The 2023 SEER Manual instructions contain a new note in Hematologic Transplant And Endocrine Procedure, Coding Instruction 6, regarding bilateral salpingo-oophorectomy (BSO) when performed for hormonal effect for breast, endometrial, vaginal, and other primary cancers. While we have observed BSO being performed for breast primaries, we do not recall ever seeing a statement for endometrial or vaginal primaries regarding a “BSO being done as hormonal manipulation” when scheduled either with or without a hysterectomy being performed simultaneously. As a result, we are not clear exactly when a BSO would be captured in the Hematologic Transplant And Endocrine Procedure field for these gynecologic primary sites.

Also, if these types of procedures are Hematologic Transplant And Endocrine Procedures, are they also captured and coded in the Surgery of Primary Site codes that directly relate to those same organs? Does timing have any effect on the coding of either field?

Registrars are confused because the STORE manual dropped "involved" from the description of contralateral breast removal in the Appendix B surgical codes. In April, 2019, CAnswer Forum instructed registrars to code both the surgery with uninvolved breast to the proper code, plus code Surgery of Other Site to 1. In October, they stepped back and instructed registrars not to code Surgery of Other Site to 1 if a code for uninvolved breast removal is included in the breast surgery code. However, they insist that if the surgery code is 30, subcutaneous mastectomy, and the uninvolved contralateral breast is also removed, then continue to code Surgery of Other Site to 1. This contradicts the specific instructions for Surgery of Other Sites.

Discussion: Example: Shave biopsy with superficial spreading melanoma, Breslow 0.25 mm, Clark level II. Excision with no residual melanoma and gross description of specimen size is 4.0 x 1.6 cm skin ellipse excised to a depth of 1.8 cm.

We have differing opinions in our registry.

Opinion 1: We can assume margins are greater than 1 cm based on the excision specimen size when there is no residual tumor on excision and all dimensions of the excision specimen are more than 1 cm. Surgery would be coded in 40s range.

Opinion 2: We should assume the melanoma defect was in the middle of the excision specimen, so for a skin ellipse that is 4.0 x 1.6 cm, there would be a 2 cm and 0.8 cm margin (respectively) from the middle of the specimen, thus margins are not > 1 cm. Surgery would be coded in 30s range.

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.

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)
