About Chetan Parikh
Chetan Parikh moved from GE chemical engineering into healthcare by design. He built NLP from the ground up at EZDI, exited, kept core research talent, and started RAAPID in 2021 to focus on value based care, risk adjustment, and trustworthy AI. His view: AI must be explainable, grounded in clinical knowledge, and deployed where it saves time and improves accuracy. He invests in university research, ships applied tech fast, and designs teams to learn with customers.

September 22, 2025
Why switch from chemical engineering to healthcare?

It was by design. Engineering gave me a great base, but I wanted work that felt deeply meaningful. Education and healthcare stood out. In 2002 I entered medical transcription, saw the impact of getting the right information to the right person at the right time, and never looked back.
What pulled you from transcription into NLP and AI?

I wanted the deeper meaning inside notes. Around 2008-2009 we set out to understand records automatically and put synoptic, accurate information in front of providers. I did not find tech good enough, so we built our own NLP, formed a team, and launched EZDI.
Explain AI, NLP, and LLMs in simple terms.

AI looks at lots of data and predicts next steps. NLP teaches a system to understand human language and structure. LLMs add huge compute and context, so the model can generate the next word and connect many dots at once.
What is hallucination and why is it risky?

One small wrong assumption can multiply as the model keeps generating. It looks convincing but goes off-path. In healthcare this is unacceptable, so we push explainability and clear evidence.
What do you mean by neuro-symbolic AI?

The neuro is the LLM. The symbolic is a knowledge graph of medical concepts and connections. We ground the LLM in that graph so decisions use real clinical relationships, not just statistics.
How much does neuro-symbolic improve accuracy?

Classic NLP gave about 65-70% out of the box coding accuracy. With neuro-symbolic we see about 92% out of the box on risk adjustment tasks. That is a step change.
What should buyers ask vendors in a crowded market?

Ask if they can implement now at your volume, how pricing and support work, how they prove trustworthiness on your data, and how they defend against RADV risk with evidence and explainability.
How do you recommend testing a solution quickly?

Do a small POC with real charts. We can provision access, receive charts, and show results on the same call. Following CMS guidelines, high accuracy should show up without training on client data.
How does coder work change with this AI?

NLP was assistive. Coders checked everything. Neuro-symbolic becomes augmentative. The system auto adjudicates high confidence codes, shows probability, and coders focus on true judgment calls. Trust builds over time.
Is AI still a durable moat for vendors?

No. AI is an enabler now. Advances arrive in weeks, not years. That is good for buyers. We stay ahead with applied research, domain focus, and fast productization.
How do you invest to stay ahead?

We fund university research and turn it into applied algorithms for risk adjustment, coding, and CDI. Topics include trustworthy AI, neuro-symbolic methods, and both large and small language models.
What solutions are you shipping at RAAPID?

A RADV audit tool built by auditors for auditors, and our neuro-symbolic coding platform that outperforms legacy NLP. The goal is trustworthy automation and fewer manual passes.
How do you handle enterprise privacy and security?

We do not need client data to train models. For large enterprises on Azure, we can deploy inside their own instance behind their firewall, so data never leaves and we do not access it.
What is agentic AI in records review?

We create multiple AI agents with clear personas: top coder on one model, another on a second, an evidence finder, judges, and a compliance auditor. They cross check each other and escalate only the hard cases to a human.
Does agentic AI raise compute cost too much?

Tech cost rises but labor drops. Think excavator vs many shovels. Total cost goes down while accuracy, compliance, and only pass outcomes improve.
Do you still support first pass and second pass reviews?

With old NLP, yes. With agentic, neuro-symbolic AI, we aim for one decisive pass plus targeted human augmentation where agents disagree. It is faster, cheaper, and more defensible.
How do you view date of service vs whole year reviews?

Agents analyze every date of service, but we present the signal once with linked evidence. CMS wants accurate capture and management of true conditions. Looking across the year avoids noise, reduces burnout, and still defends every code.
