Surgery of Primary Site--Ovary: What code is used to represent this field when a patient has a history of a previous organ removal and has additional surgery/organ removal for a present cancer (e.g., History of a 1984 hysterectomy and in 2003 has ovarian primary treated with BSO)?
For cases diagnosed 1/1/2003 and after: Code the Surgery of Primary Site field to 52 [Bilateral salpingo-oophorectomy WITH hysterectomy].
Surgery of Primary Site--Brain and CNS: Is "debulking" of a primary brain tumor coded to 21 [subtotal resection of tumor] or 30 [gross resection of tumor]?
Assign code 21 [subtotal resection of tumor, lesion, or mass]. Debulking removes as much of the tumor volume as possible in cases where it is not possible to remove the entire tumor. Debulking should improve the effectiveness of subsequent radiation therapy and/or chemotherapy.
VIN II-III is reportable based on ICD-O-3.2 which lists squamous intraepithelial neoplasia, grade II as 8077/2 making it reportable. Also see SINQ 20120094.
Multiple Primaries (Pre-2007)--Vulva/Vagina: SEER Program Code Manual rule #3 on page 11 states "If a new cancer of the same histology is diagnosed in the same site after two months, consider this new cancer a separate primary unless stated to be recurrent or metastatic. Should vulva and vagina be exceptions to rule #3, as are prostate and bladder?
For tumors diagnosed prior to 2007:
No. There is no exception for vulva or vagina.
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.
Multiple Primaries (Pre-2007)--Melanoma: Many melanoma patients have multiple occurrences over time that are not called recurrent and often are even in the same skin subsite, some in situ only and others alternating between in situ and invasive. Should these multiple occurrences really be new primaries?
For tumors diagnosed prior to 2007:
Unless it is stated to be a RECURRENT or METASTATIC melanoma, record each melanoma as a separate primary when:
1. The occurrences are more than two months apart.
2. The fourth digit of the ICD-O topography code for skin [C44._] is different .
3. The first three digits of ICD-O-3 morphology code are different.
4. An in situ melanoma is followed by an invasive melanoma.
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.
MP/H Rules/Multiple primaries -- Ovary: How many primaries are to be accessioned and what rule applies when a patient has a serous carcinoma of the right ovary treated with neoadjuvant chemotherapy followed by a debulking surgery that revealed a serous tubal intraepithelial carcinoma of the left fallopian tube?
For cases diagnosed 2007 or later, accession two primaries, serous carcinoma of the right ovary and serous tubal intraepithelial carcinoma of the left fallopian tube based on the information provided.
The steps used to arrive at this decision are:
Open the Multiple Primary and Histology Coding Rules Manual. Choose one of the three formats (i.e., flowchart, matrix or text) and go to the Other Sites MP rules because neither the ovary nor fallopian tube have site specific rules developed.
Start at the MULTIPLE TUMORS module, Rule M3. The rules are intended to be reviewed in consecutive order within a module. The patient has multiple tumors with ICD-O-3 topography codes that are different at the third character (Cxx) and therefore this case should be accessioned as a multiple primary.
It could be helpful to know the extent of involvement noted prior to neoadjuvant therapy and debulking surgery. For example, if the patient had widely metastatic disease throughout the entire pelvis prior to the initiation of treatment, the answer may have been different.
Histology (Pre-2007)--Breast: What code is used to represent the histology "infiltrating lobular carcinoma, solid and classical subtypes"?
For tumors diagnosed prior to 2007:
Code the Histology field to 8520 [Lobular carcinoma].
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.
Multiple Primaries (Pre-2007)--Testis: How many primaries should be reported when seminoma is diagnosed simultaneously in both testicles and both tumors are encapsulated?
For tumors diagnosed prior to 2007:
Report this cases as two primaries, unless there is information in the record confirming one primary.
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.
Multiple Primaries/Histology--Mycosis Fungoides/Cutaneous T cell Lymphoma: Physicians often use the terms cutaneous T cell lymphoma (CTCL) and mycosis fungoides interchangeably and yet the SEER Single versus Subsequent Primaries of Lymphatic and Hematopoietic Diseases table indicates that these 2 diagnoses represent separate primaries. Do these cases represent one primary? If so, what histologic type should they be coded to?
For cases diagnosed prior to 1/1/2010:The patient does not have two different malignancies. Code the Histology field to 9700/3 [mycosis fungoides], the specific type of cutaneous T cell lymphoma. Mycosis fungoides is one of several types of cutaneous T cell lymphoma. Physicians often refer to mycosis fungoides by the "umbrella term" cutaneous T cell lymphoma.
The table indicates that the broad category of "T/NK-cell NHL" (which includes CTCL) and mycosis fungoides are presumably separate primaries because several entities are included in that broad category. In the specific case cited above, one entity (CTCL) within the broad category (T/NK-cell NHL) and mycosis fungoides are not separate primaries.
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.
Final Dx for left Breast biopsy: Atypical epithelial proliferation (ADH/DCIS). Comment: Sections show small focus of atypical epithelial proliferation with features of atypical duct hyperplasia/low grade duct carcinoma in-situ.
ADH/DCIS is reportable. DCIS (duct carcinoma in situ) is a reportable neoplasm. When DCIS is stated as the final diagnosis, report the case.
