Cloudbyz Safety & Pharmacovigilance, built natively on Salesforce Agentforce, adds an AI coding copilot that turns verbatim symptom text into standard MedDRA terminology — pulling every hierarchy level directly from the dictionary database, never generating one.
Medical coding sits at a deceptively simple-looking junction in pharmacovigilance: a patient or investigator describes something in plain, often imprecise language — "upset stomach," "felt dizzy," "couldn't breathe right" — and a coder has to translate that verbatim text into the correct standardized MedDRA term, at the correct level of the hierarchy, consistent with how similar terms have been coded elsewhere in the same study and across the wider safety database.
Done well, this is what makes aggregate safety data usable — for signal detection, for regulatory submission, for cross-study comparison. Done inconsistently, even by well-trained coders working independently, the same verbatim term can end up coded differently across cases, quietly degrading the very data quality that pharmacovigilance depends on. And because coding volume scales with case volume, the pressure on coders to move quickly makes that inconsistency risk worse, not better, exactly when case counts spike.
The obvious next question — can AI just do the coding — comes with an equally obvious risk. A language model that generates MedDRA terms directly, from its own training data, can produce something that sounds plausible and is not, in fact, a real term at the correct hierarchy level in the current dictionary version. In safety coding, a fabricated or subtly wrong code is not a minor error; it is a data integrity problem with regulatory consequences.
This is the exact problem the Medical Coding Assistant is designed to solve — by architecture, not just by prompt.
The Medical Coding Assistant is a MedDRA coding copilot built into Cloudbyz Safety & Pharmacovigilance, powered by Salesforce Agentforce. It takes verbatim symptom text and translates it into standard dictionary terminology — but it does so by retrieving the actual MedDRA hierarchy from the underlying database for every recommendation, rather than generating terms from a language model's own knowledge.
That distinction is the core design commitment behind the agent: it cannot guess a code. Every term, and every level of the hierarchy above it, is pulled directly from the master dictionary. The agent's role is to search, retrieve, explain, and recommend — the coder's role is to confirm. Final codes are saved to the record only on explicit human confirmation, keeping the coder in control of every entry that becomes part of the safety database.
The Medical Coding Assistant is built for the people directly responsible for safety data quality:
The agent takes plain, everyday verbatim text — "upset stomach," for example — and maps it to the correct standard MedDRA terminology, handling the gap between how patients and investigators actually describe symptoms and how those symptoms need to be represented in a regulated dictionary.
Rather than switching between a coding worklist, a dictionary browser, and a record editor, the coder can run the entire lifecycle conversationally: the agent drafts an event code record, searches the master dictionary, and saves the code on confirmation — all within a single chat-based workflow.
For every recommended term, the agent maps the complete MedDRA hierarchy — System Organ Class down through Preferred Term and Lowest Level Term — by fetching each level directly from the backend dictionary database. The hierarchy is never generated or inferred by the model; it is retrieved, level by level, from the source of truth.
For genuinely tricky or ambiguous verbatim terms, the agent falls back to historical coding decisions and fuzzy search, helping the coder stay consistent with how similar terms have already been coded elsewhere — rather than treating every ambiguous case as if it were being coded for the first time.
Before a coder approves any recommendation, the agent explains the clinical reasoning behind the suggested term — why this verbatim text maps to this specific dictionary entry — giving the coder a real basis for judgment rather than a bare suggestion to accept or reject.
Once a code is confirmed and saved, the agent provides clickable links to the newly created records, keeping the coder's workflow moving directly from decision to verification without a manual search step.
Faster, more consistent coding across the study. By handling dictionary search, hierarchy retrieval, and precedent lookup in one conversational flow, the agent reduces the time each coding decision takes while improving consistency across coders and across cases.
A hard architectural guarantee against invented codes. Because the agent retrieves rather than generates the MedDRA hierarchy, there is no path by which it can produce a code or hierarchy level that does not actually exist in the dictionary. This is not a policy or a prompt instruction — it is a structural guarantee that protects the integrity of safety data at its source.
Better data quality for analysis and submission. Consistent, precedent-aware coding directly improves the reliability of aggregate safety analysis, signal detection, and regulatory submission data — the downstream uses that depend entirely on coding quality upstream.
Confidence through explanation and explicit sign-off. Every recommendation comes with clinical reasoning, and every code is saved only after the coder confirms it — preserving full human accountability for every entry in the safety database, with the agent as copilot rather than decision-maker.
As part of Cloudbyz Safety & Pharmacovigilance, the Medical Coding Assistant operates on the same native Salesforce architecture as Cloudbyz's broader safety product line, including VigiCheck and VigiAggr. Dictionary lookups and hierarchy retrieval happen directly against the underlying MedDRA database already integrated into the platform — with no separate coding tool, no duplicate data entry, and no disconnect between where a case lives and where it gets coded.
Medical coding has always required both linguistic judgment — understanding what a patient actually meant — and dictionary precision — representing that meaning correctly within a regulated terminology. The Medical Coding Assistant brings AI to the first part of that equation while refusing to compromise on the second: every hierarchy level is retrieved from the source dictionary, every code is confirmed by a human coder, and every recommendation comes with the reasoning to back it up.
