Data Changes

Medi-Span Data Added
A more comprehensive Medi-Span (MDDB) data set is now included in RxNorm.

Changes to MDDB data include the CODE field values. Before the September release, RxNorm used the GPPC-5 as the MDDB CODE field value for TTY = CD. GPPC-5 contains the first 5 characters of a GPPC (Generic Product Packaging Code).

With the September release and onward, the MDDB CODE field value for TTY = CD, BD, MTH_RXN_BD, and MTH_RXN_CD is the Medi-Span Drug Descriptor Identifier (DDID) from MDDB’s Drug Name File MF2NAME. The OID full name is MDDID (Medi-Span Drug Descriptor ID). For TTY = IN, the Ingredient Drug ID from MDDB’s MF2IDRG file is used as the CODE field value. Also, RxNorm no longer includes GPPC-5. RxNorm now represents the full GPPC as an attribute in RXNSAT.

Here is the new MDDB data included in the September release:
