Questions About Q30.8Overview

What is the ICD-10 code for other congenital malformations of nose?

The ICD-10-CM code for other congenital malformations of nose is Q30.8 (sometimes written as Q308). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Is Q30.8 (Congenital malformations of nose) a billable code?

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

What MS-DRG does Q30.8 group to?

When other congenital malformations of nose is the principal diagnosis on an inpatient stay, it groups to MS-DRG 156, 155, 154, with relative weights from 0.6656 to 1.5916 depending on complications. Higher weights mean higher Medicare reimbursement.

Is Q30.8 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 nose on inpatient claims. The code appears in the Congenital malformations of the respiratory system (Q30-Q34) range of the CMS exempt list.

Can Q30.8 be reported with Q67.4?

Not as a rule. The Excludes1 note at Q30, which applies to Q30.8, lists "congenital deviation of nasal septum (Q67.4)". 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).
