About S61.15

S61.15 is the ICD-10-CM diagnosis code for open bite 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 3 subcodes must be used instead.

Within S61.1 (open wound of thumb with damage to nail), S61.15 is specifically for open bite of thumb with damage to nail. Related codes cover unspecified open wound of thumb with damage to nail (S61.10), laceration without foreign body of thumb with damage to nail (S61.11), laceration with foreign body of thumb with damage to nail (S61.12), puncture wound without foreign body of thumb with damage to nail (S61.13) and puncture wound with foreign body of thumb with damage to nail (S61.14).

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.

Don't report S61.15 together with the conditions in its Excludes1 note: superficial bite of thumb (S60.36-, S60.37-).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
