Mixed pediculosis infestation

This code signifies a parasitic infestation of the skin and hair by more than one species of lice. It indicates a concurrent presence of different types of Pediculus species, such as head lice (Pediculus humanus capitis), body lice (Pediculus humanus corporis), or pubic lice (Pthirus pubis). The patient presents with symptoms related to multiple louse infestations.

Use this code when documentation clearly indicates the presence of an infestation by two or more distinct types of lice. This typically involves findings of nits or adult lice characteristic of different species on various body parts. Physician documentation explicitly stating "mixed pediculosis" or identifying multiple louse species supports the use of this code.

• Do not use this code if only one type of pediculosis is identified; instead, select the specific code for that single infestation.
• Ensure the medical record specifies the presence of multiple louse species, not just a widespread infestation by a single species.
• Consider sequencing this code as the primary diagnosis if it is the reason for the encounter, or as a secondary diagnosis if it is a co-existing condition being treated.
