Unspecified open wound of larynx, sequela

This code signifies a long-term complication or late effect resulting from an unspecified open wound to the larynx. It indicates that the initial injury has healed, but the patient continues to experience residual issues directly attributable to that past laryngeal trauma.

Use this code when documentation clearly links a current laryngeal condition to a previously sustained open wound of the larynx, and the specific nature of the original wound is not detailed. This applies to conditions like chronic hoarseness, scarring, or airway obstruction that are sequelae of the initial injury.

• Always assign a sequela code when the residual effect of an old injury is being treated.
• Do not use this code for acute open laryngeal wounds; those require acute injury codes.
• Ensure documentation explicitly states the current condition is a "sequela," "late effect," or "due to old injury" of the larynx.
