S42.00Fracture of unspecified part of clavicle

S42.00 is the ICD-10-CM diagnosis code for fracture of unspecified part 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 3 subcodes must be used instead.

Within S42.0, choose S42.00 (unspecified part of clavicle) only when documentation doesn't support a more specific option: sternal end of clavicle (S42.01), shaft of clavicle (S42.02) and lateral end of clavicle (S42.03).

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.
