"Why can't I just use ChatGPT?" It's a fair question. ChatGPT is powerful. It's free (or cheap). And it can summarize documents. But for medical record review in claims work, general-purpose AI has fundamental limitations.
The context window problem
ChatGPT and similar tools can only process a limited amount of information at once — typically 8,000 to 128,000 tokens depending on the version. Once that limit is reached, earlier context drops out.
Medical records for complex claims often run thousands of pages. A workers' comp claim with 10 years of treatment history doesn't fit in a context window. The AI can't connect a 2019 injury to a 2024 complication if it can't see both at once. Specialized medical AI is built to handle records of any length without losing context.
The "black box" problem
When ChatGPT gives you an answer, where did it come from? Which page? Which sentence?
For defensible claims decisions, you need traceability. Click-to-evidence functionality — where every extracted data point links directly to its source document — isn't optional. It's essential for audits, appeals, and litigation. General-purpose AI doesn't provide this. Specialized platforms do.
The hallucination problem
77% of businesses express concern about AI hallucinations, and 47% of enterprise AI users admitted to making at least one major business decision based on hallucinated content in 2024 (Fullview).
Medical records contain critical details: medication dosages, procedure dates, diagnosis codes. Fabricated information isn't just unhelpful — it's dangerous. Specialized medical AI combines domain-specific training, medical knowledge bases, and entity recognition to minimize hallucinations. General-purpose AI is trained on internet data, including satire and misinformation.
The compliance problem
Sharing sensitive medical data with consumer AI tools raises privacy and regulatory concerns. HIPAA, PIPEDA, and provincial health privacy laws have specific requirements for handling patient information.
Enterprise-grade medical AI platforms are built with these requirements in mind — encryption, access controls, audit trails, and compliance certifications.
The bottom line
ChatGPT is excellent for drafting emails and brainstorming. For medical record analysis that's accurate, traceable, and compliant — you need purpose-built tools.
