ICD-10 Code H90.7 – Mixed conductive and sensorineural hearing loss, unilateral with unrestricted hearing on the contralateral side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H90.7 – Mixed conductive and sensorineural hearing loss, unilateral with unrestricted hearing on the contralateral side
What it is
This code identifies hearing loss in one ear that has both conductive and sensorineural components, while the other ear hears normally. Use it when documentation clearly states unilateral mixed hearing loss with the opposite ear unrestricted.
Clinical signs
Clinical features vary; refer to documentation. Common findings include reduced hearing in one ear, abnormal audiology results, and evidence of both middle-ear and inner-ear involvement on the affected side.
When to use this code
Use H90.7 when the record specifies mixed hearing loss affecting only one ear and indicates normal hearing in the other ear. It may be supported by audiology, ENT notes, or a provider’s final diagnosis. If the chart does not confirm both components, check documentation.
Do not use for
Do not use this code for bilateral mixed hearing loss or for conductive-only or sensorineural-only loss. If the unaffected ear is not documented as unrestricted, verify the laterality before coding.
Coding tip
Confirm both the mixed type and unilateral laterality in the assessment, not just in test results.
