Pediculosis, unspecified

This code represents an infestation of lice where the specific type of louse (e.g., head, body, pubic) is not documented. It indicates the presence of pediculosis without further specification of the affected body region or the species of louse.

Use this code when the medical record clearly states "pediculosis" but does not provide additional detail regarding the anatomical site of the infestation. This is appropriate when the physician's documentation is generalized or when the specific type of louse has not been determined.

• Avoid using this code if the documentation specifies the type of pediculosis (e.g., Pediculosis capitis, Pediculosis corporis).
• Review the entire medical record for any mention of the affected body area before assigning this unspecified code.
• This code should be used as a last resort when more specific codes (B85.0, B85.1, B85.3) cannot be supported by the documentation.
