About Q52.1
Q52.1 is the ICD-10-CM diagnosis code for doubling of vagina. It belongs to category Q52 (other congenital malformations of female genitalia), 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.

To report this condition, pick the subcode that matches the documentation: Q52.10 (unspecified), Q52.11 (septum) and Q52.12 (septum).
Don't report Q52.1 together with the conditions in its Excludes1 note: doubling of vagina with doubling of uterus and cervix (Q51.1-).
