# Enroll in state Medicaid

> Why it's 50+ separate programs, the typical enrollment flow, screening levels and site visits, managed care plans requiring separate enrollment, and revalidation.

Medicaid enrollment means enrolling with the **state Medicaid agency** and then, separately, contracting with each **managed care organization** in that state. A state with five Medicaid MCOs is six enrollments, and none of them transfer from another state.

## Prerequisites

* The PC formed, with EIN and CP 575
* Type 2 NPI; Type 1 for each clinician
* The PC's bank account for EFT
* Medicare enrollment underway or complete, some states require or expedite based on it
* Practice location secured; a site visit is possible

## Why it's harder than Medicare

|              | Medicare                                    | Medicaid                                                     |
| ------------ | ------------------------------------------- | ------------------------------------------------------------ |
| Programs     | One federal program                         | 50+ state programs plus DC and territories                   |
| Application  | PECOS, standardized                         | State portal, each different                                 |
| Rules        | Federal, uniform                            | State-specific eligibility, covered services, provider types |
| Fee schedule | National framework with locality adjustment | State-set, generally lower                                   |
| Managed care | Optional (MA)                               | **Dominant**, most beneficiaries are in MCOs                 |
| Revalidation | Every 5 years                               | At least every 5 years, state-specific                       |

## The two layers

**Enrolling with the state agency is necessary but usually not sufficient.** Most Medicaid beneficiaries are enrolled in managed care plans, and each MCO requires its own contract and credentialing on top of state enrollment. A group that completes state enrollment and stops will find most Medicaid patients out of network.

## Steps

<Steps>
  <Step title="Identify the state's program structure">
    * The state Medicaid agency's provider enrollment portal
    * Which MCOs operate in your service area, commonly Centene brands, Molina, national carriers' Medicaid arms, and regional nonprofits
    * Whether the state uses a single credentialing verification organization for MCOs
  </Step>

  <Step title="Complete state agency enrollment">
    Typically requires: entity information, NPIs, licenses, ownership and control disclosure, a provider agreement, and EFT details.

    Ownership disclosure requirements are extensive and mirror the federal ones. See the caution in [Enroll in Medicare](/guides/enrollment/enroll-in-medicare) — the same MSO-managing-control question applies, and the answer should be consistent across both.
  </Step>

  <Step title="Expect a screening level and possibly a site visit">
    Federal rules require states to screen enrolling providers at **limited**, **moderate**, or **high** risk levels, with escalating requirements. Moderate and high risk categories can include unannounced site visits, and high risk can include fingerprint-based criminal background checks for owners.<sup>1</sup>

    Which category applies depends on provider type and history. Know yours before you're surprised by an inspector.
  </Step>

  <Step title="Contract and credential with each MCO">
    Separately, per plan. Each has its own application, its own credentialing committee, and its own effective date. Many pull from CAQH — make sure each is authorized in the profile.
  </Step>

  <Step title="Set up EDI, ERA, and EFT per payer">
    Once for the state agency, once per MCO. See [Set up EDI, ERA, and EFT](/guides/enrollment/set-up-edi-era-eft).
  </Step>

  <Step title="Record every effective date and revalidation date">
    In the enrollment grid, per entity, per plan, per clinician.
  </Step>
</Steps>

## Timeline

**60–180 days for state enrollment**, and 90–180 days per MCO, often running in parallel. Start early — this is frequently the longest pole in a new state.

## Multi-state groups

Everything about Medicaid is per-state. A five-state group has five state enrollments plus every MCO in each. This is the single largest driver of enrollment workload in a multi-state expansion.

Two things that help:

* **CAQH profiles transfer.** Add the new state's license and location, re-attest, authorize the new plans.
* **Your process transfers.** The documents packet, the tracking grid, and the follow-up cadence are reusable even when nothing else is.

See [Enroll with payers, again](/start/second-state/payer-enrollment-again).

## The economics question

Worth asking before investing months: **should you take Medicaid at all?**

**For it:** access mission, patient volume, network adequacy leverage with the state, and in some markets a large share of the population.

**Against it:** rates are generally the lowest of any payer, administrative burden is the highest, and the enrollment investment is substantial.

Model the contribution margin per Medicaid visit including administrative cost before committing. This is a real business decision, and it is defensible either way, but it should be a decision rather than a default.

## Verify it worked

* [ ] State agency enrollment approved; effective date recorded
* [ ] Screening level known; any site visit completed
* [ ] Every MCO in your service area identified
* [ ] Contract and credentialing complete with each MCO
* [ ] CAQH authorized for each plan
* [ ] EDI, ERA, and EFT set up per payer, with EFT to the **PC's** account
* [ ] Revalidation dates calendared
* [ ] Correspondence address monitored

## Common failure modes

| Failure                                                    | Consequence                               |
| ---------------------------------------------------------- | ----------------------------------------- |
| Enrolling with the state and stopping                      | Out of network for most Medicaid patients |
| Missing an MCO                                             | A whole population segment out of network |
| Unprepared for a site visit                                | Application delayed or denied             |
| Ownership disclosure inconsistent with the Medicare filing | Raises questions in both                  |
| Assuming enrollment transfers between states               | It doesn't, at all                        |
| Missed revalidation                                        | Termination; claims stop                  |
