Questions About Q27.31Overview

What is the ICD-10 code for arteriovenous malformation of vessel of upper limb?

The ICD-10-CM code for arteriovenous malformation of vessel of upper limb is Q27.31 (sometimes written as Q2731). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Is Q27.31 (Arteriovenous malformation (peripheral)) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report arteriovenous malformation of vessel of upper limb on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What MS-DRG does Q27.31 group to?

When arteriovenous malformation of vessel of upper limb is the principal diagnosis on an inpatient stay, it groups to MS-DRG 301, 300, 299, with relative weights from 0.7132 to 1.5840 depending on complications. Higher weights mean higher Medicare reimbursement.

Is Q27.31 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 arteriovenous malformation of vessel of upper limb on inpatient claims. The code appears in the Congenital malformations of the circulatory system (Q20-Q28) range of the CMS exempt list.

Can Q27.31 be reported with I77.0?

Not as a rule. The Excludes1 note at Q27.3, which applies to Q27.31, lists "acquired arteriovenous aneurysm (I77.0)". 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).
