Nondisp oblique fx shaft of l tibia, 7thM

This code describes a situation where a patient has a non-displaced oblique fracture in the shaft of their left tibia, which was initially an open fracture of type I or II, and is now experiencing nonunion. Nonunion indicates that the bone fragments are not healing together as expected after a previous treatment.

Use this code for follow-up encounters when a patient with a previously diagnosed open type I or II oblique fracture of the left tibial shaft is being treated for nonunion. This applies to ongoing management, assessment, or intervention related to the failed healing of the fracture.

• Ensure documentation clearly specifies "nonunion" and that the original fracture was an "open fracture type I or II."
• Verify the fracture is specifically of the "shaft" and "left tibia" and is "nondisplaced."
• This is a "subsequent encounter" code, so it should not be used for the initial treatment of the fracture.
