# Missouri Medicaid Enrollment: MO HealthNet Rules and Fees > Missouri Medicaid enrollment: MO HealthNet revalidates at least every five years, charges institutional providers $750, and fingerprints high risk owners. Source: https://webillhealth.com/missouri-medicaid-provider-enrollment/ Publisher: WeBill Health Last updated: November 12, 2026 Missouri Medicaid ## MO HealthNet enrollment, active and paid A MO HealthNet provider number kept active, a revalidation filed before its due date, and payments that never pause. [Request a Revenue Defense Audit](https://webillhealth.com/revenue-defense-audit/request/) Missouri Medicaid, MO HealthNet, is enrolled through Missouri Medicaid Audit and Compliance (MMAC), which processes new, reenrolling and revalidating providers under state regulations 13 CSR 65 2 and 13 CSR 70 3.020. Its [new provider](https://mmac.mo.gov/providers/provider-enrollment/new-providers/) and [revalidation](https://mmac.mo.gov/providers/provider-enrollment/revalidating-providers/) pages, with the [fee](https://mmac.mo.gov/providers/provider-enrollment/new-providers/application-fee/) and [fingerprint](https://mmac.mo.gov/providers/provider-enrollment/new-providers/fingerprint-based-criminal-history-checks/) rules, are the sources below. * Revalidation cycle Every active MO HealthNet provider revalidates at least every five years; revalidation means no break in active status, reenrollment means there was one. [MMAC, New Providers](https://mmac.mo.gov/providers/provider-enrollment/new-providers/) * Due dates Since January 7, 2019 providers check their revalidation due date online and file with supporting documents to avoid an interruption in payments. [MMAC, Revalidating Providers](https://mmac.mo.gov/providers/provider-enrollment/revalidating-providers/) * Application fee $750 for new and revalidating institutional providers, collected since July 1, 2015; physicians, dentists and individual practitioners pay none. [MMAC, Application Fee](https://mmac.mo.gov/providers/provider-enrollment/new-providers/application-fee/) * Fee exemptions A fee paid to Medicare or another state Medicaid within two years exempts the provider; a CMS hardship waiver is refunded after the fee is paid. [MMAC, Application Fee](https://mmac.mo.gov/providers/provider-enrollment/new-providers/application-fee/) * Fingerprints High risk providers submit two sets of fingerprints for every owner at five percent or more, checked by the FBI and the Missouri State Highway Patrol. [MMAC, Fingerprint Based Criminal History Checks](https://mmac.mo.gov/providers/provider-enrollment/new-providers/fingerprint-based-criminal-history-checks/) * Fingerprint exemption Owners fingerprinted for Medicare or another state Medicaid in the last two years do not repeat it for Missouri. [MMAC, Fingerprint Based Criminal History Checks](https://mmac.mo.gov/providers/provider-enrollment/new-providers/fingerprint-based-criminal-history-checks/) * What we see in practice 45 to 90 days from submission to an active Medicaid ID. ## In the official words > Revalidation means there is no break in active status. [Missouri Medicaid Audit and Compliance (MMAC)](https://mmac.mo.gov/providers/provider-enrollment/new-providers/) > Missouri began collecting application fees July 1, 2015. [Missouri Medicaid Audit and Compliance (MMAC)](https://mmac.mo.gov/providers/provider-enrollment/new-providers/application-fee/) ## Missouri separates revalidation from reenrollment MMAC processes applications from new, reenrolling and revalidating providers under 13 CSR 65 2 and 13 CSR 70 3.020. [MMAC, New Providers](https://mmac.mo.gov/providers/provider-enrollment/new-providers/) The distinction matters for payment. A reenrolling provider was active once but is inactive when the application arrives; revalidation means there has been no break in active status. [MMAC, New Providers](https://mmac.mo.gov/providers/provider-enrollment/new-providers/) [MMAC, New Providers](https://mmac.mo.gov/providers/provider-enrollment/new-providers/) Every active MO HealthNet provider must revalidate at least every five years to stay a MO HealthNet provider, which is also the federal floor. [MMAC, New Providers](https://mmac.mo.gov/providers/provider-enrollment/new-providers/) [MMAC, Revalidating Providers](https://mmac.mo.gov/providers/provider-enrollment/revalidating-providers/) [42 CFR 455.414](https://www.ecfr.gov/api/versioner/v1/full/2026-10-29/title-42.xml?part=455§ion=455.414) Since January 7, 2019, providers and their authorized representatives have been able to look up their revalidation due dates online, and MMAC asks them to file the revalidation application with any supporting documentation before that date to avoid any interruption in payments. [MMAC, Revalidating Providers](https://mmac.mo.gov/providers/provider-enrollment/revalidating-providers/) [MMAC, Revalidating Providers](https://mmac.mo.gov/providers/provider-enrollment/revalidating-providers/) [MMAC, Revalidating Providers](https://mmac.mo.gov/providers/provider-enrollment/revalidating-providers/) A separate Revalidations Unit handles those files. [MMAC, Revalidating Providers](https://mmac.mo.gov/providers/provider-enrollment/revalidating-providers/) ## How enrollment works, step by step 1. Check whether the provider type can enroll electronically. MMAC says select provider types can, and those that cannot request an application package by email. [MMAC, New Providers](https://mmac.mo.gov/providers/provider-enrollment/new-providers/) [MMAC, New Providers](https://mmac.mo.gov/providers/provider-enrollment/new-providers/) 2. Pay the fee if the provider is institutional. The fee is $750 for new and revalidating institutional providers; physicians, dentists and other individual practitioners are exempt. [MMAC, Application Fee](https://mmac.mo.gov/providers/provider-enrollment/new-providers/application-fee/) [MMAC, Application Fee](https://mmac.mo.gov/providers/provider-enrollment/new-providers/application-fee/) It is paid through the state’s vendor by card or electronic check, with a convenience fee, or by cashier’s check or money order; cash and personal or business checks are refused. [MMAC, Application Fee](https://mmac.mo.gov/providers/provider-enrollment/new-providers/application-fee/) [MMAC, Application Fee](https://mmac.mo.gov/providers/provider-enrollment/new-providers/application-fee/) [MMAC, Application Fee](https://mmac.mo.gov/providers/provider-enrollment/new-providers/application-fee/) 3. Attach proof of payment. An institutional application is not processed until proof the fee was paid is included. [MMAC, Application Fee](https://mmac.mo.gov/providers/provider-enrollment/new-providers/application-fee/) A fee paid to Medicare or another state Medicaid within the last two years counts instead. [MMAC, Application Fee](https://mmac.mo.gov/providers/provider-enrollment/new-providers/application-fee/) 4. Fingerprint the owners if the provider type is high risk. Two sets of fingerprints go in for every person with five percent or more direct or indirect ownership, through the state’s electronic vendor, and are checked by the FBI and the Missouri State Highway Patrol. [MMAC, Fingerprint Based Criminal History Checks](https://mmac.mo.gov/providers/provider-enrollment/new-providers/fingerprint-based-criminal-history-checks/) [MMAC, Fingerprint Based Criminal History Checks](https://mmac.mo.gov/providers/provider-enrollment/new-providers/fingerprint-based-criminal-history-checks/) [MMAC, Fingerprint Based Criminal History Checks](https://mmac.mo.gov/providers/provider-enrollment/new-providers/fingerprint-based-criminal-history-checks/) [MMAC, Fingerprint Based Criminal History Checks](https://mmac.mo.gov/providers/provider-enrollment/new-providers/fingerprint-based-criminal-history-checks/) MMAC staff then review the records to confirm the owners and managers are eligible. [MMAC, Fingerprint Based Criminal History Checks](https://mmac.mo.gov/providers/provider-enrollment/new-providers/fingerprint-based-criminal-history-checks/) 5. Ask for a hardship waiver only after paying. A CMS hardship waiver can be requested, but the fee must be submitted before MMAC processes the application, and is refunded if CMS approves. [MMAC, Application Fee](https://mmac.mo.gov/providers/provider-enrollment/new-providers/application-fee/) [MMAC, Application Fee](https://mmac.mo.gov/providers/provider-enrollment/new-providers/application-fee/) Missouri has collected the fee since July 1, 2015, [MMAC, Application Fee](https://mmac.mo.gov/providers/provider-enrollment/new-providers/application-fee/) and the fingerprint procedure applies to new and revalidating providers alike. [MMAC, Fingerprint Based Criminal History Checks](https://mmac.mo.gov/providers/provider-enrollment/new-providers/fingerprint-based-criminal-history-checks/) With those steps in front of a decision, our planning figure for a new Missouri provider is 45 to 90 days from submission to an active Medicaid ID. ## What the two year rules are worth Two exemptions reward recent Medicare or other state work. A provider that paid the application fee to Medicare or another state Medicaid within two years of the Missouri submission date is exempt from paying it again. [MMAC, Application Fee](https://mmac.mo.gov/providers/provider-enrollment/new-providers/application-fee/) And an owner who submitted fingerprints to Medicare or another state Medicaid in the last two years does not submit them for the Missouri application. [MMAC, Fingerprint Based Criminal History Checks](https://mmac.mo.gov/providers/provider-enrollment/new-providers/fingerprint-based-criminal-history-checks/) Both depend on dates and proof, which is why a multistate group keeps its Medicare enrollment receipts and fingerprint confirmations with the file. ## Where Missouri enrollments lose money The expensive lapse is a revalidation that slips past its due date, because the provider then comes back as a reenrollment, with a break in active status rather than a continuous one. [MMAC, New Providers](https://mmac.mo.gov/providers/provider-enrollment/new-providers/) [MMAC, New Providers](https://mmac.mo.gov/providers/provider-enrollment/new-providers/) MMAC’s own wording is that the revalidation and its documents are filed to avoid any interruption in payments. [MMAC, Revalidating Providers](https://mmac.mo.gov/providers/provider-enrollment/revalidating-providers/) The slow lapse is an unprocessed application. An institutional file without proof of the fee waits, and a hardship waiver does not change that order: fee first, refund later. [MMAC, Application Fee](https://mmac.mo.gov/providers/provider-enrollment/new-providers/application-fee/) [MMAC, Application Fee](https://mmac.mo.gov/providers/provider-enrollment/new-providers/application-fee/) A high risk provider whose owners have not been fingerprinted waits on the FBI and Highway Patrol results before eligibility is confirmed.
