Nondisp fx of less trochanter of unsp femr, 7thM

This code describes a fracture of the lesser trochanter of the femur that is not displaced, meaning the bone fragments are still in their normal anatomical alignment. This specific code is used when the original injury was an open fracture (Type I or II) and the current encounter addresses a nonunion, indicating the fracture has failed to heal properly. The location of the femur is unspecified.

Use this code for follow-up encounters where a patient is being treated for a nonunion of a previously sustained nondisplaced lesser trochanter fracture. The original fracture must have been an open fracture of either Type I or II. This code would be appropriate for ongoing management, evaluation of healing, or planning for further intervention related to the nonunion.

• Ensure the documentation clearly states "nondisplaced" and "nonunion" for the lesser trochanter fracture.
• Verify the original fracture was an "open fracture type I or II" to justify the 7th character 'M'.
• Always sequence this code after the primary reason for the encounter if the nonunion is a secondary issue.
