Questions About Q82.1Overview

What is the ICD-10 code for xeroderma pigmentosum?

The ICD-10-CM code for xeroderma pigmentosum is Q82.1 (sometimes written as Q821). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Is Q82.1 (Other congenital malformations of skin) a billable code?

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

What MS-DRG does Q82.1 group to?

When xeroderma pigmentosum is the principal diagnosis on an inpatient stay, it groups to MS-DRG 795, 607, 606, with relative weights from 0.2022 to 1.5721 depending on complications. Higher weights mean higher Medicare reimbursement.

Is Q82.1 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 xeroderma pigmentosum on inpatient claims. The code appears in the Other congenital malformations (Q80-Q89) range of the CMS exempt list.

Can Q82.1 be reported with E83.2?

Not as a rule. The Excludes1 note at Q82, which applies to Q82.1, lists "acrodermatitis enteropathica (E83.2)". 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).
