P00 — Newborn affected by maternal conditions that may be unrelated to present pregnancy
P00 is a non-billable header ICD-10-CM code for newborn affected by maternal conditions that may be unrelated to present pregnancy. It cannot be billed on its own: choose one of the more specific child codes below.
Excludes2 — not included here, but may coexist
The excluded condition is not part of this code, but a patient can have both. You may code both.
- encounter for observation of newborn for suspected diseases and conditions ruled out (Z05.-)
- newborn affected by maternal complications of pregnancy (P01.-)
- newborn affected by maternal endocrine and metabolic disorders (P70-P74)
- newborn affected by noxious substances transmitted via placenta or breast milk (P04.-)
Code first
The underlying condition must be sequenced before this code.
- any current condition in newborn
Other codes that can never be billed with P00
These codes carry an Excludes1 note pointing at P00. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading P00 alone.
- P00.2Newborn affected by maternal infectious and parasitic diseases
Risk adjustment
P00 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
Code to one of these instead P00
