ICD-10 Code H81.312 – Aural vertigo, left ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H81.312 – Aural vertigo, left ear
What it is
H81.312 identifies vertigo attributed to the left ear. Use it when documentation states aural vertigo affecting the left side and the clinician links the dizziness to ear disease or dysfunction.
Clinical signs
Clinical features vary; refer to documentation. Typical notes may include spinning sensation, imbalance, or positional worsening, with findings pointing to a left-ear source rather than a central neurologic cause.
When to use this code
Use this code when the provider documents aural vertigo, left ear, or clearly states vertigo originating from the left ear. It is appropriate when the laterality is specified in the record. If the ear side is not documented, check documentation before assigning a laterality-specific code.
Do not use for
Do not use this code for nonspecific dizziness, generalized vertigo without ear attribution, or vertigo linked to another cause. If the record does not identify the left ear, do not assume laterality.
Coding tip
Match the code to the documented ear side and the provider’s stated cause; laterality matters here.
