ICD-10 Code H90.8 – Mixed conductive and sensorineural hearing loss, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H90.8 – Mixed conductive and sensorineural hearing loss, unspecified
What it is
This code identifies hearing loss with both conductive and sensorineural components, but the type is not further specified. Use it when documentation confirms mixed hearing loss without naming a side or more detail.
Clinical signs
Patients may have reduced hearing from both middle-ear and inner-ear involvement. Clinical features vary; refer to documentation, audiology results, and the provider’s stated diagnosis.
When to use this code
Use H90.8 when the record clearly states mixed conductive and sensorineural hearing loss and no laterality or added detail is provided. It fits encounters where the diagnosis is established, but the note does not support a more specific code.
Choose this code after reviewing the assessment, audiology report, and problem list. If documentation only says hearing loss without specifying mixed type, check documentation before coding.
Do not use for
Do not use this code for purely conductive or purely sensorineural hearing loss. It also should not be used when the chart documents a more specific mixed hearing loss code.
Coding tip
Code only what the provider documents; if mixed hearing loss is implied but not stated, query or check documentation.
