Greenstick fracture of shaft of humerus, unsp arm, sequela

This code signifies a past greenstick fracture affecting the shaft of the humerus, where the specific arm (left or right) was not documented. A greenstick fracture is an incomplete break, common in children, where one side of the bone is broken and the other is bent. The "sequela" designation indicates that this code is used for conditions or complications arising as a direct result of the original injury, long after the initial healing period.

This code is appropriate when documenting a current condition or complication that is a direct consequence of a previously sustained greenstick fracture of the humeral shaft, and the laterality of the original injury is unknown. Examples include chronic pain, malunion, nonunion, or functional limitations stemming from the old fracture. It should be used when the patient is no longer in the active treatment phase for the initial fracture.

• Always ensure documentation clearly links the current condition to the past greenstick fracture of the humerus.
• Do not use this code for the initial encounter or active treatment of the fracture; instead, use the acute fracture codes.
• If the laterality (left or right arm) of the original injury is known, select the more specific sequela code.
