Candidal otitis externa

This code signifies an infection of the external ear canal caused by Candida species, commonly known as a yeast infection. It presents with inflammation, itching, pain, and discharge in the outer ear, distinct from bacterial or fungal infections caused by other organisms.

Apply this code when documentation explicitly states "candidal otitis externa" or "yeast otitis externa." It is appropriate when laboratory cultures confirm Candida as the causative agent of an external ear infection.

• Ensure the documentation specifies Candida as the pathogen; do not use for unspecified fungal otitis externa.
• Distinguish from otitis externa caused by other fungi (e.g., aspergillosis), which would require a different code.
• Code any underlying conditions contributing to the candidal infection, such as diabetes or immunocompromised states, as additional diagnoses.
