Excludes2

Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.

Questions About Q74.9Overview

What is the ICD-10 code for unspecified congenital malformation of limb(s)?

The ICD-10-CM code for unspecified congenital malformation of limb(s) is Q74.9 (sometimes written as Q749). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Is Q74.9 (Other congenital malformations of limb(s)) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report unspecified congenital malformation of limb(s) on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What MS-DRG does Q74.9 group to?

When unspecified congenital malformation of limb(s) is the principal diagnosis on an inpatient stay, it groups to MS-DRG 564, 566, 565, with relative weights from 0.7374 to 1.4909 depending on complications. Higher weights mean higher Medicare reimbursement.

Is Q74.9 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 unspecified congenital malformation of limb(s) on inpatient claims. The code appears in the Congenital malformations and deformations of the musculoskeletal system (Q65-Q79) range of the CMS exempt list.

Can Q74.9 be reported with a code from Q69?

Not as a rule. The Excludes1 note at Q74, which applies to Q74.9, lists "polydactyly (Q69.-)". 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).
