ICD-10 Code H90.72 – Mixed conductive and sensorineural hearing loss, unilateral, left ear, with unrestricted hearing on the contralateral side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H90.72 – Mixed conductive and sensorineural hearing loss, unilateral, left ear, with unrestricted hearing on the contralateral side
What it is
This code identifies mixed hearing loss in the left ear, meaning both conductive and sensorineural components are present. The right ear has normal, unrestricted hearing.
Clinical signs
Patients may have reduced hearing on the left side, difficulty understanding speech, and abnormal audiology results showing both air-bone gap and inner ear involvement. Clinical features vary; refer to documentation.
When to use this code
Use H90.72 when the record clearly documents mixed hearing loss limited to the left ear and the opposite ear is normal. You may also use it when audiology or specialist notes support unilateral mixed loss with no bilateral involvement. Check documentation if laterality or type is unclear.
Do not use for
Do not use this code for conductive-only or sensorineural-only hearing loss, or for bilateral hearing loss. It is also wrong when the affected ear is not specified as left.
Coding tip
Confirm both components and laterality in the audiology or ENT note before assigning H90.72.
