Displaced subtrochnt fx r femur, subs for clos fx w nonunion

This code describes a fracture located below the lesser trochanter of the right femur, where the bone fragments are no longer in their normal alignment. The fracture has failed to heal properly after an initial treatment, and the patient is presenting for follow-up care related to this nonunion.

This code is appropriate for encounters where a patient is receiving ongoing treatment for a previously diagnosed and treated displaced subtrochanteric fracture of the right femur that has not healed. This includes situations where the patient is undergoing evaluation for nonunion, receiving conservative management for nonunion, or preparing for surgical intervention to address the nonunion.

• Ensure documentation clearly states "nonunion" for the fracture.
• Verify the encounter is for subsequent care, not the initial treatment of the fracture.
• Confirm the fracture location is specifically subtrochanteric and on the right femur.
