ICD-10 Code H90.41 – Sensorineural hearing loss, unilateral, right ear, with unrestricted hearing on the contralateral side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H90.41 – Sensorineural hearing loss, unilateral, right ear, with unrestricted hearing on the contralateral side
What it is
This code identifies sensorineural hearing loss affecting the right ear only, while hearing in the left ear remains unrestricted. It reflects inner ear or auditory nerve involvement, not a conductive problem.
Clinical signs
Patients may report reduced hearing on the right, trouble understanding speech, or needing repetition, especially in noise. Clinical features vary; refer to documentation.
When to use this code
Use H90.41 when the record clearly documents unilateral sensorineural hearing loss in the right ear and normal or unrestricted hearing on the opposite side. Apply it for confirmed audiology findings or clinician assessment. Check documentation if laterality or type is unclear.
Do not use for
Do not use this code for conductive hearing loss, bilateral sensorineural loss, or unspecified hearing loss. If the chart does not confirm right-sided involvement, check documentation.
Coding tip
Confirm both laterality and sensorineural type in the note or audiogram before assigning H90.41.
