Code microwave tumor ablation as surgery. For lung, assign code 15.

This question was discussed by the technical advisory group – a small group of representatives from each standard setter which meets periodically. The group agreed on this consensus answer.

Assign code 41 with 1 in surgery other site for simple mastectomy. Assign code 76 with 0 in surgery other site for a more extensive mastectomy.

Do not record XGEVA when given for bone mets from prostate cancer.  See SEER*Rx for more information.

Code metronomic chemotherapy as chemotherapy. Metronomic chemotherapy, also referred to as low-dose metronomic (LDM) chemotherapy, is an emerging cancer treatment approach which administers relatively low doses of traditional chemotherapy drugs over a long period of time and without ‘breaks’ in treatment. By using lower doses this method of treatment minimizes the side effects of traditional chemotherapy.

Note: Answer verified Sept. 2019, still valid for current cases.

Code all mets at diagnosis fields to 0 when the Stage is I, II, or III.

When the lymphoma is Stage IV, one of the mets at dx fields (other than Mets at Dx-Distant lymph nodes) needs to be coded to 1. Stage IV indicates that there is multiple extralymphatic organ involvement, diffuse involvement of an organ; liver, brain, lung or bone involvement, or bone marrow involvement.

For bone, brain, liver, and lung, code these as 1 when these sites are involved and they are not the primary site. This is the same instruction for solid tumor neoplasms.

For mets at dx-distant lymph nodes, always code to 0. For lymphomas, lymph node involvement is included in stage and not based on whether they are regional or distant.

For mets at dx-other, code to 1 for bone marrow involvement or if there is multi extralymphatic organ involvement.

There is a similar question in the FORDS forum of the CoC CAnswer Forum. CoC is the curator for the surgery codes.

Surgical Procedure to Primary Site - Gross excision of the lesion, code in 30s series

Surgical Procedure to Other Site (removal of eye) - code 4

Code histology to 8010/3.

NUT carcinoma is identified by the NUTM1 gene rearrangement.  

NUT midline carcinomas (NMC) are lethal and morphologically indistinguishable from other poorly diff carcinomas. They are epithelial tumors which can range from undifferentiated carcinomas to carcinomas with prominent squamous differentiation.

A new proposed ICD-O-3 code has been suggested for NUT tumors but it is not yet approved for implementation. Do not use the new code until it is approved for use in the United States.

Yes, abstract this as two separate primaries, an invasive melanoma of unknown primary site and an in situ melanoma of the skin on the tip of the nose. Rule M3 applies.

Thalamic amyloidoma is not reportable. Amyloidoma (tumoral amyloidosis, amyloid tumor) is a tumor-like deposit of amyloid. It is not neoplastic. Amyloid is a protein derived substance deposited in various clinical settings.

This case is not reportable based on the information provided. The histologic diagnosis is "metastatic histologically benign smooth muscle neoplasm." The physicians seem to agree with the histologic diagnosis, benign metastasizing leiomyoma (BML). The WHO classification and ICD-O-3 assign 8898/1 to "metastasizing leiomyoma." WHO states "This resembles a typical leiomyoma but it is found in the lungs of women with a history of typical uterine leiomyomas." A recent article states "Because of the hormone-sensitive characteristics of BML, treatments are based on hormonal manipulation along with either surgical or medical oophorectomy." Tamoxifen treatment is in keeping with the BML diagnosis.
