ICD-10 Code H83.3X2 – Noise effects on left inner ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H83.3X2 – Noise effects on left inner ear
What it is
This code identifies noise-related injury or effect involving the left inner ear. Use it when documentation specifically links the left inner ear to noise exposure.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings may include hearing difficulty, tinnitus, or other noise-related auditory complaints affecting the left ear.
When to use this code
Use this code when the provider documents noise effects limited to the left inner ear. It fits cases where the diagnosis is explicitly tied to acoustic injury or noise exposure.
If the record only says hearing loss, tinnitus, or ear pain without a noise-related inner-ear diagnosis, check documentation before assigning this code. Side-specific laterality should match the note.
Do not use for
Do not use this code for unspecified ear involvement or non-noise-related ear disorders. Do not assume laterality when the chart does not clearly identify the left inner ear.
Coding tip
Verify both the noise cause and left-sided laterality in the provider note before coding.
