What 31603 covers

This service establishes an airway through a surgical opening in the trachea during an emergency. It is distinct from an emergency opening through the cricothyroid membrane. An ENT, trauma, or other qualified surgeon may perform it in a hospital emergency department or operating room when the patient needs an urgent surgical airway, such as when an airway cannot be secured by other means.

Report 31603 for the emergency tracheostomy performed, not for a planned tracheostomy or an emergency cricothyroidotomy. The operative record should support the emergency circumstances and identify the procedure performed and the airway site. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment is restricted, and co-surgeon and team-surgery billing are not permitted.
