CMS Pub. 100-02, ch. 15, § 50.1
Definition of Drug or Biological
B3-2049.1
Drugs and biologicals must be determined to meet the statutory definition. Under the statute §1861(t)(1),
payment may be made for a drug or biological only where it is included, or approved for inclusion, in the
latest official edition of the United States Pharmacopoeia National Formulary (USP-NF), the United States
Pharmacopoeia-Drug Information (USD-DI), or the American Dental Association (AOA) Guide to Dental
Therapeutics, except for those drugs and biologicals unfavorably evaluated in the ADA Guide to Dental
Therapeutics. The inclusion of an item in the USP DI does not necessarily mean that the item is a drug or
biological. The USP DI is a database of drug information developed by the U.S. Pharmacopoeia but
maintained by Micromedex, which contains medically accepted uses for generic and brand name drug
products. Inclusion in such reference (or approval by a hospital committee) is a necessary condition for a
product to be considered a drug or biological under the Medicare program, however, it is not enough.
Rather, the product must also meet all other program requirements to be determined to be a drug or
biological. Combination drugs are also included in the definition of drugs if the combination itself or all of
the therapeutic ingredients of the combination are included, or approved for inclusion, in any of the above
drug compendia.
Drugs and biologicals are considered approved for inclusion in a compendium if approved under the
established procedure by the professional organization responsible for revision of the compendium.
