Read the first 7 Abstracting & Coding flashcards as text

  1. Which of the following scenarios requires a new primary to be abstracted under the 2023 SEER MP/H rules for colon cancers?

    Answer: Different histology, same subsite, diagnosed 5 years apart

    Under MP/H rules, different histologies in the colon regardless of subsite and timing generally constitute separate primaries.

  2. What is the purpose of the 'date of diagnosis' field in a cancer abstract?

    Answer: The date of the first positive tissue diagnosis confirming malignancy

    The date of diagnosis is the date of the first histologic or cytologic confirmation of malignancy, not symptom onset or treatment date.

  3. When coding extent of disease for a breast cancer case, what does 'lymphovascular invasion (LVI) present' affect?

    Answer: Prognostic stage grouping

    LVI presence is a prognostic factor that can influence the overall prognostic stage group in AJCC breast cancer staging.

  4. A patient with CML (chronic myelogenous leukemia) is diagnosed via bone marrow biopsy. Which topography code is correct?

    Answer: C42.1 (bone marrow)

    CML originates in the bone marrow, so C42.1 is the correct primary topography code for this disease.

  5. Which coding rule applies when a physician documents a diagnosis using the words 'consistent with' or 'compatible with' malignancy?

    Answer: Abstract the case using those terms as diagnostic confirmation

    SEER and CoC guidelines specify that terms such as 'consistent with' and 'compatible with' are sufficient to abstract a case as malignant.

  6. What is the correct approach when a tumor's histology is described only as 'carcinoma' with no further specification?

    Answer: Code 8010/3 (Carcinoma, NOS)

    When a tumor is described only as 'carcinoma' without further specification, ICD-O-3 code 8010/3 (Carcinoma, NOS) is assigned.

  7. In the context of cancer registry abstracting, what does 'reportability' mean?

    Answer: Whether the diagnosis meets criteria for inclusion in the registry

    Reportability refers to whether a diagnosed condition meets the inclusion criteria for abstraction into the cancer registry.
