ICD-10 Code H68.131 – Extrinsic cartilagenous obstruction of Eustachian tube, right ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H68.131 – Extrinsic cartilagenous obstruction of Eustachian tube, right ear
What it is
This code identifies blockage of the right Eustachian tube caused by pressure or compression from outside the tube, specifically in the cartilaginous portion. It means the tube cannot open and equalize pressure normally.
Clinical signs
Typical findings include ear fullness, pressure, muffled hearing, or popping with swallowing. Clinical features vary; refer to documentation for right-sided Eustachian tube obstruction and its cause.
When to use this code
Use H68.131 when the record clearly states extrinsic cartilaginous obstruction of the right Eustachian tube. Apply it when the provider links the obstruction to an outside compressive process, not to infection or simple dysfunction.
Check documentation if the note only mentions ear pain, congestion, or unspecified Eustachian tube disorder. You need laterality and the specific obstruction type to support this code.
Do not use for
Do not use this code for left or bilateral obstruction, or for nonspecific Eustachian tube dysfunction. If the cause is not documented as extrinsic cartilaginous obstruction, check documentation.
Coding tip
Verify both laterality and the exact wording “extrinsic cartilagenous obstruction” before assigning H68.131.
