Question:

Reportability/Behavior: Is a "minimally invasive thymoma" a reportable malignancy if the pathology report does not specifically state it is malignant? See Discussion.

Discussion:

For example, are Types A, B1, B2 and B3 reportable if the pathology report does not state the tumor is a "Malignant Thymoma"?

Answer:

For cases diagnosed prior to 2021

According to our expert pathologist consultant, code using the terms in the pathology report. Do not try to second guess the pathologist.

Thymomas are /1 and not reportable unless the pathologist states "malignant". This includes A, AB, B1, B2, and B3. Any one of these types of tumors may exhibit invasion but do not code /3 based only on invasion.

Code thymoma as /3 if specifically designated "malignant" by the pathologist.

Thymic carcinoma and any of its subtypes are malignant, /3.
