Displ commnt fx shaft of r tibia, 7thR

This code signifies a complex fracture of the right tibia's shaft, specifically a comminuted break where the bone is shattered into multiple pieces and is no longer properly aligned. It further specifies that this is a subsequent encounter for an open fracture of a severe type (IIIA, IIIB, or IIIC), and the bone has healed in an incorrect or deformed position (malunion).

Use this code for follow-up care of a patient who previously sustained a severe open comminuted fracture of the right tibial shaft, and imaging or clinical assessment confirms that the fracture has healed with malunion. This would apply during clinic visits, physical therapy, or surgical planning for corrective procedures related to the malunion.

• Ensure documentation clearly specifies "malunion" and the open fracture type (IIIA, IIIB, or IIIC).
• Verify laterality (right tibia) and the specific bone section (shaft) are documented.
• This code is for subsequent encounters; use an initial encounter code for the acute injury.
