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.
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.
Histology (Pre-2007): What is the difference between code 8244/3 composite carcinoid (combined carcinoid and adenocarcinoma) and 8245/3 adenocarcinoid tumor?
For tumors diagnosed prior to 2007:
Assign code 8244/3 [composite carcinoid] when there is a combination of adenocarcinoma and carcinoid tumor.
Assign code 8245/3 [adenocarcinoid] when the diagnosis is exactly "adenocarcinoid."
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.
Surgery of Primary Site--Breast: How is this field coded when a patient has a reduction mammoplasty (for macromastia) and within the pathology specimen there is an incidental finding of carcinoma?
Code this reduction mammoplasty to the code which best fits the amount of tissue removed. Read the operative report carefully. Code as a partial mastectomy, skin- nipple- areola-sparing mastectomy, or total (simple) mastectomy. Use text fields to record the details.
CS Lymph Node Examined--Lung: How is this field coded when a mediastinoscopy and lobectomy are performed and the pathology report indicates multiple lymph node fragments were removed as biopsy specimens and the lobectomy specimen revealed 3 interlobar lymph nodes?
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.
Code the CS Lymph Node Examined field to 98 [number unknown] because the biopsy information is not clear and as a result you do not know how many lymph nodes were examined.
MP/H/Multiple primaries--Urinary: In Aug 2008 Patient was diagnosed with Noninvasive Bladder Cancer. In Oct 2013 Patient was diagnosed with Transitional Cell Carcinoma of Right Ureter involving lamina propria, Noninvasive Transitional Cell Carcinoma Left Ureter and Invasive Transitional Cell Carcinoma of Prostatic Urethra. Is this a new primary and what is the primary site?
Rule M7 applies when comparing the 2008 diagnosis to the 2013 diagnosis: multiple primaries.
Rule M8 applies to the tumors identified in 2013: single primary.
Based on the information provided, code the primary site for 2013 to C689 because there is no indication of the site of origin among the involved sites.
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).
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/Behavior--Brain and CNS: How should Histology and Behavior be coded for a polymorphous low-grade neuroepithelial tumor of the young (PLNTY) arising in the brain?
