M84.86Other disorders of continuity of bone, tibia and fibula

M84.86 is the ICD-10-CM diagnosis code for other disorders of continuity of bone, tibia and fibula. It belongs to category M84 (disorder of continuity of bone), block M80-M85 (disorders of bone density and structure) and chapter 13 (diseases of the musculoskeletal system and connective tissue). It is a header code, so it can't be reported by itself; one of its 5 subcodes must be used instead.

Within M84.8 (other disorders of continuity of bone), M84.86 is specifically for other disorders of continuity of bone, tibia and fibula. Related codes cover unspecified site (M84.80), shoulder (M84.81), humerus (M84.82), ulna and radius (M84.83), hand (M84.84), pelvic region and thigh (M84.85), ankle and foot (M84.87) and other site (M84.88).

To report this condition, pick the subcode that matches the documentation: M84.861 (tibia), M84.862 (tibia), M84.863 (fibula), M84.864 (fibula) and M84.869 (fibula).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
