EOD-Extension--Corpus Uteri: How do you code myometrial involvement described as 1) "to the level of the middle one-third" or 2) "superficial"?
For cases diagnosed 1998-2003:
Evaluate each case carefully.
1. Code the EOD-Extension field to 12 [Myometrium-inner half] because the pathology report indicates involvement of the myometrium "to the level of." However, if you feel that you cannot make that determination with certainty and you cannot ask a pathologist for clarification, then code the EOD-Extension field to 14 [Myometrium, NOS].
2. Code the EOD-Extension field to 12 [Myometrium-inner half] for cases with "superficial" myometrial invasion.
First Course Treatment: What code is used to represent each treatment modality field when there is no indication that a particular modality of treatment was recommended or started?
Code the individual treatment fields to 0 or 00 [None] when the modality is not addressed in the treatment plan (or when a treatment plan is lacking) and there is no indication that a particular modality of treatment was recommended or started.
MP/H Rules/Histology--Brain and CNS: What is the histology code for a tumor originating in the cerebellum and extending into the fourth venrticle described as a glioblastoma with primitive neuroectodermal tumor component (WHO Grade IV)?
The WHO Classification of CNS tumours lists glioblastoma with primitive neuroectodermal tumor component as a subtype of glioblastoma and assigns 9440/3. Also referred to as glioblastoma with a primitive neuronal component.
Primary site--Lung: What is the code for primary site if a small cell carcinoma presents as mediastinal masses?
Code the primary site to main bronchus [C340].
Primary small cell carcinoma in the thymus/mediastinum is rare. A bronchial lesion with extension into the mediastinum is much more likely. In a case like this, it is difficult to be sure exactly where the tumor arose, however, it is recommended the default site be the main bronchus when there is no information to the contrary.
Reportability--Pancreas: Is a solid pseudopapillary neoplasm of the pancreas reportable?
Solid pseudopapillary neoplasm of the pancreas is reportable. According to the WHO classification, it is a "low-grade malignant neoplasm…[which] frequently undergoes hemorrhagic-cystic degeneration and occurs predominantly in young women."
Assign topography code C25 with the appropriate 4th digit. Code the histology as 8452/3.
Multiplicity Counter--Breast: How should the multiplicity counter be coded for a 3.8 cm infiltrating duct carcinoma with two "satellite nodules" measuring 5 mm and 7mm that are not described as either metastases or multiple foci?
Include these nodules in the multiplicity counter because they are measured and are part of the final diagnosis on the pathology report.
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--Heme & Lymphoid Neoplasms: How is histology to be coded for acute lymphoblastic leukemia (ALL) and/or precursor B acute lymphoblastic leukemia (Pre-B ALL) for cases diagnosed 2010 and later? The Heme Database has two histology codes for this disease, both 9811/3 and 9836/3, which is the correct histology code?
Code histology to 9811/3 [B lymphoblastic leukemia/lymphoma, NOS].
See the Abstractor Notes section in the Heme DB, when determining how to code histology for a case. It indicates the code 9811/3 is effective for cases diagnosed 2010 and forward. The 9836/3 is listed as obsolete and refers you to code 9811/3. Make sure to check for a specific subtype of B lymphoblastic leukemia/lymphoma [9812/3 - 9818/3] before assigning the NOS code [9811/3].

EOD-Clinical Extension--Prostate: Must all three criteria be met (an elevated PSA; documentation that the physical exam was negative; and, if a TRUS was done, there is documentation that the findings were negative) in order to code this field to 15 [Tumor identified by needle by elevated PSA]?
For cases diagnosed 1998-2003:
Refer to the Prostate EOD Coding Guidelines, Final version distributed to SEER Registries 6/20/2001.
Prostate clinical EOD extension code 15 is used when all three criteria are met as listed on page 3 of the Prostate EOD Coding Guidelines. Meeting 1 or 2 of the 3 criteria is not sufficient for code 15. PE must be done and documented as negative. TRUS may or may not be done, but if done, must be documented as negative. PSA must either be elevated or there is no documentation about the PSA.
Codes 20 and 23-24 would be used with positive physical exam or positive TRUS.
Use codes 30-34 when there is no documentation that the physical exam was negative, or no documentation that the TRUS was negative, or when the prostatic apex is involved.
Histology (Pre-2007)--Stomach: What code is used to represent the histology of "mucin-secreting adenocarcinoma, intestinal type "for a stomach primary?
For tumors diagnosed prior to 2007:
For this specific example, code histology to 8481 [Mucin-producing adenocarcinoma] as it is a more specific cell type with inherent prognostic information.
Code 8255/3 [Adenocarcinoma with mixed subtypes] is not appropriate for this case because "intestinal type" is a more specific description of this cancer and not another type of cancer. There are two broad categories of gastrointestinal adenocarcinomas: Intestinal and Diffuse.
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.
