20031032 | Diagnostic Confirmation--Hematopoietic, NOS: How should diagnostic confirmation of Hematopoietic diseases be coded in the absence of positive bone marrow? See Description. | Case 1. Patient admitted 9-12-02 with diagnosis of essential thrombocythemia. Per the H&P, patient obviously has had this since January 2001. Per the clinical history: patient with elevated platelets. Path diagnosis of bone marrow biopsy done 9-20-02 showed mildly increased megakaryocytes. 10-31-02 clinical sign-out diagnosis was: essential thrombocythemia. Case 2. Patient admitted for evaluation of erythrocytosis. Assessment: Increased hematocrit only. It is most likely that patient has polycythemia vera. I think it is reasonable to initiate phlebotomy treatment. |
Code 1, Positive histology, includes diagnostic hematologic findings and peripheral blood smears when these are the basis for diagnosis. When the clinician makes a specific diagnosis and the blood work is not diagnostic, code diagnostic confirmation as 8 [Clinical diagnosis only]. The clinician is putting together all evidence, including the blood work and using his/her professional experience to diagnose the case. Case 1. The diagnosis is not based on microscopic findings. Assign code 8 [Clinical diagnosis only]. Megakaryocytes are the immature form of thrombocytes, but mildly increased megakaryocytes are not diagnostic of essential thrombocythemia. Case 2. The diagnosis is not based on microscopic findings. Assign code 8 [Clinical diagnosis only]. |

20091055 | Date therapy initiated/Systemic/Surgery Sequence--Breast: How are these fields coded when a patient has chemotherapy after a sentinel lymph node biopsy and has a lumpectomy after completing chemotherapy? See Discussion. | On 4-10-08 a patient underwent sentinel lymph node biopsies. This was followed by chemotherapy which started on 4-15-08. The patient subsequently underwent a lumpectomy on 11-10-2008. | For this case, code Date Therapy Initiated to the date of the sentinel lymph node biopsy [04102008]. Assign code 3 [Systemic therapy after surgery] in Systemic/Surgery Sequence. |

20110058 | Date of diagnosis/Flag: Will the Date of Diagnosis Flag ever be used if the instructions for coding Date of Diagnosis are followed? See Discussion. | If an abstractor follows the instructions for coding the Date of Diagnosis and can at least estimate a year of diagnosis, in what scenario will the Flag be used?
Per the 2010 SEER Manual,
Page 49 Date of Diagnosis, second paragraph, "Regardless of the format, at least Year of diagnosis must be known or estimated. Year of diagnosis cannot be blank or unknown." The manual gives the following guidelines for coding diagnosis date/flag:
Page 50, Coding Instructions: 3. If no information about the date of diagnosis is available a. Use the date of admission as the date of diagnosis b. In the absence of an admission date, code the date of first treatment as the date of diagnosis.
Page 51, Coding Instructions: 9. Estimate the date of diagnosis if an exact date is not available. Use all information available to calculate the month and year of diagnosis.
Page 53, Date of Diagnosis Flag, Coding Instructions: Always leave blank. Date of Diagnosis will always be a full or partial date recorded. |
The date of diagnosis flag should always be blank. | 2011 |
|
20130219 | Date of diagnosis/Ambiguous terminology--Breast: Can a mammogram BIRADS 4 or 5 assessment be used to assess reportability and can the date of the mammogram be used to code the date of diagnosis? See Discussion. |
Can the BIRADS number be used to assess reportability? Can a BIRADS assessment of "suspicious" be used to code the date of diagnosis? |
BIRADS category 4 and category 5 mammograms are not to be interpreted as a reportable "malignancy" for cancer registry purposes nor are they to be used to code the date of diagnosis should the patient subsequently have a malignancy confirmed. | 2013 |
|
20130168 | Date of diagnosis--Heme and Lymphoid Neoplasms: Is the date of diagnosis coded to the date a bone marrow biopsy revealed "plasma cell neoplasm; plasma cells are < 10%" or the date a diagnosis of myeloma was noted in the Discharge Summary? See Discussion. | Bone marrow biopsy pathology states: Plasma Cell Neoplasm. The plasma cells are < 10%.
Subsequent to the bone marrow biopsy, the Discharge Summary indicated the patient has a diagnosis of myeloma, hypercalcemia and negative bone marrow surveys.
What date is used for the date of diagnosis? |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Use the date of the Discharge Summary as the date of diagnosis. In this case, the date of diagnosis is the date the physician confirmed the diagnosis of myeloma using all information available.

20130047 | Date of diagnosis--Heme & Lymphoid Neoplasms: What is the diagnosis date for a patient with a mild thrombocytosis diagnosed in 2008, that was subsequently treated with Anagrelide in 11/2010 following an increase in platelet count, and later in 3/2011 was found to have positive JAK2 study physician refers to as essential thrombocythemia? See Discussion. | In 2008, patient diagnosed with mild thrombocytosis. The patient opted to be followed clinically with observation. In November 2010, a CBC showed an increased platelet count to 600,000. Anagrelide was started. The patient would never agree to a bone marrow biopsy. However, in 3/2011 a JAK2 study was performed and read as positive. Following the positive Jak2 study, physician stated the diagnosis was essential thrombocytosis and started the patient on a different drug. | Code the diagnosis date to 3/2011. It wasn't until 3/2011 that the physician documented a reportable diagnosis of essential thrombocytosis [9962/3].
Mild thrombocytosis is not reportable. Therefore, the case was not reportable in 2008. Although the patient was treated in 2010, there was no documentation of a reportable diagnosis. |

20130062 | Date of diagnosis--Heme & Lymphoid Neoplasms: Should the diagnosis date be coded to the date of the flow cytometry on the peripheral blood or the date of the bone marrow biopsy for a diagnosis of chronic lymphocytic leukemia/low grade B-cell lymphoma? See Discussion. | Is a flow cytometry on peripheral blood alone diagnostic of a hematopoietic malignancy (CLL)? If not, when the diagnosis is verified by a subsequent histologic diagnosis (bone marrow biopsy) would the diagnosis date be the date of the peripheral blood flow cytometry or the date of the bone marrow biopsy? The Class of Case depends on this diagnosis date. | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Code the diagnosis date to the date of the peripheral blood flow cytometry because this is a procedure used to diagnose CLL. Per both the Abstractor Notes and the Definitive Diagnostic Methods sections in the Heme DB, CLL is diagnosed by flow cytometry (immunophenotyping).

20100012 | Date of diagnosis--Breast: How is the date of diagnosis coded when a mammogram describes only "suspicious calcifications" with a BIRADS category of 4 assigned and the suspicious calcifications are subsequently proven to be malignant on biopsy? See Discussion. | The date of diagnosis is the date when cancer was first diagnosed by a recognized medical practitioner, whether clinically or microscopically confirmed. Ambiguous terminology used to determine reportability is listed in part I of FORDS pages 3-4. No BIRADS categories are included and, therefore, should not be used by the registrar to determine the earliest date of diagnosis. In addition, the term "suspicious for calcification" is not reportable, because calcification is benign condition, unless the physician describes it as malignant. Reference 46637, 12/29/2009 FORDS - In the last paragraph there is a statement that no BIRAD categories are listed...cannot be used to determine earliest date of diagnosis. Does the SEER Program follow this guideline? | The date of diagnosis for this case is the date of the biopsy. There is no reportable diagnosis on the mammogram. | 2010 |
|
20091050 | Date of Multiple Tumors--Breast: How is this field coded when a second breast tumor is found at mastectomy two months after the original breast cancer was diagnosed, but during initial workup and treatment? See Discussion. | Breast cancer was diagnosed on core biopsy on 02-27-07. It was not known that the breast was harboring 2 tumors until mastectomy was done on 4-01-07. Both tumors are counted as one primary. | Code "Date of Multiple Tumors" field to the date of the mastectomy. That is the date that multiple tumors were discovered. | 2009 |
|
20031063 | Date of Diagnosis: When the clinical information on a scan indicates a history of cancer, how do you code the month and/or year of diagnosis given these terms: "early in year," "late in year," "2-3 months ago," "7 months ago," "new diagnosis." See Description. | Case 1. Diagnosed with CLL in late 1996. Assumptions: Code the term "late" in the year to December. Date of diagnosis would be coded to December 1996.
Case 2. Diagnosed with CLL in early 1997. Assumptions: Code the term "early" in the year to January. Date of diagnosis would be coded to January 1997.
Case 3. Admitted July 2000. Per H & P, patient was diagnosed with prostate cancer 2-3 years ago. Assumptions: Select the higher number in the range (in this case 3 years) and subtract 3 years from date of admit to calculate year of diagnosis. Code diagnosis month to the month patient was admitted. Diagnosis date would be coded July 1997.
Case 4. Admitted in October 2001. H&P states that colon cancer was diagnosed 7 months ago. Assumptions: Subtract 7 months from date of admit. Code date of diagnosis to March 2001.
Case 5. Admitted in December 2001. Per H&P, patient has CLL, presumably a new diagnosis. Assumptions: Assume the H&P statement of "new" to be equivalent to "recent" and code date of diagnosis to date patient was admitted. In this case, date of diagnosis would be coded to December 2001.
Case 6. Admitted for radical prostatectomy for prostate cancer in March 2001. H&P states that his PSA was 5 in November 2000 and in January 2001, PSA was 5.3. Biopsies showed adenocarcinoma. Assumptions: Assume the biopsy was done the same month as the January 2001 increased PSA. Date of diagnosis would be coded to January 2001.
Case 7. Outpatient bone scan done December 2001. Clinical history on the scan stated patient has history of prostate cancer. The physician was queried about date of diagnosis. Per the physician response, patient was diagnosed in 2001. Assumptions: Assume the bone scan was part of the initial work-up for prostate cancer and estimate the date of diagnosis to December 2001. |
SEER agrees that these are reasonable assumptions based on the information provided.
Estimate the month and year of diagnosis using the available information. If the information is not sufficient to make an estimation on the month, code the month of diagnosis as "99." Avoid coding "unknown" for the year of diagnosis. |
