What 31646 covers
During bronchoscopy, the physician or other qualified practitioner uses suction through a flexible or rigid scope to clear additional secretions or mucus from the tracheobronchial tree. This may be needed when retained secretions or mucus plugging continue to obstruct the airways after an initial therapeutic aspiration. The service is commonly performed by a pulmonologist or thoracic surgeon in a hospital or other facility setting.
Report this code for a subsequent therapeutic aspiration in the same session, with the initial aspiration reported separately using 31645. Document the clinical reason for further airway clearance and the subsequent aspiration performed. The 0-day global period includes same-day preoperative and postoperative care. 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% reduction. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this service, and co-surgeons and team surgery are not permitted.

31646 billing questions
When is 31646 reported instead of 31645?
Use 31645 for the initial therapeutic aspiration during the bronchoscopy session. Report 31646 for a subsequent therapeutic aspiration in that same session.
Does 31646 require 31645 on the claim?
Yes. The initial therapeutic aspiration is reported with 31645; 31646 describes the subsequent aspiration service.
Can routine suctioning during bronchoscopy support 31646?
Document the clinical need for further airway clearance and the subsequent therapeutic aspiration performed. Routine suctioning alone does not establish a subsequent therapeutic service.
Should modifier 50 be appended?
No. The service is not reported bilaterally, and modifier 50 is inappropriate.
How does the 0-day global period affect same-day care?
Same-day preoperative and postoperative care is included in the procedure's global period.
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.
