Histoplasmosis, unspecified

This code represents a fungal infection caused by Histoplasma capsulatum where the specific type or manifestation of the disease is not documented. Histoplasmosis can affect various organ systems, most commonly the lungs, but can also disseminate to other parts of the body, particularly in immunocompromised individuals.

Use this code when the medical record confirms a diagnosis of histoplasmosis, but the physician's documentation does not specify the form (e.g., pulmonary, disseminated, ocular). This code is appropriate when the provider simply states "histoplasmosis" without further detail.

• Avoid using this code if more specific documentation is available; query the provider for clarification on the type of histoplasmosis.
• Consider codes from categories B39.0-B39.8 if the specific form of histoplasmosis (e.g., acute pulmonary, chronic pulmonary, disseminated) is documented.
• Always code any associated manifestations or complications of histoplasmosis, such as pneumonia or meningitis, in addition to the histoplasmosis code.
