Patulous Eustachian tube, right ear

This code signifies a patulous Eustachian tube affecting the right ear. This condition occurs when the Eustachian tube, which normally remains closed, stays persistently open, leading to autophony (hearing one's own voice or breathing sounds loudly) and a sensation of ear fullness.

Use this code when documentation clearly indicates a diagnosis of patulous Eustachian tube specifically in the right ear. This diagnosis is often supported by patient complaints of autophony, aural fullness, and sometimes a "popping" sensation, confirmed by otoscopic examination or tympanometry findings.

• Ensure laterality is explicitly documented as "right ear" to support this specific code.
• Distinguish from Eustachian tube dysfunction (H69.8X) where the tube is typically obstructed or poorly functioning, rather than persistently open.
• Consider any associated symptoms or underlying causes that may require additional coding, such as weight loss or hormonal changes.
