About S45.019
S45.019 is the ICD-10-CM diagnosis code for laceration of axillary artery, unspecified side. It belongs to category S45 (injury of blood vessels at shoulder and upper arm level), 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 S45.01, choose S45.019 (unspecified side) only when documentation doesn't support a more specific option: right side (S45.011) and left side (S45.012).
Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. 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.
