Burn and corrosion confined to eye and adnexa (T26)

The T26 section of ICD-10-CM codes is specifically used to classify burns and corrosions that are limited to the eye and its surrounding structures, known as the adnexa. These codes cover various types, locations, and degrees of eye burns, including the eyelids, cornea, conjunctival sac, and the eyeball itself.

This detailed category includes codes for burns of the eyelid and periocular area (e.g., T26.00XA), often referred to as epidermal burn of the periorbital region or thermal burn of eyelid. It also covers burns of the cornea and conjunctival sac (e.g., T26.10XA), capturing conditions like corneal burn or thermal injury to conjunctiva. More severe burns resulting in rupture and destruction of the eyeball are coded under T26.2 and related subcodes. Additionally, corrosions caused by chemical burns to the eyelid or cornea are included, with synonyms such as chemical burn of eyelid or alkaline chemical burn of cornea found under codes like T26.50XA and T26.60XA. This ICD-10 code set helps medical coders accurately document the specific eye area affected, laterality (right or left eye), and encounter type (initial, subsequent, or sequela) in cases of ocular burns and corrosions.

Instructional Notations

7th Character Note

Certain ICD-10-CM categories have applicable 7th characters. The applicable 7th character is required for all codes within the category, or as the notes in the Tabular List instruct. The 7th character must always be the 7th character in the data field. If a code that requires a 7th character is not 6 characters, a placeholder X must be used to fill in the empty characters.

  • The appropriate 7th character is to be added to each code from category T26

7th Character

Indicates that a seventh character is to be assigned to codes in a subcategory.

  • A - initial encounter
  • D - subsequent encounter
  • S - sequela
