Osseous obstruction of Eustachian tube, left ear

This diagnosis code signifies a blockage of the left Eustachian tube caused by abnormal bone growth or calcification. This osseous obstruction can lead to impaired middle ear ventilation, potentially resulting in conductive hearing loss, recurrent otitis media, or aural fullness.

Apply this code when documentation explicitly states an osseous obstruction of the left Eustachian tube. This typically follows imaging studies (e.g., CT scan) or endoscopic examination confirming the bony nature of the blockage. It is appropriate for patients presenting with symptoms related to Eustachian tube dysfunction where a bony etiology is identified.

• Ensure the documentation specifies "osseous" or "bony" obstruction, not just general Eustachian tube dysfunction.
• Verify laterality; this code is specific to the left ear. Use the appropriate code for the right ear (H68.111) or bilateral (H68.113) if applicable.
• Consider sequencing this code as a primary diagnosis if it is the main reason for the encounter, or as a secondary diagnosis if it is a co-morbidity impacting treatment.
