Annex A ( 2022) provides terminologies for categorized adverse event reporting for the medical problem codes. The name and version of the dictionary used to map terms must be provided in a Define.XML ExternalCodeList element (See see Section 2.10, Standards for Data Exchange).
EMDECOD was the Level 3 IMDRF term. Non-standard variables NSVs were used to represent the various coding level variables defined in the dictionary.

Below is the dataset, SUPPEM, The SUPPEM dataset is used to represent the non-standard variables NSVs used for coding the malfunction or event. The parent domain (RDOMAIN) is EM, and IDVAR is EMSEQ. QNAM holds the name of the supplemental qualifier variable being defined. This only shows the data for subject 2029. The data recorded in QVAL applies to the subject’s records, where IDVAR (EMSEQ) equals the value specified in IDVARVAL.
