MP/H Rules/Histology/Multiple primaries--GE junction: How is histology coded for a goblet cell carcinoma in the GE junction? See discussion.
The patient was diagnosed with GE junction signet ring adenocarcinoma (8490/3) in 5/2012, treated with radiation. GE junction biopsy on 9/20/2012 showed residual signet ring carcinoma. Subsequent biopsies on 7/8/2013 showed GE junction biopsy of invasive adenocarcinoma, signet ring cell type along with “Esophagus, distal and GE junction biopsies” (site not further clarified in available documentation) with Goblet cell carcinoma. The histology code for the goblet cell carcinoma is needed to determine the number of primaries.
According to our expert pathologist consultant, goblet cell is a descriptive term and not a specific histology in this context. There is no ICD-O-3 code for it. The "goblet cell carcinoma" in this case is not a new primary.
Goblet cell is used to describe some cells containing mucin. In addition to individual tumor cells containing mucin which compresses the nucleus to give the appearance of signet rings, the mucin is present in columnar cells with the nuclei at one end -- this latter is a pattern often seen when glandular structures are formed by the tumor cells. It is also often intermixed with the signet ring cells in the surrounding stroma.
Surgery of Primary Site--Brain and CNS: What procedure code would be used for NeuroBlate Laser Interstitial Thermal Therapy? This procedure was used for a Glioblastoma of the brain.
If a pathologic specimen is not taken during this procedure, code in the surgery field using code 10 (Local tumor destruction, NOS). If specimen is sent to pathology, code 90, surgery, NOS. We will request this procedure be included in future treatment field coding documentation.
Our research notes that this procedure, also known as LITT (Laser Interstitial Thermal Therapy), is a surgical treatment. Lasers transmit heat to coagulate or destroy the brain tumors from the inside out.
Reportability--Head & Neck: Would this be reportable and if so what histology would be coded? Soft tissue mass left cheek excision reveals Carcinoma Ex Pleomorphic Adenoma Non-Invasive with focal vascular invasion. Margins clear.
Carcinoma ex pleomorphic adenoma (Ca-ex-PA) is reportable. Assign 8941/3. The WHO classification of head and neck tumors defines Ca-ex-PA as an epithelial malignancy arising in a benign pleomorphic adenoma. Most of these originate in the parotid gland but can also arise in other salivary glands.
Reportability--Lung: One of our facilities has a case they are not really sure how to report.
This patient came in for a double lung transplant due to COPD which occurred on 1/27/14. At time of transplant, the team found out the donor hospital had identified a small nodule in the right lower lobe donor lung, which they biopsied and deemed negative. However, the slides were reviewed and felt to represent adenocarcinoma. The team performed a right lower lobe lobectomy of the donor lung before transplanting into the patient.
So, we are not really sure how to handle this case. The adenocarcinoma actually belongs to the donor patient from another hospital, however, they actually didn’t identify it at that facility as their pathology was negative for a malignancy.
This very interesting case is not reportable to either facility. Since the right lower lobe nodule was resected prior to transplantation, the case does not belong to your patient. Ideally, the cancer should be assigned to the donor; however, donor information is confidential.
Reportability--Pancreas: Is this reportable? Is this benign? If reportable, what histology code and behavior code should be used? A final pathology diagnosis reads: "Cystic pancreatic endocrine neoplasm (CPEN)".
"Cystic pancreatic endocrine neoplasm (CPEN)" is reportable. Assign 8150/3 based on the information provided. We consulted our expert pathologist and he states "Since metastases have been reported in a few, and all the rest of the pancreatic endocrine tumors are now designated malignant, …we are safe considering them /3 until proven otherwise. Since most of them are non-functioning, [assign code] 8150/3 unless specified as to G1 (8240/3) or G2 (8249/3)."
MP/H Rules/Histology--Kidney, renal pelvis: How would you code this histology: Renal cell carcinoma, clear and eosinophilic cell type?
Kidney rule H5 applies, code the more specific histology which is clear cell renal cell carcinoma (8310/3). Per the WHO Tumors of the Urinary System, clear cell renal cell carcinoma contains both clear and eosinophilic cytoplasm. Eosinophilic is not a type or variant of renal cell carcinoma.
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.
MP/H/Histology--Kidney, renal pelvis: What is the histology code for renal cell carcinoma translocation type?
Code renal cell carcinoma translocation type as renal cell carcinoma, NOS, 8312. While WHO recognizes renal cell carcinomas with associated translocations, there is no specific ICD-O-3 code for this variant of renal cell carcinoma.
First course treatment: When a patient has a Haplo bone marrow transplant, is this coded as an allogenic bone marrow transplant since part of his marrow was used in addition to a donor?
Use code 12 in the Hematologic Transplant & Endocrine Procedures data field. Per the NCI, this procedure is an allogeneic transplant.
Rather than wiping out a patient’s immune system before transplanting donor bone marrow, doctors administer just enough chemotherapy to suppress the immune system, which keeps patients from rejecting the donated marrow without harming their organs. The procedure requires just a half-match, meaning that a patient’s parents or children could be suitable donors. AKA: Half-match transplants.
Summary Stage 2000--Melanoma: How should Summary Stage 2000 be coded for 2014+ diagnosed melanoma cases with satellite nodules or in transit metastases? See discussion.
The SEER SS (SSS) 2000 Manual indicates satellite nodules (NOS or less than/equal to 2cm from primary tumor) are regional by direct extension (code 2) and in-transit metastasis (satellite nodules greater than 2 cm from primary tumor) are coded as involvement of regional lymph nodes (code 3). However, CSv0205 indicates mapping for satellite nodules/in transit metastasis (coded in CS LN) was changed to Regional, NOS (code 5). There are no definitions listed for code 5 in the SSS 2000 Manual.
Our staff independently code SSS 2000. Should we code the existence of satellite nodules and in transit metastases according to the current definitions in the SSS 2000 Manual or using the mapping information from CSv0205?
Code the existence of satellite nodules and in transit metastases according to the current definitions in the SSS 2000 Manual. Do not use the mapping information from CS to code SSS.
