Contracting Leverage

Summary: Dominant hospitals can threaten insurers with exclusion from their network, forcing acceptance of high prices.

The Problem

When a hospital system controls a large portion of a region's healthcare capacity, it has extraordinary bargaining power over insurance companies.

How It Works

Hospital to Insurer:

"If you add that new cheaper hospital to your network, we'll remove ourselves from your network entirely."

Insurer's dilemma: - Lose the dominant hospital → lose all customers in that region - Keep only the cheap hospital → customers won't buy insurance without access to the major hospital

Result: Insurer accepts the dominant hospital's prices and often excludes cheaper competitors.

This practice is called contracting leverage or network leverage: - It's not explicitly illegal in most states - It's framed as "negotiation" rather than monopolistic behavior - Hospitals argue they're simply choosing their business partners - FTC rarely intervenes in hospital contracts

Real-World Examples

  • Major hospital systems routinely include "anti-steering" clauses
  • "All-or-nothing" contracts force insurers to include all facilities in a system
  • Exclusive dealing arrangements prevent insurers from favoring cheaper alternatives

Impact

This makes it nearly impossible for a new, cheaper hospital to gain market share, because: 1. New hospital offers lower prices 2. Insurer considers adding it to network 3. Dominant hospital threatens to leave 4. Insurer backs down 5. New hospital gets no patients 6. New hospital fails

Is This Different from Other Industries?

Yes. In most industries: - There are many suppliers - Customers can easily switch - Government enforces anti-trust more aggressively

In healthcare: - Few suppliers per region - Customers cannot switch during emergencies - Anti-trust enforcement is weak

Consequences

  • 1.3 - Entry Barriers - New hospitals cannot access insurer networks
  • 1.8 - Nash Equilibrium - System locked in place
  • 1.2 - Insurer Incentives - Why insurers don't fight harder
