Is Q52.4 (Other congenital malformations of female genitalia) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report other congenital malformations of vagina on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does Q52.4 group to?
When other congenital malformations 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 Q52.4 exempt from POA reporting?

Can Q52.4 be reported with a code from E34.5?
Not as a rule. The Excludes1 note at block Q50-Q56, which applies to Q52.4, 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).
