Questions About Q67.6Overview

What is the ICD-10 code for pectus excavatum?

The ICD-10-CM code for pectus excavatum is Q67.6 (sometimes written as Q676). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Is Q67.6 a billable code?

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

What MS-DRG does Q67.6 group to?

When pectus excavatum 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 Q67.6 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 pectus excavatum 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 Q67.6 be reported with a code from Q87?

Not as a rule. The Excludes1 note at Q67, which applies to Q67.6, lists "congenital malformation syndromes classified to Q87.-". 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).
