ICD-10 Code H68.139 – Extrinsic cartilagenous obstruction of Eustachian tube, unspecified ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H68.139 – Extrinsic cartilagenous obstruction of Eustachian tube, unspecified ear
What it is
This code identifies obstruction of the cartilaginous part of the Eustachian tube caused by an external factor, with the ear side not specified. Use it when documentation states this exact type of obstruction and does not name left or right ear.
Clinical signs
Clinical features vary; refer to documentation. Commonly noted findings may include Eustachian tube dysfunction, ear fullness, muffled hearing, or pressure symptoms, but you should code only what is documented.
When to use this code
Use this code when the provider documents extrinsic cartilagenous obstruction of the Eustachian tube and does not specify the affected ear. It may also fit follow-up visits where the same diagnosis is still active. Check documentation for laterality if it is available.
Do not use for
Do not use it for generic Eustachian tube dysfunction, middle ear disease, or obstruction with a different stated cause. If the record does not clearly support an extrinsic cartilaginous obstruction, check documentation.
Coding tip
Match the code to the exact wording in the note and confirm whether the ear is unspecified or laterality is documented elsewhere.
