Pulmonary alveolar microlithiasis
ICD-10 J84.02 is a billable code used to indicate a diagnosis of pulmonary alveolar microlithiasis.
Pulmonary alveolar microlithiasis (PAM) is a rare lung disease characterized by the accumulation of microscopic calcium phosphate crystals within the alveoli, leading to respiratory dysfunction. Clinically, patients may present with symptoms such as progressive dyspnea, cough, and chest pain. The disease primarily affects the lung's alveolar spaces, which are crucial for gas exchange. As PAM progresses, it can lead to pulmonary fibrosis, resulting in decreased lung compliance and impaired oxygenation. Diagnosis typically involves imaging studies such as chest X-rays or CT scans, which reveal characteristic bilateral ground-glass opacities and micronodular patterns. A definitive diagnosis may require lung biopsy, where the microliths can be identified histologically. Given its rarity, PAM often poses diagnostic challenges, necessitating a high index of suspicion in patients presenting with unexplained respiratory symptoms. Early recognition and management are essential to mitigate complications and improve patient outcomes.

J84.02 specifically covers pulmonary alveolar microlithiasis, a condition characterized by the accumulation of microliths in the alveoli, leading to respiratory symptoms and potential lung damage.
J84.02 should be used when there is clear evidence of pulmonary alveolar microlithiasis, particularly when imaging and clinical findings support this diagnosis, differentiating it from other interstitial lung diseases.
Documentation should include clinical symptoms, imaging results showing characteristic findings, and any histopathological evidence from lung biopsies confirming the presence of microliths.
