Chronic laryngitis and laryngotracheitis (J37)

The J37 ICD-10 code section covers diagnoses related to chronic inflammation of the larynx and trachea, specifically including chronic laryngitis (J37.0) and chronic laryngotracheitis (J37.1). These codes are used to classify persistent upper respiratory conditions affecting the voice box and windpipe.

Medical coders use ICD-10 code J37.0 for chronic laryngitis, which may also be called chronic epiglottitis, catarrhal laryngitis, or laryngitis sicca. This code applies to long-lasting inflammation causing throat irritation or voice changes. Meanwhile, J37.1 is assigned when both the larynx and trachea are affected, known as chronic laryngotracheitis, sometimes referred to simply as chronic tracheitis. Recognizing these synonyms alongside the official codes helps ensure accurate recording and billing for conditions involving persistent throat inflammation. Thus, the ICD-10 codes in the J37 section specifically identify long-term inflammatory disorders of the larynx and trachea, guiding practitioners in documentation and treatment tracking.
