Kentucky Assn. of Health Plans, Inc. v. Miller
The Court ruled that Kentucky's "Any Willing Provider" laws, which bar health insurers from excluding doctors and chiropractors willing to meet network terms, survive a federal law that otherwise wipes out state rules touching employee benefit plans.
In doing so, the Court scrapped its old three-factor test for deciding which state insurance laws survive, replacing it with a simpler two-part rule, a change that reshapes how courts nationwide decide whether state insurance regulations can coexist with federal benefits law.
How it got here: A federal trial court ruled the Kentucky laws were saved from preemption; the Sixth Circuit affirmed; the HMOs asked the Supreme Court to review that ruling.
The Case in Depth
What happened
Kentucky passed "Any Willing Provider" laws requiring health insurers to let any qualified, willing doctor or chiropractor join their networks on the same terms as other providers. Several HMOs and a Kentucky HMO association sued Kentucky's insurance commissioner, arguing these laws interfered with their networks of hand-picked providers who offered discounted rates in exchange for guaranteed patient volume, and that a federal law governing employee benefit plans wiped out the state laws.
The question before the Court
Could Kentucky force health insurers to accept any willing doctor or chiropractor into their networks, or did a federal law protecting employee benefit plans get in the way?
Why it matters
Health insurers and HMOs operating in Kentucky, and likely other states with similar laws, must keep their provider networks open to any willing, qualified doctor or chiropractor rather than limiting networks to get volume discounts. The new two-part legal test will guide future disputes nationwide over which state insurance laws survive federal preemption.
What changes now
This is a final merits ruling, not a remand for further factual proceedings; the Sixth Circuit's judgment upholding Kentucky's provider laws stands. Going forward, lower courts nationwide must apply the Court's new two-part test — specific direction at insurers plus a substantial effect on risk pooling — rather than the old three-factor approach when deciding whether other state insurance laws survive ERISA preemption.
What this does not decide
The Court did not decide whether state laws must control the actual terms of insurance policies to be saved from preemption, and it left open how far its new test reaches for laws with only minimal effects on risk pooling or laws applying to entities beyond traditional insurers.
How the Court got there
The legal reasoning, step by step
- The Court had to decide whether Kentucky's provider laws fell within ERISA's saving clause, which protects state laws that 'regulate insurance' from being wiped out by ERISA's broad preemption of laws touching employee benefit plans.
- The Court held that a state law is 'specifically directed toward' the insurance industry, satisfying the first part of the saving-clause test, so long as it imposes obligations on insurers themselves, even if the law also affects outside parties like doctors who deal with those insurers.
- The Court found the provider laws met this requirement because they placed obligations only on 'health insurers' and 'health benefit plans,' not directly on doctors or chiropractors, even though those providers were also affected.
- The Court then rejected the three-factor McCarran-Ferguson test its earlier cases had used to check whether a law regulates insurance, concluding that test was developed for judging private conduct, not state laws, and had produced confusing, inconsistent results.
- In its place, the Court adopted a two-part rule: a state law regulates insurance under the saving clause only if it is specifically directed at the insurance industry and substantially affects the risk-pooling arrangement between insurer and insured.
- Applying this new rule, the Court found that by forcing insurers to open their networks to more providers, Kentucky's laws changed the bargain insurers could offer policyholders, substantially affecting the risk-pooling arrangement and satisfying both parts of the test.
