2025 ICD-10-CM code B40.2
(Active) Effective Date: N/A Certain infectious and parasitic diseases - Mycoses 1 Feed
Pulmonary blastomycosis, unspecified.
Medical necessity for diagnostic testing and treatment is established by the signs, symptoms, and confirmed presence of the Blastomyces dermatitidis fungus.
Physicians diagnose pulmonary blastomycosis based on patient history (including travel to endemic areas), physical exam, and symptoms. Lab tests such as blood, urine, and sputum cultures or antibody tests, tissue biopsies, and imaging studies like chest X-rays and CT scans are used for diagnosis. Treatment involves antifungal medication.
In simple words: Blastomycosis is a lung infection caused by a fungus. It's caught by breathing in spores from the environment. This particular code is used when the infection is in the lungs but the doctor hasn't specified whether it's a short-term or long-term infection.
A fungal infection of the lungs caused by inhaling Blastomyces dermatitidis spores, typically found in moist soil and decaying organic matter.This code specifies that the pulmonary blastomycosis is not further categorized as acute or chronic.
Example 1: A patient presents with flu-like symptoms after a camping trip in an endemic area.Lab tests confirm pulmonary blastomycosis, but it is not yet clear if it is acute or chronic. B40.2 is used., A patient with a weakened immune system develops pneumonia with persistent fever, weight loss, and cough. A lung biopsy reveals blastomycosis. Since the chronicity is not specified at the time of diagnosis, B40.2 is used., A chest X-ray performed for an unrelated reason incidentally reveals findings suggestive of pulmonary blastomycosis.Further workup is pending to determine the specific type.B40.2 is appropriate until a more definitive diagnosis is established.
Documentation should include signs and symptoms, patient history (including possible exposure to endemic areas), lab results (cultures, antibody tests, biopsy), and imaging findings.
