Displ spiral fx shaft of unsp fibula, 7thK

This code describes a fracture involving the shaft of the fibula, where the bone fragments are no longer in their normal alignment (displaced) and the fracture line has a spiral pattern. The "subsequent encounter" indicates ongoing treatment for the fracture, and "nonunion" signifies that the bone has failed to heal completely after a typical healing period. The unspecified fibula indicates laterality is not documented.

Use this code for patients presenting for follow-up care, cast changes, or other ongoing management of a previously diagnosed displaced spiral fibular shaft fracture that has not united. This applies when the documentation explicitly states nonunion and does not specify left or right fibula.

• Ensure documentation clearly states "nonunion" and "subsequent encounter" for a displaced spiral fibular shaft fracture.
• Only use this code when laterality (left or right) of the fibula is not specified in the medical record.
• Pair with external cause codes (e.g., V00-Y99) to describe the circumstances of the injury, if applicable.
