About S65.41
S65.41 is the ICD-10-CM diagnosis code for laceration of blood vessel of thumb. It belongs to category S65 (injury of blood vessels at wrist and hand level), block S60-S69 (injuries to the wrist, hand and fingers) 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 S65.4 (injury of blood vessel of thumb), S65.41 is specifically for laceration of blood vessel of thumb. Related codes cover unspecified injury of blood vessel of thumb (S65.40) and other specified injury of blood vessel of thumb (S65.49).
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.
