What 31633 covers
This add-on describes bronchoscopic transbronchial needle aspiration biopsy in an additional lung lobe. A pulmonologist or other qualified physician performs the sampling through a flexible or rigid bronchoscope, commonly during diagnostic evaluation of a suspected pulmonary lesion. The needle passes through the airway wall to obtain tissue or cells from the targeted site. The code distinguishes sampling in another lobe from additional needle passes or specimens taken in the same lobe.
Report 31633 with the primary bronchoscopic needle aspiration procedure, 31629, when documentation supports sampling in an additional lobe. Record the lobes sampled and the bronchoscopic needle-biopsy technique so the additional-lobe service is clear. CMS identifies 31633 as an add-on code: it is billed only with a primary procedure and 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.

31633 billing questions
Which primary procedure must accompany 31633?
Report 31633 with 31629, the primary code for bronchoscopic transbronchial needle aspiration biopsy. The record should identify the additional lobe sampled.
Does each additional needle pass support another unit?
No. The add-on is based on sampling an additional lobe, not on the number of needle passes or specimens from the same lobe.
How is 31633 different from 31632?
31633 represents needle aspiration biopsy in an additional lobe. 31632 represents additional-lobe transbronchial lung biopsy, a different sampling technique.
What documentation supports the add-on?
Document the primary needle aspiration procedure, the lobe or lobes sampled, and the needle-biopsy method. The record should distinguish the additional lobe from the lobe represented by the primary service.
Can 31633 be reported by itself?
No. CMS classifies it as an add-on code that must be billed with a primary procedure; its payment is within that 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.
