What 32400 covers
A clinician passes a needle through the chest wall to obtain pleural tissue for diagnostic evaluation. Pulmonologists, interventional radiologists, and thoracic surgeons may perform the procedure, often in a hospital setting. The target is the pleura, not a lung nodule or mediastinal mass; aspiration of pleural fluid alone is a different service.
Report this code when the needle biopsy samples pleural tissue, and document the target, percutaneous approach, and reason tissue was needed. The 0-day global period includes same-day preoperative and postoperative care. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and the others are subject to the standard 50% reduction. Modifier 50 is inappropriate for this code. Medicare does not pay an assistant at surgery, and co-surgeons and team surgery are not permitted.

How to choose
- 32408Core biopsy
- Choose 32400 for pleural tissue sampled percutaneously; choose 32408 when the needle core biopsy targets lung or mediastinal tissue.
- 32609Pleural biopsy
- This code describes percutaneous needle sampling of pleura. Code 32609 is used when pleural biopsy is performed during diagnostic thoracoscopy.
- 32555Thoracentesis
- Code 32555 describes image-guided aspiration of pleural fluid. Use 32400 when the procedure obtains pleural tissue rather than fluid.
32400 billing questions
How do I distinguish this from 32408?
Use 32400 for needle sampling of pleural tissue. Code 32408 describes percutaneous core biopsy of lung or mediastinal tissue.
Can I report this for pleural fluid removal?
No. This code is for tissue sampling. Thoracentesis codes describe pleural fluid aspiration.
Is modifier 50 appropriate for a biopsy on both sides?
No. CMS identifies bilateral adjustment as inappropriate for this code.
Can an assistant or co-surgeon be paid?
Medicare does not pay an assistant at surgery for this service. Co-surgeons and team surgery are not permitted.
What documentation supports reporting the biopsy?
Document that the target was pleura, that tissue was obtained by a percutaneous needle approach, and the clinical reason for tissue sampling.
How does the multiple-procedure reduction affect payment?
For procedures performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction.
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.
