About M84.52
M84.52 is the ICD-10-CM diagnosis code for pathological fracture in neoplastic disease, humerus. 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 3 subcodes must be used instead.
Within M84.5 (pathological fracture in neoplastic disease), M84.52 is specifically for pathological fracture in neoplastic disease, humerus. Related codes cover unspecified site (M84.50), shoulder (M84.51), ulna and radius (M84.53), hand (M84.54), pelvis and femur (M84.55), tibia and fibula (M84.56), ankle and foot (M84.57) and other specified site (M84.58).
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.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
