For cases diagnosed between 1998-2003:

Code the EOD-Extension field to 06 [sessile (flat) (solid) carcinoma in situ], the higher extension code.

For cases diagnosed prior to 1/1/2010:

Plasma cell dyscrasia, NOS, is nonreportable. It is not a synonym for multiple myeloma. Plasma cell dyscrasia represents a broad spectrum of disease characterized by plasma cell proliferation that appears inappropriate or uncontrolled. Multiple myeloma is one disease type that falls into that classification. However, there are several other malignant and benign diseases also classified as such because of their immunoglobulin abnormalities. Reportability to SEER regarding a disease classified as a plasma cell dyscrasia is dependent on identifying the specific cell type associated with the disease in the ICD-O-3.

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.

Cytology reported as "suspicious" is not reportable. If the physician confirms the suspicious cytology by making a clinical diagnosis of malignancy, the Date of Diagnosis field is coded to the date of the clinical diagnosis, which may or may not be same date the cytology was performed.

Without supporting clinical documentation, the case will remain non-reportable and will not be submitted to SEER. The supporting documentation can be a physician's statement that the patient has cancer, a scan or procedure that identifies cancer, or a positive biopsy.

Suspicious "biopsies" are reportable according to SEER's list of ambiguous terms. Suspicious "cytologies" without supporting clinical statements are not.

For tumors diagnosed prior to 2007:

Code the Histology field to 8480/3 [mucinous adenocarcinoma] using rule D in the Coding Complex Morphology Diagnoses: "Code the morphology with the highest code."

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.

For cases diagnosed prior to 1/1/2010:

Code the Grade, Differentiation field to 1 [Grade 1] for both of these cases because there is no mention of T-cell, B-cell, null cell, or NK cell involvement. Both cases have a pathologic description of well differentiated, not the descriptors "high grade," "low grade," or "intermediate grade" which must be ignored when coding grade for lymphomas.

For lymphomas, you cannot code the descriptions "high grade," "low grade," and "intermediate grade" in the Grade, Differentiation field because these terms refer to categories in the Working Formulation and not to histologic grade. However, you can code terms such as "well differentiated", "moderately differentiated" and "poorly differentiated" for lymphoma histologies.

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.

For cases diagnosed 1998-2003:

No, code the Date of Diagnosis field to the later biopsy date. Note 7 is intended for use in coding the EOD-Extension field, not the Date of Diagnosis field. The earlier scan has a diagnosis of RUL "mass" not a "malignancy" so the fact that there is mediastinal lymphadenopathy mentioned in that scan is not used to help determine date of diagnosis.

The case is reportable because the physician documented a clinical diagnosis of malignant melanoma. Code the Diagnostic Confirmation field to 8 [Clinical diagnosis only (other than 5, 6 or 7)].

Myelodysplastic syndrome cases with unknown dates of diagnosis identified in pre-2001 casefinding documents should not be accessioned and are not SEER reportable.

For cases identified in 2001 casefinding documents, when the diagnosis date cannot be confirmed using the medical records typically accessed by the registrar or central registry staff, do not accession these cases; they are not SEER reportable. This default applies only to those cases identified in 2001 casefinding documents.

For cases identified in 2002 or later casefinding documents, the attending physician should be contacted and asked to clarify the diagnosis date for cases identified with unknown dates of diagnosis. Clarifying the diagnosis date is necessary to determine whether the case is reportable and whether it should be accessioned.

For cases diagnosed 1998-2003:

You need path confirmation that a malignancy exists in the prostate before you can code the size of the nodule seen clinically.

Example 1: Code the EOD-Size of Primary Tumor to 010 [1 cm], because the nodule in the prostate is confirmed as cancer by needle biopsy.

Example 2: Code the EOD-Size of Primary Tumor to 999 because there was no pathologic confirmation of malignancy.

There are two primaries. For cases diagnosed 1/1/2003 and after: For the rt breast, code Surgery of Primary Site to 51. The contralateral left breast malignancy is not involved with the right breast primary by either direct extension or metastasis. Codes 42 and 52 are used to capture prophylactic mastectomy of the opposite noncancerous breast. In this case, the opposite breast has cancer so these codes cannot be used. Code Scope of Regional Lymph Node Surgery to 5 and Surgical Procedure of Other Site to 0.

For the lt breast, code Surgery of Primary Site to 41, Scope of Reg LN Surgery to 0, and Surgical Procedure of Other Site to 0.
