When AI Lies in Healthcare, You’re on the Hook

In healthcare, truth isn’t a nice-to-have — it’s the foundation of everything.  A diagnosis, patient symptoms, a lab result, medical necessity documentation, or a prior authorization request — each depends on precise, verifiable documentation. 

“Mostly right” doesn’t cut it when the cost of being wrong is a denied claim, an audit, or worse.

Yet, that’s exactly what’s creeping into the system through generative AI tools that promise to “save time” by automatically writing notes, justifications, or prior authorization letters.

The Hallucination Problem

Generative AI systems don’t know facts. They generate statistically likely text based on patterns.  When these models are asked to produce clinical documentation—especially highly specific, patient-level medical necessity narratives—they’ll confidently fabricate details if the data isn’t explicitly provided. This isn’t a malfunction. It’s how they’re designed.

It’s like hiring a fast-talking science fiction writer to write your documentation: sounds good, until the payer or the patient calls your bluff.  Generative AI predicts language, not truth.

In healthcare, that’s not innovation. That’s legal exposure, audit risk, and even patient harm.

Cellarian’s Algorithm: No Guesswork, No Hallucinations

Cellarian was built for truth, not creativity, by seasoned physician experts with decades of experience in patient care.

Our algorithm doesn’t “fill in the blanks” or “predict” anything — it automates documentation that already exists in your workflow, tying together patient-specific data, published payer-specific guidelines, and medical policy logic to produce compliant documentation automatically. 

Every order, every diagnosis, every prior authorization justification is derived directly from verifiable data and payer guidance — not from linguistic probability.

Real Automation, Real Defensibility

With Cellarian:

• Medical necessity documentation is generated automatically from actual patient data, provider lab orders, and results.

• Prior authorizations clearly describe the patient-specific medical necessity justification that aligns with policy requirements.

• Audit exposure and recoupment risks are reduced because every document was created from real patient and provider information

No creativity. Just clear and efficient documentation designed to support reimbursement and compliance. 

Accuracy is the bedrock of every order.

You wouldn’t accept a “mostly accurate” lab test — so why accept “mostly accurate” documentation?

When it comes to patient records, payer policies, and compliance, even a little bit of lying is too much.

Cellarian ensures your documentation — from medical necessity to prior auths — is accurate, compliant, and fully defensible.

Because in healthcare, the truth isn’t negotiable.
