Unsp fx shaft of unsp tibia, 7thQ

This code describes a situation where a patient is being treated for a previously diagnosed open fracture (Type I or II) of the shaft of an unspecified tibia, and the fracture is now healing incorrectly (malunion). The specific location of the fracture on the tibial shaft is not documented, nor is the laterality (left or right leg).

This code is appropriate for follow-up encounters when a patient presents with complications from an open tibial shaft fracture that is healing with malunion. It should be used when the initial fracture was classified as an open Type I or II, and the specific site on the shaft or laterality is not detailed in the medical record. This code indicates ongoing care for the healing complication.

• Ensure the documentation clearly states "malunion" and that the encounter is "subsequent" to the initial injury.
• Verify the original fracture was an "open fracture Type I or II"; if it was Type III or a closed fracture, a different code is required.
• Only use this code when the specific location on the tibial shaft and laterality are truly unspecified in the medical record.
