Surgery of Primary Site--Breast: How is this field coded when a patient has a reduction mammoplasty (for macromastia) and within the pathology specimen there is an incidental finding of carcinoma?
Code this reduction mammoplasty to the code which best fits the amount of tissue removed. Read the operative report carefully. Code as a partial mastectomy, skin- nipple- areola-sparing mastectomy, or total (simple) mastectomy. Use text fields to record the details.
Histology (Pre-2007)--Stomach: What code is used to represent the histology of "mucin-secreting adenocarcinoma, intestinal type "for a stomach primary?
For tumors diagnosed prior to 2007:
For this specific example, code histology to 8481 [Mucin-producing adenocarcinoma] as it is a more specific cell type with inherent prognostic information.
Code 8255/3 [Adenocarcinoma with mixed subtypes] is not appropriate for this case because "intestinal type" is a more specific description of this cancer and not another type of cancer. There are two broad categories of gastrointestinal adenocarcinomas: Intestinal and Diffuse.
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.
Ambiguous terminology/EOD-Extension: Is the term "within" a term of involvement in coding extent of disease? See Description.
For example: a kidney tumor is described as "completely encased within the renal capsule with no extension into perirenal fat." Does this mean the renal capsule has been invaded (extension code 20) or that the tumor is totally contained within an area surrounded by the renal capsule (extension code 10)?
For cases diagnosed 1998-2003: The term "within" is not one of the listed ambiguous terms for EOD. Determine extent of involvement from the context in which "within" appears.
In the example, "Encased" is an ambiguous term meaning not involved. Code extension for the example to 10 [Invasive cancer confined to kidney cortex and/or medulla].
Primary Site/Histology (Pre-2007)--Bone: How are these fields coded for a squamous cell carcinoma in bone? See Description.
The consult path report says "I believe that there is definitely high grade malignant tumor in this amputation specimen, and that this tumor represents an invasive squamous cell carcinoma, which is extending into the bone and permeating in between the bone trabeculae. ... The fact that squamous cell carcinoma can arise from the sinuses of chronic osteomyelitis is well recognized."
For tumors diagnosed prior to 2007:
Based on the information provided, code the primary site as C40._ or C41._ [bone] because the tumor originated in the sinuses of chronic osteomyelitis. Code to the site in which the tumor arises. Override the SEER site/histology edits to allow this rare combination of bone and squamous cell carcinoma.
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.
Primary site: How is this field coded for a malignant spindle cell neoplasm in a subcutaneous mass of the right knee? See Description.
The pathology report says: Right knee tumor:
A. discrete subcutaneous mass 3.5x5.2x1.4 cm malignant spindle cell neoplasm (see Comment)
B. A focus of subcutaneous malignant neoplasm is identified in the superior resection margin.
C.All other margins are clear.
The comment mentions that the specimen has been sent to Mayo Clinic and the Mayo clinic consult says, "we still believe that the diagnosis of spindle cell carcinoma is correct. Obviously the differential diagnosis involves melanoma and sarcoma also. The results of the immunoperoxidase stains strongly support the prior diagnosis of a carcinoma."
Code the site to C49.2 [Connective, subcutaneous and other soft tissues of lower limb and hip]. The site is a subcutaneous mass. C49 with 8032/3 will not be impossible following the next updates to the SEER edits.
EOD-Size of Primary Tumor: Can the term "filling defect" be used to code tumor size? See Description.
Site: Bladder
CT abd/pelvis: 4 cm filling defect of the bladder encasing jetstream of distal ureter. 2-3 cm lesion may be extension to bladder. KUB: 3-4 cm filling defect within bladder.
Cystoscopy: large bladder tumor with small tumor extending out of the large tumor.
OP Findings: Large tumor on right of bladder extending from bladder neck lateral and posterior
Pathology: TURB: High grade TCC, Grade III with focal lamina propria invasion.
For tumors diagnosed 1998-2003:
Information on size from imaging/radiographic techniques can be used to code size when there is no more specific size information from a pathology or operative report, but it should be taken as low priority, just above a physical exam.
The term "filling defect" from a CT or KUB may be used to code tumor size for bladder in the absence of more reliable size information from path, operative or endoscopic reports.
First Course Treatment/Radiation Therapy/Immunotherapy--Thyroid: For this primary, do we code I-131 as a Radio-isotope as well as a Biological Response Modifier? See Description.
(SEER Book 8 lists I-131 as a Biological Response Modifier.) Immunoglobulin is listed as immunotherapy agent in the CCR manual also coded as immunotherapy. Are there two different types of I-131, immunoglobulin and sodium iodide?
Sodium Iodide is listed as an ancillary drug in SEER Book 8, page 45. The listing on page 63 refers to Antiferritin antibody, or AntiCEA. Both of these were under clinical investigation when Book 8 was written. They are no longer active and this change will be made when Book 8 is revised.
Ambiguous Terminology/Histology (Pre-2007): How do we code histology when there is a difference between the histology mentioned on a suspicious cytology and the clinical diagnosis by the treating physician? See Description.
An FNA of pancreas is stated as "highly atypical cells present, suspicious for pancreatic ductal carcinoma." The attending physician states the patient has pancreatic carcinoma. Can histology be coded 8500/3 [infiltrating duct carcinoma, NOS] or should it be 8010/3 [carcinoma, NOS]?
For tumors diagnosed prior to 2007:
Code the histology from a suspicious cytology when this histology is supported by the clinical diagnosis.
Code the example above to 8010/3 [Carcinoma, NOS].
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/Surgery of Primary Site--Melanoma: If a melanoma primary site is other than skin, vulva, penis, or scrotum should these fields be coded using melanoma schemes? See discussion.
Should a melanoma of the cervix be coded using the melanoma or the cervix schemes for these fields?
For cases diagnosed 1998-2003: Use the EOD and surgery code schemes for cervix uteri. The EOD scheme for melanoma excludes melanoma of the cervix uteri. The surgery code scheme for skin excludes cervix uteri.
Reportability/Terminology, NOS--Hematopoietic, NOS: Are the diagnoses "myelodysplastic syndrome," "myelodysplastic syndrome, thrombocytopenia" and "myelodysplastic syndrome, anemia" all reportable to SEER for diagnosis 2001 and later?
For cases diagnosed prior to 1/1/2010:"Myelodysplastic syndrome" (NOS) is reportable to SEER--ICD-O-3 code 9989/3. "Myelodysplastic syndrome, thrombocytopenia" is not reportable to SEER because "thrombocytopenia" is not reportable. "Myelodysplastic syndrome, anemia" is not reportable to SEER because "anemia" is not reportable.
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.
