S15.0Injury of carotid artery of neck

S15.0 is the ICD-10-CM diagnosis code for injury of carotid artery of neck. It belongs to category S15 (injury of blood vessels at neck level), block S10-S19 (injuries to the neck) 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 S15 (injury of blood vessels at neck level), S15.0 is specifically for injury of carotid artery of neck. Related codes cover vertebral artery (S15.1), external jugular vein (S15.2), internal jugular vein (S15.3), other specified blood vessels at neck level (S15.8) and unspecified blood vessel at neck level (S15.9).

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.

Don't report S15.0 together with the conditions in its Excludes1 note: injury of internal carotid artery, intracranial portion (S06.8).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
