ICD-10 Code H69.00 – Patulous Eustachian tube, unspecified ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H69.00 – Patulous Eustachian tube, unspecified ear
What it is
H69.00 identifies a patulous Eustachian tube in an unspecified ear. This means the tube stays abnormally open, which can disrupt normal ear pressure regulation.
Clinical signs
Common findings include autophony, where the patient hears their own voice or breathing unusually loudly. Clinical features vary; refer to documentation.
When to use this code
Use H69.00 when the record documents patulous Eustachian tube but does not specify the right or left ear. It is appropriate for outpatient or specialist notes that clearly name this diagnosis.
If the provider describes symptoms only, without confirming the condition, check documentation before coding. Choose a laterality-specific code when the affected ear is stated.
Do not use for
Do not use this code for general Eustachian tube dysfunction, obstruction, or middle ear disease unless patulous Eustachian tube is specifically documented. Check documentation.
Coding tip
Confirm whether the ear is specified; if not, H69.00 is the correct unspecified-ear option.
