The Fairfax Healthcare Choice

Fairfax County Medicare beneficiaries face a fundamental choice: Inova Health System or Kaiser Permanente. While both systems maintain strong presences across Northern Virginia, Medicare Advantage plan networks often favor one system over the other—or require you to choose Kaiser's fully integrated model. Understanding the differences between these two dominant healthcare systems is essential for making an informed decision about your Medicare Advantage coverage.

⚠️ Why This Decision Matters

Your Medicare Advantage plan choice determines which Fairfax hospital system you can access at in-network rates. Kaiser Permanente operates as a closed network—you can only see Kaiser doctors and use Kaiser facilities (except emergencies). Inova-based plans offer broader access but may have network restrictions. Choosing the wrong plan could mean starting over with new doctors or paying higher out-of-pocket costs.

⚠️ Critical Decision Point

You cannot mix Inova and Kaiser. Kaiser Medicare Advantage plans are a closed system—you can only see Kaiser doctors and use Kaiser facilities (except emergencies). Inova-based plans (UnitedHealthcare, Humana, Aetna, etc.) allow you to use Inova hospitals and independent physicians, but not Kaiser facilities. This is a binary choice: Kaiser integrated model OR Inova traditional network model.
