Nondisp intertroch fx unsp femr, 7thN

This code describes a situation where a patient has a previously diagnosed intertrochanteric fracture of an unspecified femur that was not displaced at the time of injury. The fracture was an open fracture of severe type (IIIA, IIIB, or IIIC), and despite prior treatment, the bone fragments have failed to heal together, resulting in a nonunion.

Use this code for follow-up encounters where a patient is being treated for a nonunion of a previously documented open intertrochanteric fracture. This applies when the original fracture was nondisplaced and classified as an open type IIIA, IIIB, or IIIC. This code would be appropriate for ongoing management, evaluation of nonunion, or planning for revision surgery.

• Ensure documentation clearly specifies "nonunion" and the original fracture was an open type IIIA, IIIB, or IIIC.
• Confirm the fracture was intertrochanteric and nondisplaced, even if the later complication is nonunion.
• This code is for subsequent encounters; an initial encounter code would have been used for the acute injury.
