Kentucky's Any Willing Provider Law

Most states let health insurers close their networks for almost any business reason. Kentucky is one of the few that took a different path for all types of providers. Since 1998, Kentucky law has told health insurers they may not discriminate against a willing provider in their coverage area, and it named the state Medicaid program in the same sentence. For a Kentucky clinician told "the panel is closed," that statute changes the conversation, though it has limits that matter just as much.

What does KRS 304.17A-270 say?

The full text: "A health insurer shall not discriminate against any provider who is located within the geographic coverage area of the health benefit plan and who is willing to meet the terms and conditions for participation established by the health insurer, including the Kentucky state Medicaid program and Medicaid partnerships." It took effect April 10, 1998 (1998 Ky. Acts ch. 496, sec. 13).

Three conditions are built into that sentence:

• Location. The provider must be within the plan's geographic coverage area.
• Willingness. The provider must be willing to meet the terms and conditions for participation.
• The insurer's terms. Those terms are "established by the health insurer," which includes its payment rates and credentialing standards.

Chiropractors have their own statute. A health benefit plan that includes chiropractic benefits must "Permit any licensed chiropractor who agrees to abide by the terms, conditions, reimbursement rates, and standards of quality of the health benefit plan to serve as a participating primary chiropractic provider" (KRS 304.17A-171(2)).

Did the Supreme Court uphold it?

Yes. In Kentucky Association of Health Plans, Inc. v. Miller, 538 U.S. 329, decided April 2, 2003, a unanimous Court in an opinion by Justice Scalia held that both Kentucky laws, 304.17A-270 and the chiropractic provision, are laws "which regulate insurance" and are saved from preemption under ERISA's savings clause. The insurers had argued the laws were not specifically directed at the insurance industry and did not regulate an insurance practice. The Court rejected both points, reasoning that by expanding the number of providers from whom an insured may receive services, the laws alter the scope of permissible bargains between insurers and insureds.

The Court also noted a limit in the opinion's first footnote: Kentucky's law "reaches only those employee benefit plans 'not exempt from state regulation by ERISA.'" Self-funded employer plans are generally exempt from state insurance law, so the statute is a tool for insured coverage and Medicaid, not for a self-funded plan, even one administered by a familiar carrier. See self-funded employer plans and network access.

Are there limits on what the law does?

• It does not set rates. A provider must accept the insurer's terms. A dispute over price is not a willing provider dispute.
• It does not bypass credentialing. Insurers still apply credentialing standards. A denial for an unresolved malpractice issue or an expired document is a credentialing problem to correct, not discrimination.
• It does not reach Medicare Advantage. Federal law supersedes state laws relating to inclusion or treatment of providers in MA, as CMS's Medicare Managed Care Manual notes (Chapter 6, Section 10).
• It does not reach self-funded ERISA plans, per Miller's footnote.

Which companion rules help Kentucky applicants?

Objective standards and open applications. Insurers "shall establish relevant, objective standards for initial consideration of providers," may not use criteria that avoid high-risk populations by excluding providers based on location or because they treat high-risk patients, and must solicit and act on applications "in a fair and systematic manner." That includes letting providers apply "at any time during the year" or, if the insurer does not run continuous enrollment, holding an enrollment period at least annually publicized at least 30 days in advance, and "Making criteria for provider participation in the plan available to all applicants" (KRS 304.17A-525(1) and (2)). KRS 304.17A-565 directs the commissioner of insurance to enforce KRS 304.17A-500 to 304.17A-570, which includes 304.17A-525.

A 45-day credentialing answer. "An insurer issuing a managed care plan shall notify an applicant of its determination regarding a properly submitted application for credentialing within forty-five (45) days of receipt of an application containing all information required by the most recent version of the Council for Affordable Quality Healthcare (CAQH) credentialing form" (KRS 304.17A-576(1)). The clock does not run for events beyond the insurer's control (576(2)). After credentialing, once the applicant signs a contract, the insurer pays for services rendered during the credentialing process under participating provider procedures (576(3)). If credentialing is denied, the insurer reimburses as out of network when the member's plan has out-of-network benefits (576(4)).

Medicaid contract terms. UnitedHealthcare's State and Federal Regulatory Addendum (revised 9/2026) restates Kentucky Medicaid contract terms: credentialing within 30 days unless other law requires otherwise, a contract within 30 calendar days of credentialing, and claims eligible for payment from the credentialing application date. The same text says the plan "is not required to contract with a Provider if the Contractor and provider are unable to agree on the terms and conditions for participation," which is the willing-provider condition from the other side.

How should a Kentucky provider respond to a closed-panel letter?

1. Identify the coverage. Insured commercial, Medicaid, Medicare Advantage or self-funded. The statute applies to the first two.
2. Ask for the participation terms and criteria the insurer must make available under 304.17A-525(2)(b).
3. State your willingness in writing to meet those terms, including the offered rates, and confirm you are in the coverage area.
4. Cure any credentialing gaps and resubmit a complete CAQH-based application to start the 45-day clock.
5. Ask the insurer to reconsider, citing KRS 304.17A-270. If it does not, the Kentucky Department of Insurance or, for Medicaid, the Department for Medicaid Services is the place to raise it.

The letters go out under your name. Whether a refusal is unlawful discrimination under the statute is a legal question for a Kentucky healthcare attorney; we do not give that opinion.

Where we fit

We research, prepare and organize; we are not a law firm. A Network Rejection Review ($249, credited toward a dispute) confirms which coverage the insurer offered and whether 304.17A-270 applies. A Payer Network Dispute ($799 per payer, $1,999 for three) prepares the terms request, the willingness letter, the corrected application and any regulator complaint draft for you to sign and send. We track the 45-day clock and every reply. A contract or credentialing approval carries a flat win fee of $1,500. Compare other states on our Kentucky page and in any willing provider laws.
