20190074 | First course treatment/Scope of Reg LN Surgery--Breast: How is Scope of Regional Lymph Node Surgery coded when there is a sentinel lymph node biopsy (SLNBx) and intra-mammary nodes removed for a single primary? See Discussion. |
Example: Operative report documents a left breast skin sparing mastectomy and sentinel node biopsy procedure. Pathology report lists left axillary sentinel nodes in specimen A) with 0/2 nodes positive, and left breast mastectomy without axilla in specimen B) yielding an additional 0/2 intramammary nodes positive. Would the Scope of Regional Node Surgery be coded as 2 (SLN biopsy) to capture the intent of the sentinel node procedure only, or 6 (code 2 + 4) to capture the actual type and number of nodes removed? SEER Coding and Staging Manual includes Scope of Regional Lymph Node Surgery instruction 4.b. which mentions assigning code 4 to intra-organ node removal. Similarly, there is instruction for coding SLN biopsy as code 2 and SLN biopsy with axillary dissection at the same time (code 6) or during separate procedures (code 7). However, it is not clear this combination code is how we should also capture an incidental intra-organ node removal. |
Revised answer 07/11/2023 Assign code 6, Sentinel node biopsy and code 3, 4, or 5 at same time or timing not noted. There were two sentinel lymph nodes removed (code 2) plus two intramammary nodes removed in a separate specimen from the mastectomy (code 4). Assign code 6 when nodes are removed from a sentinel lymph node procedure at the same time as removal of intra-organ lymph nodes which were not part of the sentinel lymph node procedure. |

20190064 | Multiple Primaries--Heme & Lymphoid Neoplasms: Patient is diagnosed with myelodysplastic syndrome (MDS) with an early/evolving acute myeloid leukemia (AML) thought to be treatment related. Does rule M11 apply since there are two biopsies within 21 days, and therefore, two primaries, or one primary (9920/3)? See Discussion. |
Patient has a history of breast cancer and diffuse large B-cell lymphoma (DLBCL), both treated with chemotherapy and radiation. On 6/26/19, bone marrow biopsy: MDS with excess blasts-2 (18% dysplastic blasts) in a normocellular marrow (overall 40% cellularity) with trilineage dysplasia. Comment: least myelodysplastic syndrome with excess blasts-2. However, an early/evolving AML cannot be completely excluded. The findings likely represent therapy-related myeloid neoplasm. MD note on 7/15/19: Diagnosis: MDS, high grade borderline AML with complex karyotype secondary disease. Patient has high grade MDS which is bordering on AML transformation with 20% blasts by IHC and areas higher than this. This is likely secondary to the treatment she has received for her other cancers particularly pelvic radiation for her DLBCL. Given her very high IPSS score, it is likely she will eventually develop AML. No treatment given. On 7/15/19, bone marrow biopsy: Persistent acute leukemia in a marrow with trilineage dyspoiesis and 23% blasts. |
Code as one primary (9920/3). This case does not fit the rules very well, since it is a treatment-related neoplasm and involves a transformation of MDS to AML during the clinical workup. Per the abstractor notes for 9920/3, code 9920/3 when the physician comments that the neoplasm is treatment related. This can be for the MDS or the AML. Use text fields to document that it was first referred to as MDS and then transformed to AML. If you followed the rules strictly and coded this as two primaries (the MDS and AML), you would lose the information that this was treatment related, which is more important. |

20190072 | Solid Tumor Rules (2018)/Histology--Lung: What is the correct histology code for minimally invasive adenocarcinoma in the lung, 8140/3 or 8256/3? See Discussion. |
For example, 9/12/18 left lung upper lobe lobectomy: 1.5 cm, 0.8 cm invasive component, lepidic predominant adenocarcinoma with acinar and lepidic patterns, G2, no visceral pleural invasion, no LVI, 0/14 LNS positive. An additional minimally invasive adenocarcinoma, 1 mm, was seen away from the main tumor. The correct coding of the minimally invasive adenocarcinoma will ultimately determine if we have one tumor (using rule M7) versus two primaries (using rule M6). |
Updated answer: Code minimally invasive adenocarcinoma, NOS as 8140/3. This is a new term and code in the 2018 ICD-O-3 New Codes, Behaviors, and Terms-Updated 8/22/18 list. See Solid Tumor Lung Table 3, and Solid Tumor Lung rules H1 and H10. |

20190047 | Reportability/Liver: If on imaging, there is no statement of the Liver Imaging Reporting and Data System (LI-RADS) score but there is reference that a lesion is in the Organ Procurement and Transplantation Network (OPTN) 5 category, is hepatocellular carcinoma (HCC) reportable based on the OPTN 5 classification? See Discussion. |
SINQ 20160008 discusses the reportabilty and diagnosis date for liver primaries where imaging references the LI-RADS category as LR-5 or LR-5V. The 2018 SEER Coding and Staging Manual, Appendix E Reportable Example #16, demonstrates this concept. According to the LI-RADS categories a value of 5 is "definitely HCC" and is concordant with OPTN 5. Often we see only the OPTN categorization. |
Report HCC based on the OPTN class of 5. OPTN class 5 indicates that a nodule meets radiologic criteria for HCC. Be sure to document in text fields. |

20190001 | EOD 2018/Summary Stage 2018--Brain and CNS: What are the Extent of Disease (EOD) Primary Tumor, EOD Reg Nodes, and Summary Stage 2018 codes for intradural schwannoma of the lumbar spine (L2-L4)? See Discussion. |
Example: Patient diagnosed following a resection of a cystic mass at L2-4 that proved an intradural tumor excision with final diagnosis of schwannoma, WHO grade 1. Per new Solid Tumor Rules, the primary site in this case should be coded C476 (peripheral nerves of trunk, NOS) and histology is 9560/0 (schwannoma, NOS). However, there are currently no coding options in the Soft Tissue of Trunk and Extremities EOD schema relating to a benign tumor. Likewise there are no coding options in the Soft Tissue and Sarcoma Summary Stage 2018 schema relating to a benign tumor. How should EOD 2018 and Summary Stage 2018 be coded for reportable benign schwannomas of the spinal nerve roots? |
The instruction regarding C476 has been removed from the Solid Tumor rules. Benign and borderline neoplasms coded to C470-C479 are not reportable at this time. Assign C720 for an intradural schwannoma at L2-4. That should allow you to use the correct EOD and Summary Stage 2018 schemas. |

20190039 | Solid Tumor Rules (2018)/Histology--Lung: What is the histology code of invasive moderately differentiated adenocarcinoma, predominantly papillary subtype, with minor acinar and lepidic subtypes? See Discussion. |
11/01/2018, lung, left upper lobe, wedge resection: Invasive moderately differentiated adenocarcinoma, predominantly papillary subtype, with minor acinar and lepidic subtypes. Would this be 8260/3 since the acinar and lepidic subtypes are described as minor or would this be 8255/3 because there is papillary plus two other subtypes/variants described as subtypes? |
Code as adenocarcinoma, papillary predominant (8260/3) according to the Lung Solid Tumor Rules, Coding Multiple Histologies, which says to code the specific histology. The most specific histology may be described as component, majority/majority of, or predominantly, where predominantly describes the greater amount of tumor. |

20190058 | Solid Tumor Rules (2018)/Histology--Cervix Uteri: What is the histology code and what H Rule applies for a diagnosis of papillary squamotransitional cell carcinoma of the cervix? See Discussion. |
It appears that the first Other Sites applicable rule is H16 (and Table 2) instructing the use of histology code 8323 (mixed cell adenocarcinoma). However, this really is not an adenocarcinoma tumor but is a mixed squamous and transitional cell carcinoma. The 2018 ICD-O-3 Histology Update Table provides a new term for a but does not indicate whether that new term would also include a papillary squamotransitional cell carcinoma of the cervix. |
Code papillary squamotransitional cell carcinoma (PSCC) as 8120/3 using the 2018 Other Sites Solid Tumor Rules, Rule H11. PSCC is a distinctive subcategory of squamous cell carcinoma of the uterine cervix. WHO Classification of Tumors of Female Reproductive Organs say that squamotransitional cell tumors show papillary architecture with fibrovascular cores lines by multilayered atypical epithelium. |

20190044 | Solid Tumor Rules (2018)/Histology--Colon: Is the term phenotype equivalent to type, subtype, variant for the purpose of coding histology? See Discussion. |
In our region, pathologists often describe histology using the term phenotype. However, the use of the term phenotype is not discussed in the Solid Tumor Manual. Example: Final Diagnosis of a colon tumor is invasive adenocarcinoma with a mixed phenotype, and the Diagnosis Comment states: The majority of the disease is poorly differentiated/signet ring cell phenotype. Would the histology be coded to 8490 (signet ring cell carcinoma), if the majority of the tumor is a more specific histology described by the term phenotype? |
While variant, type, and subtype can be used interchangeably according to the Solid Tumor Rules, SINQ 20170058 states that the Multiple Primaries/Histology (now Solid Tumor) Rules do not include coding phenotype. Code as invasive adenocarcinoma NOS (8140). |

20190014 | Reportability--Behavior: Is reportable if it shows invasion or microinvasion pathologically? See Discussion. |
The SEER Manual states, Generally, this rule is invoking the Matrix principle in the ICD-O-3. We are aware this is not the same as a VIN III or an adenoma with microinvasion because those tumors have a valid histology code listed in the ICD-O-3. The terms or or do not have a valid ICD-O-3 code to apply the Matrix principle. If severe dysplasia is felt to be consistent with a carcinoma in situ, then a severe dysplasia with microinvasion would be reportable as 8010/3. But in the U.S., we do not accession severe dysplasia as equivalent to carcinoma in situ unless the pathologist also states the severe dysplasia is equivalent to carcinoma in situ (e.g., ). |
Severe dysplasia alone is not reportable. No further instructions apply because this term is not reportable.In order to use the instructions for behavior, you must first have a reportable neoplasm. If carcinoma in situ is mentioned and there is microinvasion, code the behavior as /3 according to the instructions in the SEER manual. You are correct, do not accession severe dysplasia as equivalent to carcinoma in situ unless the pathologist also states the severe dysplasia is equivalent to carcinoma in situ (e.g., ). |

20190057 | Reportability/Histology--Penis: Are and (PeIN) equivalent to PeIN3 and thus reportable? See Discussion. |
Appendix E1 of the 2018 SEER manual references a similar diagnosis as being reportable for vulva and vagina only. However, the WHO Classification of Tumors of the Urinary System and Male Genital Organs (4th ed) does include high grade penile intraepithelial neoplasia as a synonym for 8077/2. |
Penile intraepithelial neoplasia, grade III (PeIN III) and squamous cell carcinoma in situ of the penis are reportable. If possible, query the physicians as to whether "high grade penile intraepithelial lesion" or are synonymous with one of the reportable terms. If no further information can be obtained, report the case as C609 8077/2, and use text fields to document the details. |
