Inclusion terms

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

  • Impetigo neonatorum
  • Pemphigus neonatorum

Other codes that can never be billed with L01.03

These codes carry an Excludes1 note pointing at L01.03. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading L01.03 alone.

  • L10Pemphigus
  • L00Staphylococcal scalded skin syndrome

Risk adjustment

L01.03 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.

Medicare coverage

L01.03 is named in 1 Medicare coverage policy 1 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
