About 31605: Emergency transtracheal surgical airway
Reports emergency surgical airway access through the cricothyroid region when an acute obstruction requires transtracheal airway access.
This service creates emergency airway access through the cricothyroid membrane, commonly called a cricothyrotomy. It is used when a patient has an acute, critical airway problem and an airway cannot be secured by less invasive means. The procedure is typically performed by a physician in an emergency department, operating room, or other acute-care setting; the opening may provide temporary access for ventilation.
Report 31605 for the emergency transtracheal approach, not a planned tracheostomy or an emergency opening lower in the neck. Documentation should establish the airway emergency, the need for surgical access, and the transtracheal approach. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others at 50%. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this service; co-surgeons and team surgery are not permitted.

31605 billing questions
How do I distinguish 31605 from 31603?

31605 describes emergency transtracheal airway access. A planned tracheostomy is reported with 31600, or 31601 for a patient younger than 2 years.
Can modifier 50 be reported?
No. CMS identifies bilateral adjustment as inappropriate for this code; do not append modifier 50.
