First Course Treatment--Thyroid: Is hormone replacement following total thyroidectomy coded as first course treatment for all thyroid cases?
Code Hormone therapy as 01 [Hormone therapy administered as first course therapy] when thyroid replacement therapy is part of the first course of treatment for follicular or papillary thyroid cancer following thyroidectomy.
Thyroid hormone replacement therapy has a treatment effect on differentiated (follicular and papillary) carcinomas of the thyroid. This treatment effect is not seen for most medullary and undifferentiated thyroid cancers.
Radiation: How would this field be coded for treatment with quadramet [radioactive samarium]? See Description.
Paitent is receiving quadramet for treatment of lung metastases.
Code Quadramet in the RX Summ-Radiation field as 3 [Radioisotopes]. Quadramet is a radioisotope used to palliate bone pain. The instructions in the SEER manual state: "Record all radiation that is given, even if it is palliative."
EOD-Lymph Nodes--Colon: Are deposits of carcinoma in the pericolic fat still coded as lymph nodes when the pathology report states, "there is a high likelihood that these represent foci of venous invasion"? See Description.
Patient underwent resection for adenocarcinoma of the rectum. Path final diagnosis stated: "Regional lymph nodes: met carcinoma in 18 of
43 lymph nodes. Pathologic stage (AJCC/UICC 6th edition): pT3, V2, pN2, pMx. See comment." Path comment: "There are additional macroscopic stellate deposits of carcinoma in the pericolic soft tissue. According to the 6th edition of the AJCC staging manual, these should be designated as "V2," indicating that there is a high likelihood that these represent foci of venous invasion."
For cases diagnosed 1998-2003: Each grossly detectable nodule in the pericolonic fat is counted as one regional lymph node.
When the number of deposits is not mentioned, code Number of Regional Nodes Positive as 97 [Positive nodes but number of positive nodes not specified]. Unless the procedure is documented as a dissection, code Number of Regional Nodes Examined as 98 [Regional lymph nodes surgically removed but number of lymph nodes unknown/not stated and not documented as samping or dissection; nodes examined, but number unknown].
Surgery of Primary Site--Breast: How is this field coded when a patient has a reduction mammoplasty (for macromastia) and within the pathology specimen there is an incidental finding of carcinoma?
Code this reduction mammoplasty to the code which best fits the amount of tissue removed. Read the operative report carefully. Code as a partial mastectomy, skin- nipple- areola-sparing mastectomy, or total (simple) mastectomy. Use text fields to record the details.
Multiple Primaries (Pre-2007)/Histology (Pre-2007)--Breast: Would the simultaneously occurring histologies of "high grade ductal carcinoma in situ with micro invasion" and "keratinizing squamous cell carcinoma" be coded as two primaries or as a single primary when the pathologist is not clear whether two separate tumor masses exist?
For tumors diagnosed prior to 2007:
Code as two primaries, assuming the tumors are separate and the margins are clear/negative. Code 8071/3 [Invasive squamous cell ca, keratinizing] and 8500/3 [Ductal carcinoma, "microinvasive"].
For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.
Behavior Code/EOD-Extension--Bladder: How are these fields coded for a bladder tumor in which the pathologist states, "there is no definite invasion identified" but the urologist states the case as T1? See Description.
Patient presents with four bladder tumors, described as "each measuring close to 2 cm." A specimen was taken of only one of the tumors. The tops of the tumors were fulgurated, then vaporized methodically. No obvious tumor or residual was noted on re-inspection.
Pathology revealed papillary urothelial carcinoma, high grade, with no definite invasion identified. Small segments of muscularis propria were present. A comment read..."it is difficult to determine if lamina propria invasion is present due to marked necrosis and tissue fragmentation." Urologist staged this as AJCC cT2a, but based on the pathology findings changed it to cT1. The urologist insists this is invasive.
For cases diagnosed 1998-2003: Because of the damage to the specimen from cautery and the insistence of the urologist that the tumor was invasive, code extension for this case to 15 based on the physician's TNM category of T1.
A T1 is invasive--code the behavior /3. The urologist is confident it is invasive, and will likely treat the patient accordingly.
Surgery of Primary Site--Head & Neck: How is this field coded for a surgery titled "Parotidectomy with facial nerve dissection"? See Description.
If the operative report is not titled "total parotidectomy," can we assume that less than total parotidectomy was done? Can we assume that "facial nerve dissection" and "facial nerve monitoring" are other ways of stating "facial nerve spared"?
Use the best information available to determine whether or not all of the parotid has been removed. It is important to read the entire operative report and review the content of the pathology report. The Op report will usually include wording about how much was removed, and this can be confirmed by the path report. Do not make assumptions about the extent of the surgery based solely on the title used on the operative report.
For cases diagnosed 1998-2003: Code 30 [less than total parotidectomy] can be used when the parotid is not totally removed, but the exact type of partial parotidectomy cannot be determined. "Facial nerve monitoring" and "Facial nerve dissection" are synonymous with "facial nerve sparing."
Priorities/EOD-Lymph Nodes--Breast: Which part of the pathology report takes precedence when there is a discrepancy between the final path diagnosis and the CAP summary? See Description.
For example, breast primary: Final path states "14/18 nodes (+) for tumor & separate matted aggregate of axillary nodes (+) for tumor. Subpectoral lymph node (+) for mets ca. Path Gross states "18 separate lymph nodes identified...many (+) for tumor grossly. Aggregate of matted lymph nodes within axillary tissue (+) for tumor. Multiple separate lymph nodes submitted." CAP Micro Summary lists "20/16 nodes examined/positive." What is correct number of nodes positive & nodes examined in this case?
For cases diagnosed 1998-2003: The final pathology diagnosis has highest priority. The CAP summary is second priority. However, you always use the best information available. If the final path diagnosis is vague or unclear, information from the CAP summary can be used. In the case example, the total lymph node count from the final path diagnosis is unclear and the CAP summary provides clarification. Code the number of lymph nodes positive as 16 and the number examined 20. Subpectoral lymph nodes are regional nodes for breast primaries.
EOD-Size of Primary Tumor: Can size be coded from a needle bx that removes all of the invasive tumor and just leaves a "focus of in situ"? See Description.
For example: needle bx diagnosis is "tiny focus of tissue highly suspicious for tubular ca." The lumpectomy path states "single focus of low grade DCIS, no residual ductal ca." Can size be coded 001?
Code tumor size to 001 [Microscopic focus or foci only] for the invasive component. Code the tumor size 990 for cases diagnosed in 2004 and forward. Disregard the microscopic tumor found at further resection.
Other Therapy/Immunotherapy--Hematopoietic, NOS: How should erythropoietin be coded for leukemia or other hematopoietic diseases?
Do not code Erythropoietin as treatment, it is used as an ancillary drug for leukemias or other hematopoietic diseases. Record information about erythropoietin in the text field.
