CS Site-Specific Factor 1
Pleural Effusion
- Note 1: One of the most common symptoms of mesothelioma is a pleural effusion, or an accumulation of fluid between the parietal pleura (the pleura covering the chest wall and diaphragm) and the visceral pleura (the pleura covering the lungs). Record the absence or presence of pleural effusion and specifically, if present, whether the pleural effusion is non-malignant, malignant, or NOS.
- Note 2: If imaging indicates a pleural effusion but pleural fluid cytology is described as negative for malignant cells, assign code 010.
- Note 3: If pleural fluid cytology is described as suspicious/suspicious for mesothelioma, assign code 020.
- Note 4: If pleural fluid cytology is described as atypical/atypical mesothelial cells (not specifically non-malignant or malignant), assign code 030.
