Questions About Q50.6Overview

Is Q50.6 a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report other congenital malformations of fallopian tube and broad ligament on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

What MS-DRG does Q50.6 group to?

When other congenital malformations of fallopian tube and broad ligament is the principal diagnosis on an inpatient stay, it groups to MS-DRG 742, 743, 760, 761, with relative weights from 0.5696 to 1.8348 depending on complications. Higher weights mean higher Medicare reimbursement.

Is Q50.6 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 other congenital malformations of fallopian tube and broad ligament on inpatient claims.

What is the ICD-9 equivalent of Q50.6?

Under the General Equivalence Mappings, other congenital malformations of fallopian tube and broad ligament converts to ICD-9-CM 752.10 (tubal/broad lig anom NOS) and 752.19 (tubal/broad lig anom NEC). The mapping is approximate, so confirm the match fits the documentation.
