Multiple Primaries (Pre-2007)--Testis: How many primaries should be reported when seminoma is diagnosed simultaneously in both testicles and both tumors are encapsulated?
For tumors diagnosed prior to 2007:
Report this cases as two primaries, unless there is information in the record confirming one primary.
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--Kidney: If a "tumor thrombus" in a renal vein is discontinuous from the primary tumor in the kidney, is it still coded to 60 [Tumor thrombus in a renal vein, NOS], rather than 85 [Metastasis]?
For cases diagnosed 1998-2003:
Code the EOD-Extension field to 60 [Tumor thrombus in a renal vein, NOS]. A thrombus can be a bolus of tumor cells within a large vein that may or may not still be connected/contiguous with the primary tumor. However, both a discontinuous and contiguous thrombus are coded to 60.
Grade, Differentiation--All Sites: What code is used to represent this field when a pathology report describes a tumor as a low grade neoplasm consistent with a specific histologic type (e.g., Low grade neoplasm consistent with carcinoid)?
Code the Grade, Differentiation field to 2 [Low grade].
EOD-Extension: The medical record lacks a clear statement that metastatic workup was complete. A metastatic deposit is identified within 4 months of diagnosis and while the patient is undergoing first course of treatment. How do you code the EOD-Extension field?
For cases diagnosed 1998-2003:
In coding the EOD-Extension field, ignore metastasis that is discovered after the initial workup is completed regardless of the timeframe from diagnosis date until the date the metastatic deposit was discovered. The metastasis is progression of disease.
Any of the following represents progression of disease. Do not code the subsequently identified metastatic involvement in the EOD:
1) The metastatic workup was complete and treatment started before the procedure was done that found the metastatic involvement.
2) A procedure, such as a scan, was negative initially and a repeat of that procedure is now positive.
3) The treatment plan is developed for a localized disease process.
If you are unable to determine whether the newly discovered metastasis represents progression or is part of the initial workup, regard the metastasis as progression. Do not code the metastasis in the EOD-Extension field.
Multiple Primaries (Pre-2007)--Bladder: Is a 1998 transitional cell carcinoma of the bladder, followed by a 2001 squamous cell carcinoma of the bladder reportable as a second primary?
For tumors diagnosed prior to 2007:
Yes. This case is reportable as a second primary. The rule in the SEER Program Code Manual says that invasive bladder cancers with histology codes 8120-8130 [papillary, transitional] are always coded as a recurrence and are an exception to the multiple primary rule. Squamous cell carcinoma [8070] is not a part of that exception.
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.
First Course Treatment: 1) When is Decadron (Dexamethasone) coded as cancer treatment? 2) When Decadron is given to a patient with multiple myeloma, is it coded as treatment only if given in combination with chemotherapy? See discussion.
SEER Book 8 states that Decadron is an important therapeutic agent for treatment of multiple myeloma. In the Abstracting and Coding Guide for the Hematopoietic Diseases, Decadron is a hormonal treatment for multiple myeloma "when given as part of a chemotherapy regimen".
For cases diagnosed 1/1/2003 and after:
1. Code hormone therapy to 01. Code any therapy administered to treat cancer tissue that achieves its effect on cancer tissue through a change in the hormone balance in the hormone therapy field. Decadron is coded for leukemias, lymphomas and multiple myelomas primaries. It is coded for other sites only when stated to be cancer-directed treatment.
2. Code hormone therapy to 01. Decadron should be coded as hormone therapy for multiple myeloma when given alone or as part of a first course of treatment chemotherapy regimen.
Surgical Procedure of Other Site--Pancreas: Should an embolization of liver metastasis for a pancreas primary be coded as treatment?
Code "embolization" (or hepatic artery embolization, HAE) to a metastatic site in Surgical procedure of Other Site. Assign code 1 [nonprimary surgical procedure performed].
This procedure was previously coded as other therapy, experimental. Code as surgery as of July 2005.
SEER Guidelines Over Time: Should we apply the current guidelines to previously missed older cases now being reported to the central registry? See discussion.
1. We receive "straggler" cases for coding that were diagnosed when previous coding schemes and guidelines were applicable. When a specific guideline is in place for a given time period and is later changed in some way, we try to use the specific guideline that was in place at the time of diagnosis when coding the incoming case. However, it is not always possible to remember or to be able to access those old guidelines.
2. There are situations when coding old cases that have no applicable guideline for the older diagnosis years but current SEER documentation informs the coder how to handle the situation. For example, in the SEER Program Code Manual (3rd ed), 3 new guidelines were added for coding of differentiation. There were no guidelines in the previous SEER manual that specifically covered those situations. Should we use the current rules in coding differentiation on the older incoming case?
Code all fields according to the instructions that were in effect at the time the case was diagnosed. If the old guidelines are unavailable or non-existent, code the case in the current scheme. The year the case was abstracted will indicate that the case was a late entry into the system and that could account for the differences in coding seen by a reviewer.
CS Extension/CS Lymph Nodes--Breast: How would you interpret the phrase "axillary lymph node tissue, not clearly a lymph node" or the phrase "satellite nodule of invasive tumor, left axillary lymph node or chest wall tissue"? See discussion.
A lumpectomy with axillary lymph node dissection and removal of nodule in anterior axillary line revealed negative lymph nodes. The nodule specimen was labeled "axillary lymph tissue, not clearly a lymph node". The microscopic description for that specimen stated "Fibroadipose tissue. A fragment of a lymph node is incidentally sampled in block 4 and it is free of tumor". The final path dx stated "Satellite nodule of invasive tumor, left axillary lymph node, or chest wall tissue. Comment: If the tissue is considered chest wall this would be a stage IIIB. If it is considered an intramammary satellite nodule, this is a stage I". The clinician repeated what the comment said, and added "If lymph node mets, this is a stage II."
Code the invasive tumor in the axillary area as a regional lymph node metastasis. According to the AJCC, cancerous nodules in the axillary fat adjacent to the breast, without histologic evidence of residual lymph node tissue, are classified as regional lymph node metastases.
Scope of Regional Lymph Node Surgery--Breast: How should this field be coded when a mastectomy that removed 3 sentinel lymph nodes is later followed by an axillary lymph node dissection that removed 17 lymph nodes? Should all of the lymph node information be coded to this field, even though the Number of Regional Lymph Nodes Examined field will be coded to the number of lymph nodes from the most definitive surgery (17)?
For cases diagnosed 1/1/2003 and after: Yes, all of the lymph node information should be coded to the Scope of Regional Lymph Node Surgery field using code 7 [Sentinel node biopsy and code 3, 4, or 5 at different times].
The Number of Regional Lymph Nodes Examined field no longer exists for this time frame.
