Supreme Court upholds any-willing-provider laws

The Supreme Court has upheld two 1994 Kentucky laws requiring HMOs to open their networks to any health care provider willing to accept the insurer’s reimbursement rates and contract terms.

About half of U.S. states have similar laws, known as "any-willing-provider" statutes.

Lawyers for a group of Kentucky HMOs and a managed-care trade association argued the laws improperly regulated employee benefits, a duty reserved for Congress. However, the justices ruled unanimously that the state was within its rights to regulate insurance companies operating in the state.
