Questions About L13Overview

What is the ICD-10 code for other bullous disorders?

L13 is the ICD-10-CM category for other bullous disorders, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is L13 (Other bullous disorders) a billable code?

No. This is a category header that groups the codes for other bullous disorders, and headers cannot be submitted on claims. Claims for other bullous disorders need a more specific code from this category, such as L13.0, L13.1, and L13.8.

Can L13 be reported with Q82.8?

Not as a rule. The Excludes1 note at block L10-L14, which applies to L13, lists "benign familial pemphigus [Hailey-Hailey] (Q82.8)". 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).
