About ICD-9-CM 488.09

488.09 is an ICD-9-CM diagnosis code for influenza due to identified avian influenza virus with other manifestations. 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 2 ICD-10-CM codes, such as J09.X3 (Influenza due to identified novel influenza A virus with gastrointestinal manifestations) and J09.X9 (Influenza due to identified novel influenza A virus with other manifestations). All of these are approximate matches, so review the record to pick the right one.
