About ICD-9-CM 487.0

The CMS General Equivalence Mappings translate it to 2 ICD-10-CM codes, such as J11.00 (Influenza due to unidentified influenza virus with unspecified type of pneumonia) and J12.9 (Viral pneumonia, unspecified). All of these are approximate matches, so review the record to pick the right one.
