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
20000261 EOD-Extension--Lymphoma: What code is used to represent a non-Hodgkin lymphoma presenting with involvement of an extralymphatic organ and lymph nodes on the opposite side of the diaphragm? For cases diagnosed 1998-2003: Code the EOD-Extension field to 31 [30 + localized involvement of an extralymphatic organ or site; Stage III E]. 2000
20000511 EOD-Pathologic Review of Number of Regional Lymph Nodes Positive and Examined: What codes are used to represent these fields when only a regional lymph node (positive) aspiration is performed?

For cases diagnosed 1998-2003:

With the exception of those sites/histologies that require 99 in these fields, code the Number of Regional Lymph Nodes Positive field to 97 [Positive nodes but number of positive nodes not specified]. Code the Number of Regional Lymph nodes Examined field to 95 [No regional Lymph nodes removed, but aspiration of regional Lymph nodes was performed].

 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
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.

20000422 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. 2000
20000851 Primary Site: What site code is used to classify a femur biopsy with pathologic diagnosis of "Ewing sarcoma/primitive neuroectodermal tumor (PNET)"? See discussion. ICD-O-3 lists PNET as being site specific to C71._. The pathology report states "some authors consider both Ewing sarcoma and PNET to be the same histologic entity given that they share the same translocation between chromosomes 11 and 23." Code the Primary Site field to C40.2 [femur] based on Rule H in the ICD-O-3 that states, "Use the topography code provided when a topographic site is not listed in the diagnosis. This topography code should be disregarded if the tumor is known to arise at another site." 2000
20000461 Surgery of Primary Site/Date Therapy Initiated--Cervix: Should "negative endocervical curettings" be coded as surgical treatment for carcinoma in situ of the cervix primaries and should the date of the procedure ever be used in coding the Date Therapy Initiated field? For cases diagnosed 1/1/2003 and later: Code Surgery of Primary Site to 25 [D&C endocervical curettage (for in situ only)]. If this is the first treatment given, the Date Therapy Initiated is coded to the date of the curettage. 2000
20000513 Multiple Primaries/Histology (Pre-2007)--Bladder: What code is used to represent the histology and how many primaries should be coded for a TURB specimen that demonstrates carcinoma in situ, Grade I to II papillary transitional cell carcinoma, and high grade transitional cell carcinoma? See discussion.

Pathology report:

A. Biopsy, bladder neck, @ 6:00: Carcinoma in situ

B. Biopsy, Bladder wall, lateral, left:

1. Papillary carcinoma (Grade I-II)

2. Loose fragments of high-grade transitional carcinoma

C. Biopsy, Bladder neck @ 5:00: Carcinoma in situ

D. Biopsy, Bladder neck @ 7:00: Cystitis Glandularis

E. Biospsy, Bladder wall, posterior: Papillary carcinoma (Grade I)

For tumors diagnosed prior to 2007:

Code this case as one primary and code the Histology and Grade, Differentiation fields to 8130/34 [papillary transitional cell carcinoma, high grade].

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
20000552 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.
