    ICD-10-CM Code For Burn And Corrosion Of Head Face And Neck: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group T20 includes burns and corrosions of the head, face, and neck, covering thermal, chemical, and electrical injuries to these external anatomical sites and specifying depth and extent where applicable. These ICD-10-CM diagnosis codes are used to document acute traumatic skin injuries to the head and neck, capturing severity, anatomic location, and complications such as infection or tissue necrosis. Accurate coding within the ICD-10-CM T20 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    When to Use

    Use a code from this group when a patient presents with a documented burn or corrosion that is anatomically limited to the head, face, or neck and the clinical record specifies depth or extent. Select the code that reflects the most specific site and severity documented, including any associated complications such as infection or delayed healing.

    Typical Clinical Scenarios

    • An adult presents to the emergency department after a house fire with acute thermal burns to the face and neck, including blistering and partial-thickness skin loss around the right cheek and anterior neck. The patient requires immediate evaluation for airway compromise, pain control, and burn wound management; a burn diagnosis from this group is assigned to capture the site-specific thermal injury and its initial encounter for treatment. Typical codes: T20.111A, T20.112A
    • An elderly nursing home resident is seen in clinic for follow-up of healed but hypertrophic scarring and persistent skin breakdown on the left cheek and chin from a prior corrosive chemical exposure weeks earlier; the visit documents sequelae and ongoing wound care needs. A code from this group is used to indicate the prior burn/corrosion of the head and face as the cause of the current chronic skin changes and management. Typical codes: T20.019D, T20.019S
    • A child is brought to urgent care after a scald injury from hot liquid affecting the nose, upper lip, and perioral area with multiple partial-thickness burns, and the record documents subsequent infection of the burn wound requiring systemic antibiotics. A site-specific acute burn code is assigned for the acute encounter, and an appropriate laterality/extension code from this group captures involvement of the head/face region during the treatment of the infected burn. Typical codes: T20.03XA, T20.03XD
