Otitis externa in oth diseases classd elswhr, right ear

This code signifies an inflammation of the external ear canal (otitis externa) that is a manifestation of, or secondary to, another underlying systemic disease. This condition specifically affects the right ear. The primary disease causing the otitis externa must be separately identified and coded.

Apply this code when documentation clearly indicates otitis externa in the right ear is a symptom or complication of another classified disease, such as diabetes mellitus, psoriasis, or a systemic fungal infection. The medical record must specify the underlying disease and confirm the right ear involvement.

• Always sequence the underlying systemic disease code first, followed by this code.
• Ensure documentation explicitly links the otitis externa to the specified systemic disease.
• Do not use this code for primary otitis externa or otitis externa due to local causes (e.g., swimming, trauma) without an underlying systemic condition.
