Pulmonary cryptococcosis

This code identifies a fungal infection of the lungs caused by Cryptococcus neoformans or Cryptococcus gattii. It can manifest as pneumonia, nodules, or masses within the pulmonary parenchyma, often presenting with cough, dyspnea, and chest pain. The infection may be localized to the lungs or be part of disseminated cryptococcosis.

Apply this code when documentation confirms a diagnosis of cryptococcal infection specifically affecting the lungs. This includes cases identified through culture, histopathology, or antigen testing from respiratory specimens (e.g., sputum, bronchoalveolar lavage). It is appropriate for both primary pulmonary involvement and pulmonary manifestations of systemic cryptococcosis.

• Ensure documentation clearly specifies pulmonary involvement; if the infection is disseminated, additional codes for other affected sites may be necessary.
• Distinguish from other fungal pneumonias; look for specific mention of Cryptococcus.
• If the patient is immunocompromised (e.g., HIV positive), code the underlying immunocompromised state first, followed by this code.
