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

This code signifies a fracture of an unspecified femur that occurred due to an underlying disease process, not from trauma. The patient is in a subsequent phase of care, and the fracture is experiencing delayed healing. This indicates ongoing management for a non-union or slow-to-heal pathological femoral fracture.

Apply this code when a patient presents for follow-up care of a pathological fracture of the femur, where the specific location (e.g., shaft, neck) is not documented, and healing is progressing slower than expected. Documentation should clearly state "pathological fracture," "unspecified femur," and "delayed healing" during a subsequent encounter.

• Ensure documentation specifies "pathological fracture" and not a traumatic fracture.
• This code requires a seventh character "G" for subsequent encounter with delayed healing; do not use "A" for initial or "P" for malunion.
• If the specific site of the femoral fracture is known (e.g., neck, shaft), a more specific code from the M84.65- subcategory should be used.
