Questions About Q52.0Overview

What is the ICD-10 code for congenital absence of vagina?

The ICD-10-CM code for congenital absence of vagina is Q52.0 (sometimes written as Q520). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Is Q52.0 (Other congenital malformations of female genitalia) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report congenital absence of vagina on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What MS-DRG does Q52.0 group to?

When congenital absence of vagina is the principal diagnosis on an inpatient stay, it groups to MS-DRG 742, 743, 760, 761, with relative weights from 0.7039 to 1.8448 depending on complications. Higher weights mean higher Medicare reimbursement.

Is Q52.0 exempt from POA reporting?

Yes. CMS lists this code among those exempt from present on admission reporting, so hospitals do not assign a POA indicator for congenital absence of vagina on inpatient claims. The code appears in the Congenital malformations of genital organs (Q50-Q56) range of the CMS exempt list.

Can Q52.0 be reported with a code from E34.5?

Not as a rule. The Excludes1 note at block Q50-Q56, which applies to Q52.0, lists "androgen insensitivity syndrome (E34.5-)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
