S42.0Fracture of clavicle

S42.0 is the ICD-10-CM diagnosis code for fracture of clavicle. 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 4 subcodes must be used instead.

Within S42 (fracture of shoulder and upper arm), S42.0 is specifically for fracture of clavicle. Related codes cover scapula (S42.1), upper end of humerus (S42.2), shaft of humerus (S42.3), lower end of humerus (S42.4) and shoulder girdle, part unspecified (S42.9).

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.
