Oth disorders of ext ear in diseases classd elswhr, bi

This code signifies a bilateral manifestation of an external ear disorder that is secondary to, or a symptom of, another underlying disease process. It describes conditions affecting both external ears (auricle and external auditory canal) that are not specifically categorized elsewhere and are linked to a primary systemic or localized illness.

Apply this code when documentation indicates a bilateral external ear disorder clearly attributed to another disease, such as dermatological conditions (e.g., bilateral eczematous otitis externa secondary to systemic eczema) or systemic infections. The medical record must specify both the external ear involvement and the underlying causative disease.

• Always sequence the underlying disease code first, as this is a "manifestation" code.
• Ensure documentation explicitly states "bilateral" involvement; otherwise, use the appropriate unilateral or unspecified side code.
• Avoid using this code for primary external ear disorders not linked to another disease; instead, select a more specific code from H60-H61.
