MP/H Rules/Histology--Colon: If a tubulovillous (TV) adenoma is in situ and other polyp(s) have an invasive component, does the in situ TV adenoma still have priority and should rule H18 be applied?
For cases diagnosed 2007 or later, always give precedence to coding the invasive. Rule H18 applies UNLESS the adenocarcinoma in the TV is in situ and the others are invasive. In this case, code the histology of the invasive adenocarcinoma.
This clarification will be added when the MP/H manual is revised.
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).
Ambiguous terminology/Reportability--Heme & Lymphoid Neoplasms: Is a physician diagnosis of "appears to be a myeloproliferative disorder" reportable if the patient has no treatment and the physician elects to follow the patient with CBC's?.
Yes. This is a reportable diagnosis and should be accessioned with the histology coded to 9975/3 [myelodysplastic/myeloproliferative neoplasm, unclassifiable].
The word is a reportable ambiguous term per the Hematopoietic Coding Manual (Case Reportability Instructions, Rule 4).
Myeloproliferative disorder is synonymous with myeloproliferative disease. Myeloproliferative disease is listed as an alternate name for myelodysplastic/myeloproliferative neoplasm, unclassifiable.
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.
EOD-Extension/EOD-Lymph Nodes--Rectosigmoid: How do you code these fields for a scan-based clinically staged T3 N1 rectosigmoid primary in a patient who received chemotherapy and radiation prior to a resection that demonstrated invasion only into the muscularis and no positive lymph nodes?
For cases diagnosed 1998-2003:
Use the best information available, in this case, the clinical staging, to code EOD. Code the EOD-Extension field to 40 [Invasion through muscularis propria or muscularis, NOS] and the EOD Lymph Node field to 3 [Regional lymph node(s) NOS] because the case had a clinical stage of T3 N1. EOD is coded using the most extensive clinical or pathologic stage.
EOD-Clinical Extension--Prostate: Note 8 of the clinical EOD scheme for prostate states, "B1, Small, discrete nodule(s)<1.5 cm, and B2 Nodule(s)>1.5 cm ... " Does Note 8 still apply for cases diagnosed 1998 or later?
For cases diagnosed 1998-2003:
Note 8 in the EOD scheme does not apply because nodule size does not apply in the 5th or 6th edition of TNM.
EOD-Size of Primary Tumor--Lung: Can tumor size of 002 [Malignant cells present in bronchopulmonary secretions] be used when there is a lung mass seen but the diagnosis is from a positive bronchopulmonary secretion?
For cases diagnosed 1998-2003:
EOD-Size of Primary Tumor code 002 [Malignant cells present in bronchopulmonary secretions] is used only when there is no visible primary lung tumor and bronchopulmonary secretions are positive for lung malignancy.
Even if the diagnosis was made by cytology of broncho-pulmonary secretions, if there is a visible mass, code the size of the mass if known, code 999 if size is unknown.
Date of Diagnosis--Bladder: Should the date of diagnosis be based on the 1/7/04 urine cytology with low grade transitional cell carcinoma or the subsequent 1/27/04 pathology findings of papillary transitional cell carcinoma?
In this case, the date of the cytology is the date of diagnosis, 01-07-2004.
Histology (Pre-2007)--Skin: Are "atypical melanocytic hyperplasia" and "severe melanotic dysplasia" synonyms for melanoma in situ?
For tumors diagnosed prior to 2007:
No. SEER determines its reportable list from the ICD-O-3. The above terms are listed as tumor-like lesions and conditions, but are not in situ or malignant.
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/Other therapy--Skin: How is PUVA [psoralen (P) and long-wave ultraviolet radiation (UVA)] coded when used for skin primaries such as melanoma and mycosis fungoides?
Code PUVA as "Other treatment" with Code 1 - Other. We do not have a code specifically for ultraviolet radiation.
