Patient EducationClinical

Infant and Newborn Care

Going home with a new baby is exciting, but it can be scary, too. Newborns have many needs, like frequent feedings and diaper changes. Babies can have health issues that are different from older children and adults, like diaper rash and cradle cap.

Questions About P00Overview

Is P00 a billable code?

No. This is a category header that groups the codes for newborn affected by maternal conditions that may be unrelated to present pregnancy, and headers cannot be submitted on claims. Claims for newborn affected by maternal conditions that may be unrelated to present pregnancy need a more specific code from this category, such as P00.0, P00.1, and P00.2.

What is coded first with P00?

The Code First note reads: any current condition in newborn. When one of these applies, it is sequenced before P00.
