ICD-10 Code H68.103 – Unspecified obstruction of Eustachian tube, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H68.103 – Unspecified obstruction of Eustachian tube, bilateral
What it is
This code identifies blockage or poor opening of both Eustachian tubes when the cause is not specified. It indicates impaired pressure equalization and drainage between the middle ear and nasopharynx.
Clinical signs
Common findings include ear fullness, pressure, muffled hearing, or popping sensations. Clinical features vary; refer to documentation, especially when the record does not identify a specific cause.
When to use this code
Use H68.103 when the provider documents bilateral Eustachian tube obstruction without naming an underlying condition. It also fits when the note describes blocked or nonfunctioning tubes on both sides and no more specific code is supported.
Choose this code only after reviewing the chart for otitis media, allergic rhinitis, or other documented causes that may require different coding. Check documentation if laterality or etiology is unclear.
Do not use for
Do not use this code for unilateral Eustachian tube obstruction or for a clearly documented specific disorder causing the obstruction. If the record states a different diagnosis, code that condition instead.
Coding tip
Confirm bilateral involvement and the absence of a documented cause before assigning H68.103.
