ICD-10 Code J04.1 – Acute tracheitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J04.1 – Acute tracheitis
What it is
J04.1 identifies acute inflammation of the trachea, the airway that carries air from the larynx to the bronchi. Use it for a sudden-onset tracheal infection or irritation documented as acute tracheitis.
Clinical signs
Typical findings include cough, throat or central chest discomfort, and hoarseness or painful breathing when the trachea is involved. Clinical features vary; refer to documentation.
When to use this code
Use J04.1 when the provider documents acute tracheitis as the primary diagnosis or a confirmed active condition. It may also fit when the note clearly distinguishes tracheal inflammation from laryngitis, bronchitis, or tracheobronchitis. Check documentation if the site of infection is unclear.
Do not use for
Do not use this code for chronic tracheitis, nonspecific upper respiratory infection, or symptoms alone without a documented diagnosis. If the record describes broader airway involvement, verify whether another code is more accurate.
Coding tip
Code the trachea specifically only when the provider names it; otherwise, query for clarification before assigning J04.1.
