Clinical InformationClinical

  • Pemphigoid, Bullous

    a chronic and relatively benign subepidermal blistering disease usually of the elderly and without histopathologic acantholysis.

Patient EducationClinical

Pemphigus

Pemphigus is an autoimmune disorder. If you have it, your immune system attacks healthy cells in your skin and mouth, causing blisters and sores. No one knows the cause. Pemphigus does not spread from person to person. It does not appear to be inherited. But some people's genes put them more at risk for pemphigus.

Questions About L12Overview

What is the ICD-10 code for pemphigoid?

L12 is the ICD-10-CM category for pemphigoid, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is L12 (Pemphigoid) a billable code?

No. This is a category header that groups the codes for pemphigoid, and headers cannot be submitted on claims. Claims for pemphigoid need a more specific code from this category, such as L12.0, L12.1, and L12.2.

Can L12 be reported with a code from O26.4?

Not as a rule. The Excludes1 note on L12 lists "herpes gestationis (O26.4-)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
