Reportability--Brain and CNS: Is benign neural tissue compatible with a glioneuronal hamartoma of the cerebellopontine angle reportable?
No. A glioneuronal hamartoma is not neoplastic and not reportable. See page 2 of the 2004 SEER Program Coding and Staging manual for the list of reportable brain/CNS tumors. There is no ICD-O-3 code for hamartoma.
Reportability--Skin: Is this case not reportable if the intranasal polyp is covered with cutaneous epithelium (essentially skin) or, is it reportable as a primary intranasal basal cell carcinoma? I have found one article regarding primary intranasal basal cells, which are described as being "very rare". But, I am not sure whether, in those cases, cutaneous epithelium was found.
FINAL DIAGNOSIS: (A) Nasal cavity, polyp, excision: Sinonasal inflammatory polyp with overlying cutaneous epithelium showing foci of superficial (noninvasive) basal cell carcinoma
Report this case as a basal cell carcinoma, noninvasive, of the nasal cavity, based on the information provided.
The polyp was removed from the nasal cavity (C300) which is a reportable site for basal cell carcinoma.
Diagnostic confirmation--Heme & Lymphoid Neoplasms: Is Diagnostic Confirmation coded as 5 (positive laboratory test/ marker study) or code 8 (clinical diagnosis only) for a case that has a positive JAK2 mutation, and based on the results of the JAK2, the physician diagnosed the patient with polycythemia vera? There were no blood smears or bone marrow biopsies done.
Assign diagnostic confirmation code 5 for a positive laboratory test/marker study. A note was added to the Hematopoietic manual to state that code 5 now includes cases with no histological confirmation but there is positive immunophenotyping or genetic studies.
Reportability--Brain and CNS: Are spinal schwannomas and neurofibromas reportable or non-reportable?
The most accurate and most current instruction is to report these spinal tumors when they arise within the spinal dura or spinal nerve roots, or when they are stated to be "intradural" or "of the nerve root." Do not report these tumors when they arise in the peripheral nerves. The peripheral nerves are the portion of nerve extending beyond the spinal dura.
Primary Site--Liver: What is the topography code for combined hepatocellular carcinoma/cholangiocarcinoma (M-8180/3) especially when there is no documentation that intrahepatic bile duct is the tumor site? Reports usually just indicate a liver mass(es) but since the intrahepatic ducts are within the liver, is the code C221 due to the cholangiocarcinoma component, thus making the case stageable?
If there is no further information about where the cancer originated, assign C220. Use ICD-O-3 as the source for coding topography. The topography code associated with combined hepatocellular and cholangiocarcinoma (8180/3) is C220 when there is no other information available, according to ICD-O-3.
CS Extension--Retinoblastoma: When the degree of extension differs between the retinas, how is extension coded for simultaneous bilateral retinoblastoma?
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 the CS extension code that corresponds to the greatest level of extension seen in either eye, excluding information from enucleation.
Record extension based on enucleation in Site Specific Factor 1.
Record bilateral disease under laterality. For retinoblastomas, bilaterality is not a component or consideration for staging.
First Course Treatment/Surgery of Primary Site--Breast: How is "Goldilocks," also referred to as oncoplastic reconstruction, in the surgery section for breast cancer patients coded?
Code Goldilocks mastectomy in Surgery of Primary Site. Breast surgery code 30 seems to be the best available choice for "Goldilocks" mastectomy. It is essentially a skin-sparing mastectomy with breast reconstruction. The choice between code 30 and codes in the 40-49 range depends on the extent of the breast removal. Review the operative report carefully and assign the code the best reflects the extent of the breast removal.
Primary Site--Heme & Lymphoid Neoplasms: How is the primary site coded for a B-cell lymphoma intermediate between diffuse large B-cell lymphoma and Burkitt lymphoma when a biopsy of the paraspinal muscle and epidural tissue is positive, but there is no indication of lymph node involvement in the chart?
Code the primary site to soft tissue of the back, NOS [C496] per Rule PH24 and the Abstractor Notes in the Heme DB for B-cell lymphoma intermediate between diffuse large B-cell lymphoma and Burkitt lymphoma.
Code the primary site to the organ when lymphoma is present only in an organ. The lesion is described as epidural (tissue surrounding the dura) and involving paraspinal muscle, NOS. Both are connective or other soft tissues of the trunk, NOS [C496].
B-cell lymphoma intermediate between diffuse large B-cell lymphoma and Burkitt lymphoma is a synonym for DLBCL 9680/3. When there is no primary site listed in the Heme DB, go to the Abstractor Notes. In the Abstractor Notes section it states that patients present with lymphadenopathy OR mass lesions in extranodal sites.
