About 31720: Initial tracheobronchial airway clearance
Reports initial therapeutic suctioning of the tracheobronchial tree to clear obstructing secretions or other material without bronchoscopic aspiration.
This service clears the tracheobronchial tree by therapeutic aspiration, commonly when retained mucus or other material is impairing airway patency or ventilation. A physician or other qualified practitioner may perform it at the bedside or in another acute-care setting, using an aspiration catheter through an artificial airway or by another appropriate nonbronchoscopic route. The clinical record should identify the airway problem, the material removed, and the therapeutic need for aspiration.
Use 31720 for the initial airway-clearance service; 31725 represents a subsequent service. The record should make clear which service was performed rather than counting each catheter pass as a separate encounter. The 0-day global period includes same-day preoperative and postoperative care. When multiple procedures occur in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this service, and co-surgeon and team-surgery reporting are not permitted.

31720 billing questions
When should 31720 be reported instead of 31725?
Use 31720 for the initial therapeutic aspiration service and 31725 for a subsequent service. Documentation should distinguish the services performed.
How is this different from bronchoscopic aspiration?
31720 describes therapeutic airway clearance without bronchoscopic aspiration. When the therapeutic aspiration is performed through a bronchoscope, consider the bronchoscopic service represented by 31645 or 31646, as appropriate.
Can each catheter pass be billed as a separate unit?
The code identifies an initial airway-clearance service, not an individual catheter pass. Document the therapeutic service and the airway problem being treated.
Does modifier 50 apply when both sides are cleared?
No. Modifier 50 is inappropriate for this airway-clearance service.
How are other procedures in the same session paid?
The highest-valued procedure is paid in full, and other procedures in that session are subject to the standard multiple-procedure reduction. Same-day preoperative and postoperative care is included in the 0-day global period.
Can an assistant, co-surgeon, or surgical team be reported?
Medicare does not pay an assistant at surgery for 31720. Co-surgeons and team surgery are not permitted.
