About 19110: Nipple duct exploration
Operative exploration of the nipple and lactiferous duct, often for pathologic nipple discharge, with possible removal of a solitary duct.
This service involves surgically examining the nipple and its ductal system, commonly when pathologic nipple discharge prompts operative evaluation. The surgeon may remove a solitary duct during the exploration. Breast or general surgeons typically perform the procedure in an operating-room setting to identify or treat a duct-related source of discharge; it is distinct from removing a separate breast lesion.
Report 19110 when the operative work is nipple or duct exploration, rather than needle sampling or excision of a breast lesion. The operative note should support the discharge or other indication, the nipple and side treated, the exploration performed, and any duct removed. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in one session, the highest-valued procedure is paid in full and other procedures at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment is restricted; co-surgeons and team surgery are not permitted.

19110 billing questions
When is 19110 preferable to a breast biopsy code?
Use 19110 when the surgeon operates to explore the nipple or ductal system, commonly for pathologic discharge. A breast biopsy code describes sampling breast tissue rather than nipple-duct exploration.
Can a solitary duct be removed during this service?
Yes. Removal of a solitary duct may be part of the nipple exploration; document the ductal work performed.
How should bilateral exploration be reported?
CMS lists modifier 50 for bilateral reporting, with payment at 150%. Document the procedure on both sides.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
Can an assistant or co-surgeon be paid?
CMS applies a statutory restriction on assistant-at-surgery payment for this code. Co-surgeons and team surgery are not permitted.
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 indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
