About coding Chorioadenoma
The ICD-10-CM code for Chorioadenoma is D39.2 (Neoplasm of uncertain behavior of placenta).
Within D39 (neoplasm of uncertain behavior of female genital organs), D39.2 is specifically for neoplasm of uncertain behavior of placenta. Related codes cover uterus (D39.0), ovary (D39.1), other specified female genital organs (D39.8) and female genital organ, unspecified (D39.9).
Don't report D39.2 together with the conditions in its Excludes1 note: hydatidiform mole NOS (O01.9).
