MP/H Rules/Multiple primaries--Breast: Is this the same primary per MP/H Rule M10? Ductal carcinoma of the left breast in 2013, treated with a lumpectomy. New tumor with ductal and lobular carcinoma in the same breast in 2016.
The 2016 diagnosis is the same primary. MP/H Rule M10 for breast cancer applies. Do not change the original histology code. Use text fields to document the later histologic type -- duct and lobular.
Multiple Primaries (Pre-2007)--Kidney/Bladder/Renal Pelvis: Would transitional cell carcinoma of the left renal pelvis, diagnosed two years after a diagnosis of invasive bladder cancer, be a second primary when the discharge is "recurrent transitional cell carcinoma, left kidney"?
For tumors diagnosed prior to 2007:
This is an example of the term "recurrent" being used loosely to refer to another primary in the urinary tract. It is highly unlikely that a bladder tumor would metastasize to the kidney. Much more likely is the field defect or regional breakdown of the urothelial tissue that lines the tract from the renal pelvis to the urethra. Furthermore, bladder tumors don't spread retrograde to the kidney. Code as two primaries.
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/Behavior--Hematopoietic, NOS: Is a "myelodysplastic/myeloproliferative disease, unclassifiable" coded to 9975 with a behavior code of 3 as indicated in the WHO blue book on "Tumours of Haematopoietic and Lymphoid Tissues" or is it not abstracted because it has a behavior code of 1 which means the case is not reportable?
For cases diagnosed prior to 1/1/2010:Code MDS/MPD U to 9975/3 [Myelodysplastic/myeloproliferative disease, unclassifiable]. Change the behavior code to /3 according to ICD-O-3 Rule F. The case is reportable.
The WHO book is more recent and gives a specific code for this new hybrid category of the WHO/REAL classification.
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.
CS Lymph Nodes/Scope of Regional Lymph Node Surgery--Prostate: When prostate cancer is an incidental finding at cystoprostatectomy for bladder cancer, is the pelvic lymph node dissection coded for the prostate as well as the bladder?
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.
Yes, the pelvic lymph node dissection is coded as regional lymph node surgery for both primaries and the nodes are counted in collaborative staging for both primaries. The examination of the pelvic lymph nodes is relevant to both the bladder and the prostatic primaries.
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?
CS Extension: How is CS Ext coded for the following?
Rretroperitoneal primary
Cystic mucinous tumor with intraepithelial carcinoma
There is no CS Extension code for intraepithelial ca in the retroperitoneal scheme.
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.According to the American College of Surgeons I & R system, assign code 10 [confined to site of origin] for intraepithelial carcinoma of the retroperitoneum.
Date Multiple Tumors--Prostate: For a prostate biopsy done 10/20/08, both lobes involved with tumor, unknown how many tumors, what would be coded in date of multiple tumors?
In this case, code the date of the biopsy in Date of Multiple Tumors [10202008]. When the number of tumors is unknown, code the date of diagnosis as the Date of Multiple Tumors. This is the date on which it was determined that there were an unknown number of tumors. This instruction will be added to next edition of the MP/H manual.
Date of Diagnosis: If a clinician states his current diagnosis of malignancy is based on a CT scan done at an early date that contained a diagnosis of only "neoplasm" or "worrisome for carcinoma" should the date of diagnosis be the date of the scan?
Yes. Code the Date of Diagnosis field to the date of the scan. The physician's clinical impression upon reviewing the earlier scan, is that the malignancy was confirmed by the scan. If there is a medical review of a previous scan that indicates the patient had a malignancy at an earlier date, then the earlier date is the date of diagnosis, i.e., the date is back-dated.
Heme & Lymphoid Neoplasms: How is cancer status to be coded when a patient diagnosed with MDS, undergoes treatment, but the MDS subsequently transforms to AML?
If the bone marrow no longer shows evidence of MDS, the cancer status for the MDS is disease-free. When cancer status is coded as disease-free (NED), it means that currently there is no clinical evidence of this disease (MDS).
