ICD-10 Code H93.A2 – Pulsatile tinnitus, left ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H93.A2 – Pulsatile tinnitus, left ear
What it is
H93.A2 identifies pulsatile tinnitus affecting the left ear. Use it when the patient reports a rhythmic sound that matches the heartbeat and is documented as limited to the left side.
Clinical signs
Typical documentation includes a pulse-synchronous whooshing, thumping, or beating sound heard in the left ear. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider clearly documents pulsatile tinnitus in the left ear, whether as the main complaint or a secondary finding. It may appear in ENT, neurology, or vascular workups. If laterality is not stated, check documentation before coding.
Do not use for
Do not use H93.A2 for nonpulsatile tinnitus, bilateral symptoms, or tinnitus with unspecified laterality. Check documentation if the record only says “tinnitus” or does not confirm the left ear.
Coding tip
Verify both the pulsatile nature and left-ear laterality in the provider note before assigning H93.A2.
