Updated Provider Revalidation Cycle
Summary
Illinois HFS has issued a provider notice implementing CMS guidance requiring accelerated Medicaid provider revalidation, compressing the standard five-year cycle to a two-year cycle for high-risk providers, providers without an NPI, laboratory providers, and Applied Behavior Analysis providers. Providers who revalidated or newly enrolled between April 30, 2025, and April 30, 2026, are exempt from the accelerated cycle. Failure to revalidate before the assigned cycle end date results in disenrollment, and reactivation cannot be made retroactive.
What this may mean
High-risk providers, non-NPI providers, labs, and ABA providers enrolled in Illinois Medicaid are subject to an accelerated two-year revalidation cycle under 42 CFR 455.414, with disenrollment and non-retroactive reactivation as the consequence of non-completion. Notification is delivered by email only (no USPS), and providers with multiple locations must revalidate each site individually. The change directly affects ABA providers, a category closely associated with the autism and behavioral health provider market.
