About MedDRA

Vault Safety supports the Medical Dictionary for Regulatory Activities (MedDRA) to code medical terms for symptoms, disease, indicators, and adverse events.

The MedDRA dictionary defines medical conditions. MedDRA codes are organized by five organizational levels, starting with System Organ Class (SOC). The code begins with the system of the body affected and becomes more specific. The SOC codes are divided into High-Level Group Terms (HLGT), High-Level Terms (HLT), Preferred Terms (PT), and Lowest Level Terms (LLT).

By default, you can code an event using either the LLT or PT code. However, an Admin may configure the MedDRA dictionary to use only PT codes.

The version of the MedDRA dictionary that you can use depends on the active version in your vault at the time of creating the Case. The MedDRA Version field in the Case > Details section shows which version of MedDRA the Case uses.


MedDRA Auto-Code Field

The following image shows the combined MedDRA auto-code field, which combines the reported field and MedDRA term field:

Note MedDRA fields may be named differently, according to your vault's configuration.

Code a MedDRA Term

You can code MedDRA terms automatically or use the MedDRA browser to find a term.

Tip The Non-Primary tag identifies terms that are not under their primary SOC. An asterisk (*) identifies terms that are under their primary SOC.

Auto-Code a MedDRA Term

  1. In the combined reported and MedDRA term field, enter the name of the medical term as it was reported by the source.
    This field may be named Event (Reported) or Name (Reported).
  2. To auto-code the term using the reported text, select Autocode-Button.


The system will search for the reported event within the MedDRA dictionary and any preconfigured MedDRA Synonyms. If a match is found, the MedDRA term and code appear below the field. To clear the term, select Clear Selection.

If the system cannot find a match, you can use the MedDRA Browser to find the term. Results are automatically filtered by the reported term entered in the field.

Successful MedDRA Auto-Code

When you change the reported term with the MedDRA browser, the coded term will also be cleared. The previous coded term will be struck through to indicate that it will be cleared when you save. You can clear the coded MedDRA code and the reported term by selecting Clear Selection.

Modified MedDRA Reported Term

If MedDRA Synonym Candidate Auto-Creation is enabled, when the system cannot find a match in the MedDRA Browser or MedDRA Synonym library, the reported term automatically becomes a synonym candidate. To become available for use, synonym candidates must be activated by administrators. For more information, see Synonym Candidate Auto-Creation.

Browse for a MedDRA Term

You can browse the MedDRA dictionary to find a term.

  1. In the MedDRA field, select Binoculars-Icon.
    The MedDRA Browser window appears.
  2. To browse the MedDRA hierarchy, use the tree in the Terms Hierarchy pane to navigate through the five levels.
    • To filter terms by a level in the hierarchy, select Apply.
      You can apply only one filter at a time. Select a different level to change the filter.
    • To clear the filter, select Remove filter icon next to the filter.
  3. To filter the MedDRA Browser to only show terms that are part of a primary system organ class, select Only Primary SOC.
  4. To code a MedDRA term, select the term, and then select Confirm.

Note There is a 1000 SOC search query limit in the MedDRA browser.

Note When you search for a term in the MedDRA browser, the MedDRA browser will only parse through the terms at the LLT and PT levels. You can navigate the Terms Hierarchy pane for terms at the HLT, HLGT, and SOC levels.

MedDRA Browser

The following image shows the MedDRA Browser:

The following table describes the MedDRA browser columns.

Column Description
LLT Low-level term.
PT Preferred term.
HLT Code High-level term code.
HLGT High-level group term.
SOC System organ class.

Recode a MedDRA Term

The system will warn you to recode a term if its MedDRA version is not in sync with the MedDRA version on the Case. This situation can occur in the following instances:

  • The Case was imported with multiple MedDRA versions.
  • An Inbox Item was created with one active MedDRA version, and the version changed before the Promote to Case action.
  • The MedDRA version on the Case was changed manually.
  • A Follow-Up Case was created with Active MedDRA Version enabled.

Vault Safety’s MedDRA update logic ensures that most terms will not require recoding. However, the following list describes the main types of MedDRA version changes that could lead to the required recoding of terms:

  • Promotions or demotions in the MedDRA hierarchy.
  • An LLT categorized under a different PT.
  • An LLT categorized under a different SOC.
  • A PT categorized under a different SOC.
  • A switched MedDRA code.

For more information, refer to your MedDRA-provided documentation.

When a term needs to be recoded, the Recode-MedDRA-Badge badge will appear next to it in the Adverse Event section of your AER. To recode the term, you can browse for a new term in the MedDRA browser. The term that requires recoding will remain at the top of the MedDRA browser until it is changed.

The following image shows an example of a term that needs to be recoded because its MedDRA version is different from the current MedDRA version on the Case:

Code Multilingual MedDRA Terms

You can auto-code or browse for a term in any non-English MedDRA-supported language.

Note Multilingual MedDRA is only supported in vaults using the central MedDRA dictionary.

Multilingual MedDRA Prerequisite

An administrator must enable the multilingual MedDRA Dictionary in order to access these capabilities.

MedDRA-Supported Languages

The following list includes the languages that are currently supported by the multilingual MedDRA browser.

  • Chinese
  • Czech

Auto-Code a Term in a MedDRA-Supported Language

You can auto-code terms in any non-English MedDRA-supported language.

  1. Go to the multilingual MedDRA-supported field.
  2. From the language dropdown menu (Language-Dropdown-Menu), select a supported language.
  3. In the (Reported) field, enter the adverse event in the language it was reported in.
  4. Select Auto-code.


The system searches for the reported term within the MedDRA dictionary in the selected language. If a match is found, the MedDRA term and code appear below the field. On an Inbox Item, the MedDRA term and code appear in the local language specified in the Localization field. If you left the English field blank, the system automatically populates the English MedDRA translation of the adverse event.

Successful Multilingual MedDRA Auto-Code

If the system cannot find a match, you can use the multilingual MedDRA browser to find the term.

Auto-Code a Term in a Non-Supported Language

  1. Go to the multilingual MedDRA-supported field.
  2. Enter the term in the native language in the field.
  3. From the language dropdown menu (Language-Dropdown-Menu), select a non-supported language.

    Note Auto-code is disabled since this is a non-supported language. You must manually fill in the English translation to enable auto-code.

  4. Enter the English translation of the term in the Event as reported in English field and select Auto-code.


The system searches for the reported term within the MedDRA dictionary. If a match is found, the MedDRA term and code appear below the field.

Successful Non-Supported Language Auto-Code

Use the Multilingual MedDRA Browser

When you select a MedDRA-supported language, you can search for terms in English and in the selected language in the multilingual MedDRA browser.

The capabilities in the MedDRA browser for Japanese are different from other non-English MedDRA-supported languages. See Use the MedDRA browser for Japanese Terms for more detail.

  1. Go to the multilingual MedDRA-supported field.
  2. Select a MedDRA-supported language from the language dropdown menu (Language-Dropdown-Menu).
  3. Select Binoculars-Icon.
    The MedDRA Browser appears and displays English terms by default.
  4. To change the MedDRA Browser language, select MedDRA-Browser-Menu-Button, and then select the preferred language.
    Multilingual MedDRA Browser Menu
    The MedDRA Browser now displays terms in the supported language.
    Multilingual MedDRA Browser
  5. To code a MedDRA term, select the term, and then select Confirm.
    If you select a term and then toggle between languages, the equivalent term will be auto-selected in the other language.

Use the MedDRA Browser for Japanese terms

The MedDRA Browser works similarly for Japanese terms. The difference is that the MedDRA Japanese dictionary has its own version for Japanese terms.

If the MedDRA control language is set to Japanese, the Only Current Terms checkbox is automatically selected on the MedDRA browser. This means only current Japanese MedDRA terms are displayed in the browser by default. If the MedDRA control language is not set to Japanese, this checkbox does not appear.

Only Current Terms Checkbox Selected in Japanese MedDRA Browser

You can unselect the Only Current Terms checkbox to display both current and non-current Japanese MedDRA terms. The Non-Current-Tag tag appears next to non-current LLT terms. However, if you select a non-current Japanese term, the MedDRA browser prevents you from coding the term by disabling the Confirm-Button button.

Note The browser only displays current terms in the MedDRA dictionary regardless of the term’s Japanese MedDRA version. Terms that are tagged with the non-current tag indicate that the term is non-current in the Japanese currency (i.e. the term is current in English but non-current in Japanese).
