First Course Treatment--Prostatic Urethra: Is Lupron coded for a papillary carcinoma of the prostatic urethra that is treated with a TUR with fulguration and beam radiation even though the prostate biopsies are negative?
Do not code lupron as treatment for a primary in the prostatic urethra.
Reportability/Histology--Pancreas: Is mucinous cystic neoplasm of pancreas reportable?
Non-invasive mucinous cystic neoplasm (MCN) of the pancreas with low or intermediate grade dysplasia is NOT reportable.
Non-invasive mucinous cystic neoplasm (MCN) of the pancreas with high grade dysplasia is reportable. For neoplasms of the pancreas, the term MCN with high grade dysplasia replaces the term mucinous cystadenocarcinoma, non-invasive.
CS Extension--Prostate: Does the term "activity" in a Prostascint report indicate a clinically apparent tumor, tumor extension or tumor involvement for this primary site? (http://www.rtrurology.com/prostascint.htm)
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.
No, the term "activity" alone does not indicate clinically apparent tumor or involvement.
Date of Diagnosis: How do you code this field when the pathologic confirmation is delayed for 2 months because the clinician decides to "watch and see what happens" to a CT identified mass thought to be either a "metastasis from a previously diagnosed malignancy or a new primary"?
Code the Date of Diagnosis field to the date of the scan. This is the earliest date that a recognized medical practitioner said the patient had cancer. The diagnosis on the CT scan was a malignancy. The only question was whether the mass on the scan was metastatic or a primary.
Histology (Pre-2007)--Breast: What code is used to represent the histology "ductal adenocarcinoma with medullary features?"
For tumors diagnosed prior to 2007:
Medullary is a subtype of duct and "with features of" is a term that indicates a majority of tumor. If this is an invasive adenocarcinoma with no in situ component, code to 8510/3 [Medullary adenocarcinoma]. If only one of the components is invasive, code that component.
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.
Reportability/Histology--Skin: Is 'skin, left temporal scalp, low grade adnexal carcinoma, probable sweat gland origin' reportable as 8400/3, skin of temple?
Assign 8390/3 for adnexal carcinoma of skin. 8390/3 is reportable, including 8390/3 of skin.
First Course Cancer-Directed Treatment--Bladder: How should Mitomycin-C instillation for bladder cancer be coded?
Code the instillation of Mitomycin-C into the bladder for a bladder primary in both the Chemotherapy and Surgery to Primary Site fields. Code the Chemotherapy field to 02 [Single-agent chemotherapy administered as first course therapy]. Mitomycin-C is listed in SEER book 8 as a chemotherapeutic drug, specifically an alkylating agent.
Also, code the Surgery of Primary Site field to 15 [intravesical therapy]. Code the surgical procedure as well as the type of drug (chemotherapy in this case).
2024 SEER Manual/Primary Site--Breast: Is Primary Site coded as C504 or C501 based on the Solid Tumor Rules and the SEER Manual Breast Coding Guidelines? The pathology report reads "Right Breast 10:00 1 cm from the nipple."
Codes C502-C505 take priority over code C501. The description for C501 in the Solid Tumor Rules has "Area extending 1 cm around areolar complex."
Assign Primary Site code C504 based on the location in the upper outer quadrant of the right breast, 10 o’clock, as opposed to code C501, around the areolar complex. The 2024 SEER Manual Breast Coding Guidelines advise that C502 - C505 are generally preferred over C501 when there is no other way to determine the subsite.
Primary Site: How is this field coded for cholangiocarcinoma involving the intrapancreatic bile duct?
Code the primary site as C24.0 [Extrahepatic bile duct, includes Common bile duct] for a cholagiocarcinoma originating in the common bile duct. A portion of the common bile duct is within the head of the pancreas: The intrapancreatic segment of the common bile duct.
Unless the disease is specified as primary, idiopathic, essential, or the physician states there is a myeloproliferative neoplasm, the term thrombocytosis, NOS is not reportable. Thrombocytosis, NOS, is the presence of high platelet counts in the blood. Thrombocytosis can be associated with chronic infections and other diseases as well as with myeloproliferative disease. Thrombocytosis, NOS is listed in Appendix F as a Non-Reportable Term.
