Patient EducationClinical

Hair Loss

You lose up to 100 hairs from your scalp every day. That's normal, and in most people, those hairs grow back. But many men -- and some women -- lose hair as they grow older. You can also lose your hair if you have certain diseases, such as thyroid problems, diabetes, or lupus.

Questions About L64Overview

What is the ICD-10 code for androgenic alopecia?

L64 is the ICD-10-CM category for androgenic alopecia, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is L64 (Androgenic alopecia) a billable code?

No. This is a category header that groups the codes for androgenic alopecia, and headers cannot be submitted on claims. Claims for androgenic alopecia need a more specific code from this category, such as L64.0, L64.8, and L64.9.

Can L64 be reported with a code from Q84?

Not as a rule. The Excludes1 note at block L60-L75, which applies to L64, lists "congenital malformations of integument (Q84.-)". 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).
