ICD-10 Code H90.6 – Mixed conductive and sensorineural hearing loss, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H90.6 – Mixed conductive and sensorineural hearing loss, bilateral
What it is
H90.6 identifies hearing loss in both ears that has both conductive and sensorineural components. Use it when documentation shows a mixed type affecting the left and right ears.
Clinical signs
Patients may have reduced hearing from middle-ear transmission problems and inner-ear dysfunction. Clinical features vary; refer to documentation for audiology findings or otologic assessment supporting a mixed bilateral pattern.
When to use this code
Use H90.6 when the provider documents bilateral mixed hearing loss, or when testing clearly supports both conductive and sensorineural loss in each ear. Code it for chronic hearing impairment, not a transient symptom alone. If laterality or type is unclear, check documentation.
Do not use for
Do not use this code for purely conductive or purely sensorineural hearing loss. Avoid it when the record does not confirm bilateral involvement or when the diagnosis is only suspected.
Coding tip
Confirm both the mixed component and bilateral laterality in the assessment before assigning H90.6.
