Q51.2Other doubling of uterus

Q51.2 is the ICD-10-CM diagnosis code for other doubling of uterus. It belongs to category Q51 (congenital malformations of uterus and cervix), 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 4 subcodes must be used instead.

Within Q51, choose Q51.2 (Other doubling of uterus) only when documentation doesn't support a more specific option: agenesis and aplasia of uterus (Q51.0), doubling of uterus with doubling of cervix and vagina (Q51.1), Bicornate uterus (Q51.3), Unicornate uterus (Q51.4), agenesis and aplasia of cervix (Q51.5), Embryonic cyst of cervix (Q51.6), congenital fistulae between uterus and digestive and urinary tracts (Q51.7), other congenital malformations of uterus and cervix (Q51.8) and 1 more.

To report this condition, pick the subcode that matches the documentation: Q51.21 (uterus), Q51.22 (uterus) and Q51.28 (uterus).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2019 (expanded into subcodes).

Before ICD-10, this condition was coded in ICD-9-CM as 752.2 (doubling of uterus) and 752.35 (Septate uterus).
