ICD-10 Code H90.A11 – Conductive hearing loss, unilateral, right ear with restricted hearing on the contralateral side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H90.A11 – Conductive hearing loss, unilateral, right ear with restricted hearing on the contralateral side
What it is
This code identifies conductive hearing loss in the right ear, with the left ear also having restricted hearing. It describes a hearing problem caused by impaired sound conduction, not a sensorineural loss.
Clinical signs
Typical findings include reduced hearing on audiology testing, often with air-bone gap consistent with conductive loss. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record clearly documents unilateral conductive hearing loss in the right ear and restricted hearing in the opposite ear. It is appropriate when audiology or provider documentation supports this specific laterality and hearing pattern. Check documentation if the contralateral ear finding is unclear.
Do not use for
Do not use this code for sensorineural or mixed hearing loss, or for unspecified hearing loss. Do not assign it if the right ear laterality or contralateral restriction is not documented.
Coding tip
Verify both ear findings in the note or audiology report before assigning H90.A11.
