About ICD-9-CM 577.0
577.0 is an ICD-9-CM diagnosis code for acute pancreatitis. 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 K85.90 (Acute pancreatitis without necrosis or infection, unspecified), K85.91 (Acute pancreatitis with uninfected necrosis, unspecified) and K85.92 (Acute pancreatitis with infected necrosis, unspecified). All of these are approximate matches, so review the record to pick the right one.
