Oth fx upr & low end unsp fibula, 7thK

This code describes a fracture involving either the upper or lower end of the fibula, where the specific location (e.g., lateral malleolus, fibular head) is not documented. The fracture is currently in a nonunion state, meaning it has failed to heal adequately, and the patient is receiving follow-up care for this closed injury.

This code is appropriate for subsequent encounters when a patient presents with a previously diagnosed, unspecified closed fracture of the fibula's upper or lower end that has not healed. This includes situations where the patient is undergoing treatment for the nonunion, such as bone stimulation, revision surgery planning, or continued conservative management.

• Ensure documentation clearly states "nonunion" for a closed fracture of the fibula's upper or lower end.
• Only use this code for subsequent encounters; an initial encounter would require a different seventh character.
• If the specific location of the fracture (e.g., lateral malleolus) is documented, a more specific code should be used.
