The ICD-10-CM code for female pseudohermaphroditism, not elsewhere classified is Q56.2 (sometimes written as Q562). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is Q56.2 (Indeterminate sex and pseudohermaphroditism) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report female pseudohermaphroditism, not elsewhere classified on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does Q56.2 group to?
When female pseudohermaphroditism, not elsewhere classified 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 Q56.2 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 female pseudohermaphroditism, not elsewhere classified on inpatient claims. The code appears in the Congenital malformations of genital organs (Q50-Q56) range of the CMS exempt list.
Can Q56.2 be reported with Q99.1?
Not as a rule. The Excludes1 note at Q56, which applies to Q56.2, lists "46,XX true hermaphrodite (Q99.1)". 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).
