1) Assign /3 to mucosal carcinoid, unless stated to be in situ in the final diagnosis. ICD-O-3 is the reference for assigning the behavior code, not AJCC, EOD or CS.

2) The ICD-O-3 code for carcinoid of the sigmoid colon is C187 8240/3. This is reportable to SEER based on the final diagnosis above. Use the histology stated in the final diagnosis.

Code tumor size as 100 [10 cm]. Size from pathology or operative report is preferred over size from imaging.

Code SSF6 as 050 [Invasive and in situ components present, size of entire tumor coded in CS Tumor Size because size of invasive component not stated and proportions of in situ and invasive not known.]

There is invasive tumor present (as proven by the bone metastasis), but the size and proportion of the invasive component is unknown.

Please note: Extension must be coded at least to 10 [Confined to the breast tissue and fat including nipple and areola; Localized, NOS] in this case. Do not assign extension code 00 [in situ].

For tumors diagnosed prior to 2007:

Histology is coded 8140/3 [adenocarcinoma]. This is one reportable tumor of the left lung. According to our pathologist consultant, the tumorlets are collections of cells which appear to be of neuroendocrine origin, but are not malignant.

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.

There is no hierarchy among the various imaging studies. Assign CS extension based on the report documenting the greatest extension.

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.

Code what is known. In the example above, the tumor size and the extension are known and can be coded. The information is limited, but not completely missing.

Code what you DO know rather than coding nothing. Any metastases from the kidney would have been discovered during the workup of the rectal cancer.

See the General Coding Rules on page 92 of the 2004 SEER Manual for instructions about coding grade.

If the only information available is "Grade 2," assign code 2 [Grade II].

For tumors diagnosed prior to 2007:

Our pathologist consultant agrees with the consultant's diagnosis. Therefore, abstract this as one primary of the thyroid. Code the histology as 8344 [Papillary tall cell]. This is the most appropriate histology code available for this complex case.

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.

First, determine whether the bone mets in this case are progression of disease. If the patient was asymptomatic at the time of the mastectomy, the bone mets are disease progression, not initial stage.

If the initial stage includes the bone mets and they are not disease progression, extension must be coded to at least 10. Code site-Specific Factor 6 to 040 [Size of entire tumor coded, size of invasive component not stated].
