ICD-10 Code H93.291 – Other Abnormal Auditory Perceptions, Right Ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H93.291 – Other abnormal auditory perceptions, right ear
What it is
This code identifies abnormal sound perception limited to the right ear when the documented complaint does not fit a more specific diagnosis. It covers unusual auditory sensations such as nonstandard hearing perceptions, not hearing loss itself.
Clinical signs
Patients may report unusual sounds, distorted hearing, or other abnormal auditory sensations in the right ear. Clinical features vary; refer to documentation.
When to use this code
Use H93.291 when the provider documents an abnormal auditory perception affecting the right ear and no more specific ear disorder is named. It is appropriate for office, specialty, or follow-up notes that clearly localize the finding to the right side. Check documentation if the record is vague.
Do not use for
Do not use this code for hearing loss, tinnitus, or generalized ear symptoms without right-ear localization. If another diagnosis better explains the complaint, code that condition instead.
Coding tip
Confirm the right-ear laterality and the exact wording in the note before assigning H93.291.
