S00.26Insect bite (nonvenomous) of eyelid and periocular area

S00.26 is the ICD-10-CM diagnosis code for insect bite (nonvenomous) of eyelid and periocular area. It belongs to category S00 (superficial injury of head), block S00-S09 (injuries to the head) 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 S00.2 (other and unspecified superficial injuries of eyelid and periocular area), S00.26 is specifically for insect bite (nonvenomous) of eyelid and periocular area. Related codes cover unspecified superficial injury of eyelid and periocular area (S00.20), abrasion of eyelid and periocular area (S00.21), Blister (nonthermal) of eyelid and periocular area (S00.22), external constriction of eyelid and periocular area (S00.24), superficial foreign body of eyelid and periocular area (S00.25) and other superficial bite of eyelid and periocular area (S00.27).

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.
