Unsp fx shaft of unsp tibia, 7thM

This code signifies a nonunion of an open fracture (Type I or II) affecting the shaft of an unspecified tibia. Nonunion indicates that the bone has failed to heal completely after a previous fracture, and the "unspecified" nature means the specific location on the tibial shaft is not documented. This code is used for subsequent encounters where the patient is receiving active treatment for this nonunion.

Use this code for follow-up visits or hospitalizations where a patient is being treated for a previously diagnosed open tibial shaft fracture (Gustilo-Anderson Type I or II) that has not healed and is now considered a nonunion. This includes scenarios involving surgical intervention for nonunion, cast changes, or ongoing medical management.

• Ensure documentation clearly states "nonunion" and specifies an open fracture type I or II.
• Verify that the encounter is for active treatment of the nonunion, not just routine follow-up after successful healing.
• Confirm the fracture location is the tibial shaft, even if the specific segment (e.g., proximal, middle, distal) is not specified.
