Turn free text into codes inside your EDC
Datacapt Medical Coding maps the free-text answers collected in your eCRF to standardized MedDRA and WHODrug terms. Upload your dictionaries once, declare which items to code, and let coders work from a dedicated queue with a complete audit trail. No export, no external tool, no re-import.

Upload. Map. Code.
Without Leaving Your EDC.
Three steps from free text to coded data
Upload your dictionaries once, use them in every study
Version and language read from the package, no manual entry
Several versions active at once, for studies that span dictionary releases
Deprecate a version to stop offering it in new mappings; codes already assigned never change
One dictionary per language and version, with a status that tells you when it is ready
Declare what gets coded, and against which dictionary
Works on free-text questions, including items inside repeated measures
Supporting items of any type from the same subsection, shown to the coder and never coded
Retroactive: answers already collected join the coder’s queue, even on a study running for years
eCRF changes flagged on the mapping: broken in red, modified in yellow, moved items unaffected
A queue built for coders, no eCRF access required
One tab per mapping, with an Uncoded working queue and an All view
Verbatim, code, status, subject and one column per supporting item, with verbatim and code pinned while you scroll
A side panel opens the full text and its supporting items in one click
Coders see verbatims only and never open the eCRF
Find the right LLT in a few keystrokes
Full path shown before you apply: LLT, PT, HLT, HLGT and SOC
Terms on several branches show every path, primary in blue; the path you pick is the path stored
Several codes per verbatim, one per medical concept, each with an optional interpretation note
Apply code stores the path, the dictionary version, the mapping, the coder and the time
Every dictionary, mapping and code, traced
Dictionaries: Access to view, Edit to upload, deprecate or delete
Mappings: Access to view, Edit to create or delete, with a warning before any deletion
Coder: Access to read verbatims, Edit to search a dictionary and assign codes
Safeguards: a dictionary used by a mapping cannot be deleted, only deprecated

Medical coding translates the free-text answers collected in the eCRF, the verbatims, into the standardized terms of a medical dictionary: MedDRA for adverse events and medical history, WHODrug for medications. The same event reported in different words then maps to a single code, which keeps safety reporting and analysis consistent.
Yes. Dictionaries, mappings and the coder workspace live inside Datacapt. You upload the dictionary once, declare which eCRF items to code, and coders work from their own queue without opening the eCRF. No export, no external tool, no re-import.
Datacapt supports MedDRA and WHODrug, in any language and version. You need your own dictionary licence: Datacapt ships no dictionary content. Several versions can stay active at once, and you can deprecate a version without changing the codes already assigned.
Yes. Each mapping ties one free-text item to one dictionary, so adverse events point to MedDRA and concomitant medications to WHODrug in the same study. Coders get one tab per mapping.
Yes. Mappings are retroactive. The moment you create one, every answer already collected on that item joins the coder queue, even on a study that has been open for years.
You upload the new version next to the current one. Several versions stay active at the same time, and deprecating an old version keeps it out of new mappings without touching any code already assigned.
No. Coders work from the study's Medical coding page: verbatim, code, status, subject and the supporting items declared in the mapping. They never open the eCRF and they never change collected data.
Yes. A coder applies one code per medical concept, each with an optional interpretation note. Datacapt stores the full path (LLT, PT, HLT, HLGT, SOC) with the dictionary version, the mapping, the coder and the timestamp.
Yes. Datacapt Medical Coding runs on the same validated platform as the EDC, in line with 21 CFR Part 11, ICH-GCP and GDPR. Every dictionary upload, mapping and code assignment is traced with who did it and when. Validation documentation is available on request.
