ICD-10 Code H68.112 – Osseous obstruction of Eustachian tube, left ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H68.112 – Osseous obstruction of Eustachian tube, left ear
What it is
This code identifies a bony blockage affecting the left Eustachian tube. It means the tube is obstructed by osseous tissue, which can interfere with normal middle-ear ventilation.
Clinical signs
Clinical features vary; refer to documentation. Patients may have symptoms consistent with Eustachian tube dysfunction, such as ear fullness, pressure, or hearing changes, but the record should support the specific left-sided osseous obstruction.
When to use this code
Use this code when the clinician documents osseous obstruction of the left Eustachian tube as the diagnosis. It is appropriate when imaging, endoscopy, or specialist assessment supports a bony cause rather than a nonspecific blockage. Check documentation if laterality or cause is unclear.
Do not use for
Do not use it for unspecified Eustachian tube dysfunction, inflammatory obstruction, or right-sided disease. If the obstruction is not documented as osseous, code the condition that is actually stated.
Coding tip
Confirm both laterality and the bony nature of the obstruction before assigning H68.112.
