Laryngeal spasm

This code represents an involuntary, sudden contraction of the laryngeal muscles, leading to a temporary narrowing or closure of the glottis. This spasm can cause difficulty breathing, stridor, and a sensation of choking. It is often a transient and self-limiting event.

Use this code when documentation clearly indicates a diagnosis of laryngeal spasm, whether idiopathic or secondary to irritants, anxiety, or other underlying conditions. It is appropriate for acute episodes of vocal cord adduction causing airway obstruction.

• Differentiate from laryngismus stridulus, which is typically seen in children and often associated with hypocalcemia.
• Consider additional codes for any underlying cause or associated symptoms, such as GERD or anxiety.
• Ensure documentation specifies "spasm" and not just general laryngeal irritation or inflammation.
