About ICD-9-CM 511.89
511.89 is an ICD-9-CM diagnosis code for other specified forms of effusion, except tuberculous. ICD-9-CM was retired for U.S. claims on October 1, 2015, when ICD-10-CM took over.
The CMS General Equivalence Mappings translate it to 3 ICD-10-CM codes, such as J90 (Pleural effusion, not elsewhere classified), J94.2 (Hemothorax) and J94.8 (Other specified pleural conditions). All of these are approximate matches, so review the record to pick the right one.
