EOD-Clinical Extension--Prostate: Must all three criteria be met (an elevated PSA; documentation that the physical exam was negative; and, if a TRUS was done, there is documentation that the findings were negative) in order to code this field to 15 [Tumor identified by needle by elevated PSA]?
For cases diagnosed 1998-2003:
Refer to the Prostate EOD Coding Guidelines, Final version distributed to SEER Registries 6/20/2001.
Prostate clinical EOD extension code 15 is used when all three criteria are met as listed on page 3 of the Prostate EOD Coding Guidelines. Meeting 1 or 2 of the 3 criteria is not sufficient for code 15. PE must be done and documented as negative. TRUS may or may not be done, but if done, must be documented as negative. PSA must either be elevated or there is no documentation about the PSA.
Codes 20 and 23-24 would be used with positive physical exam or positive TRUS.
Use codes 30-34 when there is no documentation that the physical exam was negative, or no documentation that the TRUS was negative, or when the prostatic apex is involved.
Primary Site--Breast: If a patient has multifocal tumors all in the upper outer quadrant of the breast, is the primary site coded to C-504 because all of the tumors are in UOQ or would the site be coded to C509 to reflect the fact that multiple tumors exist?
Code the primary site to C504 [Upper outer quadrant]. All disease is located in one quadrant, code that quadrant. When disease involves two or more quadrants and the point of origin cannot be determined, code C509 [Breast, NOS]. See 2004 SEER manual, page C-470 for instructions about invasive and in situ in different quadrants.
EOD-Clinical Extension--Prostate: How is this field coded when biopsies of the prostatic apex are positive and the physician clinically stages the case as T1c?
For cases diagnosed 1998-2003:
Code clinical extension to 33 [arising in the prostatic apex] when a biopsy of the prostatic apex is positive for malignancy, with no further evidence of involvement. If biopsies of both the apex and another site within the prostate (for example right lobe) are positive and there is no mention that the malignancy arose in the apex, code extension to 34 [extending into the prostatic apex].
First Course Treatment/Surgery of Primary Site--Lung: How is radiofrequency ablation for lung primaries coded?
Assign code 15 [Local tumor destruction, NOS] in the Surgery of Primary Site field. RFA is a technique where a probe placed in or near a tumor sends radio waves into the tumor, causing it to heat up and kill the cancer cells. RFA doesn't fit neatly into code 12 or 13, so we are left with the NOS code.
Primary site--Heme & Lymphoid Neoplasms: How is the primary site coded when a patient has a lymph node biopsy and peripheral blood that are positive for B-cell chronic lymphocytic leukemia/small lymphocytic lymphoma but refuses a bone marrow biopsy?
Code the primary site to C421 [bone marrow] per Rule PH5. Note 1 for Rule PH5 states CLL always has peripheral blood involvement. If the peripheral blood is positive for CLL/SLL and no bone marrow biopsy is done, code the primary site to C421 [bone marrow].

Reportability/Histology--Endometrium: Is endometrial hyperplasia with atypia equivalent to atypical hyperplasia of the endometrium (8380/2) and thus reportable?
Endometrial hyperplasia with atypia is equivalent to atypical hyperplasia of the endometrium (8380/2) and thus reportable for cases diagnosed 2021 and later. Our expert pathologist consultant confirmed this for us.
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.
Histology (Pre-2007): What code is used to represent the histology for a "malignant invasive gastrointestinal stromal tumor (GIST)"?
For tumors diagnosed 2001-2006: Malignant GIST is coded 8936/3.
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.
EOD-Extension--Corpus Uteri: How is this field coded for a stage III A endometrial primary with positive pelvic washings, involvement of the omental serosa, and negative lymph nodes?
For cases diagnosed 1998-2003: Code EOD-extension as 85 [Metastasis]. According to our TNM consultant, Omental metastasis is M1, Stage IVB [EOD 85].
