What 31629 covers

A pulmonologist, interventional pulmonologist, or thoracic surgeon passes a needle through a rigid or flexible bronchoscope to obtain tissue or cellular material from the tracheobronchial tree or mediastinum. Common targets include mediastinal or hilar lymph nodes and peribronchial lesions. The specimen may be sent for cytology or histopathology after bronchoscopy in a hospital or outpatient procedural setting.

Report 31629 for the initial needle-biopsy service; when additional lobes are sampled, 31633 is the related add-on code. The procedure note should identify the sampled target and lobe and describe the needle sampling performed. This is a minor procedure with 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 for an assistant at surgery, and co-surgeons and team surgery are not permitted.

31625 represents bronchoscopic biopsy of airway tissue. 31629 represents needle aspiration biopsy through the bronchoscope.
31633Bronchoscopic needle biopsy
31633 is the add-on for each additional lobe sampled by needle biopsy; 31629 reports the initial needle-biopsy service.
31652EBUS node sampling
31652 is for EBUS-guided sampling of one or two mediastinal or hilar node stations. Distinguish it from 31629 by the documented guidance and service.

31629 billing questions

How does 31629 differ from 31628?

31629 is for needle aspiration biopsy of the tracheobronchial tree or mediastinum. 31628 is for transbronchial lung biopsy, so use the code that matches the sampling method and target documented.

When is 31633 reported with 31629?

31633 is the add-on for needle biopsy in each additional lobe. The documentation should identify the additional lobe sampled; additional needle passes alone do not establish another lobe.

Should modifier 50 be appended for bilateral sampling?

No. The CMS bilateral adjustment does not apply to 31629, and modifier 50 is inappropriate.

How is 31629 distinguished from EBUS-guided node sampling?

For EBUS-guided sampling of one or two mediastinal or hilar lymph node stations, compare 31652. Select the code that reflects the documented guidance and service performed.

Does the 0-day global period include same-day care?

Yes. Same-day preoperative and postoperative care is included in the 0-day global period.

Can an assistant or co-surgeon be reported?

Medicare does not pay an assistant at surgery for 31629. 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.
