Displ commnt fx shaft of unsp tibia, 7thN

This code describes a complex fracture of the main part of the shin bone (tibia) that has broken into multiple pieces and is out of alignment. It specifically indicates that the fracture is an open fracture (meaning the bone broke through the skin) of a severe type (IIIA, IIIB, or IIIC) and has failed to heal properly, resulting in a nonunion.

Use this code for a patient presenting for ongoing management of a previously diagnosed displaced comminuted open tibial shaft fracture (Type IIIA, IIIB, or IIIC) that has progressed to a nonunion. This applies to follow-up visits, cast changes, or preparations for further surgical intervention to address the nonunion.

• Ensure documentation clearly specifies "nonunion" and the open fracture type (IIIA, IIIB, or IIIC).
• Verify that the encounter is for subsequent care, not the initial treatment of the fracture.
• Confirm the fracture is of the "shaft" of the tibia, not the proximal or distal ends.
