- Application 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
- 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
- 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
- Idaho is moving its high-risk provider types to revalidation every three years, more often than the federal five-year minimum, and posts its 2026 revalidation correspondence with CMS on its enrollment page. Federal rule (42 CFR 455.414): every enrolled provider must be revalidated at least once every 5 years.

Managed care covers behavioral health (Idaho Behavioral Health Plan, Magellan), dental (Idaho Smiles, MCNA) and dual eligibles (MMCP and Idaho Medicaid Plus through Molina Healthcare of Idaho and UnitedHealthcare Community Plan of Idaho).
