Displ spiral fx shaft of unsp tibia, 7thQ

This code describes a tibia fracture that has not healed correctly (malunion) following an initial injury. The fracture is located in the shaft of the tibia, has a spiral pattern, and the bone fragments are no longer in their normal alignment (displaced). This specific code is used for a subsequent encounter where the initial injury was an open fracture of type I or II, meaning there was a wound communicating with the fracture site.

This code is appropriate for documenting follow-up care for a patient who previously sustained an open spiral fracture of the tibial shaft, type I or II, and is now presenting with evidence of malunion. This could include clinic visits for assessment of healing, imaging studies confirming the malunion, or planning for corrective procedures. It specifically applies when the laterality (left or right) of the tibia is not documented.

• Ensure documentation clearly states "malunion" and specifies the original fracture as an "open fracture type I or II."
• Verify that the encounter is a "subsequent encounter" for the fracture, not the initial treatment.
• Only use this code when the laterality of the tibia is truly unspecified in the medical record. If laterality is known, a more specific code should be chosen.
