Path fx in oth disease, l femur, subs for fx w delay heal

This code signifies a fracture of the left femur that occurred due to an underlying disease process, rather than trauma, and is currently experiencing delayed healing. It indicates that the patient is receiving active treatment for the fracture during this encounter, but the healing process is not progressing at the expected rate.

Use this code for follow-up encounters where a patient with a pathological fracture of the left femur, caused by a separate underlying condition, is being treated for delayed union or nonunion. Documentation should clearly state "pathological fracture," specify the left femur, and indicate "delayed healing" or similar terms during a subsequent encounter.

• Ensure documentation specifies the underlying disease causing the pathological fracture.
• Distinguish from initial encounters (initial encounter for fracture) or encounters for routine healing.
• Verify laterality (left femur) is clearly documented to avoid coding errors.
