Surgery of Primary Site--Corpus uteri: What is the correct surgery code to assign for dilation and curettage (D&C) for an in-situ endometrium (C541) primary? The code to use for the cervix uteri (C530-C539) is specified, but not for the corpus uteri (C540-C549).
Assign code 20 for endometrial D&C for in situ cancer of endometrium.
Multiple Primaries--Urinary: How many primaries should be coded for an 8/9/07 invasive transitional cell carcinoma of right ureter; 7/9/08 non-invasive urothelial carcinoma of bladder; 11/18/08 non-invasive urothelial carcinoma of left ureter; 6/20/09 invasive urothelial carcinoma of left ureter?
One primary. This is a good example of how the field effect occurs in the urinary system. From 2007 to 2008, Rule M8 says bladder and ureter tumors are not new primaries and would be documented as recurrences. Because other urinary sites are involved by 11/08 and by 06/09, do not make second primary of left ureter (Rule M4 does not apply).
Histology--Pancreas: How is a "gastrin and somatostatin producing endocrine neoplasm" coded that has lymph node metastasis?
The best code available for this situation is 8153/3 [Gastrinoma, malignant].
Many pancreatic endocrine tumors produce more than one peptide, such as gastrin and somatostatin in this case. ICD-O-3 does not provide a code for pancreatic endocrine tumors which produce more than one peptide. According to the WHO Classification of Tumours of Endocrine Organs, there is a distinct hormonal syndrome associated with gastrin producing tumors, and not with many of the somatostatin producing tumors. Therefore, our pathologist consultant advises us to code to gastrinoma in this case.
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.
MP/H Rules/Histology--Thyroid: Is a "papillary carcinoma of the thyroid" coded to 8260/3 [Papillary adenocarcinoma] per the ICD-O-3 because it lists "papillary carcinoma of the thyroid" as a synonym for that code or should it be coded to 8050 [Papillary carcinoma, NOS]?
For cases diagnosed 2007 or later, assign code 8260 [papilary carcinoma of the thyroid].
Histology--Hematopoietic, NOS: How is an "advanced MDS (RAEB-T)/emerging AML" coded when discovered on a bone marrow biopsy?
For cases diagnosed prior to 1/1/2010:Code histology to 9984/3 [RAEB-T]. This particular MDS is refractory anemia with excess blasts in transformation. It has not yet progressed to acute myeloid leukemia.
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.
Solid Tumor Rules (2018)/Histology--Lung: The Histology coding guidelines for lung cancer state to code histology when stated as type or subtype but not to code when described as pattern. How should the histology be coded (Adeno, NOS or Adeno, Mixed subtypes) if the College of Americal Pathologists Protocol of the pathology report lists the following: Histologic type: Adenocarcinoma, papillary (90%), lepidic (8%), and solid (2%) patterns?
The term/modifier "patterns" is no longer allowed to code a specific histology according to the Lung Solid Tumor H rules. Disregard the papillary, lepidic, and solid patterns and code histology to adenocarcinoma, NOS (8140/3).
Surgery of Primary Site--Bladder: Should a TURB be coded to 27 [Excisional biopsy; SEER Note: Code TURB as 27] when there is obvious extravesicular extension demonstrated because the 2004 SEER Manual states "Do not code an excisional biopsy when there is macroscopic residual disease"?
Assign code 27 [excisional biopsy]. The site-specific instructions have priority over the general instructions. According to the instructions for coding surgery of the bladder, use code 27 for TURB.
Multiplicity Counter--Ill-defined sites: How is this field coded for Ill-Defined sites (C760-C768)?
Code the number of tumors present if known. If the number of tumors present is not known, code 99 [unknown number of tumors, unknown if multiple tumors].
Multiple primaries--Heme & Lymphoid Neoplasms: Is a new bone marrow diagnosis of acute myelogenous leukemia that follows a 2007 treated diagnosis of a JAK-2 positive polycythemia vera a new primary?
Per Rule M10, abstract two primaries. Per the Heme DB, polycythemia vera [9950/3] transforms to an acute myelogenous leukemia [9861/3]. According to Rule M10, one is to abstract multiple primaries when a neoplasm is originally diagnosed as a chronic neoplasm (e.g., polycythemia vera) AND there is a second diagnosis of an acute neoplasm (e.g., acute myelogenous leukemia) more than 21 days after the chronic diagnosis.
