Surgical Procedure of Other Site: Is the excision of a distant lymph node or a fine needle aspirate (FNA) of a distant lymph node coded as a Surgical Procedure of Other Site, even though they are performed for diagnostic purposes and not intended as treatment?
For cases diagnosed 1/1/2003 and after: Code the Surgical Procedure of Other Site field to 3 [Non-primary surgical procedure to distant lymph nodes] for an excision of a distant lymph node because it is a surgical procedure. However, if only a fine needle aspirate of a distant lymph node is done, code this field to 0 [None].
Fine needle aspirates of regional lymph nodes are the only FNA biopsies to be coded in a surgery field (Scope of Regional Lymph Node Surgery field). In addition, FNA biopsies of regional nodes are also included in the EOD-Number of Positive Regional and Examined Lymph Nodes fields.
MP/H Rules/Recurrence: Is a subsequent diagnosis of an in situ tumor (bladder cancers excluded) a "recurrence" if it follows a prior invasive diagnosis of the original primary cancer made 5 years before?
For cases diagnosed 2007 or later, use the 2007 MP/H rules to determine whether or not a subsequent diagnosis (either invasive or in situ) is a new primary or a recurrence. Do not use the statement "recurrence" from the medical record to make this decision.
When evaluating a subsequent diagnosis and the MP/H rules indicate "single primary," the tumor being evaluated is a "recurrence" of the original primary cancer.
CS Extension--Ovary: How are the following terms coded when they are described in the medical record without any other qualifying information? Seeding, talcum powder appearance, salting, miliary, and studding.
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.Seeding, talcum powder appearance, salting and studding are synonymous with implants. When the size of implants is not stated, but operative report and scans state "seeding," "talcum powder appearance," "salting," and "studding" the CS extension code choice will depend on the location of the seeding, talcum powder appearance, salting, or studding.
The word "miliary" is not documented as a synonym for implants.
The term miliary does not affect the CS extension code choice according to the current CS instructions.
Grade/Histology--Digestive System: What is the grade for neuroendocrine tumor (NET) or neuroendocrine carcinoma (NEC) of gastrointestinal morphologies described as: 1) NET G1 (M8240/3) and NET G2 (M8249/3) or 2) neuroendocrine carcinoma, low grade (M8240/3) and neuroendocrine carcinoma, well differentiation (M8240/3) and neuroendocrine carcinoma, moderate differentiation (M8249/3)? The SEER Instructions for Coding Grade for 2014+, Coding for Solid Tumors section, #3 state: Code the grade shown below (6th digit) for specific histologic terms that imply a grade. NET and NEC are not included in the specific terms.
You may code grade as follows.
Grade 1 – NET G1 (M8240/3)
Grade 2 – NET G2 (M8249/3)
Grade 1 – neuroendocrine carcinoma, low grade (M8240/3) or neuroendocrine carcinoma, well differentiation (M8240/3)
EOD-Extension--Corpus Uteri: How is this field coded for a stage III A endometrial primary with positive pelvic washings, involvement of the omental serosa, and negative lymph nodes?
For cases diagnosed 1998-2003: Code EOD-extension as 85 [Metastasis]. According to our TNM consultant, Omental metastasis is M1, Stage IVB [EOD 85].
CS Lymph Nodes--Lung: If the lymph nodes listed in codes 10 and 20 were contralateral or bilateral, and the only description was "mass", "adenopathy", or "enlargement" on mediastinoscopy or x-ray, is this field coded to 60? See Discussion.
(CS Manual page 407) Note 2: If at mediastinoscopy/x-ray, the description is "mass", "adenopathy", or "enlargement" of any lymph nodes named as regional in codes 10 and 20, assume that at least regional lymph nodes were involved.
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.
Yes. The named nodes listed in codes 10 or 20 should be coded 60 if the "mass", "adenopathy", or "enlargement" on mediastinscopy or x-ray is described as bilateral or contralateral.
First Course Treatment/Radiation Therapy/Immunotherapy--Thyroid: For this primary, do we code I-131 as a Radio-isotope as well as a Biological Response Modifier? See Description.
(SEER Book 8 lists I-131 as a Biological Response Modifier.) Immunoglobulin is listed as immunotherapy agent in the CCR manual also coded as immunotherapy. Are there two different types of I-131, immunoglobulin and sodium iodide?
Sodium Iodide is listed as an ancillary drug in SEER Book 8, page 45. The listing on page 63 refers to Antiferritin antibody, or AntiCEA. Both of these were under clinical investigation when Book 8 was written. They are no longer active and this change will be made when Book 8 is revised.
MP/H Rules/Histology--Breast: How is the histology coded when a pre-treatment core biopsy showed ductal carcinoma, but the mastectomy specimen following neoadjuvant chemotherapy showed lobular carcinoma? See Discussion.
11/06/2012 Ultrasound-guided biopsy of the left breast and left axilla showed invasive ductal carcinoma. The patient underwent 6 months of chemotherapy. In 05/2013 the patient underwent a mastectomy that showed invasive lobular cancer, pleomorphic type, with 11 axillary lymph nodes negative.
The histology is coded to lobular carcinoma, NOS [8520/3] because the mastectomy (the most representative specimen) showed only lobular carcinoma.
The MP/H Rules state to code the histology from the most representative tumor specimen examined. Although this patient underwent neoadjuvant treatment, there is no indication that the ultrasound-guided biopsy contained more tumor than the mastectomy. The mastectomy is the most representative specimen and should be used to code the histology.
CS Tumor Size/CS Site Specific Factor 6--Breast: How are these fields coded for a tumor stated to have only in situ disease in the breast with bone metastasis identified on scan? See Discussion.
4/20/04 Quadrantectomy: "Tumor involves a significant portion of the biopsy and is estimated at 10 cm in greatest dimension." The only other mention of size is from imaging studies which is 3.5 cm. The histology is "high grade ductal carcinoma with comedo necrosis. No invasive carcinoma identified." Bone scan on 4/20/04 shows "widespread metastatic disease to bone." By rule the behavior code for this case is changed to malignant.
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.
Code tumor size as 100 [10 cm]. Size from pathology or operative report is preferred over size from imaging.
Code SSF6 as 050 [Invasive and in situ components present, size of entire tumor coded in CS Tumor Size because size of invasive component not stated and proportions of in situ and invasive not known.]
There is invasive tumor present (as proven by the bone metastasis), but the size and proportion of the invasive component is unknown.
Please note: Extension must be coded at least to 10 [Confined to the breast tissue and fat including nipple and areola; Localized, NOS] in this case. Do not assign extension code 00 [in situ].
