L26Exfoliative dermatitis

Billable / specific codeICD-10-CM

  • Ritter's disease (L00)

Inclusion terms

Risk adjustment

L26 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

L26 is named in 10 Medicare coverage policies 10 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
