What 38740 covers

Code 38740 represents operative removal of superficial lymph nodes in the axilla as a regional dissection, rather than sampling one or a few targeted nodes. A breast surgeon or surgical oncologist commonly performs it in a hospital operating room during treatment of breast cancer or another malignancy involving the axillary basin. The operative report should identify the side and describe the nodal tissue and extent removed; sentinel-node excision alone is a different service.

Report 38740 when documentation supports superficial axillary lymphadenectomy; 38745 describes a complete axillary dissection, while 38525 is used for open excision of deep axillary nodes. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in one session, the highest-valued procedure is paid in full and others at 50%. For bilateral service, modifier 50 is paid at 150%. An assistant at surgery may be paid; co-surgeons require supporting documentation, and team surgery 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.

How to choose

38745Axillary dissection

38525Axillary node biopsy
Use 38525 for open excision of deep axillary node(s), such as targeted node sampling, rather than a superficial regional dissection.
19302Partial mastectomy
This partial mastectomy code includes axillary lymphadenectomy. Do not separately report 38740 for the same dissection included in that procedure.

38740 billing questions

How do I distinguish 38740 from 38745?

Use 38740 for a superficial axillary nodal dissection. Use 38745 when the operative work is a complete axillary dissection.

Is sentinel-node biopsy reported with 38740?

An isolated targeted deep axillary node excision, such as sentinel-node sampling, is generally reported with 38525 rather than as a regional dissection under 38740.

Can 38740 be reported separately with a partial mastectomy?

Code 19302 describes partial mastectomy that includes axillary lymphadenectomy. Do not separately report 38740 for the same dissection included in that service.

How is bilateral axillary dissection handled?

For procedures on both axillae, CMS pays modifier 50 at 150%. The operative documentation should support work on each side.

What postoperative care is included?

The 90-day global includes the day-before preoperative visit and 90 days of related postoperative care.

Can an assistant or co-surgeon be reported?

An assistant at surgery may be paid. Co-surgeon payment requires supporting documentation; team surgery is not permitted.

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.
