Questions About P00.2Overview

What is the ICD-10 code for newborn affected by maternal infectious and parasitic diseases?

The ICD-10-CM code for newborn affected by maternal infectious and parasitic diseases is P00.2 (sometimes written as P002). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Is P00.2 a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report newborn affected by maternal infectious and parasitic diseases on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What MS-DRG does P00.2 group to?

When newborn affected by maternal infectious and parasitic diseases is the principal diagnosis on an inpatient stay, it groups to MS-DRG 951, 795, with relative weights from 0.2022 to 0.5574 depending on complications. Higher weights mean higher Medicare reimbursement.

Is P00.2 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 newborn affected by maternal infectious and parasitic diseases on inpatient claims. The code appears in the Newborn affected by maternal factors and by complications of pregnancy, labor, and delivery (P00-P04) range of the CMS exempt list.

Can P00.2 be reported with P00.8?

Not as a rule. The Excludes1 note on P00.2 lists "maternal genital tract or other localized infections (P00.8)". 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).
