Acquired absence of larynx

This code indicates the complete removal or loss of the voice box (larynx) after birth. This condition results in the inability to speak naturally and often necessitates the use of alternative communication methods.

Use this code for patients who have undergone a total laryngectomy, typically due to laryngeal cancer, severe trauma, or other medical conditions requiring the surgical removal of the larynx. It should be assigned as a secondary diagnosis to explain the patient's current anatomical status.

• Always code the underlying reason for the laryngectomy (e.g., malignancy) as the primary diagnosis, if applicable and still active.
• Do not use this code for congenital absence of the larynx; a different code would be appropriate for a birth defect.
• Consider additional codes for any associated conditions, such as tracheostomy dependence or speech impairment.
