What 31643 covers
A pulmonologist or interventional pulmonologist uses a rigid or flexible bronchoscope to guide a catheter through the airway for delivery of a radiopharmaceutical agent. The service is used in situations such as endobronchial brachytherapy for a lung tumor; the catheter placement is distinct from the subsequent radiation treatment. It is generally performed in a hospital or other facility equipped for therapeutic bronchoscopy and radiation procedures.
Report 31643 when the bronchoscopic catheter placement for agent delivery is performed. The procedure note should identify the catheter placement and its intended delivery purpose; a diagnostic airway inspection alone is not enough. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures are performed in one 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. Medicare does not pay an assistant at surgery for this service; 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.

31643 billing questions
How is 31643 different from diagnostic bronchoscopy?
31643 requires bronchoscopic catheter placement for delivery of a radiopharmaceutical agent. A diagnostic airway examination without that placement is not 31643.
Can diagnostic bronchoscopy be reported separately for the same airway inspection?
The bronchoscopic access and inspection used to place the catheter are part of 31643. Do not separately report a diagnostic bronchoscopy code for that same work.
Is modifier 50 appropriate?
No. CMS identifies bilateral adjustment as inappropriate for this code, so modifier 50 should not be used.
How does the 0-day global period affect same-day care?
Same-day preoperative and postoperative care is included in the procedure's 0-day global period.
What happens if another procedure is performed in the same session?
Under the standard multiple-procedure reduction, the highest-valued procedure is paid in full and other procedures are paid at 50%. Medicare does not pay an assistant at surgery, and 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.
