Acute reactive otitis externa, bilateral

This code signifies an acute inflammatory response of the external ear canal, not caused by infection, affecting both ears. It typically presents with symptoms like itching, pain, and discharge, often triggered by irritants or allergens.

Apply this code when documentation clearly indicates a non-infectious, acute inflammation of both external ear canals. This often occurs due to exposure to water, chemicals, or foreign bodies, and is supported by physician notes detailing bilateral involvement and the reactive nature of the condition.

• Differentiate from infectious otitis externa (e.g., bacterial, fungal) which requires different codes.
• Ensure documentation specifies "acute" and "reactive" to justify this specific code.
• Confirm bilateral involvement; unilateral cases would use codes specifying left or right ear.
