Hearing loss is one of the most common sensory impairments worldwide, affecting millions of people across all age groups. For healthcare professionals, accurate diagnosis and documentation are essential — and that’s where ICD-10 codes for hearing loss come in. These codes help classify different types and causes of hearing loss, ensuring proper treatment, billing, and medical record accuracy.
What Is the ICD-10 Code for Hearing Loss?
The International Classification of Diseases, 10th Revision (ICD-10) is a coding system developed by the World Health Organization (WHO). It provides standardized codes for diseases, symptoms, and medical conditions, allowing healthcare providers to maintain consistency in diagnosis and treatment.
When it comes to hearing loss, ICD-10 includes specific codes that identify the type, severity, and cause of the impairment. Accurate coding helps determine the best treatment plan and ensures insurance claims are processed correctly.

Common ICD-10 Codes for Hearing Loss
Here are some of the most frequently used ICD-10 codes related to hearing loss:
- H90.0 – Conductive hearing loss, bilateral
- H90.3 – Sensorineural hearing loss, bilateral
- H91.90 – Unspecified hearing loss, unspecified ear
- H91.91 – Unspecified hearing loss, right ear
- H91.92 – Unspecified hearing loss, left ear
- H91.93 – Unspecified hearing loss, bilateral
- H90.5 – Unspecified sensorineural hearing loss
- H91.20 – Sudden idiopathic hearing loss, unspecified ear
Each code helps medical professionals describe whether the hearing loss is conductive, sensorineural, or mixed, and whether it affects one or both ears.
Types of Hearing Loss Explained
Conductive Hearing Loss:
This type occurs when sound waves cannot travel efficiently through the ear canal, eardrum, or middle ear. Common causes include ear infections, wax buildup, or eardrum damage.
Sensorineural Hearing Loss:
This is the most common type of permanent hearing loss, caused by damage to the inner ear (cochlea) or auditory nerve. Aging, loud noise exposure, or certain medications are frequent contributors.
Mixed Hearing Loss:
A combination of both conductive and sensorineural components, requiring comprehensive evaluation and treatment.
Importance of Accurate Coding
Properly using the ICD-10 hearing loss codes ensures accurate diagnosis and effective management. It also supports research, healthcare planning, and patient data tracking across medical systems. For patients, correct coding means smoother insurance processing and access to hearing aids, implants, or therapy services when needed.
When to Seek Medical Help
If you experience symptoms like muffled hearing, ringing in the ears (tinnitus), or difficulty following conversations, consult an audiologist or ENT specialist. Early diagnosis can prevent further deterioration and improve treatment outcomes.
Understanding hearing loss ICD-10 codes is crucial for both medical professionals and patients. These codes not only standardize diagnosis but also ensure timely and appropriate care. Whether the hearing loss is temporary or permanent, early evaluation and proper documentation are key to preserving your hearing health.
