    ICD-10-CM Code For Burn And Corrosion Confined To Eye And Adnexa: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group T26 includes injuries from burns and corrosive agents that are confined to the eye and adnexa, specifying the type and extent of ocular tissue damage. These ICD-10-CM diagnosis codes are used to document clinical scenarios involving thermal, chemical, or radiation injuries to the eye and surrounding structures, capturing severity and specific anatomic involvement. Accurate coding within the ICD-10-CM T26 group supports proper claim adjudication and complete clinical documentation for appropriate reimbursement.

    ICD-10-CM T26: Burn And Corrosion Confined To Eye And Adnexa Overview

    The diagnosis codes in this group represent burns and corrosive injuries that are limited to the eye and its adnexal structures, including the eyelids, lacrimal apparatus, and surrounding tissues. These codes target ocular trauma from thermal, chemical, or radiation sources and indicate the anatomic site and severity of injury. Accurate coding matters for clinical documentation and reimbursement because it communicates the extent of ocular involvement and informs appropriate claim adjudication.

    When to Use

    Use a code from this group when clinical documentation identifies a burn or corrosive injury confined to the eye or its adnexa without involvement of internal organs. Select the specific code that matches the documented cause, laterality, and level of tissue damage to reflect severity and facilitate accurate claims processing.

    Typical Clinical Scenarios

    • A factory worker presents to the emergency department after a chemical splash to the face and eyes while cleaning machinery. On exam there is acute corneal opacity, conjunctival blanching, severe pain, and reduced visual acuity; urgent irrigation and ophthalmology evaluation are performed. Because the injury is an acute burn/corrosion confined to the eye/adnexa due to a corrosive chemical, a code for a chemical burn of the eye with initial encounter is assigned. Typical codes: T26.02XA, T26.12XA
    • An elderly patient in a long-term care facility develops progressive eyelid scarring and persistent corneal epithelial defects weeks after thermal exposure from a small household fire. The patient is seen in clinic for ongoing wound care and visual rehabilitation; the encounter documents sequelae of the prior burn causing chronic changes to the eye and adnexa. A code indicating a sequela (late effect) of burn/corrosion to the eye is used to capture the chronic condition. Typical codes: T26.00XS, T26.10XS
    • A child is brought to urgent care after accidentally pouring a hot beverage into the face, with partial-thickness burns of the eyelids and periocular skin plus conjunctival irritation; treatment includes wound care and tetanus update. Because this is a thermal burn involving the eyelids/adjacent adnexal structures during the initial encounter, an initial encounter code for thermal burn of the eye/adnexa is selected. Typical codes: T26.30XA, T26.31XA
