Infestation by Demodex mites

This code signifies a parasitic infestation of the skin by Demodex mites, commonly known as demodectic mange or demodicosis. These microscopic mites typically reside in hair follicles and sebaceous glands, and their overpopulation can lead to various dermatological symptoms.

Use this code when documentation clearly indicates a diagnosis of Demodex mite infestation. This often presents with symptoms such as facial redness, scaling, itching, burning sensations, or papules, particularly in conditions like rosacea-like demodicosis or folliculitis.

• Ensure the provider's documentation explicitly states "Demodex mites" or "demodicosis" as the causative agent.
• Do not confuse this with other parasitic infestations; this code is specific to Demodex.
• Consider co-coding with codes for associated dermatological conditions, such as rosacea (L71.-), if documented as being caused or exacerbated by the Demodex infestation.
