|---|---|---|---|---|
| 20000450 | Primary Site--Esophagus: What is the difference between C15.5 [Lower third of esophagus] and C15.2 [Abdominal esophagus]? | These descriptions represent the use of two different ways the esophagus can be divided anatomically. The two different systems used are illustrated in the SEER Self Instruction Manual for Tumor Registrars: Book 4. Assign the primary site code that describes the location of the tumor in the same way the tumor's location is described in the medical record. | ||
| 20000449 | EOD-Extension/EOD-Lymph Nodes--Lung: Is "subcarinal extension" with no mention of lymph nodes coded in the EOD extension field or in the EOD lymph node involvement field? See discussion. | Should "subcarinal extension" with no mention of lymph nodes be assumed to be direct contiguous extension of the primary tumor or does it represent lymph node involvement? If it is direct extension, should we code it as 70 in the extension field? If not, should we code it as 2 in the lymph node involvement field? |
For cases diagnosed 1998-2003:
Code the EOD-Extension field to 70 [mediastinum, direct extension]. |
|
| 20000447 | Extension/Ambiguous terminology: How should the terms "entrapped by tumor" and "encased by tumor" be interpreted when coding these fields? | Each case must be reviewed in its entirety to determine the appropriate coding of these fields. However, in general the terms "entrapped" and "encased" should NOT be interpreted as involvement unless there is other clinical or pathologic evidence to support involvement. | ||
| 20000440 | Grade, Differentiation--Brain and CNS: Can grade IV be implied for brain primaries with the histology of glioblastoma multiforme, even if there is no statement of grade in the path report? See discussion. | Dr. Platz has instructed the Iowa registry to code glioblastoma multiforme to grade IV, even when there is no corroborating statement of grade in the path report. This is also supported in some references. | Code the Grade, Differentiation field to 9 [Cell type not determined, not stated or not applicable] in the absence of a stated grade on the pathology report. If a grade is stated, code the stated grade. SEER does not recommend adopting the rule in the Discussion. | |
| 20000438 | EOD-Extension/SEER Summary Stage 2000--Kidney/Eye: What codes are used to represent these fields for simultaneous bilateral Wilms tumor or simultaneous bilateral retinoblastoma? | For cases diagnosed 1998-2003:
Code the EOD-Extension field to 85 [Metastasis] and the SEER Summary Stage 2000 field to 7 [Distant] for both types of tumor. Each kidney and each eye are staged separately in the AJCC, 6th ed., but for SEER we would abstract these diagnoses as one case and code the EOD and stage fields to distant to reflect the involvement of both eyes or both kidneys. |
||
| 20000437 | EOD-Extension--Lymphoma: Should "bilateral" inguinal lymph node involvement by lymphoma be two chains for the purpose of coding EOD? |
Yes. Bilateral inguinal lymph nodes are coded as two chains/regions. |
||
| 20000436 | 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. |
|
| 20000433 | Diagnostic Confirmation: Is it appropriate to code this field to "radiography" confirmation when a CT scan does not actually contain a diagnosis of malignancy, however, the discharge diagnosis in the medical record of "probable malignancy" is likely based on the abnormal CT findings? See discussion. | 10/1/02 CT of Chest: 1) Huge (left) suprahilar mass. 2) Moderate volume loss, left lung. Appearance suspicious of LLL collapse. An infiltrate is seen in the aerated upper lobe as well as pleural effusion. 3) Streaky and nodular changes are noted at the right base that may represent possible lymphangetic spread of tumor.
10/23/02 Discharge Dx: Lung mass, probably carcinoma. |
Code the Diagnostic Confirmation field to 7 [Radiography]. This is appropriate because it was the scan evidence that was used to make the clinical diagnosis. | |
| 20000431 | Surgery Fields--Multiple sites: What code is used to represent these fields for the following surgical procedures?
1. Tongue, NOS - Hemiglossectomy with lymph node dissection 2. Choroid - Eye enucleation 3. Vulva, NOS - Vulvectomy with bilateral lymph node dissection 4. Gallbladder - Cholecystectomy 5. Lung - Laminectomy with partial removal of tumor |
For cases diagnosed 1/1/03 and later: 1. Code Surgery of Primary Site to 30 and Scope of Regional Lymph Node Surgery to 3. 2. Code Surgery of Primary Site to 41. 3. Code Surgery of Primary Site to 40 and Scope of Regional Lymph Node Surgery to 3. 4. Code Surgery of Primary Site to 40. 5. Code Surgical Procedure of Other Site to 4. |
||
| 20000430 | Histology (Pre-2007)--Colon: What code is used to represent histology when the surgeon describes a sessile polyp and the final path diagnosis is stated as: "Rectal sessile polyp: Invasive moderately differentiated adenocarcinoma" (pathologist does not state that it is "arising in a sessile polyp")? | For tumors diagnosed prior to 2007:
Code the Histology field to 8210/3 [adenocarcinoma arising in a polyp]. The structure in which this adenocarcinoma is arising, is a polyp.
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. |
