What 21601 covers

This operation removes a chest-wall tumor together with involved rib tissue, rather than removing a rib as an isolated procedure. Thoracic or oncologic surgeons perform it in an operating room, commonly for a primary chest-wall mass or a lesion requiring removal of both tumor and rib tissue. The operative field may include adjacent soft tissue; the defining service is tumor excision that includes rib removal.

Report the code when the operative report supports chest-wall tumor excision with rib resection, and document the tumor site, tissues removed, and ribs involved. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in one session, Medicare pays the highest-valued procedure in full and other procedures at 50%. Do not use modifier 50 for bilateral reporting. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team-surgery payment is 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.

21601 billing questions

How does this differ from 21600?

21601 describes removal of a chest-wall tumor that includes rib resection. Code 21600 describes partial rib removal as the procedure, without the chest-wall tumor excision represented by 21601.

Are the ribs separately billable with the tumor excision?

Do not separately report rib removal that is part of the chest-wall tumor excision. The operative report should identify the tumor and the rib tissue removed.

When should 21602 or 21603 be considered?

Those neighboring codes identify chest-wall tumor excision according to lymphadenectomy status. Use the code whose descriptor matches the procedure documented, including whether lymphadenectomy was performed.

Can modifier 50 be used for bilateral procedures?

No. The descriptor and anatomy make modifier 50 inappropriate for this service.

How are assistant and co-surgeon claims handled?

An assistant at surgery may be paid. Co-surgeon payment requires supporting documentation; Medicare does not permit team-surgery payment for this code.

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.
