On June 3, the National Center for Health Statistics (NCHS) posted its ICD-9-CM index addenda and ICD-9-CM tabular addenda. As part of the 2010 addenda, NCHS has expanded code category 488 to add two new codes:
- 488.0 (Influenza due to identified avian influenza virus)
- 488.1 (Influenza due to identified novel H1N1 influenza virus)
In addition, coders and others can reference an ICD-9-CM code conversion table at www.cdc.gov/nchs/datawh/ftpserv/ftpicd9/icdcnv10.pdf.
On June 10, CMS posted the new, revised, and invalid diagnosis and procedure codes on its Web site.
Each of these changes, many of which pertain to new E codes, will take effect October 1.
