ICD-10 Code H91.12 – Presbycusis, left ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H91.12 – Presbycusis, left ear
What it is
H91.12 identifies age-related hearing loss affecting the left ear. Use it when documentation specifically states presbycusis on the left side.
Clinical signs
Typical findings include gradual, bilateral-or-unilateral hearing decline with trouble understanding speech, especially in noisy settings. Clinical features vary; refer to documentation.
When to use this code
Use H91.12 when the clinician documents presbycusis limited to the left ear. It fits outpatient, specialty, or audiology notes that clearly identify the side and the diagnosis. If the record only says hearing loss without presbycusis, check documentation before coding this specific code.
Do not use for
Do not use this code for unspecified hearing loss, conductive hearing loss, or sensorineural loss without a documented presbycusis diagnosis. Do not assume laterality if the chart does not state left ear.
Coding tip
Confirm both the age-related diagnosis and the left-ear laterality in the provider note before assigning H91.12.
