic pain, nerve damage, or restricted range of motion, that is a direct result of a previously sustained greenstick fracture of the right humeral shaft. This code is appropriate when the initial fracture has healed or is in the healing phase, but a persistent issue requires ongoing medical attention.

• Always assign a sequela code when the patient is being treated for a complication or late effect of a past injury, not the acute injury itself.
• Ensure documentation clearly links the current condition to the previous greenstick fracture of the right humeral shaft.
• Consider additional codes for the specific nature of the sequela (e.g., M84.0x for malunion, G54.0 for brachial plexus disorders).
