Questions About Q10.6Overview

Is Q10.6 a billable code?

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

What MS-DRG does Q10.6 group to?

When other congenital malformations of lacrimal apparatus is the principal diagnosis on an inpatient stay, it groups to MS-DRG 124, 125, with relative weights from 0.7678 to 1.3231 depending on complications. Higher weights mean higher Medicare reimbursement.

Is Q10.6 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 lacrimal apparatus on inpatient claims.

What is the ICD-9 equivalent of Q10.6?

Under the General Equivalence Mappings, other congenital malformations of lacrimal apparatus converts to ICD-9-CM 743.65 (spec lacrimal pass anom). The mapping is approximate, so confirm the match fits the documentation.
