Surgery text indicates TAH-BSO with bilateral pelvic and paraaortic lymph node dissection. The pathology report indicates the specimen includes: Uterine corpus, cervix, bilateral ovaries and fallopian tubes, bilateral parametria. The Gross Description also indicates: Representative sections submitted in 16 cassettes as follows: A1: Anterior cervix A2: Posterior cervix A3: Full thickness anterior lower uterine segment A4: Full thickness posterior lower uterine segment A5: Tumor A6-A7: Full thickness anterior endomyometrium to include tumor A8-A10: Full thickness posterior endomyometrium with tumor A11: Representative sections of right fallopian tube and fimbria A12: Representative sections of right ovary A13: Representative sections of left fallopian tube and fimbria A14: Representative sections of left ovary A15: Right parametrial tissue A16: Left parametrial tissue A17-23: Remainder of cervix.

Since acellular dermal matrix/AlloDerm comes from human tissue donors with cells removed and sterilized to promote regenesis and decrease rejection, is Alloderm coded as "Tissue' as it also "provides an additional layer of tissue between the skin and the implant?

Pt diagnosed with rt breast primary opted to be treated with rt modified radical mastectomy and lt simple mastectomy. Path revealed invasive ductal carcinoma on the rt and ductal carcinoma in situ on the lt. Path reported 14 axillary lymph nodes were found in the mastectomy specimen.

Procedure stated = Bilateral skin-sparing mastectomies, left axillary sentinel lymph node biopsy. On the pathology report it indicates two additional lymph nodes were removed that were not SLN. The axillary aspect measures 2 x 2 x 1 cm. Two lymph nodes are identified ranging from 0.5 up to 1 cm. The lymph nodes are bisected and entirely submitted. Final Diagnosis Left breast, mastectomy including nipple: no residual carcinoma; FINAL DIAGNOSIS for LN = Lymph nodes, left axillary sentinel #1; excision: Two lymph nodes examined - negative for tumor (0/2); Two lymph nodes - negative for tumor (0/2)

In the past, the SEER Manual indicated that code 30 [subcutaneous mastectomies], which captured nipple-sparing mastectomies, would rarely be used because it was not typically performed as treatment for a malignancy. This note was removed from the 2010 SEER Manual, Appendix C. Code 30 which now states, "A subcutaneous mastectomy is the removal of breast tissue without the nipple and areolar complex or overlying skin." More "nipple-sparing mastectomies" are now being performed at certain facilities.

Should the Surgery of Primary Site field be coded to 30 when a nipple-sparing mastectomy with reconstruction is performed, even if there is skin removal? Or, does the skin removal indicate that this is not a subcutaneous mastectomy, and therefore code 43 [Total (simple) mastectomy with reconstruction, NOS] applies?

In Appendix C- Breast (SEER Manual 2015) it states under the codes for TOTAL MASTECTOMY (Codes 40-49, 75): For single primaries only, code removal of involved contralateral breast under the data item Surgical Procedure/Other Site (NAACCR Item # 1294). [SEER Note: Example of single primary with removal of involved contralateral breast--Inflammatory carcinoma involving both breasts. Bilateral simple mastectomies. Code Surgery of Primary Site 41 and code Surgical Procedure of Other Site 1.] HOWEVER, underneath that it states code 76 is used for: 76 Bilateral mastectomy for a single tumor involving both breasts, as for bilateral inflammatory carcinoma. So

Operative report indicates a wire localized lumpectomy was performed. The pathology report includes a final diagnosis for two specimens as follows:

A) LEFT BREAST, EXCISION: INFILTRATING DUCTAL CARCINOMA

B) LEFT BREAST, NEW DEEP MARGIN, EXCISION: BENIGN BREAST TISSUES AND BENIGN FIBROFATTY SOFT TISSUES; NO EVIDENCE OF NEOPLASIA.

The definition for Breast surgery code 23 is "Reexcision of the biopsy site for gross or microscopic residual disease". There is no indication whether the re-excision has to be a separate procedure or can be during the same procedure as the excisional biopsy (lumpectomy). Some hospital registrars in our region believe code 22 is more appropriate.
