Nondisp subtrochnt fx unsp femr, subs for clos fx w malunion

This code describes a situation where a patient has a subtrochanteric fracture of the femur that was not displaced at the time of injury, and the specific femur (left or right) is not documented. The fracture has subsequently healed in an imperfect alignment (malunion) and is currently being managed without surgical intervention for the malunion itself, but rather for ongoing care of the closed fracture.

Use this code when a patient presents for follow-up care of a previously diagnosed, nondisplaced subtrochanteric femur fracture where the laterality is unspecified, and imaging or clinical assessment confirms malunion. This applies to encounters for cast changes, physical therapy, medication management, or other non-surgical treatments related to the healing fracture with malunion.

• Ensure documentation clearly states "malunion" and that the fracture was initially nondisplaced.
• Confirm the encounter is for subsequent care of the closed fracture, not for the initial injury or an open fracture.
• If the laterality (left or right femur) is specified in the documentation, a more specific code should be selected.
