ICD-10 Code H90.A22 – Sensorineural hearing loss, unilateral, left ear, with restricted hearing on the contralateral side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H90.A22 – Sensorineural hearing loss, unilateral, left ear, with restricted hearing on the contralateral side
What it is
This code identifies sensorineural hearing loss affecting the left ear, with limited hearing in the opposite ear. Use it when documentation specifies unilateral left-sided loss plus restricted hearing on the contralateral side.
Clinical signs
Typical findings include reduced hearing sensitivity on the left and impaired hearing in the right ear, though the degree may vary. Clinical features vary; refer to documentation.
When to use this code
Use H90.A22 when the record clearly states left-sided sensorineural hearing loss and notes restricted hearing in the other ear. It is appropriate for audiology, ENT, or problem-list documentation that distinguishes this pattern from bilateral or conductive loss. If the laterality or type is unclear, check documentation.
Do not use for
Do not use this code for conductive hearing loss, mixed hearing loss, or unspecified hearing loss. Avoid it when the chart does not document left-sided sensorineural loss with contralateral restriction.
Coding tip
Verify both laterality and sensorineural type in the note before assigning H90.A22.
