CS Site Specific Factor 3--Prostate: When a prostatectomy specimen shows tumor focally penetrating through the capsule into periprostatic striated muscle tissue, is the involvement coded to 041 [periprostatic tissue] or 052 [skeletal muscle, NOS]?
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.
Assign code 052 [Levator muscle, Skeletal muscle, NOS, Ureter]. The description for this case states periprostatic "striated" muscle tissue. According to our pathologist consultant, "striated muscle in this context is skeletal muscle and the term is being used to differentiate the muscle from smooth (non-striated) muscle." Smooth muscle involvement would be most likely be coded 050 [Extension to bladder neck...] because smooth muscle in a prostatectomy or TURP specimen is usually from the urinary bladder neck.
Histology (Pre-2007)--Ovary: What codes are used to represent "mixed papillary serous and clear cell carcinoma" and "papillary serous carcinoma with focal clear cell features" of the ovary?
For tumors diagnosed prior to 2007:
Assign code 8323 [Mixed cell adenocarcinoma] to "mixed papillary serous and clear cell carcinoma." This is histology coding rule 3 in the 2004 SEER manual under single tumor (page 86). There is no other code for this mixture.
Example 1: 8323
Example 2: 8461 (clear cell is not coded according to Rule 6, page 87, because it is not the majority of the tumor).
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.
CS Lymph Nodes--Breast: Which category has priority when both apply, "Regional lymph nodes, NOS" or "Stated as N_, NOS"? See Discussion.
Example: When there is a clinical diagnosis of axillary lymph node metastasis for a breast primary on a physical exam "Enlarged axillary lymph nodes suspicious for metastatic involvement", as well as a clinical N1 designation, do we code as 60 [Axillary LNS, NOS] or 26 [Stated as N1, NOS]?
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.For the example provided, assign code 25 [Movable axillary lymph node(s)...] for "Enlarged axillary lymph nodes suspicious for metastatic involvement." Code 60 [Axillary/regional lymph node(s), NOS] is the least specific and would not be used in this case because axillary nodes are defined in code 25. Code 26 is for cases in which "N1, NOS" documented by the physician is the only information available.
Primary Site--Bladder: What subsite is used for fundus of the bladder?
As of November 2005, Code fundus of bladder to C678 [overlapping lesion of bladder]. Opinions vary regarding the definition of bladder "fundus." However, according to our pathologist consultant, fundus includes posterior, anterior and lateral walls and dome. Fundus does not include the trigone.
A correction to page C-595 of the 2004 SEER manual will be included in the next errata.
CS Site Specific Factor--Lymphoma: Can the International Prognostic Index (IPI) score be taken from a TNM form in the record? If so, what score would we code for "low" (0-1 points) and "high" (4-5 points)?
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 IPI score from the TNM form can be used to code SSF 3. Without further information, code "low" as 000 [0 points]. Code "high" as 004 [4 points].
Reportability/Behavior--Brain and CNS: How is a brain "neoplasm" diagnosed only by CT scan reported to SEER? See Discussion.
We have a significant number of patients who come into our emergency room and are diagnosed with a brain neoplasm by CT scan. They are transferred to another facility for further care. Some of those facilities will give us information - histology, treatment, etc. Some will not. How are we supposed to report these brain neoplasms if we don't know if they are benign or malignant? Can we report them as behavior code 9 or do we just report them as benign if we can't get any further information?
The case above is reportable and 8000/1 is the most appropriate histology/behavior code. A clinical diagnosis alone from diagnostic imaging reporting a brain 'neoplasm' (with a diagnosis date supporting the reportable case requirements) even with no other information available (from biopsy or resection) is reportable. Care should be taken when reviewing terms used by the radiologist on these reports, since some tumors exhibit defining characteristics that can be picked up on diagnostic imaging.
CS Lymph Nodes--Breast: Is it better to code to 26 [Stated as N1, NOS] or 28 [Stated as N2, NOS] instead of 60 [Axillary/regional lymph nodes, NOS; Lymph nodes, NOS] when the only information in the medical record is the TNM N1 or N2 physician stage?
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. When the only indication of lymph node involvement is the physician's N category from TNM, code the numerically lowest equivalent CS Lymph Nodes code for that N category.
In the breast schema, CS Lymph Nodes code 26 corresponds to N1, NOS and code 28 corresponds to N2, NOS.
Histology (Pre-2007)--Sarcoma: How is "acral myxoinflammatory fibroblastic sarcoma" coded?
For tumors diagnosed prior to 2007:
The ICD-O-3 histology code is 8811/3 [Fibromyxosarcoma] according to the WHO Classification of Tumours of Soft Tissue and Bone. WHO defines myxoinflammatory fibroblastic sarcoma (MIFS) as "a unique low grade sarcoma with myxoid stroma, inflammatory infiltrate and virocyte-like cells that predominantly involves the hands and feet."
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.
CS Lymph Nodes/Reg LN Pos/Exam: Is a final pathologic diagnosis of "Level 8 lymph node: Fibroadipose tissue containing a minute lymphoid aggregate, negative for malignancy" a lymph node for the purpose of coding these fields?
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. "Fibroadipose tissue containing minute lymphoid aggregate" qualifies as a lymph node. Include in count as one lymph node examined in the example above assuming this is regional to the primary site.
CS Lymph Nodes: Are lymphatic channels/vessels within an organ coded as regional lymph nodes?
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.Lymphatic channels/vessels carry lymph fluid throughout the organs and tissues of the body. Lymph channels/vessels within an organ are not nodes. Lymph channels/vessels outside an organ are not nodes.
