ICD-10 Code H90.2 – Conductive hearing loss, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H90.2 – Conductive hearing loss, unspecified
What it is
H90.2 identifies conductive hearing loss when the cause or laterality is not further specified. It means sound is not being transmitted normally through the outer or middle ear.
Clinical signs
Patients may report muffled hearing, reduced hearing on one or both sides, or difficulty understanding speech. Clinical features vary; refer to documentation for the exact ear findings and cause.
When to use this code
Use H90.2 when the record documents conductive hearing loss but does not specify the ear, cause, or whether it is unilateral or bilateral. It also fits when the provider confirms conductive loss and no more detailed diagnosis is available. Check documentation if a more specific code is supported.
Do not use for
Do not use this code for sensorineural or mixed hearing loss. Avoid it when the chart identifies a specific conductive cause or laterality that should be coded more precisely.
Coding tip
Review the assessment, audiology notes, and problem list for a more specific hearing-loss code before defaulting to H90.2.
