Q50.3Other congenital malformations of ovary

Q50.3 is the ICD-10-CM diagnosis code for other congenital malformations of ovary. It belongs to category Q50 (congenital malformations of ovaries, fallopian tubes and broad ligaments), block Q50-Q56 (congenital malformations of genital organs) and chapter 17 (congenital malformations, deformations, chromosomal abnormalities, and genetic disorders). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

Within Q50, choose Q50.3 (Other congenital malformations of ovary) only when documentation doesn't support a more specific option: congenital absence of ovary (Q50.0), developmental ovarian cyst (Q50.1), congenital torsion of ovary (Q50.2), Embryonic cyst of fallopian tube (Q50.4), Embryonic cyst of broad ligament (Q50.5) and other congenital malformations of fallopian tube and broad ligament (Q50.6).

To report this condition, pick the subcode that matches the documentation: Q50.31 (ovary), Q50.32 (streak) and Q50.39 (ovary).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
