What 31625 covers

A pulmonologist or other qualified physician passes a bronchoscope into the airways and obtains tissue from an abnormal area, commonly with biopsy forceps. Typical targets include a visible bronchial mass, irregular mucosa, or another airway lesion requiring histologic evaluation. The procedure is commonly performed in a hospital bronchoscopy suite or an outpatient procedural setting, with sedation or anesthesia as clinically appropriate.

Choose this code for biopsy of airway tissue; transbronchial sampling of lung parenchyma is represented by a different code. The report should identify the biopsy site and describe the abnormality sampled and the tissue obtained. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When related endoscopies are performed in the same session, endoscopy-family pricing applies. Modifier 50 is inappropriate for this code. Medicare does not pay 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.

How to choose

31628Lung biopsySingle lobe
The biopsy target determines the choice: 31625 is for airway tissue, while 31628 is for transbronchial lung tissue.
31622BronchoscopyDiagnostic with washing
31622 describes diagnostic bronchoscopy without the airway tissue biopsy reported with 31625.
31623BronchoscopyBrush cytology
31623 collects cells by brushing; 31625 obtains tissue from an airway abnormality.
31629Bronchoscopic biopsyNeedle aspiration biopsy
31629 describes needle aspiration sampling, rather than the airway tissue biopsy reported with 31625.

31625 billing questions

When should this code be chosen instead of 31628?

Use this code for tissue taken from an airway lesion or mucosa. Code 31628 applies to transbronchial biopsy of lung tissue.

Can diagnostic bronchoscopy also be reported?

The airway inspection needed to locate and obtain the biopsy is part of the biopsy service. CMS endoscopy-family pricing applies when related endoscopies are performed together.

What documentation supports the biopsy?

Document the airway site, the abnormal finding sampled, and that tissue was obtained for evaluation. Distinguish an airway biopsy from sampling of lung parenchyma.

Should modifier 50 be appended for biopsies on both sides?

No. CMS identifies bilateral adjustment as inapplicable because the code descriptor or anatomy makes modifier 50 inappropriate.

Can an assistant or co-surgeon be reported?

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.
