Phthiriasis

This code represents an infestation of the human body by pubic lice, also known as crab lice. These parasitic insects typically infest the pubic hair and surrounding areas, but can also be found in other coarse body hair such as the armpits, eyelashes, and beard. The infestation causes intense itching and irritation.

Use this code when the patient's medical record clearly documents a diagnosis of pubic lice infestation. This diagnosis is typically made through visual identification of the lice or their nits (eggs) on the affected body hair. Documentation should specify the presence of Phthirus pubis.

• Do not confuse with other types of pediculosis (e.g., head lice, body lice), which have distinct codes.
• Ensure documentation specifies "pubic lice" or "crab lice" to support this specific diagnosis.
• Consider any associated symptoms, such as pruritus, which may be coded separately if significant.
