S45.0Injury of axillary artery

S45.0 is the ICD-10-CM diagnosis code for injury of axillary artery. 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 (injury of blood vessels at shoulder and upper arm level), S45.0 is specifically for injury of axillary artery. Related codes cover brachial artery (S45.1), axillary or brachial vein (S45.2), superficial vein at shoulder and upper arm level (S45.3), other specified blood vessels at shoulder and upper arm level (S45.8) and unspecified blood vessel at shoulder and upper arm level (S45.9).

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.
