What 31623 covers

A pulmonologist or other qualified proceduralist advances a flexible or rigid bronchoscope into the airways and brushes a selected area to collect cells for cytology. The technique may be used when an airway abnormality, including a suspicious lesion, needs cellular evaluation. The brush specimen is distinct from tissue removed with biopsy forceps or fluid collected by washing or lavage.

Report 31623 when brushing is performed, and document the indication, sampled airway location, and collection method in the procedure record. CMS assigns this minor procedure a 0-day global period, so same-day preoperative and postoperative care is included. When related endoscopies are performed together, endoscopy family pricing applies. 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.

31623 billing questions

How is brushing different from bronchial washing or lavage?

31623 represents cell collection with a brush. Washing and lavage collect fluid specimens and are represented by 31622 and 31624, respectively.

When should 31625 be considered instead?

Use 31625 when tissue is sampled with biopsy forceps. Brushing collects cells for cytology rather than a tissue specimen.

Can brushing be reported with another bronchoscopy procedure?

The procedure report should identify each technique performed and the sampled site. CMS applies endoscopy family pricing when related endoscopies are performed together.

Should modifier 50 be appended for brushing in both lungs?

No. The CMS bilateral adjustment does not apply to 31623, 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 0-day 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.
