Pediculosis due to Pediculus humanus capitis

This code represents an infestation of the scalp by the human head louse, Pediculus humanus capitis. This parasitic condition, commonly known as head lice, primarily affects the hair and scalp, causing pruritus and irritation.

Use this code when documentation clearly indicates a diagnosis of head lice. This diagnosis is typically made through visual identification of live lice or nits (louse eggs) on the hair shafts or scalp. It is appropriate for both initial and subsequent encounters for this condition.

• Differentiate from other forms of pediculosis; this code is specific to head lice.
• Ensure documentation specifies the anatomical site (head/scalp) to support this specific code.
• Consider co-occurring conditions such as secondary skin infections (e.g., impetigo) that may result from scratching, and code them separately.
