About S25.12
S25.12 is the ICD-10-CM diagnosis code for major laceration of innominate or subclavian artery. It belongs to category S25 (injury of blood vessels of thorax), block S20-S29 (injuries to the thorax) 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 S25.1 (injury of innominate or subclavian artery), S25.12 is specifically for major laceration of innominate or subclavian artery. Related codes cover unspecified injury of innominate or subclavian artery (S25.10), minor laceration of innominate or subclavian artery (S25.11) and other specified injury of innominate or subclavian artery (S25.19).
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.
