S65.9Injury of unspecified blood vessel at wrist and hand level

S65.9 is the ICD-10-CM diagnosis code for injury of unspecified blood vessel at wrist and hand level. 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, choose S65.9 (unspecified blood vessel at wrist and hand level) only when documentation doesn't support a more specific option: ulnar artery at wrist and hand level (S65.0), radial artery at wrist and hand level (S65.1), superficial palmar arch (S65.2), deep palmar arch (S65.3), blood vessel of thumb (S65.4), blood vessel of other and unspecified finger (S65.5) and other blood vessels at wrist and hand level (S65.8).

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.
