Nondisp seg fx shaft of r tibia, 7thN

This code describes a situation where a patient has a non-displaced fracture affecting multiple segments of the shaft of their right tibia. This particular encounter is for the ongoing management of a severe open fracture (Type IIIA, IIIB, or IIIC) that has failed to heal properly, resulting in a nonunion.

Use this code for follow-up encounters when a patient with a previously diagnosed non-displaced, segmental right tibial shaft fracture, which was initially an open fracture of Type IIIA, IIIB, or IIIC, is now presenting with evidence of nonunion. This applies when the fracture site is not healing as expected and further intervention or monitoring for nonunion is required.

• Ensure documentation clearly specifies "nonunion" and the open fracture type (IIIA, IIIB, or IIIC) for the initial injury.
• Verify the fracture is indeed segmental and located in the shaft of the right tibia.
• This code is for subsequent encounters; an initial encounter code would be used for the acute injury.
