S90.87Other superficial bite of foot

S90.87 is the ICD-10-CM diagnosis code for other superficial bite of foot. It belongs to category S90 (superficial injury of ankle, foot and toes), block S90-S99 (injuries to the ankle and foot) 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 S90.8, choose S90.87 (Other superficial bite of foot) only when documentation doesn't support a more specific option: abrasion of foot (S90.81), Blister (nonthermal) of foot (S90.82), external constriction of foot (S90.84), superficial foreign body of foot (S90.85) and insect bite (nonvenomous) of foot (S90.86).

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 S90.87 together with the conditions in its Excludes1 note: open bite of foot (S91.35-).

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