Pathological fracture, unsp femur, subs for fx w delay heal

This code signifies a fracture of an unspecified femur that occurred due to a pre-existing disease process (e.g., osteoporosis, tumor), not trauma. The "subsequent encounter" indicates the patient is receiving routine care during the healing phase, and "delayed healing" specifies that the fracture is not mending at the expected rate.

Apply this code for follow-up visits where a patient is being managed for a pathological fracture of the femur that is not healing as anticipated. Documentation should clearly state "pathological fracture," specify the femur (even if unspecified), and indicate delayed healing during a subsequent encounter for fracture care.

• Ensure documentation explicitly states "pathological fracture" and "delayed healing" to support this specific code.
• Do not use this code for initial fracture treatment or for nonunion/malunion, which have distinct codes.
• Always sequence this code after the underlying condition causing the pathological fracture (e.g., osteoporosis, neoplasm).
