Nondisp subtrochnt fx unsp femr, 7thM

This code signifies a non-displaced fracture located below the lesser trochanter of an unspecified femur, which has progressed to nonunion. This specific nonunion is associated with an initial open fracture classified as Gustilo type I or II, and the patient is currently in a subsequent phase of care.

Apply this code when documentation confirms a subtrochanteric femur fracture that has not healed (nonunion) and was initially an open fracture (Type I or II). This is appropriate for follow-up encounters where the patient is receiving ongoing treatment for the nonunion, such as cast changes, physical therapy, or preparation for revision surgery.

• Ensure the documentation clearly specifies "nondisplaced" and "subtrochanteric" for the fracture site.
• Verify that the initial injury was an "open fracture type I or II" and that "nonunion" is explicitly stated.
• Confirm the encounter is for subsequent care related to the nonunion, not the initial treatment of the acute fracture.
