Unsp fx low end unsp tibia, 7thM

This code signifies a fracture of the lower end of the tibia (shin bone) where the specific type of fracture is not documented. It indicates that the patient is receiving follow-up care for an open fracture (where the bone broke through the skin) classified as Type I or II, and the bone fragments have failed to heal together properly (nonunion).

This code is appropriate for subsequent encounters when a patient with a previously diagnosed open Type I or II fracture of the distal tibia is being treated for nonunion, and the specific fracture pattern (e.g., transverse, oblique) is not specified in the medical record. This would include scenarios like follow-up appointments for ongoing management, surgical intervention for nonunion, or evaluation of healing progress.

• Ensure documentation clearly states "nonunion" and specifies the initial fracture as an open Type I or II.
• Verify that the encounter is for subsequent care, not the initial treatment of the fracture.
• If the specific fracture type of the lower tibia is documented, a more specific code should be used instead.
