ICD-10 Code H90.A – Conductive and sensorineural hearing loss with restricted hearing on the contralateral side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H90.A – Conductive and sensorineural hearing loss with restricted hearing on the contralateral side
What it is
This code identifies a mixed hearing loss pattern in one ear, with limited hearing in the opposite ear. Use it when documentation specifically states conductive and sensorineural hearing loss with contralateral restriction.
Clinical signs
Findings may include reduced hearing on testing, with features of both conductive and sensorineural loss. Clinical features vary; refer to documentation.
When to use this code
Use H90.A when the record clearly describes this exact asymmetric hearing-loss pattern. It may apply when audiology or otology documentation names conductive and sensorineural loss with restricted hearing on the other side. Check documentation if the laterality or type is not explicit.
Do not use for
Do not use this code for unspecified hearing loss, single-type conductive loss, or isolated sensorineural loss. If the note does not confirm contralateral restriction, check documentation.
Coding tip
Verify the audiology or specialist note for the exact wording before assigning H90.A.
