About S42.41

S42.41 is the ICD-10-CM diagnosis code for simple supracondylar fracture without intercondylar fracture 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 S42.4, choose S42.41 (Simple supracondylar fracture without intercondylar fracture of humerus) only when documentation doesn't support a more specific option: unspecified fracture of lower end of humerus (S42.40), comminuted supracondylar fracture without intercondylar fracture of humerus (S42.42), fracture (avulsion) of lateral epicondyle of humerus (S42.43), fracture (avulsion) of medial epicondyle of humerus (S42.44), fracture of lateral condyle of humerus (S42.45), fracture of medial condyle of humerus (S42.46), transcondylar fracture of humerus (S42.47), Torus fracture of lower end of humerus (S42.48) and 1 more.

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.
