About the D19 Code Range
The ICD-10 code D19 and its subcategories classify benign tumors originating from mesothelial tissue, which lines body cavities. These codes are used to document noncancerous growths in specific locations such as the pleura, peritoneum, and pericardium, or when the site is not specified.
The code D19.0 covers benign neoplasms of the mesothelial tissue in the pleura, also called pleural fibroma or neoplasm of parietal or visceral pleura. For tumors in the peritoneum, D19.1 applies and is synonymous with terms like peritoneal cystic mesothelioma. If the benign growth occurs in other sites like the pericardium, D19.7 is the correct code, covering terms such as benign mesothelioma of pericardium. When the location of the mesothelial tumor is not specified, D19.9 is used, which refers broadly to a benign tumor of mesothelial tissue. These ICD-10 codes help healthcare providers accurately classify and report benign mesothelial tumors for proper diagnosis and treatment planning.
