Histology (Pre-2007)/Primary Site/EOD-Extension--All Sites: How do you code these fields for a resected thyroid that is negative for any diagnostic abnormality and a left ovary that demonstrates "papillary thyroid carcinoma arising in a cystic teratoma"? See discussion.
Teratomas occurring in the ovaries frequently contain various types of fully differentiated tissue that normally occur in other body parts. Should the primary be coded to the ovary or to the organ in which that type of tissue normally occurs?
For tumors diagnosed prior to 2007:
Code the Primary Site field to the organ in which the cancer arose. For this tumor, code the Primary Site field to C56.9 [ovary] and Histology to 8260/3 [papillary carcinoma of thyroid]. Use the ovary EOD for tumors diagnosed 1998-2003.
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.
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.
Surgery of Primary Site--Soft Tissue: What code is used to represent this field when an excisional biopsy of a soft tissue sarcoma is followed two weeks later with a wide excision (re-excision)?
For cases diagnosed 1/1/2003 and after: Code the Surgery of Primary Site field to 26 [partial resection]. According to the CoC, "Excision" in the surgery codes refers to the lesion and "partial resection" refers to the organ. The biopsy is a local excision (code 25). The wide resection is code 26, presuming that more than just the remaining lesion was removed.
Reportability--Hematopoietic, NOS: Should we add the missing terms listed in the Abstracting and Coding Guide for the Hematopoietic Diseases to ICD-O-3 because these absent synonyms would not be identified during hematology casefinding? See discussion.
The Abstracting and Coding Guide for the Hematopoietic Diseases gives a preferred term for each code followed by a list of synonyms, not all of which are listed in the ICD-O-3. Two examples are: 1) 9962/3 [Essential Thrombocythemia] has 6 synonymous terms listed, but the last three of them are not in ICD-O-3. 2) 9930/3 [Myeloid Sarcoma] has the synonym "extramedullary myeloid tumor" which is not in ICD-O-3.
For cases diagnosed prior to 1/1/2010:Do not add these synonyms to ICD-O-3. The Abstracting and Coding Guide for the Hematopoietic Diseases lists synonyms for the preferred terms to assist in the classification of these other terms. In the absence of a specific code for the synonym, code to the preferred term. For casefinding, these terms would be grouped in a broader category of hematologic diseases under an ICD-9-CM or ICD-10 code and, therefore, will be identified during casefinding procedures using the disease index.
For cases diagnosed 2010 forward, refer to the Hematopoietic and Lymphoid Neoplasm Case Reportability and Coding Manual and the Hematopoietic Database (Hematopoietic DB) provided by SEER on its website to research your question. If those resources do not adequately address your issue, submit a new question to SINQ.
EOD-Extension--Lung: How do you code extension for a lung tumor described on bronchoscopy as "obstructing the RUL and intruding into the right bronchus intermedius. Small tumor nodules distally in midline of anterior trachea wall"?
For cases diagnosed 1998-2003:
Code the EOD-Extension field to 85 [Metastasis] because the tumor nodules are discontinuous from the primary tumor.
EOD-Extension--Urinary Tract: Can the rules used to code bladder extension involving the term "no involvement of muscularis/and no mention of subepithelium/submuscosa" be used to code extension for other urinary tract primaries, such as ureter?
For cases diagnosed 1998-2003:
No. The inferred descriptions of noninvasion apply to bladder cases only.
Multiple Primaries (Pre-2007)--Kidney: How many primaries are reportable in a patient treated with a bilateral nephrectomy that revealed multiple tumors within each kidney and the histology in both the left and the right kidney was "renal cell carcinoma, indeterminate type: multiple histologically identical tumors" and the clinical discharge diagnosis was "bilateral renal cell carcinoma, probably surgically cured"? See discussion.
The SEER manual states "If only one histologic type is reported and if both sides of a paired site are involved within two months of diagnosis, a determination must be made as to whether the patient has one or two independent primaries." Frequently, the only statement we have is that "bilateral organs are involved." Additional guidelines for determining number of primaries would be helpful.
For tumors diagnosed prior to 2007:
Report this case as two primaries, left and right kidneys. According to our pathologist consultant, "The description sounds like bilateral multiple primaries. Multicentricity in the same kidney occurs in about 4% of all cases, and bilaterality in 0.5 to 3% (Atlas of Tumor Pathology, Tumors of the Kidney, Bladder, and Related Urinary Structures)."
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-Lymph Nodes--Head & Neck: When a physician provides only "Stage IV" (i.e., an abbreviated stage) for a right posterior tongue primary with lateral extension into the oropharynx and hypopharynx, can you assume "palpable" level 2, 3 and 5 lymph nodes are involved?
For cases diagnosed 1998-2003:
Code the EOD-Lymph Nodes field to 9 [Unknown], based on the information provided.
The physician's statement of an N category from a TNM may be used to determine lymph node involvement in the absence of other information. However, you cannot assume nodal involvement based on the incomplete staging information of "Stage IV" for a base of tongue primary. For this primary site, extension into the hypopharynx from this primary is equivalent to T4/Stage IV. Therefore you cannot assume the clinician's assessment of the case as Stage IV represents his assessment of lymph node involvement.
Histology (Pre-2007): What code is used to represent a review of slides histology of "in situ squamous cell carcinoma and multiple detached fragments of atypical papillary squamous epithelium; highly suspicious for invasive carcinoma"? See discussion.
The original pathologist indicated a final diagnosis of moderately differentiated squamous cell carcinoma. The slides were sent for review to another facility. The reviewing pathologist rendered the diagnosis stated in the question section.
For tumors diagnosed prior to 2007:
Code the Histology field to 8070 [squamous cell carcinoma].
The review diagnosis was also squamous cell carcinoma. The expression "atypical papillary squamous epithelium" does not modify the cancer histology.
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: If extension/metastasis is found within 4 months of diagnosis, but after first course of cancer-directed therapy has ended, should that involvement be excluded when coding the EOD-extension field? See discussion.
Example: Spinal drop metastasis was diagnosed within 4 months of the initial diagnosis of a localized astrocytoma, but after treatment with surgery and XRT was completed.
For cases diagnosed 1998-2003:
Do not include the spinal metastasis because it was diagnosed after the extent of disease was established. If metastasis was not present at diagnosis, and not discovered during the original metastatic work-up, it is progression of disease.
