ICD-10 Code H80.82 – Other otosclerosis, left ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H80.82 – Other otosclerosis, left ear
What it is
H80.82 identifies otosclerosis affecting the left ear when the record specifies a form other than the common stapedial type. It is a progressive bone disorder of the middle ear that can reduce sound conduction.
Clinical signs
Clinical features vary; refer to documentation. Typical findings include conductive hearing loss, tinnitus, and abnormal audiology consistent with otosclerosis. The left ear must be clearly identified in the chart.
When to use this code
Use H80.82 when the clinician documents other otosclerosis limited to the left ear. This may appear in an otology assessment, audiology report, or operative note. If the type is not specified, check documentation before coding.
Do not use for
Do not use this code for otosclerosis of the right ear, bilateral disease, or unspecified ear. Check documentation if the note describes conductive hearing loss without a confirmed otosclerosis diagnosis.
Coding tip
Verify both laterality and the “other” otosclerosis wording before assigning H80.82.
