What 32555 covers

A clinician uses a needle or catheter to remove fluid from the pleural space, with imaging guidance during the procedure. Thoracentesis may be performed to obtain fluid for diagnostic testing or to relieve symptoms from an effusion. Pulmonologists, interventional radiologists, and other clinicians who perform pleural procedures commonly provide it in hospital or outpatient settings.

Report this code when imaging guidance is used for the aspiration; the record should support the pleural-fluid indication, side treated, procedure performed, and use of imaging. The same-day preoperative and postoperative care is included in its 0-day global period. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. For bilateral treatment, modifier 50 is paid at 150%. Medicare does not pay an assistant at surgery for this code, 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.

32555 billing questions

When should 32555 be chosen over 32554?

Use 32555 when imaging guidance is used during pleural-fluid aspiration. Code 32554 describes aspiration without imaging guidance.

Can imaging guidance be billed separately?

Imaging guidance is part of 32555. Do not report separate imaging guidance for that same aspiration.

How is bilateral thoracentesis reported?

For bilateral treatment, report the procedure with modifier 50; CMS pays it at 150%.

What documentation supports 32555?

Document the indication for aspiration, the side treated, the fluid-removal procedure, and that imaging guidance was used.

Does 32555 describe ongoing pleural drainage?

No. It describes aspiration of pleural fluid. Catheter-placement codes such as 32556 or 32557 apply when a catheter is inserted for drainage.

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.
