Unsp fx shaft of l tibia, 7thR

This code signifies a previously sustained, unspecified fracture of the shaft of the left tibia that was initially an open fracture (Type IIIA, IIIB, or IIIC) and has subsequently healed in a misaligned or deformed position. The patient is receiving ongoing treatment for this malunion.

Use this code for follow-up encounters where a patient is being managed for a malunion of a left tibial shaft fracture that was originally an open fracture of a severe type. This applies when the specific type of shaft fracture (e.g., transverse, oblique) is not documented.

• Requires documentation of a previous open fracture (Type IIIA, IIIB, or IIIC) of the left tibial shaft and current malunion.
• Do not use for initial encounters or for nonunion; specific codes exist for those scenarios.
• Always sequence after the primary reason for the encounter if the malunion is not the primary diagnosis.
