Nondisp subtrochnt fx l femur, subs for clos fx w malunion

This code signifies a fracture located below the lesser trochanter of the left femur that was not displaced at the time of injury. The patient is in a subsequent phase of care, and the fracture has healed improperly, resulting in a malunion.

Use this code for follow-up encounters where a patient is being treated for a previously diagnosed nondisplaced subtrochanteric fracture of the left femur that has healed in an anatomically incorrect position. This would apply to situations where the malunion is being evaluated or managed, such as for pain, functional limitations, or consideration of corrective surgery.

• Ensure documentation clearly states "left femur" and "subtrochanteric" location.
• Verify the fracture was initially "nondisplaced" and that the current encounter addresses a "malunion."
• The "X" placeholder indicates the 7th character for subsequent encounter, which is crucial for proper coding.
