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.
This product is produced and delivered to customers on a daily or weekly
