To bill Missouri Medicaid, enroll through MMAC online provider enrollment application / eMOMED, run by None named on the enrollment pages — Missouri Medicaid Audit & Compliance. The process has 6 steps, listed below with the documents the state asks for.
- Program
- MO HealthNet (Missouri Medicaid, Department of Social Services)
- Enrollment portal
- MMAC online provider enrollment application / eMOMED
- Fiscal agent
- None named on the enrollment pages — Missouri Medicaid Audit & Compliance (MMAC) runs provider enrollment; eMOMED is the provider web portal
- Application fee
- MMAC charges new and revalidating institutional providers $750 (Missouri began collecting July 1, 2015). Proof of payment through the state's payment vendor must come with the application; providers that paid Medicare or another state within the past two years are exempt, and if CMS grants a hardship waiver MMAC refunds the fee. Federal rule (42 CFR 455.460): the state must collect the CMS application fee from institutional providers that are newly enrolling or re-enrolling; individual physicians and non-physician practitioners are exempt, as are providers already enrolled in (or that already paid the fee to) Medicare or another state's Medicaid/CHIP. CMS set the fee at $750 for calendar year 2026.
- Fingerprinting
- Missouri requires two sets of fingerprints from every 5%+ owner of a high-risk provider, taken through MACHS/IDEMIA and checked by the FBI and Missouri State Highway Patrol; owners fingerprinted by Medicare or another state in the past two years are exempt. Federal rule (42 CFR 455.434, 455.450(c)): providers the state places in the 'high' categorical risk level, and anyone owning 5% or more of such a provider, must submit fingerprints for a criminal background check.
- Site visit
- MMAC has done pre- and post-enrollment site visits for new, re-enrolling and revalidating moderate- and high-risk providers since July 1, 2015, skipping them if Medicare or another state did one in the past two years. Federal rule (42 CFR 455.432, 455.450(b)-(c)): the state must do site visits before and after enrollment for providers in the 'moderate' or 'high' risk levels, and any enrolled provider must allow unannounced on-site inspections.
- Revalidation
- MMAC revalidates every active provider at least every five years through eMOMED and rejects revalidations that lack required documents. Enrollment is deactivated if missing documents are not sent within 30 days of notice. Federal rule (42 CFR 455.414): every enrolled provider must be revalidated at least once every 5 years.
