S90.451Superficial foreign body, right great toe

S90.451 is the ICD-10-CM diagnosis code for superficial foreign body, right great toe. 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 S90.45 (superficial foreign body of toe), S90.451 is specifically for superficial foreign body, right great toe. Related codes cover left great toe (S90.452), unspecified great toe (S90.453), right lesser toe(s) (S90.454), left lesser toe(s) (S90.455) and unspecified lesser toe(s) (S90.456).

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.
