The National Institute for Health and Clinical Excellence (NICE) has issued full guidance to the NHS in England, Wales, Scotland and Northern Ireland on endoscopic mastectomy and endoscopic wide local excision for breast cancer.

  • Description

    Treatment for early breast cancer usually involves surgery to remove all or part of the breast. In this keyhole procedure, part or all of the breast tissue is removed using special instruments inserted through small skin incisions. The skin envelope of the breast and nipple are left intact, ready for an implant that can be inserted during the same operation. 

  • OPCS4.6 Code(s)

    The OPCS-4 codes for endoscopic wide local excision are as  follows:

    B28.2 Partial excision of breast NEC

    Includes: Wedge excision of breast NEC

                    Wide excision of breast NEC

    Y76.3 Endoscopic approach to other body cavity


    The OPCS-4 codes for endoscopic mastectomy are as  follows:

    B27.- Total excision of breast (fourth character dependent on the description of the mastectomy)

    Y76.3 Endoscopic approach to other body cavity

    Note: The codes within B27. - do not include any associate lymph node removal and these are classified with an additional code from categories T85-T87.

    In addition an ICD-10 code from category C50.- Malignant neoplasm of breast or C79.8 Secondary malignant neoplasm of other specified sites is assigned.

    The NHS Classifications Service of NHS Connecting for Health is the central definitive source for clinical coding guidance and determines the coding standards associated with the classifications (OPCS-4 and ICD-10) to be used across the NHS.   The NHS Classifications Service and NICE work collaboratively to ensure the most appropriate classification codes are provided.
