Network Access for Chiropractors

Chiropractic is one of the few specialties where insurers publish formal network closures, and also one of the few with its own any willing provider statute in Kentucky. Medicare Advantage plans are measured on chiropractor access in every county. Here is how chiropractors get around a closed network, and where a dispute has real footing.

Chiropractors are told "the network is closed" more formally than most providers. Some insurers publish it. Independence Blue Cross in Pennsylvania, for example, states on its credentialing page that "the chiropractic network is closed to new providers in Pennsylvania and through New Castle County in Delaware," with two exceptions: "when the provider is joining an existing participating group" and when there is a change of control or ownership of a participating practice that complied with its agreement. Seeing it in writing is discouraging. It is also useful, because a published closure usually comes with published exceptions.

What are the usual ways around a closed chiropractic network?

Join a participating practice. The most common exception, and the one IBX lists first. See joining a participating group.
Buy a participating practice. A change of ownership that follows the seller's contract terms on assignment can carry the participation with it. Read the assignment clause before you close.
Practice where the closure does not reach. Closures are often defined by county or service area.
Use the state law that applies to chiropractic. In a few states, that is decisive.

Does any state require plans to accept chiropractors?

Kentucky does. Its statute, quoted by the U.S. Supreme Court in Kentucky Ass'n of Health Plans v. Miller, 538 U.S. 329 (2003), says any "health benefit plan that includes chiropractic benefits shall ... [p]ermit 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 to any person covered by the plan" (Ky. Rev. Stat. 304.17A-171(2)). The Court upheld Kentucky's any willing provider laws against an ERISA preemption challenge, so they apply to insured plans. Self-funded employer plans are outside them. See Kentucky's any willing provider law and Kentucky network access laws.

Elsewhere, look at your state's general rules: broad any willing provider statutes are rare, but credentialing deadlines and fair-opportunity laws are more common. The network access laws index lists what we have verified for each state.

Are Medicare Advantage plans measured on chiropractors?

Yes. "Chiropractor" is one of the provider-specialty types in CMS's network adequacy rule (42 CFR 422.116(b)(1)(iv)). Each Medicare Advantage plan must meet a minimum number and time and distance standards for chiropractors in every county it serves, with at least 90 percent of beneficiaries in metro counties and 85 percent in micro, rural and extreme-access counties within the published limits (422.116(d)(4)). Plans that cannot meet a standard must request an exception, and CMS considers whether current access "is different from the HSD reference and Provider Supply files" (422.116(f)(2)(i)).

A willing, credentialed chiropractor in a county where a plan claims there are not enough available providers is direct evidence against that claim. Our post on Medicare Advantage network adequacy exceptions explains the process.

Does your Medicare enrollment affect plan participation?

It can. Medicare Advantage plans verify "eligibility for payment under Medicare" during credentialing (42 CFR 422.204(b)(2)(i)). Medicare Part B covers a narrow set of chiropractic services: it "pays only for a chiropractor's manual manipulation of the spine to correct a subluxation" when the subluxation has resulted in a neuromusculoskeletal condition for which manipulation is appropriate, and does not pay for X-rays or other diagnostic or therapeutic services furnished or ordered by a chiropractor (42 CFR 410.21(b)). Even so, enrollment status matters to MA credentialing. White Glove Chiropractic explains Medicare enrollment after licensing.

What evidence helps a chiropractic dispute?

The plan's written reason. Medicare Advantage (422.205(a)) and Medicaid managed care (438.12(a)(1)) plans must give one.
A directory check of listed in-network chiropractors near you: who answers, who takes new patients, first available appointment.
Distance from the ZIP codes you serve to the nearest listed chiropractor who is actually taking patients.
What you add: Saturday hours, a language, workers' compensation and auto injury experience, a rural location.

Then ask for a specific remedy: an exception to the closure, an application review, or a single-case agreement for a member who has no in-network option nearby. See how to write a network adequacy letter.

How do we help?

We check whether a closure is published and what its exceptions are, apply your state's rules, run the directory audit, and prepare the letter and evidence. You sign and send it to the plan. We do not represent chiropractors or give legal advice; if a contract assignment in a practice purchase is at issue, have a healthcare attorney review it. Prices are on our pricing page, including the $249 review and the flat $1,500 win fee when a plan offers a contract.

Common questions

Can I get in-network if the chiropractic network is closed?

Often through a published exception, such as joining a participating practice or acquiring one through a change of ownership that follows the contract's assignment terms. Closures are also often limited to certain counties or service areas.

Does any state require insurers to accept chiropractors?

Kentucky requires health benefit plans that include chiropractic benefits to permit any licensed chiropractor who agrees to the plan's terms, rates and quality standards to participate (Ky. Rev. Stat. 304.17A-171(2)). It does not reach self-funded employer plans.

Do Medicare Advantage plans need chiropractors in their networks?

Chiropractor is one of the provider-specialty types CMS measures for Medicare Advantage network adequacy, with minimum numbers and time and distance standards set for each county (42 CFR 422.116).
