About S15.01

S15.01 is the ICD-10-CM diagnosis code for minor laceration of carotid artery. 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 3 subcodes must be used instead.

Within S15.0 (injury of carotid artery of neck), S15.01 is specifically for minor laceration of carotid artery. Related codes cover unspecified injury of carotid artery (S15.00), major laceration of carotid artery (S15.02) and other specified injury of carotid artery (S15.09).

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.
