Nondisp bicondylar fx unsp tibia, 7thN

This code describes a fracture involving both condyles of the tibia that has not shifted from its anatomical position. It specifically indicates that the fracture was initially an open fracture of a severe type (IIIA, IIIB, or IIIC) and is now being treated for a nonunion, meaning the bone has failed to heal properly.

Use this code for follow-up encounters where a patient with a previously diagnosed nondisplaced bicondylar tibial fracture, initially classified as a severe open fracture, is receiving ongoing care for a documented nonunion. This applies when the fracture site shows no signs of healing after the expected time frame.

• Ensure documentation clearly specifies "nondisplaced" and "bicondylar" for the tibia.
• Verify the initial open fracture type was IIIA, IIIB, or IIIC, and that nonunion is explicitly stated.
• This code is for subsequent encounters; an initial encounter would use a different code.
