About S42.019

S42.019 is the ICD-10-CM diagnosis code for nondisplaced fracture of sternal end of unspecified 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 7 subcodes must be used instead.

Within S42.01, choose S42.019 (Nondisplaced fracture of sternal end of unspecified clavicle) only when documentation doesn't support a more specific option: anterior displaced fracture of sternal end of right clavicle (S42.011), anterior displaced fracture of sternal end of left clavicle (S42.012), anterior displaced fracture of sternal end of unspecified clavicle (S42.013), posterior displaced fracture of sternal end of right clavicle (S42.014), posterior displaced fracture of sternal end of left clavicle (S42.015), posterior displaced fracture of sternal end of unspecified clavicle (S42.016), nondisplaced fracture of sternal end of right clavicle (S42.017) and nondisplaced fracture of sternal end of left clavicle (S42.018).

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.
