What 32998 covers

Code 32998 covers percutaneous radiofrequency treatment intended to destroy or reduce one or more lung tumors. An interventional radiologist or thoracic specialist typically advances an RF probe through the chest wall into the target, often using CT or other imaging. It is performed in a procedural setting for selected patients with a primary lung tumor or pulmonary metastasis; imaging guidance, when performed, is included in the service.

Report this code for radiofrequency ablation, not cryoablation or a diagnostic needle biopsy. One service covers one or more tumors treated during the procedure; document the targets, laterality, percutaneous approach, and RF technique. The 0-day global period includes same-day preoperative and postoperative care. When multiple procedures occur in one session, the highest-valued procedure is paid in full and the others at 50%. Bilateral treatment with modifier 50 is paid at 150%. An assistant at surgery may be paid; 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.

32998 billing questions

When should 32998 be chosen instead of 32994?

Use 32998 for percutaneous radiofrequency ablation of pulmonary tumor tissue. Code 32994 describes the cryoablation method.

Can imaging guidance be billed separately?

Imaging guidance, when performed for the ablation, is included in 32998. Do not separately report guidance for that same service.

How should bilateral lung treatment be reported?

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

Does the number of tumors determine the units?

The code covers treatment of one or more pulmonary tumors. Document the treated targets and do not assign units solely by counting tumors.

What documentation supports reporting 32998?

Document the pulmonary tumor targets, laterality, percutaneous approach, use of radiofrequency, and imaging guidance when performed.

How are other procedures in the same session paid?

Under the standard multiple procedure reduction, the highest-valued procedure is paid in full and other procedures are paid at 50%.

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.
