About M84.641
M84.641 is the ICD-10-CM diagnosis code for pathological fracture in other disease, right hand. 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 M84.64 (pathological fracture in other disease, hand), M84.641 is specifically for pathological fracture in other disease, right hand. Related codes cover left hand (M84.642) and unspecified hand (M84.649).
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.
