Official Description

Nipple exploration, with or without excision of a solitary lactiferous duct or a papilloma lactiferous duct

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Nipple exploration, as described by CPT® Code 19110, is a surgical procedure aimed at diagnosing the underlying cause of bloody discharge from the nipple. This condition is often associated with a nonpalpable, benign lesion, such as a papilloma, which can obstruct the lactiferous duct. The procedure begins with the cleansing of the nipple area, followed by a gentle massage of the breast from the outer edges toward the center. This technique helps in locating the affected duct. If bloody fluid is expressed during this process, it indicates that the physician has successfully identified the problematic duct. Subsequently, the physician cannulates and dilates the duct to facilitate further examination. Once adequately dilated, a ductoscope is utilized to explore the duct and its branches for any lesions. If a lesion is detected during this exploration, both the duct and the lesion may be excised to alleviate the issue. This procedure is critical for addressing potential complications arising from duct obstructions and ensuring proper breast health.

1. Indications

The procedure described by CPT® Code 19110 is indicated for the following conditions:

  • Bloody discharge from the nipple - This symptom often prompts the need for nipple exploration to determine the underlying cause.
  • Nonpalpable benign lesions - These lesions, such as papillomas, may obstruct the lactiferous duct and lead to abnormal discharge.

2. Procedure

The nipple exploration procedure involves several key steps to ensure accurate diagnosis and treatment:

  • Cleansing of the nipple - The procedure begins with thorough cleansing of the nipple area to minimize the risk of infection and prepare the site for exploration.
  • Massage of the breast - The physician massages the breast from the periphery toward the center. This technique is essential for locating the affected duct that may be causing the discharge.
  • Expression of fluid - If bloody fluid is expressed during the massage, it indicates that the affected duct has been successfully located, confirming the need for further intervention.
  • Cannulation and dilation of the duct - The physician then cannulates the identified duct and dilates it to allow for better visualization and access during the exploration.
  • Exploration using a ductoscope - Once the duct is adequately dilated, a ductoscope is introduced to explore the duct and its branches for any lesions or abnormalities.
  • Excision of lesions - If any lesions are found during the ductoscopic exploration, the physician may proceed to excise both the duct and the identified lesion to address the underlying issue.

3. Post-Procedure

Post-procedure care following nipple exploration may include monitoring for any signs of complications, such as infection or excessive bleeding. Patients are typically advised to follow up with their healthcare provider to assess healing and discuss any further treatment options if necessary. Recovery may vary depending on the extent of the procedure and the individual patient's health status.

50 Bilateral procedure: unless otherwise identified in the listings, bilateral procedures that are performed at the same session, should be identified by adding modifier 50 to the appropriate 5 digit code. note: this modifier should not be appended to designated "add-on" codes (see appendix d).
51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
58 Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78.
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
79 Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79. (for repeat procedures on the same day, see modifier 76.)
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
