ICD-10 Code H68.101 – Unspecified obstruction of Eustachian tube, right ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H68.101 – Unspecified obstruction of Eustachian tube, right ear
What it is
This code identifies blockage or impaired opening of the Eustachian tube in the right ear when the cause is not specified. It is used when documentation confirms obstruction but does not name a more specific disorder.
Clinical signs
Typical findings include ear fullness, pressure, muffled hearing, or popping sensations. Clinical features vary; refer to documentation, and confirm the right ear is affected.
When to use this code
Use H68.101 when the record states right-sided Eustachian tube obstruction without further detail. It may also fit when the clinician documents dysfunction or blockage but does not identify a more specific etiology or laterality beyond the right ear.
Do not use for
Do not use this code if the chart identifies a specific cause, such as infection, mass, or another named ear disorder. Check documentation if the condition is bilateral or the side is not clearly right.
Coding tip
Verify laterality and specificity before assigning H68.101, because a more detailed diagnosis should take priority when documented.
