What 31632 covers
A pulmonologist, interventional pulmonologist, or thoracic surgeon may take transbronchial lung tissue samples through a bronchoscope to evaluate findings such as pulmonary nodules or diffuse lung disease. This add-on represents sampling in an additional lobe beyond the lobe reported with the primary transbronchial lung biopsy service. It is commonly performed in a hospital bronchoscopy suite or operating room.
Report 31632 with 31628 when the bronchoscopist biopsies lung tissue in one or more additional lobes during the same procedure. The operative report should identify the lobes sampled and describe transbronchial lung tissue biopsy; the additional code is based on the additional lobe, not the number of specimens or biopsy passes. CMS classifies it as an add-on: it must be billed with a primary procedure and is paid within that procedure’s global period.
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.

31632 billing questions
Can 31632 be reported by itself?
No. It is an add-on code and must be reported with the primary transbronchial lung biopsy code, 31628.
Is 31632 reported for each extra specimen or biopsy pass?
No. It represents transbronchial lung biopsy in an additional lobe. Document the lobe sampled; specimen or pass count alone does not establish another unit.
How does 31632 differ from 31628?
31628 reports transbronchial lung biopsy in the primary lobe. Use 31632 for biopsy sampling in each additional lobe during that procedure.
When should 31625 be considered instead?
31625 concerns bronchoscopic biopsy of airway tissue, such as a bronchial lesion. 31632 applies to transbronchial sampling of lung tissue in an additional lobe.
What documentation supports reporting 31632?
The bronchoscopy report should state that transbronchial lung tissue was sampled and identify the additional lobe or lobes biopsied.
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.
