Histology (Pre-2007)--Colon: What code is used to represent the histology "adenocarcinoma arising in a papillary adenomatous polyp"? See discussion.
Is "adenocarcinoma arising in a papillary adenomatous polyp" equivalent to adenocarcinoma in a villous adenoma [8261/3] or adenocarcinoma in an adenomatous polyp [8210/3]?
For tumors diagnosed prior to 2007:
Code the Histology field to 8261/3 [adenocarcinoma in a villous adenoma]. In describing colon polyps, papillary and villous are equivalent terms.
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.
Primary Site--Lymphoma: How should you code the primary site for a lymphoma that presents with involvement of an extranodal site and regional lymph nodes? See discussion.
1. Lymphoma involves the spleen and the splenic lymph nodes.
2. MALT Lymphoma involves the stomach and the gastric and iliac lymph nodes.
1. Code the Primary Site field to C42.2 [spleen].
2. Code the Primary Site field to C16._ [stomach].
When lymphoma presents in an extranodal site and in the regional lymph nodes for that extranodal site, code the Primary Site field to the extranodal site. The typical disease process is that lymphoma can spread from an extranodal organ to its regional lymph nodes. It cannot metastasize from the regional lymph node to the extranodal organ. The exception to this would be if the lymph nodes presented as one large mass that extended into the regional organ.
EOD-Size of Primary Tumor--Lung: Can tumor size of 002 [Malignant cells present in bronchopulmonary secretions] be used when there is a lung mass seen but the diagnosis is from a positive bronchopulmonary secretion?
For cases diagnosed 1998-2003:
EOD-Size of Primary Tumor code 002 [Malignant cells present in bronchopulmonary secretions] is used only when there is no visible primary lung tumor and bronchopulmonary secretions are positive for lung malignancy.
Even if the diagnosis was made by cytology of broncho-pulmonary secretions, if there is a visible mass, code the size of the mass if known, code 999 if size is unknown.
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.
Surgery of Primary Site--Ovary: What code is used to represent this field when a patient has a history of a previous organ removal and has additional surgery/organ removal for a present cancer (e.g., History of a 1984 hysterectomy and in 2003 has ovarian primary treated with BSO)?
For cases diagnosed 1/1/2003 and after: Code the Surgery of Primary Site field to 52 [Bilateral salpingo-oophorectomy WITH hysterectomy].
Surgery of Primary Site/Reconstruction-First Course--Breast: If the plan is to "reconstruct" the breast 6 months after an ipsilateral modified radical mastectomy, is the time span a problem or should it be coded in the Surgery of Primary Site field because it was planned?
For cases diagnosed 1/1/2003 and after: Code the Surgery of Primary Site field to 55 [Modified radical mastectomy WITHOUT removal of uninvolved contralateral breast, Implant]. The time span is not a problem as long as the reconstruction was planned as first course, which is indicated by tissue expander insertion at the time of the original surgery.
EOD-Clinical Extension--Prostate: How do you distinguish between clinical extension codes of 10, 13, 14, and 20 for cases with a benign prostate per digital rectal exam that appear localized after TURP/prostatectomy? Can the clinical extension code of 10 be used if the term "microscopic carcinoma" is noted in the pathology report without also mentioning "foci" or "Stage A" for clinically inapparent tumors?
For cases diagnosed 1998-2003:
When the prostate feels benign and the cancer is found incidentally at the time of the microscopic exam, code the EOD-Extension field to 10 [number of foci or % of involved tissue not specified]. Code as 13 (less than or equal to 5%) or 14 (greater than 5%) if percentage involved is given in the tissue resected. If the path report states "solitary focus of carcinoma" without mentioning the total amount of tissue resected, code extension to 13. If there is more than one focus, code extension to 10. Don't assign a code of 20 unless the tumor is clinically apparent.
Surgery of Primary Site: Should laparoscopy be coded as exploratory surgery? See discussion.
Many surgeons are doing exploratory surgery with laparoscopy involving a very small incision, but they can examine organs and take biopsies. Should laparoscopy be coded as exploratory surgery?
For cases diagnosed 1/1/1998 and later: Exploratory surgical procedures, such as laparoscopic surgeries, are not coded in the Surgery of Primary Site field.
EOD-Extension--Lung: If LUL mass "crosses the pleural surface" into the LLL, do we assume this represents extension to the pleura? See discussion.
9/22/93 Left upper lobe lobectomy: 3 x 3 cm mass in the periphery of the LUL near the LLL. Multiple enlarged nodes around the aortic arch and within the pulmonary fissure.
9/22/93 Pathology: Moderately differentiated Adenoca. The neoplasm does cross the pleural surface into the segment of the lower lobe. Lower margin of resection is free of neoplasm. Six lymph nodes negative for metastatic carcinoma. Tumor staged as T2N0M0 Stage Ib by physician.
Is tumor extension coded 10 [confined to one lung] or 40 [extension to pleura]?
For cases diagnosed 1998-2003:
Code the EOD-Extension field to 40 [extension to pleura]. The tumor has penetrated (extended to) the pleura.
EOD-Size of Primary Tumor--Breast: If the patient has inflammatory carcinoma of the breast, is the tumor size coded as 998 even though we have a tumor size?
For cases diagnosed 1998-2003:
Code the EOD-Size of Primary tumor field to 998 [Diffuse; widespread; 3/4 or more of breast; inflammatory carcinoma] for all inflammatory breast carcinomas.
These cases have a worse prognosis because of the dermal lymphatic invasion. Half of the inflammatory breast carcinomas will have no palpable mass.
