2021 SEER Manual/Surgery of Primary Site--Lung: What is the correct surgery code for a left upper lobe (LUL) wedge resection (confirming adenocarcinoma) followed by a lingular-sparing LUL lobectomy and mediastinal lymph node dissection? Is the correct Surgery Code 22 since the lingula was not resected (not the whole LUL Lung)? Or should the appropriate surgery code be 33 (this surgery suffices to code to a lobectomy with the mediastinal lymph node dissection)?
Assign code 22 for LUL wedge resection followed by a lingular-sparing LUL lobectomy and mediastinal lymph node dissection. Code the lymph node surgery in Scope of Regional Lymph Node Surgery. We obtained input from an expert who agrees with this code. He states a lingula-sparing lobectomy is best coded as a segmentectomy because it is the same as an apical trisegmentectomy.
Surgery of Primary Site--Corpus uteri: What is the correct surgery code to assign for dilation and curettage (D&C) for an in-situ endometrium (C541) primary? The code to use for the cervix uteri (C530-C539) is specified, but not for the corpus uteri (C540-C549).
Assign code 20 for endometrial D&C for in situ cancer of endometrium.
First Course Treatment/Neoadjuvant Therapy--Esophagus: Should the Neoadjuvant Therapy data item be coded as 1 or 2 when the patient completes all but one cycle of the planned neoadjuvant therapy and the managing physician notes the patient completed the neoadjuvant therapy? See Discussion.
The patient had neoadjuvant chemotherapy (Carboplatin and Paclitaxel) concurrent with radiation per the managing physician. The physician stated the patient completed the neoadjuvant therapy; however, it was also noted that patient completed five cycles of chemotherapy, but the sixth cycle was held due to neutropenia.
The SEER Manual does not address how to code Neoadjuvant Therapy when the patient completed almost all the planned neoadjuvant therapy. It seems inappropriate to code Neoadjuvant Therapy as 2 (Started but not completed) simply because the patient did not have one cycle of chemotherapy but is otherwise felt to have completed neoadjuvant therapy per the managing physician. Does the managing physician’s statement of “completion” impact how this scenario is coded?
Assign code 2, Neoadjuvant therapy started, but not completed OR unknown if completed, for the 2024 SEER Manual data item Neoadjuvant Therapy. Assign code 2 when neoadjuvant therapy was begun and the patient did not complete the full course of neoadjuvant therapy. See Coding Instruction #3 on page 230. The fact that the patient completed five cycles of the planned chemotherapy, but the sixth cycle was held due to neutropenia is important information and should be abstracted correctly and documented via text data items.
First Course Treatment/Reason for No Surgery of Primary Site: How should we be coding Reason For No Surgery of Primary Site for cases where surgery was planned but ultimately cancelled due to progression? See Discussion.
There is a discrepancy in the SEER and STORE manual definition of code 2 for Reason for No Surgery of Primary Site. STORE includes progression of tumor prior to planned surgery as part of the definition for code 2, but the SEER Manual does not. The progression statement is included in the SEER Manual (2018 and 2021) for Reason for No Radiation, but not for Reason for No Surgery.
Assign code 2 for cases where surgery was planned but ultimately cancelled due to progression in the data item Reason For No Surgery of Primary Site. Code 2 description contains examples and is not exhaustive of reasons for no surgery.
We will add the example for consistency in the next version of the SEER manual.
First Course Therapy/Surgery of Primary Site--Prostate: What is the correct surgical code for irreversible electroporation ablation of the prostate diagnosed in 2021?
Assign code 17 for irreversible electroporation ablation of the prostate when there is no tissue submitted to pathology for a 2021 or 2022 case.
EOD 2018/Heme & Lymphoid Neoplasms--Myeloid Sarcoma: How is Extent of Disease (EOD) Primary Tumor coded for a myeloid sarcoma with multifocal skin involvement? See Discussion.
Patient has a diagnosis of myeloid sarcoma presenting as multiple erythematous papules and nodules on back, chest, right arm & shoulder. Oncologist did not mention any evidence or suspicion of an associated AML diagnosis.
HemeRetic schema EOD Primary Tumor Note 1 states that myeloid sarcoma can be coded as localized (code 100) or systemic (code 700). It is not clear what would qualify as systemic disease for myeloid sarcoma.
Assign code 100, localized, using the 2018 EOD Primary Tumor, HemeRetic schema, for the myeloid sarcoma with skin involvement since only the skin is involved. Use code 700, distant or disseminated, when multiple organs are involved.
SEER Manual/Surgery of Primary Site 2023--Breast: What instructions should be followed when the 2023 SEER Manual Appendix C 2023 Breast Surgery Codes advise to code 1 in Surgical Procedure of Other Site for a simple bilateral mastectomy but the 2023 STORE Manual does not. See Discussion.
The 2023 SEER Manual, Appendix C 2023 Breast Surgery Codes, note reads:
SEER Note: Assign code A760 for a more extensive bilateral mastectomy. Assign code 0 in Surgical Procedure of Other Site (NAACCR #1294). For a simple bilateral mastectomy, assign code A410 with code 1 in Surgical Procedure of Other Site (NAACCR #1294).
In the 2023 STORE Manual, these notes are not mentioned and we are instructed not to code surgery to other site. Other education related to 2023 breast coding provided by NAACCR states to not code surgery to other site.
Assign code 1 in Surgical Procedure of Other Site (NAACCR #1294) when a simple bilateral mastectomy is performed for a single tumor involving both breasts. This statement was inadvertently omitted from the STORE manual and will be added back in: For single primaries only, code removal of contralateral breast under the data item Surgical Procedure/Other Site (NAACCR Item #1294) or Surgical Procedure/Other Site at This Facility (NAACCR Item #674).
The information presented by NAACCR was intended to be consistent with what is in the SEER manual. It may have been misuderstood.
Diagnostic Confirmation--Leukemia: How is this field coded when the clinician confirms that the diagnosis of CML is based on a combination of the clinical picture and positive cytogenetic studies?
Assign code 1 [Positive histology]. For leukemia only, assign code 1 for positive hematologic findings including peripheral blood smears, CBCs and WBCs.
Cytogenetics studies would have been done on blood. Therefore, histology provided diagnostic confirmation as it would with smear, bone marrow, or other special study of blood cells.
Diagnostic Confirmation--Hematopoietic, NOS: Is a multiple myeloma diagnosed by an FNA of the lumbar spine (or any other non-bone marrow location) a diagnostic confirmation 1 or 2? See Description.
Does the rule on page 111 of the SEER Program Coding Manual, 3rd Edition, for code 1 apply to myelomas (in the same way it applies to leukemias)?
Assign code 1 [Positive histology] for aspiration of bone marrow. This rule is not limited to leukemias.
