CS Extension/CS Lymph Nodes--Lung: How are these fields coded if a lobectomy path specimen indicates that two intrapulmonary lymph nodes are involved by direct extension from the primary tumor?
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 regional lymph node involvement in CS lymph nodes even when the lymph nodes are involved by direct extension. Do not code direct extension to lymph nodes in CS extension.
Ambiguous Terminology/Date of Conclusive Terminology: If there is an unknown date of diagnosis, should the Ambiguous Terminology field always be coded to 9 and the Date of Conclusive Terminology be coded to 99999999? See Discussion.
Scenario: Mammogram is suspicious for carcinoma, unknown date in 2007. A biopsy prior to admission to reporting facility is positive for carcinoma. Patient seen at reporting facility in June 2007 for treatment.
The purpose of the data item "Ambiguous Terminology" is to flag cases entered into the registry based on a diagnosis with ambiguous terminology. Because the case above was entered into the registry based on conclusive terminology, code Ambiguous Terminology to 0 [Conclusive term] and code Date of Conclusive Terminology to 88888888 [not applicable].
CS Site Specific Factor--Lymphoma: Can the registrar calculate the International Prognostic Index (IPI) score from information found in the H&P or on the back of a TNM form for the SSF 3 field if the physician does not document it in the medical record?
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.Record the IPI score in SSF3 when the score is documented in the medical record. If the score is not stated, do not calculate it.
Reportability--Brain and CNS: In addition to Schwannoma, are there additional types of benign tumors that arise in peripheral nerves along the spinal cord that are not reportable? See Discussion.
Are neuroepitheliomatous neoplasms such as ganglioneuroma, gangliocytoma, ganglioglioma occurring along the spinal cord reportable? Are nerve sheath tumors such as neuroma occurring along the spinal cord reportable? Angioma?
Reference: SINQ 20051071; Primary Central Nervous System Tumors, NPCR Training Materials 2004
Reportability depends on the location of the tumor. Tumors in the following sites are reportable:
C700 - C709
C710 - C719
C720 - C729
C751 - C753
Benign and borderline tumors of the peripheral nerves (C47_), including peripheral nerves along the spinal cord, are not reportable.
Please note: spinal schwannomas arising in the nerve root or spinal dura are reportable.
MP/H Rules/Histology--Prostate: If a patient is stated to have prostate "cancer" but a pathology report is not available nor is a specific histology stated in the medical record, can this histology be coded to 8140 [adenocarcinoma] instead of 8000/3 [cancer] because the vast majority of prostate cancers are adenocarcinomas?
For cases diagnosed 2007 and later, the correct histology code is 8000/3 [cancer]. The steps used to arrive at this decision are:
Open the Multiple Primary and Histology Coding Rules Manual. Choose one of the three formats (i.e., flowchart, matrix or text). Go to the Other Sites Histology rules because no specific rules have been developed for prostate primaries.
To determine the histology, start at the SINGLE TUMOR: INVASIVE ONLY module, rule H8. The rules are intended to be reviewed in consecutive order within a module. Code the histology documented by the physician when there is no pathology/cytology specimen or the pathology/cytology report is not available. Code the histology as 8000/3 [cancer] because that is the only available information. In the absence of a pathology report or any other histologic confirmation, code the histology based on the information available.
Histology--Lymphoma: How is a "lymphocytic lymphoma of follicular center cell origin" coded?
For cases diagnosed prior to 1/1/2010:Assign code 9690 [Follicular lymphoma, NOS]. According to the WHO Classification of Lymphoid tumors, follicular lymphoma is a neoplasm of follicle center B cells which has at least a partially follicular pattern.
Assign code 9695 for follicular lymphoma grade 1, 9691 for follicular lymphoma grade 2, and 9698 for follicular lymphoma grade 3.
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.
Surgery of Primary Site--Breast: Should code 51 (Modified radical mastectomy without removal of uninvolved contralateral breast) be used when a patient has excisional biopsy (22) and axillary dissection followed by a simple mastectomy without removal of uninvolved contralateral breast (41) as part of the first course of treatment?
Assign code 51 or 52 if a patient has an excisional biopsy and axillary dissection followed by a simple mastectomy during the first course of therapy. Code the cumulative result of the surgeries, which is a modified radical mastectomy in this case.
SEER collects only one surgery code per case. Code the most invasive, extensive or definitive surgery in Surgery of Primary Site.
Grade, Differentiation: How is grade coded for cases using the FNCLCC (Federation Nationale des Centres de Lutte Contre Ie Cancer) system? See Discussion.
Is FNCLCC a recognized system in the United States? Tongue was the primary site for the case we saw that used FNCLCC.
Do not code the data item Grade based on the FNCLCC grade. You may record the FNCLCC grade in a text field.
Reportability/Primary Site--Brain and CNS: Is a chondroma, NOS or a chondroblastoma, NOS that occurs in an intracranial site or along the spinal cord reportable? See Discussion.
In ICD-O-3, chondroma and chondroblastoma are site-associated morphologies for bone. If a chondroma or a chondroblastoma occurs along the spinal cord, is this one of those situations where we can be quite comfortable with a default site to bone and not to spinal cord?
Reference: ICD-O-3; Primary Central Nervous System Tumors, NPCR Training Materials 2004; SINQ 20021152
Chondroma, NOS or chondroblastoma, NOS occuring in intracranial sites or along the spinal cord are not reportable.
Chondroma, NOS and chonroblastoma, NOS are benign tumors of the bone itself, not the intracranial contents.
Type of Multiple Tumors--Colon: How is this field coded for a case in which the patient is found to have two in situ polyps and an adenocarcinoma arising in a polyp all in the same segment of the colon? See Discussion.
Code 30 would not count the fact that these are polyps. Code 31 states "AND a frank adenocarcinoma." What would be the correct code?
Assign code 30 [In situ and invasive] in this case. Code 31 does not apply here because frank adenocarcinoma is not present.
