P39.4

P39.4 — Neonatal skin infection

Billable / specific codeICD-10-CM

P39.4 is a billable, specific ICD-10-CM code for neonatal skin infection. It is valid for submission on a claim.

Excludes1 — never code together

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

pemphigus neonatorum (L00)
staphylococcal scalded skin syndrome (L00)

Inclusion terms

Alternative wordings a physician may use in the chart for this same code.

Neonatal pyoderma

Other codes that can never be billed with P39.4

These codes carry an Excludes1 note pointing at P39.4. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading P39.4 alone.

P83Other conditions of integument specific to newborn

Risk adjustment

P39.4 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.

How P39.4 is indexed

Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to P39.4.

Pyoderma, pyodermia›newborn
Infection, infected, infective›congenital›skin
