Question:
MP/H Rules/Histology--Testis: Which MP/H rule applies in coding the histology described as a "malignant mixed germ cell tumor with the following features: Histologic type: embryonal carcinoma (97%) and yolk sac tumor (3%)"? See Discussion.
Discussion:
Per MP/H rule H16, code the appropriate combination/mixed code (Table 2) when there are multiple specific histologies or when there is a non-specific histology with multiple specific histologies. The combination embryonal carcinoma and yolk sac tumor is not listed in Table 2, even though the pathology report indicates this is a mixed germ cell tumor.
Should rule H17 be applied and the numerically higher histology code be used?
Answer:
As of 2016: Code histology to 9085/3 [mixed germ cell tumor]. Combine 9065 and 9085 for analysis purposes.
History:
Prior to 2016
Code histology to 9065/3 [germ cell tumor, nonseminomatous]. Our pathologist consultant's comments for this code: Code 9065 is listed by ICD-O as germ cell tumor, nonseminomatous. This is a generic code for any germ cell tumor not containing seminoma.
