ICD-10 Code H68.113 – Osseous obstruction of Eustachian tube, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H68.113 – Osseous obstruction of Eustachian tube, bilateral
What it is
Use this code for a bony blockage affecting both Eustachian tubes. It indicates impaired tube opening due to osseous obstruction, which can interfere with normal middle-ear ventilation.
Clinical signs
Clinical features vary; refer to documentation. Commonly noted findings may include bilateral ear fullness, pressure, muffled hearing, or evidence of Eustachian tube dysfunction on examination.
When to use this code
Assign H68.113 when the record specifically documents osseous obstruction of the Eustachian tube on both sides. Use it for confirmed anatomic obstruction, not for vague ear pressure or nonspecific dysfunction alone. If laterality or cause is unclear, check documentation.
Do not use for
Do not use this code for unilateral obstruction, simple Eustachian tube dysfunction, or middle-ear disease without documented osseous blockage. Check documentation if the note only mentions congestion or otitis media.
Coding tip
Verify both laterality and the word “osseous” in the provider note before assigning H68.113.
