ICD-10 Code H90.0 – Conductive Hearing Loss, Bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H90.0 – Conductive hearing loss, bilateral
What it is
H90.0 identifies conductive hearing loss affecting both ears. It means sound is not traveling normally through the outer or middle ear to the inner ear.
Clinical signs
Typical findings include reduced hearing, difficulty understanding speech, and abnormal hearing test results consistent with a conductive pattern. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents bilateral conductive hearing loss as the diagnosis. It may apply when audiology or otologic evaluation supports a conductive deficit in both ears. If the record only states hearing loss without laterality or type, check documentation.
Do not use for
Do not use H90.0 for sensorineural, mixed, or unspecified hearing loss. Do not assign it when the chart does not clearly document bilateral conductive loss.
Coding tip
Confirm both the conductive type and bilateral involvement in the provider note before assigning H90.0.
