Surgery of Primary Site--Rectum: How do you code a procedure described as a "transanal resection, debulking of a large rectal mass"? See Discussion.
Patient is not a surgical candidate due to "other medical conditions". Colonoscopy done for anemia and rectal bleeding. At the colonoscopy a "Transanal Resection Debulking of large rectal mass" is performed. Two specimens are sent to the lab. The first is labeled "rectal mass" and is a 2.0 cm diameter spherical fragment of tissue. The second is labeled "transanal debulking rectal mass" and is described as multiple, irregular shaped fragments of tan, rubbery tissue measuring 5.0 x 5.0 x 3.0 cm. Final path diagnosis: Debulking of rectal mass: Adenocarcinoma greater than 2 cm in size, resection margins positive for tumor.
For cases diagnosed 1998-2002, code Surgery of Primary Site to 20 [Local tumor excision, NOS]. Because the procedure was performed via colonoscopy and apparently did not involve proctectomy, the best choice is a local excision.
Ambiguous Terminology/Reportability: Are the terms "bordering on" and "may represent" diagnostic of cancer? See Discussion.
Pathology report states "...florid micropapillary hyperplasia, focally atypical with features bordering on low grade micropapillary ductal carcinoma in situ."
The terms "bordering on" and "may represent" are not diagnostic of cancer. These terms are not on the list of ambiguous terms that constitute a diagnosis of cancer. The diagnosis in the example above is not reportable to SEER.
First Course Treatment/Immunotherapy--Colon: Can "Sandostatin" be coded for treatment of carcinoid tumors of the colon because it flushes tumor cells from the colon in addition to controlling diarrhea?
Do not code Sandostatin (Ocreotide Acetate) as treatment. This is an ancillary drug used to treat symptoms of diarrhea. SEER Book 8 is undergoing revision and will include this change.
CS Lymph Nodes/CS Reg Nodes Eval -- Rectum: If the rectal tumor is not treated with a resection but on endoscopic ultrasound the patient is stated to have a lymph node above the primary tumor and the physician stages the case clinically as N1, should the CS Lymph Nodes field be coded to 30 [Regional lymph node(s), NOS] or 10[Rectal, NOS]? Should the evaluation field be coded to 0 [No lymph nodes removed. Evidence based on other non-invasive clinical evidence] or 1 [No lymph nodes removed. Evidence based on endoscopic examination.]? See Discussion.
Rectal primary:
5/04 sigmoidoscopy w/bx of rectal mass: adenocarcinoma. 6/04 Endoscopic ultrasound of rectal mass: invasion through wall but no definite invasion of prostate or seminal vesicles; 7.5mm lymph node located above tumor, no other enlarged lymph nodes detected. Patient did not have surgery. Physician staged lymph node involvement to clinical N1.
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.Assign CS Lymph Nodes code 10 [Regional lymph nodes] based on the physician's N1. Assign code 10 because it is the lowest numerical CS code that corresponds to N1 in the scheme for rectum. Use the physician's assignment of TNM when the information in the medical record is incomplete or ambiguous. Code CS Reg Nodes Eval field 0 [No lymph nodes removed] for the case described above because there is no indication that N1 was assigned based on the endoscopic exam. The NI may be based solely on TNM documentation provided by the clinician and you do not know what the clinician used as the basis for the staging.
Primary Site/Grade, Differentiation, Cell indicator--Lymphoma: Will a Grade, Differentiation code of 6 [B-cell] for a lymphoma coded to primary site C80.9 [unknown] fail edits? See Discussion.
Patient had a large mass in chest wall that was excised and found to be large B cell lymphoma. Scans mentioned no involvement of lymph nodes but indicated nodules in the liver thought to be lymphoma as well.
For cases diagnosed prior to 1/1/2010:The combination of a primary site C809 with a Grade, Differentiation code of 6 when used for a lymphoma will not fail SEER edits. Avoid coding primary site to C809 when possible. Code primary site for the example above to C761 [Chest wall, NOS]. The chest wall is the only area of involvement, except for "liver nodules." Liver is an unlikely primary site for lymphoma.
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.
Reportability/Behavior Code--Melanoma: If a dermatologist states a "proliferation of atypical melanocytes confined to epidermis" is melanoma in situ, is it reportable to SEER?
For this case only, it is reportable to SEER because the physician states that it is "melanoma in situ."
The phrase "proliferation of atypical melanocytes confined to epidermis" alone is not reportable to SEER. This phrase means that there are a number of (proliferation) pigmented cells (melanocytes) not showing the normal cell structure (atypical).
CS Tumor Size/CS Extension/CS TS/Ext-Eval--Breast: How do you code these fields when the tumor size and extension differ pre and post treatment with neoadjuvant Arimidex? See Discussion.
Clinically on PE 3 cm mass attached to skin with dimpling and erythema overlying the mass. Ultrasound: 2-3 cm breast mass with overlying skin thickened by US evaluation, suggesting dermal invasion. Neoadjuvant Arimidex followed by MRM. Path: 4.5 cm ductal carcinoma (no DCIS), no invasion of skin.
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.Record the larger tumor size and the farthest extension documented.
Code CS Tumor Size/Extension Evaluation to 6 [Surgical resection performed, WITH pre-surgical systemic treatment...; tumor size/extension based on pathologic evidence].
Code CS Tumor Size for the example to 045 [4.5 cm].
Code CS Extension to 20 [Local skin involvement ...] based on clinical description provided.
Reportability--Brain and CNS: Is a skull tumor schwannoma an intracranial reportable benign tumor if the physician states it arose in the occipital nerve?
No. These schwannomas are not intracranial and therefore, are not reportable to SEER. The occipital nerve is not one of the 12 intracranial nerves (i.e., Abducens, Auditory (vestibulocochlear), Facial, Glossopharyngeal, Hypoglossal, Oculomotor, Olfactory, Optic, Spinal Accessory, Trigeminal, Trochlear, and Vagus).
