ICD-10 Code H68.11 – Osseous obstruction of Eustachian tube (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H68.11 – Osseous obstruction of Eustachian tube
What it is
H68.11 identifies blockage of the Eustachian tube caused by bone or bony narrowing. Use it when documentation specifically states an osseous obstruction rather than a general tube dysfunction.
Clinical signs
Clinical features vary; refer to documentation. Commonly noted findings may include ear fullness, pressure, muffled hearing, or recurrent middle ear fluid when the tube cannot ventilate properly.
When to use this code
Use this code when the provider documents osseous obstruction of the Eustachian tube or a bony cause of Eustachian tube blockage. It may appear in ENT evaluations, imaging reports, or operative notes describing structural narrowing. If the note only says Eustachian tube dysfunction, check documentation.
Do not use for
Do not use H68.11 for nonspecific Eustachian tube dysfunction, inflammatory blockage, or otitis media without documented osseous obstruction. Check documentation if the cause is unclear.
Coding tip
Code H68.11 only when the record clearly ties the obstruction to bone; otherwise query for the specific cause.
