Radiation Therapy: Would tomotherapy, described as targeted IMRT, be coded as external beam?
Code tomotherapy as 1 [Beam radiation].
Tomotherapy is external beam radiation therapy. It is a type of IMRT. Intensity-modulated radiation therapy (IMRT) is an advanced mode of high-precision radiotherapy that utilizes computer-controlled x-ray accelerators to deliver radiation. Tomotherapy is a CT image guided IMRT.
Multiple Primaries--Lymphoma: How many primaries should be abstracted if DLBCL (9680/3) and Mantle Cell Lymphoma (9673/3) occur at the same time in different lymph nodes? How would Sequence be coded if the case is multiple primaries?
For cases diagnosed prior to 1/1/2010:It is important to note for this case that the two different types of NHL occurred in different lymph nodes; one type in one lymph node and the other type in another lymph node.
Use the fold-out table to determine single vs multiple primaries. According to the table, 9673/3 and 9680/3 would be two primaries no matter which of these was "first."
Assign the lower sequence number to the primary with the worse prognosis when two primaries are diagnosed simultaneously. Base the prognosis decision on the primary site, histology, and extent of disease for each of the primaries. If there is no difference in prognosis, the sequence numbers may be assigned in any order.
For cases diagnosed 1/1/10 and later, refer to the Hematopoietic and Lymphoid Neoplasm Case Reportability and Coding Manual and the Hematopoietic Database (Hematopoietic DB) provided by SEER on its website to research your question. If those resources do not adequately address your issue, submit a new question to SINQ.
MP/H Rules/Histology: How is histology coded for a partial vulvectomy showing "vulvar intraepithelial neoplasia III, basaloid type"? See Discussion.
Is this VIN III (8077/2) or basaloid squamous cell carcinoma (8083 and change the behavior code from 3 to 2)? It seems that H4 and H6 both lead to 8083.
For cases diagnosed 2007 or later, assign 8077/2 [Squamous intraepithelial neoplasia, grade III] for VIN III diagnoses, regardless of the type. According to the WHO Classification of Tumours (page 319), "VIN is predominately of the warty or basaloid types...."
Use the multiple tumors module to determine the histology code for VIN. Rule H21 applies.
MP/H Rules/Histology--Ovary: How is histology coded for "serous carcinoma, papillary invasive pattern"?
For cases diagnosed 2007 or later, code the histology 8441/3 [Serous carcinoma, NOS]. Use the Other Sites rules. Start with rule H8 and stop at rule H11. "Pattern" is not one of the terms used to identify a specific type (See H16), so papillary is ignored.
Date of Multiple Tumors--Breast: How is this field coded when a second breast tumor is found at mastectomy two months after the original breast cancer was diagnosed, but during initial workup and treatment? See Discussion.
Breast cancer was diagnosed on core biopsy on 02-27-07. It was not known that the breast was harboring 2 tumors until mastectomy was done on 4-01-07. Both tumors are counted as one primary.
Code "Date of Multiple Tumors" field to the date of the mastectomy. That is the date that multiple tumors were discovered.
CS Site Specific Factor--Head & Neck: How is Site Specific Factor 2 coded when the pathologist describes regional lymph nodes as "matted"? See Discussion.
The primary tumor is located in the tonsil. The patient underwent neck dissection. Pathology report stated there were matted regional lymph nodes. Does the term matted describe extracapsular extension? The definition for site specific factor 2 uses the term "fixed" to describe extracapsular extension (but not matted). For breast, fixed/matted appear to be interchangeable. Would they also be interchangeable for head and neck cases?
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."Matted" is not a synonym for "Fixed" in the CS schema for Head and Neck. "Matted" is not indicative of extracapsular extension for the Head and Neck schema.
MP/H Rules/Histology--Thyroid: How is histology coded for a thyroid tumor described as "predominantly papillary carcinoma, tall cell variant, follicular type"?
For cases diagnosed 2007 or later, assign code 8340 [Papillary carcinoma, follicular variant] according to rule H15 for Other Sites.
"Predominantly" and "type" indicate specific histologies. "Variant" does not. See rule H13. The histology in this case is papillary and follicular. Tall cell variant is ignored.
MP/H Rules/Histology--Peritoneal primary: Can the cell types from the primary site and a metastatic site be combined to code histology? See Discussion.
Patient has vaginal mass biopsy diagnosed as 'papillary carcinoma with psammoma bodies.' Two weeks later the patient has laparoscopy with multiple peritoneal biopsies, diagnosed as 'well differentiated serous adenocarcinoma'. Patient stated to have peritoneal primary with mets to vagina and was treated with chemotherapy. Do we code the histology to 8441/31 from the primary site biopsies, or can we use 8460/3, combining the cell types from the primary and metastatic sites? Please see SINQ 20041062 for a similar question before the 2007 MP/H rules.
For cases diagnosed 2007 or later, assign code 8441 [serous adenocarcinoma, NOS].
Code the histology from the primary site when available. Do not combine histologies from primary and metastatic sites.
In this primary peritoneal case, the diagnosis from the peritoneal biopsies was serous adenocarcinoma.
CS Lymph Nodes--Ovary: Are positive lymph nodes removed from "colon tissue" during a modified posterior pelvic debulking regional or distant? If regional, what is the appropriate CS LN code?
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.Pericolonic lymph nodes are "regional" lymph nodes for an ovarian primary. If you do not have enough information to assign codes 12-30, assign code 50 [Regional lymph nodes, NOS].
MP/H Rules/Multiple primaries--Breast: Would a left chest wall mass excision stated to be ductal carcinoma consistent with a breast primary and, "compatible with either local recurrence or potentially a metastasis" be a new primary per the MP/H rules? See Discussion.
Patient underwent mastectomy in 1986 for infiltrating ductal carcinoma of left breast. Excision of left chest wall mass in March 2009 showed ductal carcinoma consistent with breast primary. The pathology report COMMENT stated it would be compatible with either local recurrence or a metastasis. The patient's primary breast carcinoma material is not available for direct comparison and the MP/H rules instruct us to ignore metastasis.
For cases diagnosed 2007 or later, the MP/H rules do not apply to metastasis. If there is no further information available for this case, the MP/H rules do not apply to the 2009 diagnosis.
