About T26.7

T26.7 is the ICD-10-CM diagnosis code for corrosion with resulting rupture and destruction of eyeball. 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 (burn and corrosion confined to eye and adnexa), T26.7 is specifically for corrosion with resulting rupture and destruction of eyeball. Related codes cover 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), Corrosions of other specified parts of eye and adnexa (T26.8) 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.
