L12.2 — Chronic bullous disease of childhood
L12.2 is a billable, specific ICD-10-CM code for chronic bullous disease of childhood. It is valid for submission on a claim.
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Juvenile dermatitis herpetiformis
Other codes that can never be billed with L12.2
These codes carry an Excludes1 note pointing at L12.2. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading L12.2 alone.
- L13.0Dermatitis herpetiformis
Risk adjustment
L12.2 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
L12.2 is named in 2 Medicare coverage policies — 2 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
- A59101Billing and Coding: Off-label Use of Rituximab and Rituximab Biosimilars
- A60186Billing and Coding: Off-label Use of Rituximab and Rituximab Biosimilars
How L12.2 is indexed
