Unsp physl fx upr end unsp fibula, subs for fx w delay heal

This code signifies a growth plate fracture at the top of the fibula bone in the lower leg, where the specific location or type of fracture is not documented. The patient is in a subsequent phase of care, and the fracture is not healing as expected, indicating delayed union.

Use this code for follow-up encounters when a patient with an unspecific physeal fracture of the proximal fibula is experiencing delayed healing. This applies when the initial fracture details (e.g., laterality, specific physeal plate involved) are not precisely documented, and the physician notes indicate a slower-than-anticipated healing process.

• Ensure documentation clearly states "delayed healing" for this subsequent encounter.
• Confirm that the fracture is of the "upper end" (proximal) of the fibula and involves the growth plate (physeal).
• Avoid using this code if the laterality (left or right) of the fibula is specified in the medical record.
