2004 SEER Manual Errata/CS Lymph Nodes--Head & Neck: On page C-353, in the supraglottic larynx schema, there is no mention of Level IV nodes in the CS Lymph Node codes.
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.The CS Steering Committee is aware of this issue and is working to resolve it.
Multiple Primaries (Pre-2007): How many primaries? See Discussion.
5/05 perianal skin bx, 6/05 mapping bx perianal skin, 9/05 punch bx perianal skin: all positive for extramammary Paget Disease. 9/05 Perianal Excision of Paget w/V-Y flap repair. Path: Perianal and anal skin: Extramammary Paget disease associated with: Invasive adenoca of anal canal. Anal margins positive for invasive adenoca. Comment: invasive adenoca with local mucinous features involving the anal margin/end of specimen. This adenoca is in continuity with (associated with) extensively diffuse extramammary Paget disease. Unclear whether the adenoca represents a rectal primary with spread to perianal area, anal gland adenoca or mets. 12/05 AP resection-no residual Paget or invasive neoplasm.
For tumors diagnosed prior to 2007:
There is one primary.
Code the histology to 8542 [Paget disease, extramammary]. Code the primary site C210 [anus]. Histology rule 7 on page 87 of the 2004 SPCM applies in this case.
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.
Date of Diagnosis/Histology--Hematopoietic, NOS: How are these fields coded if a 3/17/03 bone marrow biopsy diagnosis of "malignant proliferative disorder" is subsequently confirmed to be a "low grade lymphoma" per a bone marrow biopsy in early 2006? See Discussion.
3-17-03: Bone marrow biopsy from rt iliac crest: Hypercellular marrow (90%) with extensive involvement by lymphoproliferative disorder (see description). Micro: The bone marrow is diffusely (>90%) involved by a malignant lymphoproliferative disorder. This consists of small lymphocytes,histiocytes, and large atypical cells with prominent nucleoli.
12-22-05 Extensive bone marrow involvement by lymphoproliferative disorder, bone biopsy from femur.
1-27-06 Hem/Onc Physician Note:
following pt for a lymphoproliferative disorder. ...bone marrow biopsy 2003, suggestive of, but not truly diagnostic, a lymphoproliferative disorder. Therefore, I elected not to do anything, but just follow her.
3-23-06 Hem/Onc Note:
pt with a history of an apparently low-grade lymphoma involving the marrow, as well as, I believe, the liver and recently pathologically diagnosed as a T-cell-rich B-cell lymphoma. ...followed in the past by Dr. ___ and has never actually had any treatment for this lymphoma, although it is documented even three years ago by bone marrow biopsy.
For cases diagnosed prior to 1/1/2010:
Code the diagnosis date to 3/17/03. The histology code is 9970/3 [Malignant myeloproliferative disorder]. The bone marrow biopsy confirms a "Malignant" lymphoproliferative disorder. Apply ICD-O-3 rule F and assign /3 to histology code 9970.
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--Skin: Is a pilomatrix carcinoma of the skin reportable if it is described as being a malignant diagnosis based on poor circumscription, infiltrative growth pattern, and focal abundant mitoses?
No. Pilomatrix carcinoma is not reportable to SEER. Please see page 1 of the 2004 SEER manual. Skin primaries with histology codes from 8090 to 8110 are not reportable. Pilomatrix carcinoma is coded 8110/3.
Reportability--Anus: Is a final diagnosis on a pathology report of "squamous cell carcinoma of the anus, NOS" assumed to be a skin of anus primary or a primary of the anus?
Squamous cell carcinoma of the anus is reportable unless known or stated to be skin of anus.
Chemotherapy: If a physician does not document the reason chemotherapy was given concurrently with radiation therapy, should it be assumed to have been used as a radiosensitizer or radioprotectant and then, per SEER chemotherapy coding instruction 2, ignore coding the chemo agent as treatment?
Do not assume that a chemo agent given with radiation therapy is a radiosensitizer. Seek additional information.
Compare the dose given to the dose normally given for treatment. When chemotherapeutic agents are used as radiosensitizers or radioprotectants, they are given at a much lower dose.
Diagnostic Confirmation--Leukemia: How is this field coded when the clinician confirms that the diagnosis of CML is based on a combination of the clinical picture and positive cytogenetic studies?
Assign code 1 [Positive histology]. For leukemia only, assign code 1 for positive hematologic findings including peripheral blood smears, CBCs and WBCs.
Cytogenetics studies would have been done on blood. Therefore, histology provided diagnostic confirmation as it would with smear, bone marrow, or other special study of blood cells.
CS Lymph Nodes--Esophagus: Is a resected positive "periesophageal nodule" coded as an involved lymph node for an esophagus primary? See Discussion.
Per SINQ 20000846: Each gross nodule of metastatic carcinoma in the fat surrounding an organ is counted as one positive regional lymph node. SINQ 2000846 applied to EOD. Can this concept be used for Collaborative Stage?
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.
For cases diagnosed on or after January 1, 2004:
Search for additional information on the "nodule." Review the gross and microscopic descriptions to determine whether or not the nodule is a lymph node. If it is not possible to obtain further information, apply the downstaging rule and select the Extension or LN code that results in the lower category.
Histology (Pre-2007)--Bladder: How is a "carcinoma with squamous, mucinous, and signet ring cell features" coded?
For tumors diagnosed prior to 2007:
Code histology to 8490 [Signet ring cell carcinoma]. Rule 7 on page 87 of the 2004 SEER Manual applies to this case.
Rule 7: Code the numerically higher ICD-O-3 code. This is the rule with the lowest priority and should be used infrequently.
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.
CS Extension--Lymphoma: In the absence of physician staging, is an "enlarged" spleen seen on CT coded as involvement of the spleen for lymphoma cases?
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.
Do not code spleen involvement when the only evidence is an enlarged spleen.
When imaging is the only diagnostic tool (no biopsy or splenectomy), spleen involvement is based on the presence of nodules and not on enlargement. Splenic enlargement alone (by physical exam or imaging) is insufficient to support involvement of spleen.
