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.

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.

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.
