M84.756Complete transverse atypical femoral fracture, unspecified leg

M84.756 is the ICD-10-CM diagnosis code for complete transverse atypical femoral fracture, unspecified 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, choose M84.756 (Complete transverse atypical femoral fracture, unspecified leg) only when documentation doesn't support a more specific option: unspecified (M84.750), incomplete atypical femoral fracture, right leg (M84.751), 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 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. Use placeholder "X" characters to fill any empty positions before the 7th character.
