Report Question ID Question Discussion Answer Year
20000848 Primary Site--Lymphoma: How should you code the primary site for a lymphoma that presents in a "mediastinal mass"? Code the Primary Site field to C77.1 [mediastinal lymph nodes]. 2000
20000846

EOD-Extension/EOD-Lymph Nodes--Bladder: Are "perivesical nodules" coded in the EOD-Lymph Nodes field or are they discontinuous extension and coded in the EOD-Extension field?

For cases diagnosed 1998-2003:

Code "perivesical nodules" in the EOD-Lymph Nodes field as involvement of regional lymph nodes. Each gross nodule of metastatic carcinoma in the fat surrounding an organ is counted as one positive regional lymph node.

 2000
20000845 Primary Site: What code should be used to represent the site for an "extraovarian" papillary serous adenocarcinoma located in the "rectal muscle sheath"? See discussion. The location of the tumor in the rectus muscle sheath is unusual and suggests an origin within a preexisting mullerian. Code the Primary Site field to C49.4 [connective, subcutaneous and other soft tissues of the abdomen]. 2000
20000844 EOD-Pathologic Review of Number of Regional Lymph Nodes Positive and Examined--Colon: What codes are used to represent these fields when the pathology from a colon cancer resection describes 2/16 positive pericolonic lymph nodes and a "metastatic nodule in the pericolonic fat"?

For cases diagnosed 1998-2003:

Code the Number of Regional Lymph Nodes Positive field to 03 and the Number of Regional Lymph Nodes Examined field to 17. Each grossly detectable nodule in the pericolonic fat is counted as one regional lymph node.

 2000
20000843 Place of Birth: When there is conflicting information, which record takes precedence in coding this field, the medical record or the death certificate? If there is a discrepancy, use the information from the medical record to code the Place of Birth field. The information from the medical record is provided by the patient, the information on the death certificate is provided by others. If the medical record does not contain birth information, use the information from the death certificate. 2000
20000842

Surgery of Primary Site--Skin: Explain the difference between code 30 and code 45.

Code 30 [Biopsy of primary tumor followed by a gross excision of the lesion]

Code 45 [Wide excision or re-excision of lesion or minor (local) amputation with margins more than 1 cm, NOS. Margins MUST be microscopically negative.]

 For cases diagnosed 1/1/2003 and after: Code 30 represents a biopsy or excision in which the margins of excision are less than 1 cm or the margins are unknown. Code 45 represents a wide excision in which it is known that the margins of excision are greater than 1 cm. 2000
20000839

Multiple Primaries (Pre-2007)--Thyroid: Does the rule in the 3rd Edition of the SEER Program Code Manual apply to cases diagnosed before 1998 that states if there are two separate carcinomas in the thyroid, one papillary and the other follicular, it is one primary and coded to the combination code 8340/3 [Papillary and follicular carcinoma]? See discussion.

If the rule applies to cases diagnosed before 1998, does SEER plan to ask that cases diagnosed prior to 1998 be recoded?

The rule applies to tumors diagnosed 1998-2006. The rule is not retroactive. At this time, SEER does not plan to ask that tumors diagnosed prior to 1998 be recoded.

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.

 2000
20000561 EOD-Pathologic Extension--Prostate: Can a pathological extension code be assigned when a retropubic prostatectomy is done? See discussion. The TNM manual states, "Total prostatoseminalvesiculectomy and pelvic lymph node dissection are required for pathologic staging."

For cases diagnosed 1998-2003:

The pathology report from a retropubic prostatectomy should be used to code the Pathologic Extension field. This field is coded using pathology report information from the prostatectomy operation regardless of the surgical approach and regardless of whether or not a pelvic lymph node dissection was performed. This is one area in which TNM rules for pathologic staging and SEER rules for EOD are slightly different.

 2000
20000556 Surgery of Primary Site--Cervix: How is this field coded for a cervix primary when a biopsy removes the entire tumor? See discussion. Path from biopsy shows "severe dysplasia--CIN III" and the report from an endocervical curettage (ECC) is "chronic cervicitis"? For cases diagnosed 1998 and later: Code the Surgery of Primary Site field to 25 [Dilatation and curettage; endocervical curettage (for in situ only)]. 2000
20000555 EOD-Extension--Ovary: What code is used to represent this field for an ovarian primary presenting with "spread to the omentum"?

For cases diagnosed 1998-2003:

Code the EOD-Extension field to 75 [Peritoneal implants, NOS] because the size of the implants on the omentum is not known.

Note 6 was added to the EOD scheme which states that both direct extension and discontinuous metastasis to the omentum are coded in the range 70-75 depending on how the peritoneal implants are described.
