Learn how to bulk recode non-current MedDRA-coded terms on Cases following active MedDRA dictionary version updates.
About MedDRA Bulk Recode Cases
When new MedDRA dictionary versions are activated, you can use the MedDRA Bulk Recode tool to update non-current MedDRA-coded terms on Cases.
Available to Business Admins, MedDRA Bulk Recode offers the following capabilities:
- Preview and validate MedDRA code changes before committing them.
- Run bulk recoding in a single action.
- See changes tracked in detail in a Case audit trail and summary report.
Note: When a new MedDRA dictionary version is made active, the system automaticlly recodes MedDRA-coded terms with hierarchy changes.
For details on configuring your Vault for this feature, see Enable MedDRA Bulk Recode Cases.
How Vault Safety Bulk Recodes Cases
Vault Safety can bulk recode non-current MedDRA-coded terms on up to 20,000 Cases at one time. The Case fields that may be recoded include the following:
| Object | Field |
|---|---|
| Case Product > Indication | Indication (LLT) |
| Case Adverse Event | Event (LLT) |
| Case Diagnosis | Name (MedDRA) |
| Case Cause of Death | Cause of Death (LLT) |
| Case Medical History & Concurrent Conditions | Condition/Procedure (LLT) |
| Case Drug History |
|
| Case Test Result | Test Name (LLT) |
Note: Reported Terms are not affected by recoding.
Recode Active Cases
Bulk recoding of non-current MedDRA-coded terms on active Cases and Follow-Up Cases is completed on the same Case version. Active Cases are open Cases in a state prior to any Void, Submitted, or Completed state, such as Data Entry, QC, Medical Review. See more information on lifecycle states.
When MedDRA-coded terms are updated, Expectedness is re-evaluated on the Case. The Case Audit Trail tracks all system changes.
Note: Bulk recoding is applied to Cases locked either manually or by strict case locking.
Recode Approved and Closed Cases
For Approved and Closed Cases with non-current MedDRA-coded terms, the system completes the following actions:
- Creates a Follow-Up Case: The system creates a new version of the Case and imports all relevant information from the initial version. Original Cases in the Approved state remain in that state. Original Cases in the Closed state become Superseded. MedDRA-coded terms on the original Cases are not recoded.
- Recoding: On the Follow-Up Cases, the MedDRA-coded terms are replaced with the new MedDRA codes and terms.
- Updates State to Recoded: When the recoding is complete, the Follow-Up Case state becomes “Recoded”.
- Generates a Summary Report: When the recoding is complete, a downloadable summary report is generated detailing each impacted Case and the action taken.
Note: The system does not re-evaluate Expectedness or Watchlists during bulk recoding of Closed and Approved Cases. Follow your organization’s established process to determine next steps, such as evaluating reporting obligations. Contact Veeva Support for assistance on configuring any required workflows.
Procedure Overview
At a high level, MedDRA bulk recoding involves the following steps:
- Create a Dictionary Bulk Action record.
- Prepare and upload a mapping file of replacement terms and codes.
- Preview the bulk recode.
- Run the bulk recode.
- Download the MedDRA Bulk Recode Summary Report.
Audit Logging
When the bulk recoding runs, all changes are recorded in the applicable Case audit log as “System on behalf of {user}.”
Prerequisites
- You must be a Business Admin with access to the Dictionaries library to bulk recode non-current MedDRA-coded terms.
- Ensure your Vault has the necessary configuration to enable this feature.
Create a Dictionary Bulk Action Record
Dictionary Bulk Action records enable you to upload a MedDRA code mapping file, preview the bulk recode, and run the bulk recode.
- Go to Business Admin > Objects > Dictionaries > MedDRA Dictionary.
- In the Dictionary Bulk Actions section, select Create.
- Complete the fields in the Details section.
- Select Save.
Dictionary Bulk Action Fields
| Field | Description |
|---|---|
| Name | Enter a name for the action, such as "Bulk Recode to MedDRA version [number]". |
| Organization | Select the Organization for which you want to complete the recode. |
| Replacement MedDRA version | Select the MedDRA version with the updated terms and codes. |
| Report Type | Optionally, select a Report Type for the update. Leave this field blank to update Cases from all Report Types. |

Prepare and Upload a Mapping File of Replacement Terms and Codes
To begin MedDRA bulk recoding of non-current terms, you must first upload a mapping file. The file must list each MedDRA LLT code and term that is being replaced, the replacement MedDRA code, and the MedDRA version in which the the replacement code is found.
See the following considerations when preparing the file:
- The file format must be CSV
- The file name must be
mapping.csv - The file must include between 1 and 20,000 rows.
- The column names must appear as shown below and in the following order:
- Coded LLT
- Coded LLT Term
- Replacement LLT Code
- Replacement Version
Note: Please be aware that mapping file columns cannot include commas. If a comma is included in any value, it is read as a separate item. This is a known limitation that will be addressed in a future release.
Mapping CSV Format
The following table describes the columns supported in the mapping.csv file:
| Column | Description |
|---|---|
| Coded LLT | Each row must specify a MedDRA LLT code that is being replaced. The system uses this code to search for Cases impacted by the MedDRA update. |
| Coded LLT Term | Each row must specify the MedDRA LLT term that is being replaced. The term must correspond to the code in the Coded LLT column. |
| Replacement LLT Code | Each row must specify the LLT Code that will replace the code in the Coded LLT column. All Replacement LLT Codes must exist in the MedDRA Dictionary identified in the Replacement Version column of the file. A Replacement LLT Code is considered part of the MedDRA Dictionary if it is found in one of the following fields, based on priority:
|
| Replacement Version | Each row must include the version number of the MedDRA Dictionary with the replacement LLT codes.
Note: A |
