M84.8Other disorders of continuity of bone

M84.8 is the ICD-10-CM diagnosis code for other disorders of continuity of bone. 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 9 subcodes must be used instead.

Within M84, choose M84.8 (Other disorders of continuity of bone) only when documentation doesn't support a more specific option: stress fracture (M84.3), pathological fracture, not elsewhere classified (M84.4), pathological fracture in neoplastic disease (M84.5), pathological fracture in other disease (M84.6), nontraumatic fracture, not elsewhere classified (M84.7) and unspecified (M84.9).

To report this condition, pick the subcode that matches the documentation: M84.80 (unspecified site), M84.81 (shoulder), M84.82 (humerus), M84.83 (ulna and radius), M84.84 (hand), M84.85 (pelvic region and thigh), M84.86 (tibia and fibula), M84.87 (ankle and foot) and 1 more.

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