Definition

The most granular level in the MedDRA hierarchy, representing verbatim terms, synonyms, and lexical variants that link to a single Preferred Term.

Example

The verbatim 'feeling faint' might map to LLT 'Feeling faint' which links to PT 'Presyncope.' The verbatim is preserved while standardized coding is achieved.

Common mistakes

Always selecting the first LLT match without reviewing the linked PT for clinical appropriateness.

Inspector question

When coding a complex verbatim, how does your team decide which LLT/PT combination best represents the reporter's intent?
