What 31615 covers

The clinician passes a bronchoscope through an established tracheostomy opening to inspect the trachea and bronchi. Pulmonologists, otolaryngologists, and thoracic surgeons may perform the examination in a hospital, clinic, or bedside setting to assess airway patency, investigate suspected obstruction or bleeding, or evaluate concerns involving the tracheostomy airway. The existing opening is the access route; this service does not describe creating a tracheostomy.

Report 31615 when the documented endoscopic examination is performed through that established opening. The record should identify the route and the airway evaluation performed. This minor procedure has 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% multiple-procedure reduction. Modifier 50 is inappropriate for this code. Medicare does not pay for an assistant at surgery, and co-surgeons and team surgery are not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

31615 billing questions

How does 31615 differ from 31622?

31615 describes tracheobronchoscopy through an established tracheostomy. Consider 31622 when diagnostic bronchoscopy is performed by another route and its service meets that code's requirements.

Can 31615 be reported when a new tracheostomy is created?

31615 requires an established tracheostomy opening. A tracheostomy creation service, such as 31600 or 31601, describes creating the opening rather than examining the airway through an existing one.

What should the documentation identify?

Document that the scope passed through an established tracheostomy and describe the tracheal and bronchial examination, including the clinical reason for it.

Can modifier 50 be used?

No. Bilateral adjustment is inappropriate for this code.

How do same-session procedures affect payment?

The highest-valued procedure is paid in full; other procedures in the same session are subject to the standard multiple-procedure reduction. Same-day preoperative and postoperative care is included in the 0-day global period.

Are assistant or co-surgeon claims payable?

Medicare does not pay an assistant at surgery for this service. Co-surgeons and team surgery are not permitted.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
