Is P38 a billable ICD-10-CM code?

No. P38 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does P38 sit in the tabular list?

Certain conditions originating in the perinatal period (P00-P96), in the block Infections specific to the perinatal period (P35-P39).

What cannot be coded together with P38?

P38 carries an Excludes1 note, which means the conditions it lists can never be coded together with it on the same encounter.

P38 — Omphalitis of newborn

Non-billable headerICD-10-CM

P38 is a non-billable header ICD-10-CM code for omphalitis of newborn. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

omphalitis not of newborn (L08.82)
tetanus omphalitis (A33)
umbilical hemorrhage of newborn (P51.-)

Other codes that can never be billed with P38

These codes carry an Excludes1 note pointing at P38. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading P38 alone.

L08.82Omphalitis not of newborn
P51Umbilical hemorrhage of newborn
L02.2Cutaneous abscess, furuncle and carbuncle of trunk

Risk adjustment

P38 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 P38

2 child codes. Green means billable.
