Fiscal agent

Gainwell Technologies (DOM fiscal agent; sends recredentialing notices and does revalidation site visits)

Application fee

DOM charges institutional provider taxonomies on its list (e.g., home health, hospice, ASCs, ESRD, FQHCs, mental health centers, rehab facilities) $750 for 2026. The fee applies at initial enrollment, reactivation, revalidation or re-enrollment, ownership changes and new practice locations, and is paid by check to the Division of Medicaid (marked with the application tracking number) and mailed to Gainwell. Providers that already paid Medicare or another state are exempt. 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

Revalidating providers may have to submit fingerprints as part of screening. 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

Revalidating providers may need a site visit, done by Medicaid's fiscal agent. 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

DOM restarted revalidation on October 1, 2023, mailing notices to providers enrolled five years or more; revalidation is done in the MESA Provider Portal. DOM published a Medicaid Provider Revalidation Roadmap in August 2026. Federal rule (42 CFR 455.414): every enrolled provider must be revalidated at least once every 5 years.

HCBS 80/20 rule

Federal baseline: 42 CFR 441.302(k) requires the state to show that each provider spends at least 80% of Medicaid payments for homemaker, home health aide and personal care services under 1915(c) waivers on direct care worker pay and benefits. Compliance starts 2030-07-09 (for managed care, the first rating period starting on or after that date); annual payment-adequacy reporting under 441.311(e) starts 2028-07-09. A state may set a lower share for state-defined small providers and exempt providers facing hardship, each only through a public notice-and-comment process. The eCFR text has not changed since 2024-07-09. No state-published 80/20 implementation step (small-provider criteria, hardship exemption or reporting guidance) was found for this state in the official sources reviewed.
