What are the different levels of terms in MedDRA?
The highest or broadest level is System Organ Class (SOC), further divided into High-Level Group Terms (HLGT), High-Level Terms (HLT), Preferred Terms (PT), and finally into the most granular Lowest Level Terms (LLT). [8] In addition, the MedDRA dictionary includes Standardized MedDRA Queries (SMQs).
What is the organization of the MedDRA dictionary?
Organization of the dictionary. The MedDRA dictionary is organized by System Organ Class (SOC), divided into High-Level Group Terms (HLGT), High-Level Terms (HLT), Preferred Terms (PT) and finally into Lowest Level Terms (LLT).
How is MedDRA structured?
The structure of MedDRA is very logical. There are five levels to the MedDRA hierarchy, arranged from very specific to very general. At the most specific level, called “Lowest Level Terms” (LLTs), there are more than 80,000 terms which parallel how information is communicated. These LLTs reflect how an observation might be reported in practice.
What are SMQs in MedDRA?
In addition, the MedDRA dictionary includes Standardized MedDRA Queries (SMQs). SMQs are groupings of terms that relate to a defined medical condition or area of interest. Individual cases are usually coded for data entry at the most specific (LLT) level, and outputs of counts or cases are usually provided at the PT level.
What is MedDRA SOC?

What is updated Meddra?
The updated versions of MedDRA are both a strength of the terminology and one of its greatest challenges. Earlier terminologies were not properly maintained nor were there timely releases of these terminologies to address errors or medical advances. The MedDRA MSSO was designed to address both of these issues. MedDRA is currently provided to subscribers on a semi-annual basis utilizing a rigorous medical and technical review for each change request. MedDRA versioning is an issue since most clinical trials run for extended periods of time (i.e., greater than 6 months) and regulatory reports also cover extended periods of time (e.g., Integrated Safety Summary).
What is Meddra versioning?
The MedDRA MSSO was created to address both of these issues. MedDRA is currently provided to subscribers on a semi-annual basis utilizing a rigorous medical and technical review for each change request. MedDRA versioning is an issue that affects the reporting of spontaneous single case reports and pre-market single case reports. Based on comments the MSSO has received on this issue from users of the terminology, the MSSO is making the following recommendations. These recommendations should not be viewed as official guidelines approved by regulatory authorities, however the MSSO hopes that these recommendations are taken into consideration when regulatory agencies draft guidelines regarding this issue in the future.
What is a MedDRA?
MedDRA is a multi-axial terminology meaning that a Prefer red Term (PT) may be linked to more than one SOC. For example, PT Dyspnoea has a link to both SOC Respiratory, thoracic and mediastinal disorders (its organ system of manifestation) and to SOC Cardiac disorders (because of its connection to heart disease). Each PT is assigned a
What is the purpose of the MedDRA Best Practices document?
The purpose of this MedDRA Best Practices document is to provide the recommendations of the MedDRA Maintenance and Support Services Organization (MSSO) for the implementation and use of MedDRA. Its objective is to promote the accurate and consistent use of MedDRA by users worldwide.
Why was Meddra developed?
MedDRA was developed by an ICH Expert Working Group to address many of the limitations of older adverse event terminologies. In the past, organizations that used these terminologies freely “edited” them (e.g., added custom terms) to suit specific needs and to overcome their limitations. The result was a lack of any real standard terminology in the adverse event reporting regulatory environment at that time. The intent of ICH, in developing MedDRA, was to have a standard, medically rigorous, and well-maintained terminology to facilitate communication.
Can a MedDRA subscriber change the primary SOC assignment?
Yes, any MedDRA Commercial, Non-profit/Non-commercial, or Regulatory subscriber may submit a proposal to change the primary SOC assignment for any given term through the usual Change Request process. In considering a subscriber’s request, the MSSO will carefully review the justification provided along with the already established allocation rules.

Is Meddra more specific than COSTART?
MedDRA is much more specific than legacy dictionaries such as COSTART. With more than 60,000 lowest level terms (LLTs), MedDRA offers many choices for the same and/or similar medical concepts. The dramatic increase in the level of specificity with MedDRA means your coders must be medically knowledgeable in order to fully understand the medical concept or condition described within a reported term and to accurately distinguish among the many like choices that MedDRA offers.
Is MedDRA the same as SOC?
Because MedDRA is so highly specific, there are many LLTs that seemingly describe the same medical concept within the same degree of specificity. However, these equally specific, seemingly similar LLTs are not always grouped into the same preferred term (PT) and/or system organ class (SOC).

Overview
MedDRA hierarchy
The five-level hierarchy provides degrees or levels of super-ordination and subordination. The superordinate term is a broad grouping term applicable to each subordinate descriptor linked to it. Hierarchical levels thus represent vertical links in the terminology.
Hierarchies are an important mechanism for flexible data retrieval and for the clear presentation of data. The five-level structure of this terminology provides options for retrieving data by specifi…
