Sensorineural hearing loss, unilateral, left ear, with restricted hearing on the contralateral side

H90.A22 (“Sensorineural hearing loss, unilateral, left ear, with restricted hearing on the contralateral side”) is a diagnosis code that identifies a specific condition, injury, or finding on a medical claim in the ICD-10-CM code set. Whether it is billed — and whether a payer covers it — depends on the clinical setting, documentation, and plan rules.
