Questions About Q11.2Overview
What is the ICD-10 code for microphthalmos?
The ICD-10-CM code for microphthalmos is Q11.2 (sometimes written as Q112). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is Q11.2 (Anophthalmos, microphthalmos and macrophthalmos) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report microphthalmos on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does Q11.2 group to?
When microphthalmos 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 Q11.2 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 microphthalmos 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 Q11.2 be reported with Q87.0?
Not as a rule. The Excludes1 note on Q11.2 lists "cryptophthalmos syndrome (Q87.0)". 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).
