About ICD-9-CM 998.13
998.13 is an ICD-9-CM diagnosis code for seroma complicating a procedure. 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 31 ICD-10-CM codes, such as D78.33 (Postprocedural seroma of the spleen following a procedure on the spleen), D78.34 (Postprocedural seroma of the spleen following other procedure) and E89.822 (Postprocedural seroma of an endocrine system organ or structure following an endocrine system procedure). All of these are approximate matches, so review the record to pick the right one.
