Pediculus corporis [body louse]

This code signifies an infestation of the body by the human body louse, Pediculus humanus corporis. This ectoparasite lives in clothing seams and feeds on human blood, causing intense itching and skin irritation. It is distinct from head lice or pubic lice.

Use this code when documentation clearly indicates a diagnosis of body lice infestation. This typically involves findings of lice or nits (eggs) on clothing, particularly in seams, and excoriations or rash on the trunk and extremities. It is appropriate for cases where the body, not the scalp or pubic area, is the primary site of infestation.

• Differentiate carefully from pediculosis capitis (head lice) and pediculosis pubis (pubic lice), which have distinct ICD-9-CM codes.
• Ensure documentation specifies "corporis" or "body louse" to support this specific code.
• Consider any associated skin infections (e.g., impetigo from scratching) as secondary diagnoses.
