Other noninfective acute otitis externa, left ear

This code signifies an acute inflammatory condition of the left external auditory canal that is not caused by an infection. It encompasses various non-infectious etiologies, such as allergic reactions, chemical irritants, or trauma, leading to symptoms like pain, itching, and discharge. The inflammation is sudden in onset and typically resolves within a short period.

Apply this code when documentation clearly indicates acute otitis externa affecting the left ear, and the physician explicitly rules out an infectious cause. This includes cases of contact dermatitis, eczema, or other irritant-induced inflammation of the external ear canal. Supporting documentation should specify the non-infectious nature of the condition.

• Differentiate carefully between infectious (H60.3-) and non-infectious (H60.5-) otitis externa; physician documentation must specify the etiology.
• Ensure laterality is accurately documented and coded (left ear).
• Consider co-reporting with codes for underlying causes if known, such as contact dermatitis (L23.-) or other eczematous conditions (L30.-).
