ICD-10 Code H69.01 – Patulous Eustachian tube, right ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H69.01 – Patulous Eustachian tube, right ear
What it is
This code identifies a patulous Eustachian tube affecting the right ear. It means the tube stays abnormally open, rather than closed, and the diagnosis is limited to the right side.
Clinical signs
Commonly documented findings include autophony, a sensation of hearing one’s own voice or breathing loudly, and ear fullness. Clinical features vary; refer to documentation.
When to use this code
Use H69.01 when the provider documents patulous Eustachian tube specifically in the right ear. It is appropriate when the note clearly distinguishes right-sided involvement from bilateral or unspecified disease. If laterality is not stated, check documentation before assigning this code.
Do not use for
Do not use this code for a blocked or dysfunctional Eustachian tube, or for symptoms alone without a documented diagnosis. If the side is not right-sided, choose the correct laterality or check documentation.
Coding tip
Confirm laterality in the assessment or impression, because this code is specific to the right ear.
