ICD-10 Code H68.111 – Osseous obstruction of Eustachian tube, right ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H68.111 – Osseous obstruction of Eustachian tube, right ear
What it is
This code identifies a bony blockage of the Eustachian tube on the right side. It means the tube cannot open normally to equalize pressure and drain the middle ear.
Clinical signs
Patients may report ear fullness, pressure, muffled hearing, or discomfort on the right. Clinical features vary; refer to documentation, and confirm the obstruction is specifically osseous.
When to use this code
Use H68.111 when the provider documents osseous obstruction affecting the right Eustachian tube. It is appropriate when imaging, endoscopy, or operative findings specify a bony cause rather than a general Eustachian tube dysfunction. Code the documented laterality exactly.
Do not use for
Do not use this code for nonspecific Eustachian tube dysfunction, inflammation, or fluid in the middle ear without a documented bony obstruction. Check documentation if the cause or side is not clearly stated.
Coding tip
Verify both the osseous cause and right-sided laterality in the record before assigning H68.111.
