Hearing Disorders and Deafness

It's frustrating to be unable to hear well enough to enjoy talking with friends or family. Hearing disorders make it hard, but not impossible, to hear. They can often be helped. Deafness can keep you from hearing sound at all.

Questions About H91Overview

What is the ICD-10 code for other and unspecified hearing loss?

H91 is the ICD-10-CM category for other and unspecified hearing loss, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is H91 (Other and unspecified hearing loss) a billable code?

No. This is a category header that groups the codes for other and unspecified hearing loss, and headers cannot be submitted on claims. Claims for other and unspecified hearing loss need a more specific code from this category, such as H91.01, H91.02, and H91.03.

Can H91 be reported with a code from H93.2?

Not as a rule. The Excludes1 note on H91 lists "abnormal auditory perception (H93.2-)". 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).
