T26.8Corrosions of other specified parts of eye and adnexa

T26.8 is the ICD-10-CM diagnosis code for Corrosions of other specified parts of eye and adnexa. It belongs to category T26 (burn and corrosion confined to eye and adnexa), block T26-T28 (burns and corrosions confined to eye and internal organs) 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 T26, choose T26.8 (Corrosions of other specified parts of eye and adnexa) only when documentation doesn't support a more specific option: burn of eyelid and periocular area (T26.0), burn of cornea and conjunctival sac (T26.1), burn with resulting rupture and destruction of eyeball (T26.2), burns of other specified parts of eye and adnexa (T26.3), burn of eye and adnexa, part unspecified (T26.4), corrosion of eyelid and periocular area (T26.5), corrosion of cornea and conjunctival sac (T26.6), corrosion with resulting rupture and destruction of eyeball (T26.7) and 1 more.

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.

Code first: (T51-T65) to identify chemical and intent.

Use an additional code for: external cause code to identify place (Y92).

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