Unsp fx shaft of r tibia, 7thR

This code describes a situation where a patient has previously sustained an open fracture of the shaft of their right tibia, which was classified as a severe (Type IIIA, IIIB, or IIIC) open fracture. The current encounter is for follow-up care or treatment related to this fracture, and it is complicated by malunion, meaning the bone has healed in an incorrect or deformed position. The specific type of fracture of the shaft is not detailed in the documentation.

Use this code for subsequent encounters when a patient presents with a malunion of a previously treated open fracture of the right tibial shaft, specifically when the original open fracture was documented as Type IIIA, IIIB, or IIIC. This applies to ongoing management, assessment, or treatment of the malunion, such as planning for corrective osteotomy or monitoring healing.

• Ensure documentation explicitly states "malunion" and specifies the right tibia shaft.
• Verify the original open fracture was classified as Type IIIA, IIIB, or IIIC.
• This code is for subsequent encounters; an initial encounter would use a different seventh character.
