Clinical InformationClinical

  • Pemphigus

    group of chronic blistering diseases characterized histologically by acantholysis and blister formation within the epidermis.

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 L10Overview

What is the ICD-10 code for pemphigus?

L10 is the ICD-10-CM category for pemphigus, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is L10 (Pemphigus) a billable code?

No. This is a category header that groups the codes for pemphigus, and headers cannot be submitted on claims. Claims for pemphigus need a more specific code from this category, such as L10.0, L10.1, and L10.2.

Can L10 be reported with L01.03?

Not as a rule. The Excludes1 note on L10 lists "pemphigus neonatorum (L01.03)". 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).
