- Application fee
- Michigan's 2012 bulletin MSA 12-55 charges the fee to every provider type except individual physicians and non-physician practitioners, for each enrolled provider type at initial enrollment and re-enrollment but not at revalidation or for updates. Medicare- or other-state-enrolled providers are exempt, and hardship exceptions can be requested in writing. 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
- MSA 12-55 classes newly enrolling home health agencies and DMEPOS suppliers as high risk, subject to fingerprint-based checks; every enrolled provider and 5%+ owner must consent to background checks including fingerprints. 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
- MSA 12-55 puts ambulance services, community mental health centers, CORFs, hospices, independent labs, physical therapists, and revalidating home health agencies and DMEPOS suppliers in the moderate tier, subject to unannounced pre- and post-enrollment site visits. 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
- MDHHS revalidates at least every five years (or sooner on request), with a 90-day window to finish in CHAMPS. Federal rule (42 CFR 455.414): every enrolled provider must be revalidated at least once every 5 years.
