M84.751Incomplete atypical femoral fracture, right leg

M84.751 is the ICD-10-CM diagnosis code for incomplete atypical femoral fracture, right leg. 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 6 subcodes must be used instead.

Within M84.75 (atypical femoral fracture), M84.751 is specifically for incomplete atypical femoral fracture, right leg. Related codes cover unspecified (M84.750), incomplete atypical femoral fracture, left leg (M84.752), incomplete atypical femoral fracture, unspecified leg (M84.753), complete transverse atypical femoral fracture, right leg (M84.754), complete transverse atypical femoral fracture, left leg (M84.755), complete transverse atypical femoral fracture, unspecified leg (M84.756), complete oblique atypical femoral fracture, right leg (M84.757), complete oblique atypical femoral fracture, left leg (M84.758) and 1 more.

Codes in this range require a 7th character: A for initial encounter for fracture, D for subsequent encounter for fracture with routine healing, G for subsequent encounter for fracture with delayed healing, K for subsequent encounter for fracture with nonunion, P for subsequent encounter for fracture with malunion and S for sequela.
