Patulous Eustachian tube, unspecified ear

This code signifies a condition where the Eustachian tube, which normally remains closed, is abnormally open or patent. This persistent patency allows air to enter the middle ear with each breath, leading to autophony (hearing one's own voice or breathing sounds loudly) and a sensation of ear fullness or blockage. The "unspecified ear" designation indicates that the laterality of the condition is not documented.

Use this code when documentation clearly indicates a diagnosis of patulous Eustachian tube without specifying whether it affects the right or left ear. This typically occurs when a patient presents with symptoms like autophony, aural fullness, or hearing their own breathing, and clinical examination or patient history points to a persistently open Eustachian tube.

• Only use this code when laterality (right or left ear) is not specified in the medical record.
• If laterality is documented, use the more specific codes H69.01 (right ear) or H69.02 (left ear).
• Ensure documentation supports the diagnosis of a patulous Eustachian tube, differentiating it from other Eustachian tube dysfunctions.
