Each State's Uniform Medicaid Credentialing Policy

When a Medicaid managed care plan denies or stalls a credentialing application, the yardstick is not only the plan's own policy. Federal rules make the state set the credentialing policy for every plan in its Medicaid program. A denial that departs from the state's policy, or a file that sits past the state's contract deadline, is a different kind of problem from a plan exercising its own judgment, and it has a different audience.

What does federal law require of the state?

Under 42 CFR 438.214(b)(1), "Each State must establish a uniform credentialing and recredentialing policy that addresses acute, primary, mental health, substance use disorders, and LTSS providers, as appropriate, and requires each MCO, PIHP and PAHP to follow those policies." Each plan must also "follow a documented process for credentialing and recredentialing of network providers" (438.214(b)(2)), and must demonstrate to the state that its network providers are credentialed as 438.214 requires (438.206(b)(6)).

Three related rules shape every Medicaid credentialing file:

• Plans "may not employ or contract with providers excluded from participation in Federal health care programs" (438.214(d)(1)).
• Plans "must comply with any additional requirements established by the State" (438.214(e)), which is how state contract terms become binding.
• The state itself "must screen and enroll, and periodically revalidate, all network providers" (438.602(b)(1)). A plan may contract pending state enrollment for up to 120 days, but must terminate if enrollment fails (438.602(b)(2)).

Where do you find your state's policy?

Usually in the state's model contract with its plans and in the plan's provider manual, which must reflect it. States do not all publish a standalone policy document. A practical shortcut is a carrier's own compliance summary. UnitedHealthcare publishes a "State and Federal Regulatory Addendum" to its credentialing plan (revised 9/2026) that lists, state by state, the credentialing requirements of each state Medicaid contract it holds. It is a carrier document, not law, but it shows what the states are asking plans to do. Several examples follow, as that addendum states them.

Which state contracts set deadlines?

• Texas. The MCO must use the Texas Association of Health Plans' contracted credentialing verification organization, complete credentialing so its claims system recognizes a new provider "no later than 90 calendar days after receipt of a completed application," and send written notice of all missing information "no later than 5 Business Days after receipt." Providers who qualify for expedited credentialing must be recognized within 30 calendar days. See Texas Medicaid credentialing deadlines.
• Pennsylvania. HealthChoices physical health MCOs must acknowledge an application within 10 calendar days, send a status letter within 30, and approve or deny within a maximum of 60 calendar days; a denial "should include all of the requirements that were not met." Credentialing cannot be completed until the provider has a Medicaid ID from the state, and the contract effective date runs back to the date a complete application was received. See Pennsylvania credentialing and network rules.
• Kentucky. The plan must complete credentialing within 30 days unless other law requires a different time, contract within 30 calendar days of credentialing, and treat claims as eligible for payment from the credentialing application date.
• Colorado. The plan must complete credentialing and contracting, or deny network admission, within 90 days for at least 90 percent of applications, measured from the provider's written request to contract.
• Florida. Providers must be "fully enrolled/onboarded within 60-days," measured from receipt of a complete application.
• New York. Files must show Medicaid fee-for-service enrollment status; a provider not on the state's active or pending enrollment file will be denied.

Centralized verification is a trend worth knowing. Texas already routes Medicaid credentialing verification through one organization, Pennsylvania's contract requires plans to use a state-procured centralized credentialing vendor when the department selects one, and Florida's contract lets the state procure a credentialing vendor for the whole program, all according to the same addendum.

How does the state policy help a stalled or denied file?

1. Get the reason. A plan that declines a provider owes written notice of the reason (42 CFR 438.12(a)(1)).
2. Compare it to the state policy. If the plan applied a criterion the state's policy does not include, or missed a contract deadline, that is a specific, checkable point.
3. Fix what is actually missing. State enrollment, an expired document, a CAQH mismatch. These are the fastest wins.
4. Ask the plan to reconsider, citing the state contract term.
5. Escalate to the state Medicaid agency if the plan does not answer, framed as a contract compliance issue. See the Medicaid provider discrimination rule for the complaint routes.

Is a uniform policy a right to a contract?

No. A uniform credentialing policy governs how plans check qualifications. It does not require a plan to contract with every qualified provider; 42 CFR 438.12(b)(1) still lets a plan decline providers beyond the number it needs. Kentucky's contract term, as UnitedHealthcare restates it, says this plainly: 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."

Our part, and yours

We research, prepare and organize; we are not a law firm. A Network Rejection Review ($249, credited toward a dispute) checks your file against your state's contract terms and the plan's manual. A Payer Network Dispute ($799 per payer) prepares the corrections, the reconsideration letter and, if needed, a state agency complaint draft, all for you to sign and send. We keep the deadlines. If credentialing is approved, the win fee is a flat $1,500. Legal questions go to a healthcare attorney.
