Questions About Q15.0Overview

What is the ICD-10 code for congenital glaucoma?

The ICD-10-CM code for congenital glaucoma is Q15.0 (sometimes written as Q150). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Is Q15.0 (Other congenital malformations of eye) a billable code?

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

What MS-DRG does Q15.0 group to?

When congenital glaucoma is the principal diagnosis on an inpatient stay, it groups to MS-DRG 125, 124, with relative weights from 0.7699 to 1.2470 depending on complications. Higher weights mean higher Medicare reimbursement.

Is Q15.0 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 glaucoma on inpatient claims. The code appears in the Congenital malformations of eye, ear, face and neck (Q10-Q18) range of the CMS exempt list.

Can Q15.0 be reported with H55.01?

Not as a rule. The Excludes1 note at Q15, which applies to Q15.0, lists "congenital nystagmus (H55.01)". 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).
