    ICD-10-CM Code For Burn And Corrosion Of Respiratory Tract: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group T27 includes burns and corrosions of the respiratory tract, covering injuries to the larynx, trachea, bronchi, and lungs caused by heat, smoke, or chemical agents. These ICD-10-CM diagnosis codes are used to document inhalation injuries, airway burns, and corrosive damage to internal respiratory structures, capturing severity and organ involvement. Accurate coding within the ICD-10-CM T27 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    ICD-10-CM T27: Burn And Corrosion Of Respiratory Tract Overview

    This group represents burns and corrosive injuries that specifically affect the respiratory tract, including the larynx, trachea, bronchi, and lungs. These injuries occur from inhalation of heat, smoke, chemical fumes, or corrosive substances and can produce acute airway compromise and long-term respiratory sequelae. Accurate coding is important for documenting the extent of internal organ involvement and supports appropriate reimbursement based on clinical complexity.

    When to Use

    Use a code from this group when a patient has documented thermal or chemical injury to internal respiratory structures confirmed by clinical assessment or diagnostic evaluation. Codes in this group are used to reflect the specific respiratory site(s) affected and the presence of complications related to inhalation or corrosive exposure.

    Typical Clinical Scenarios

    • An adult presents to the emergency department after inhaling hot smoke during a house fire, with acute hoarseness, stridor, cough, and singed nasal hair. Bronchoscopy confirms thermal injury to the larynx and trachea without ongoing care yet; this is an acute burn of the respiratory tract requiring emergent airway assessment and inpatient monitoring. Typical codes: T27.0XXA, T27.3XXA
    • A pediatric patient admitted to the burn unit days after chemical fume exposure at school, now with progressive dyspnea and evidence of mucosal corrosion of the bronchi on endoscopy; the child requires ongoing inpatient treatment and repeat evaluations for healing and airway complications. A code from this group is used to capture the corrosive injury to internal respiratory structures during the current hospital course. Typical codes: T27.2XXA, T27.5XXA
    • An adult with a prior documented inhalation injury from a thermal incident several weeks ago returns for follow-up with persistent airway stenosis and chronic respiratory symptoms; the encounter is for sequelae and complications of the prior burn, requiring outpatient evaluation and planning for definitive airway management. Typical codes: T27.0XXD, T27.3XXD
