Chronic pulmonary blastomycosis

This code represents a persistent fungal infection of the lungs caused by Blastomyces dermatitidis. It is characterized by chronic inflammation and granuloma formation within the pulmonary tissue, often leading to respiratory symptoms. The condition is distinguished from acute forms by its prolonged duration and indolent course.

Use this code for patients diagnosed with a long-standing blastomycosis infection primarily affecting the lungs. Documentation should clearly indicate the chronic nature of the infection, often supported by imaging findings (e.g., cavitary lesions, infiltrates) and mycological studies (culture, histopathology) confirming Blastomyces dermatitidis.

• Ensure documentation explicitly states "chronic" pulmonary blastomycosis to differentiate from acute or unspecified forms.
• Consider co-reporting with codes for associated respiratory symptoms (e.g., cough, dyspnea) or complications if documented.
• Do not confuse with other fungal lung infections; confirm the specific causative organism is Blastomyces dermatitidis.
