C45.9 is a billable ICD code used to specify a diagnosis of mesothelioma, unspecified. A 'billable code' is detailed enough to be used to specify a medical diagnosis.


The ICD code C45 is used to code Mesothelioma

Mesothelioma (or, more precisely, malignant mesothelioma) is a rare form of cancer that develops from cells of the mesothelium, the protective lining that covers many of the internal organs of the body. Mesothelioma is most commonly caused by exposure to asbestos. The most common anatomical site for mesothelioma is the pleura (the outer lining of the lungs and internal chest wall), but it can also arise in the peritoneum (the lining of the abdominal cavity), the pericardium (the sac that surrounds the heart), or the tunica vaginalis (a sac that surrounds the testis).

This is the official approximate match mapping between ICD9 and ICD10, as provided by the General Equivalency mapping crosswalk. This means that while there is no exact mapping between this ICD10 code C45.9 and a single ICD9 code, 199.1 is an approximate match for comparison and conversion purposes.
