ICD-10 Code H83.3X9 – Noise effects on inner ear, unspecified ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H83.3X9 – Noise effects on inner ear, unspecified ear
What it is
Use this code for inner ear effects attributed to noise exposure when the affected ear is not specified. It indicates a hearing-related injury or disorder linked to noise, but documentation does not identify right or left ear.
Clinical signs
Typical findings include hearing difficulty, tinnitus, or a history of significant noise exposure. Clinical features vary; refer to documentation for the exact ear involved and whether the condition is acute or chronic.
When to use this code
Use H83.3X9 when the provider documents noise effects on the inner ear and does not specify the ear. It is appropriate when the note links the condition to occupational, recreational, or accidental noise exposure. If laterality is documented, use the more specific code instead.
Do not use for
Do not use this code for unspecified hearing loss without a documented noise-related inner ear effect. Do not use it when the record identifies a different ear disorder or clearly states another cause; check documentation.
Coding tip
Always look for laterality and the noise exposure source, because missing details may change code selection.
