Total perforations of tympanic membrane, left ear

This code signifies a complete disruption or hole in the eardrum of the left ear. This perforation extends across the entire tympanic membrane, rather than being a partial defect. It often results in hearing loss and can expose the middle ear to infection.

Use this code when documentation clearly indicates a total perforation of the left tympanic membrane. This typically occurs following trauma, severe infection (e.g., otitis media with effusion), or surgical intervention. Documentation should specify "total," "complete," or describe a large defect encompassing the entire eardrum.

• Differentiate between total and partial perforations; partial perforations have different codes.
• Always specify laterality (left, right, or bilateral) as distinct codes exist for each.
• Consider an external cause code if the perforation is due to trauma.
