About S61.1

S61.1 is the ICD-10-CM diagnosis code for open wound of thumb with damage to nail. It belongs to category S61 (open wound of wrist, hand and fingers), 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 6 subcodes must be used instead.

Within S61 (open wound of wrist, hand and fingers), S61.1 is specifically for open wound of thumb with damage to nail. Related codes cover thumb without damage to nail (S61.0), other finger without damage to nail (S61.2), other finger with damage to nail (S61.3), hand (S61.4) and wrist (S61.5).

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.
