EOD-Size of Primary Tumor--Prostate: If you only have a biopsy and not a resection of the primary site, can you code the size of the prostate nodule demonstrated on digital rectal exam? See discussion.
Example 1: Digital rectal exam reveals 1 cm left side prostate nodule. TRUS-guided biopsy of left side of prostate shows adenocarcinoma. Right side biopsy is negative. Is size coded to 010 or 999?
Example 2: Digital rectal exam reveals 1 cm left side prostate nodule. Bone scan was positive for metastatic disease. Is size coded to 010 or 999?
For cases diagnosed 1998-2003:
You need path confirmation that a malignancy exists in the prostate before you can code the size of the nodule seen clinically.
Example 1: Code the EOD-Size of Primary Tumor to 010 [1 cm], because the nodule in the prostate is confirmed as cancer by needle biopsy.
Example 2: Code the EOD-Size of Primary Tumor to 999 because there was no pathologic confirmation of malignancy.
Surgery of Primary Site--Breast: What code is used to represent this field for a breast primary treated with a "bilateral mastectomy"? See discussion.
Pt diagnosed with rt breast primary opted to be treated with rt modified radical mastectomy and lt simple mastectomy. Path revealed invasive ductal carcinoma on the rt and ductal carcinoma in situ on the lt. Path reported 14 axillary lymph nodes were found in the mastectomy specimen.
There are two primaries. For cases diagnosed 1/1/2003 and after: For the rt breast, code Surgery of Primary Site to 51. The contralateral left breast malignancy is not involved with the right breast primary by either direct extension or metastasis. Codes 42 and 52 are used to capture prophylactic mastectomy of the opposite noncancerous breast. In this case, the opposite breast has cancer so these codes cannot be used. Code Scope of Regional Lymph Node Surgery to 5 and Surgical Procedure of Other Site to 0.
For the lt breast, code Surgery of Primary Site to 41, Scope of Reg LN Surgery to 0, and Surgical Procedure of Other Site to 0.
Surgical Procedure of Other Site: Is the excision of a distant lymph node or a fine needle aspirate (FNA) of a distant lymph node coded as a Surgical Procedure of Other Site, even though they are performed for diagnostic purposes and not intended as treatment?
For cases diagnosed 1/1/2003 and after: Code the Surgical Procedure of Other Site field to 3 [Non-primary surgical procedure to distant lymph nodes] for an excision of a distant lymph node because it is a surgical procedure. However, if only a fine needle aspirate of a distant lymph node is done, code this field to 0 [None].
Fine needle aspirates of regional lymph nodes are the only FNA biopsies to be coded in a surgery field (Scope of Regional Lymph Node Surgery field). In addition, FNA biopsies of regional nodes are also included in the EOD-Number of Positive Regional and Examined Lymph Nodes fields.
EOD-Extension/EOD-Lymph Nodes--Kaposi Sarcoma: What code is used to represent this field for a Kaposi sarcoma with no skin lesions but positive lymph node and bone marrow biopsies?
Code the EOD-Extension field to 13 [Visceral (e.g., pulmonary, gastrointestinal tract, spleen, other)], because of the positive bone marrow. Code the EOD-Lymph Nodes field to 3 [Both clinically enlarged palpable lymph nodes (adenopathy) and pathologically positive lymph nodes], for the pathologically positive node.
Note: Potential revision of the extension scheme will be referred to SEER Medical Advisory Group (SMAG).
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."
EOD-Pathologic Extension--Prostate: If there is residual tumor in the distal urethra on prostatectomy, does that mean there is distal urethral margin involvement? See discussion.
2/98 Prostate bx: Right apex, right mid and right base positive for adenocarcinoma.
6/1/98 Radical retropubic prostatectomy w/ bilateral pelvic lymph node dissection. Pathology: Residual adenocarcinoma in distal urethra, right lateral sections and posterior lobe. Right apical margin, other margins, seminal vesicles, and 7 pelvic LN negative for malignancy.
For cases diagnosed 1998-2003:
For the example above, code the EOD-Pathologic Extension field to 34 [extending to apex] because most of the right side is involved.
The pathology report says all margins are free. The comment on residual tumor in the urethra, meant the first surgery did not completely remove tumor tissue from the urethra, it does not mean that tissue is at the margin.
EOD-Size of Primary Tumor--Breast: When the pathology report does not specify dimensions for the invasive component, how is tumor size coded? See discussion.
In some cases the tumor has both invasive and in situ components. The pathologist sometimes does not report the size for the invasive portion of the tumor. In most cases, the invasive portion is described as a percentage of the tumor mass.
From January 1, 1998 and forward: Follow the Revised Breast EOD instructions. If the size of the invasive component is not given, record the size of the entire tumor in the EOD-Size of Primary Tumor field. Assign the appropriate EOD-Extension code for the situation.
Behavior Code--Bladder/Lymphoma: Should the "in situ" designation on a bladder primary's pathology report be ignored that states a diagnosis of "in situ lymphoma"?
Ignore the in situ designation. You cannot assign an in situ behavior code to a lymphoma primary. The term or designation of "in situ" is limited to solid tumors; carcinoma and/or cancer.
