Primary site--Anus/Anal Canal: What site do you code squamous cell carcinoma of the anal verge?

Assign C211 for anal verge. Anal verge is defined as the lower (distal) end of the anal canal, junction between the skin of the anal canal and the perianal skin, http://www.seer.cancer.gov/manuals/2015/AppendixC/rectosigmoid/coding_guidelines.pdf

20021040 Other Therapy: What code is used to represent treatment with "Epithilone" or "Epothilone"? Code the Other Cancer-Directed Therapy field to 2 [Other experimental cancer-directed therapy (not included elsewhere)], until the exact mechanism of action is determined for this drug. This drug is in phase I clinical trials. It has a similar action to Taxol, but is derived from a different source. N/A Other therapy 2002
20130156 Other therapy--Heme and Lymphoid Neoplasms: Based on the hematopoietic manual instructions, is plasmapheresis coded as treatment for Waldenstrom macroglobulinemia? See Discussion.

A patient, who was diagnosed with Waldenstrom macroglobulinemia at another facility, presented to our facility for plasmapheresis on 12/27/2012. No other treatment was given.

How is the plasmapheresis coded for treatment?

Do not code plasmapheresis as treatment. It does not modify the neoplasm. Heme & Lymphoid Neoplasms Other therapy 2013
20000452 Other Therapy: What code is used to represent "gene" therapy? See discussion.

The following form of gene therapy has been described as treatment for malignant brain tumors.

Patients undergo surgery to remove as much of the tumor as possible. After surgery, the patients are infused with a virus that has been genetically altered so that it is not infectious and so that it contains a gene from the herpes simplex virus. The herpes gene is sensitive to a drug called ganciclovir. Once inside the brain, the genetically altered virus infects any remaining tumor cells. When this occurs, the herpes gene is established inside the cancer cells. After the virus infects the cancer cells, the patients are given ganciclovir. This drug would kill both the virus and the brain tumor cells.

20051110 Other Therapy: Can herbal therapy be coded when used as a single therapy or when used in combination with conventional therapy as a complimentary treatment? See Discussion. Page 201 of the SPCM 2004, item #5, states "Assign code 6 for unconventional methods whether they are single therapy or given in combination with conventional therapy." This statement itself is ok but there is no guideline on the use of complementary therapy when it is given as the only treatment. The SPCM, 3rd editon, page 140 states: "Use code '6' for alternative and complementary therapies ONLY IF the patient receives no other type of treatment." There is no such statement in the SPCM 2004. Assign code 6 for unconventional methods whether they are single therapy (alternative medicine is the only treatment) or given in combination with conventional therapy (complementary medicine plus conventional).

20031210 Other Cancer-Directed Therapy--Hematopoietic, NOS: Is there a hierarchy for selecting which code to use when a patient receives more than one type of "other treatment"? See Description. Patient was diagnosed with Myelodysplastic Syndrome, probably refractory cytopenia with multilineage dysplasia. Good candidate for investigational studies for transfusion-dependent patients. Patient was enrolled in a high dose vitamin D study. Patient also received transfusions.

SEER has not established a hierarchy of the codes listed under Other Treatment. If the patient receives more than one type of other treatment as the first course of treatment, assign the code that provides the most information about how the patient was treated and use the remarks fields to explain.

Code Other Treatment for the case example above as 2 [Other experimental therapy]. Use the remarks fields to describe the transfusions and vitamin D therapy.

SEER Manual/Mets at Diagnosis--Lung: Would calvarium lesions invading the brain be both brain and bone metastasis or only bone metastasis? See Discussion.

Lung cancer, 2022

12/1/2022 PET/CT showed destructive hypermetabolic bone lesions in right frontal and left posterior calvarium. Left posterior calvarium lesion involves portions of left parietal and temporal bones w/invasion of mastoid air cells.

1/4/2023 MRI Brain showed large destructive mass involving left posterior temporal calvarium that extends into left mastoid region and may invade left distal transverse sinus.

2/8/2023 Radiation Oncology follow-up note: MD states there are extensive calvarium metastasis with the left parietal lesion invading the brain causing edema and MS-like changes.

2/13/23 Radiation Oncology Final Letter- Patient was treated with 1 EBRT fraction aimed at brain/skull before enrolling in hospice.

Abstract as bone metastasis for the first two examples. Abstract as both bone and brain metastasis for the third and fourth examples in the respective Mets at Diagnosis fields based on the description provided.

20061128 Marital Status: Is marital status coded to 2 [married] if the patient is legally married to a same-sex spouse (e.g., patient has a Canadian spouse and in Canada, same-sex marriages are legal)? Code marital status for same-sex persons based on the legal status. For the case example above, assign code 2 [married]. N/A Marital Status 2006

Marital Status: Is Marital Status always a self-reported status? See Discussion.

The SEER Manual states that Marriage is self-reported for the instruction in code 2, but it does not indicate if all other marital statuses are self-reported.

Examples: How is Marital Status reported for the following situations?

1. Patient with multiple tumors in the database, for the first tumor marital status is reported as married (code 2), for the subsequent tumor, marital status is reported as single (code 1).

2. Patient self- reports as single, but also has children.

3. Patient states they are in common law marriage, but our state is not a common law marriage state.

Marital Status is self-reported because the information is recorded in the medical record based on information obtained from the patient. Use text fields to document relevant information.

Examples

1. Assign code 2 for the first tumor and assign code 1 for the subsequent tumor unless the available information indicates the patient is divorced at the time of the subsequent tumor diagnosis. Patient may self-report single after a divorce. Assign code 4 in that situation.

The code assigned for marital status reflects the patient's marital status at the time of diagnosis for the tumor being abstracted. It is possible that marital status may be different for each tumor if the patient has multiple tumors.

2. If marital status is stated to be single, assign code 1.

3. If marital status is stated to be common law marriage, assign code 2.

Common Law Marriage is defined as a couple living together for a period of time and declaring themselves as married to friends, family, and the community, having never gone through a formal ceremony or obtained a marriage license.

20031153 Laterality/Multiple Primaries (Pre-2007)--Ovary: Are ovarian primaries with bilateral involvement always coded to laterality 4 (bilateral)? See Description. Example: "Right ovary with mass replacing majority of ovarian tissue consistent with serous adenoca. Lt ovary with foci of adenoca." No specific statement of primary. Can we assume that the malignancy originated in the right ovary since it is more extensively involved or should laterality be coded 4 because both ovaries have tumor?

For tumors diagnosed prior to 2007:

If one ovary is listed as the primary site, code laterality to that ovary. The example above is one of those times when you would code to the single ovary. The issue of one or both ovaries being involved is handled in staging.

Abstract the example above as a single primary with code 1 [Right] for laterality.

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.
