Acute eczematoid otitis externa, bilateral

This code signifies an acute inflammatory condition affecting the external ear canal, characterized by eczema-like skin changes such as redness, itching, scaling, and weeping. The condition is non-infectious in nature and affects both ears simultaneously.

Apply this code when documentation specifies an acute, non-infectious eczematous inflammation of the external auditory canal present in both the left and right ears. Supporting documentation should clearly indicate the bilateral involvement and the eczematoid nature of the otitis externa.

• Differentiate from infectious otitis externa; this code is for non-infectious, eczematoid presentations.
• Ensure documentation explicitly states "bilateral" involvement; otherwise, a unilateral code or unspecified laterality code may be more appropriate.
• Consider additional codes for any underlying causes of the eczematoid reaction, such as contact dermatitis, if documented.
