Unspecified chronic otitis externa, left ear

This code signifies a persistent, non-specific inflammation of the external auditory canal affecting the left ear. It indicates a long-standing infection or inflammatory process without a definitive cause or specific pathological agent identified.

Apply this code when documentation clearly indicates chronic otitis externa in the left ear, but the specific type (e.g., mycotic, allergic) is not specified. This is appropriate when the provider has diagnosed chronic otitis externa but further diagnostic workup for etiology is pending or was inconclusive.

• Ensure documentation specifies "chronic" and "left ear" for accurate assignment.
• Avoid using this code if a more specific type of chronic otitis externa (e.g., H60.52 for acute noninfectious) is documented.
• Consider sequencing with codes for underlying conditions or complications if present.
