Central perforation of tympanic membrane, left ear

This code signifies a hole or defect located in the central part of the eardrum (tympanic membrane) specifically affecting the left ear. This perforation can result from various causes, including infection, trauma, or pressure changes, and may lead to hearing loss or recurrent ear infections.

Apply this code when documentation clearly indicates a central perforation of the tympanic membrane in the left ear. This diagnosis is typically made during an otoscopic examination by a physician. Supporting documentation should include findings from the physical exam, patient history of ear issues, and potentially audiometry results.

• Differentiate between central and marginal perforations; the location impacts code selection.
• Ensure the laterality (left ear) is explicitly documented to support this specific code.
• Consider additional codes for the underlying cause (e.g., otitis media) if documented and still active.
