Question:

Primary Site--Testis: What is the prmary site for a 38 y/o male diagnosed with testicular cancer in a formerly undescended testis that was treated with orchiopexy at age 10-11? See discussion.

Discussion:

Should it be coded to where the testis was physically at the time of diagnosis (C621), or should it be coded to C620 to reflect the increased risk for developing malignancy in an undescended testis?

Answer:

Code the primary site C621 (descended testis). The primary site of this neoplasm is a scrotal (descended) testis. The history of orchiopexy can be noted in a text field, but does not change the primary site in this case.
