What 38500 covers

Code 38500 describes open sampling or removal of one or more superficial lymph nodes through a surgical incision. The surgeon exposes the node directly and removes all or part of it for pathologic evaluation. It is used when an accessible superficial node needs tissue diagnosis or excision, rather than needle sampling or removal from a deep nodal basin. Surgeons commonly perform this service in hospital outpatient departments and ambulatory surgery settings; office performance is also represented in Medicare claims.

Select the code based on the open approach and superficial location, not solely on the diagnosis or pathology result. The operative report should identify the site, approach, and whether the node was sampled or removed, and the record should support the clinical reason for obtaining tissue. Related postoperative visits during the 10-day global period are included. 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 reporting with modifier 50, CMS payment is 150%. Assistant-at-surgery payment is restricted; 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.

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.
