AHFS Supplemental File
The American Hospital Formulary Service (AHFS) publishes the AHFS Pharmacologic-Therapeutic Classification codes used throughout the health care industry as means for drug classification.
In 2004, the American Society of Health-System Pharmacists (ASHP) expanded the AHFS codes from six to eight digits, enabling the use of more specific sub-groupings of certain drugs along therapeutic and pharmacologic lines.
The AHFS Supplemental File provides links between these eight-digit codes and Medi-Span’s Generic Product Identifier (GPI) and the National Drug Code with the AHFS code description.
The AHFS Supplemental File is the only Wolters Kluwer Health data source for AHFS Code descriptions.
