S42.222-part fracture of surgical neck of humerus

S42.22 is the ICD-10-CM diagnosis code for 2-part fracture of surgical neck of humerus. It belongs to category S42 (fracture of shoulder and upper arm), block S40-S49 (injuries to the shoulder and upper arm) and chapter 19 (injury, poisoning and certain other consequences of external causes). It is a header code, so it can't be reported by itself; one of its 6 subcodes must be used instead.

Within S42.2 (fracture of upper end of humerus), S42.22 is specifically for 2-part fracture of surgical neck of humerus. Related codes cover unspecified fracture of upper end of humerus (S42.20), unspecified fracture of surgical neck of humerus (S42.21), 3-part fracture of surgical neck of humerus (S42.23), 4-part fracture of surgical neck of humerus (S42.24), fracture of greater tuberosity of humerus (S42.25), fracture of lesser tuberosity of humerus (S42.26), Torus fracture of upper end of humerus (S42.27) and other fracture of upper end of humerus (S42.29).

Codes in this range require a 7th character: A for initial encounter for closed fracture, B for initial encounter for open 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 1 more. 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.
