ICD-10 Code H69.02 – Patulous Eustachian tube, left ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H69.02 – Patulous Eustachian tube, left ear
What it is
H69.02 identifies a patulous Eustachian tube in the left ear. This means the tube stays abnormally open, which can cause abnormal sound transmission and ear pressure complaints.
Clinical signs
Common findings include autophony, hearing one’s own voice or breathing loudly, and intermittent aural fullness. Clinical features vary; refer to documentation.
When to use this code
Use H69.02 when the provider documents patulous Eustachian tube specifically in the left ear. Apply it for confirmed laterality in outpatient, specialty, or hospital records. If the note only says “patulous Eustachian tube” without ear side, check documentation.
Do not use for
Do not use this code for obstructive Eustachian tube dysfunction, otitis media, or nonspecific ear pressure without a documented patulous tube. Do not assume left-sided involvement unless stated.
Coding tip
Always verify laterality and the exact phrase “patulous Eustachian tube” before assigning H69.02.
