Chronic laryngitis

This code signifies a persistent, long-term inflammation of the larynx, characterized by symptoms such as hoarseness, voice changes, and a chronic cough, lasting for an extended period (typically more than three weeks). It reflects a non-infectious or recurrent inflammatory process affecting the vocal cords and surrounding laryngeal structures.

Apply this code when documentation clearly indicates a diagnosis of chronic inflammation of the larynx. This diagnosis is typically supported by a history of prolonged laryngeal symptoms, often without an acute infectious cause, and may be confirmed by laryngoscopy findings.

• Differentiate carefully from acute laryngitis; ensure the documentation specifies "chronic" or indicates a duration exceeding the acute phase.
• Do not use for obstructive laryngitis (e.g., croup), which has a distinct code.
• Look for underlying causes of chronic laryngitis, such as GERD, vocal abuse, or environmental irritants, as these may require additional coding.
