ICD-10 Code H90.11 – Conductive hearing loss, unilateral, right ear, with unrestricted hearing on the contralateral side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H90.11 – Conductive hearing loss, unilateral, right ear, with unrestricted hearing on the contralateral side
What it is
This code identifies conductive hearing loss limited to the right ear, while the left ear has normal hearing. The problem is in sound transmission through the outer or middle ear, not the inner ear.
Clinical signs
Patients may report reduced hearing on the right side, muffled sound, or difficulty understanding speech when sound comes from that ear. Clinical features vary; refer to documentation, audiology results, and provider assessment.
When to use this code
Use H90.11 when the record clearly documents unilateral conductive hearing loss in the right ear and normal hearing on the opposite side. It fits cases confirmed by exam, audiology testing, or specialist assessment. Make sure the laterality is stated.
Do not use for
Do not use this code for sensorineural or mixed hearing loss, or when both ears are affected. Check documentation if the record does not specify right-sided conductive loss with unrestricted hearing in the left ear.
Coding tip
Verify laterality and hearing type in the note or audiogram before assigning H90.11.
