Date Therapy Initiated: How would you estimate the date treatment began for a patient who was treated elsewhere and seen only on an outpatient basis at the current facility? See discussion.
July 19th: Retromolar trigone primary was diagnosed.
August 8th note states, "Pt is not a surgical candidate due to multiple medical co-morbidities." Sept 19th note states, "Per Tumor Board, pt has been undergoing radiation for her head and neck cancer." The exact starting date for radiation is not specified.
In the SEER Program Code Manual it states that "In the absence of an exact date of treatment, the date of admission for that hospitalization during which the first cancer directed therapy was begun is an acceptable entry."
If possible, review the radiation treatment summary and outpatient records at the treating facility. If the date treatment began is not stated, look for the completion date and number of treatments, and calculate the first date of treatment.
If the date radiation started cannot be found or calculated, code the month as 09 for the example provided. The determination was made in August NOT to treat with surgery. We know that there was treatment in September.
Date Therapy Initiated: What date should be entered in Date Therapy Initiated when treatment follows a surgical procedure that is not coded under Surgery of Primary Site? See discussion.
If a patient has a surgical procedure that is not coded in the Surgery of Primary Site field and then the patient undergoes additional first course of treatment, such as radiation therapy, how should the Date Therapy Initiated field be coded?
In this example, code the Date Therapy Initiated field to the date of the first surgical procedure. If a SEER edit is triggered, please notify us.
DCO/Multiplicity Counter/Type of Multiple Tumors: How are these fields coded for an unknown primary reported as a DCO case? See Discussion.
Do DCO cases have default values for the Multiplicity Counter and Multiple Tumor Reported as One Primary fields? Should these fields be coded as 88 or 99?
In the data item pages for these fields, there is only a reference to see the NAACCR Death Clearance Manual. However, this manual does not provide an answer. There is guidance to use code 88 for unknown primaries but we noticed that SEER edits skip enforcing this requirement for DCO cases (see SEER IF205 and 206).
For a DCO case reported as an unknown primary [C809], code Multiplicity Counter to 99 [Unknown if multiple tumors; not documented] and Type of Multiple Tumors Reported as One Primary to 99 [Unknown].
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].
Diagnostic confirmation--Heme & Lymphoid Neoplasms: What is the diagnostic confirmation code for a death certificate only (DCO) diagnosis of acute myeloid leukemia?
Always code diagnostic confirmation to 9 [Unknown whether or not microscopically confirmed; death certificate only] for DCO cases.
SEER*Educate provides training on how to use the Heme Manual and DB. If you are unsure how to arrive at the answer in this SINQ question, refer to SEER*Educate to practice coding hematopoietic and lymphoid neoplasms. Review the step-by-step instructions provided for each case scenario to learn how to use the application and manual to arrive at the answer provided. https://educate.fhcrc.org/LandingPage.aspx.
Diagnostic Confirmation--Leukemia: How is this field coded when the clinician confirms that the diagnosis of CML is based on a combination of the clinical picture and positive cytogenetic studies?
Assign code 1 [Positive histology]. For leukemia only, assign code 1 for positive hematologic findings including peripheral blood smears, CBCs and WBCs.
Cytogenetics studies would have been done on blood. Therefore, histology provided diagnostic confirmation as it would with smear, bone marrow, or other special study of blood cells.
Diagnostic Confirmation--Prostate: How do we code this field when there is an elevated PSA, no other work-up and there is a clinical diagnosis of adenocarcinoma?
Code the Diagnostic Confirmation field to 5 [positive laboratory test/marker study] to indicate the diagnosis is based upon an abnormal PSA tumor marker if the physician uses the PSA as a basis for diagnosing prostate cancer.
Diagnostic Confirmation--Testis: How do you code this field when a testicular mass is confirmed to be cancer on physical exam and testicular antigen, but the orchiectomy specimen was negative and yet the final signout diagnosis on the medical record was "testicular cancer"?
Code the Diagnostic Confirmation field to 5 [Positive laboratory test/marker study] because the disease was confirmed both clinically and by a positive marker. Code 8 [Clinical diagnosis only] is used when the diagnosis is based on information other than that coded in 5, 6, or 7 [positive lab test/marker study, visualization, and radiography or other imaging techniques]. Code 8 is rarely used.
