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 L65Overview

What is the ICD-10 code for other nonscarring hair loss?

L65 is the ICD-10-CM category for other nonscarring hair loss, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is L65 (Other nonscarring hair loss) a billable code?

No. This is a category header that groups the codes for other nonscarring hair loss, and headers cannot be submitted on claims. Claims for other nonscarring hair loss need a more specific code from this category, such as L65.0, L65.1, and L65.2.

Can L65 be reported with F63.3?

Not as a rule. The Excludes1 note on L65 lists "trichotillomania (F63.3)". 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).

Does L65 need an additional code?

When the condition applies, yes. The Use Additional Code note reads: code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5). The additional code is reported after L65.
