Core Concepts

These are the foundational concepts that every clinician, analyst, and healthcare IT professional should understand. They are the "why" behind the systems you use every day.

01 · EHR FUNDAMENTALS
The Universal Healthcare Data Chain
Patient → Encounter → Clinical Event → Data Point. This structure is not a design choice — it is forced by medicine, billing law, and 30 years of regulatory pressure. Understanding it unlocks everything else.

02 · HEALTHCARE POLICY
The $25.9 Billion Law That Built Modern Healthcare IT
The HITECH Act didn’t just pay hospitals to buy software. It restructured how clinical data is created, stored, and shared — and created the fragmented landscape we still navigate today.

03 · FHIR DATA MODEL
Event vs. Request vs. Observation
The three building blocks of clinical data in every modern EHR. A medication order, a lab result, and a vital sign are fundamentally different types of information — and treating them the same breaks everything downstream.

04 · AI IN HEALTHCARE
What’s Actually Working vs. What’s Still Promise
Ambient documentation is real. Autonomous diagnosis is not. A candid, evidence-based assessment of where the healthcare AI line actually is — so you can make better decisions about what to adopt.

What Interoperability Actually Means (And Why It’s Hard)
HL7, FHIR, the 21st Century Cures Act, information blocking rules. The full picture of why healthcare data still doesn’t flow freely despite decades of effort and billions in federal investment.

06 · REVENUE CYCLE
How a Clinical Encounter Becomes a Paid Claim
From the moment a patient is registered to the moment a payer deposits money. Charge capture, coding, claims submission, adjudication, denial management, and the real reason clinical documentation matters beyond care.
