Medicaid credentialing is really two processes. First, the provider enrolls with the state Medicaid agency. Then the provider is credentialed separately with each Medicaid managed care organization (MCO) the practice wants to see patients from. Commercial credentialing is one payer, one process. Medicaid has a federal screening layer, a state enrollment layer, and a plan layer, and missing any one of them means claims don’t get paid.
How Is Medicaid Credentialing Different From Commercial Credentialing?
- State enrollment comes first. Each state runs its own Medicaid enrollment system and forms. Being enrolled in one state doesn’t carry over to another.
- Federal screening rules apply. Federal regulations at 42 CFR Part 455 set the screening that states must perform.
- MCOs credential on top of that. In states where most Medicaid patients are in managed care, state enrollment alone doesn’t get you paid by the plans.
- Ordering and referring providers must enroll too. Federal rules require physicians who order or refer services for Medicaid patients to be enrolled, even if they never bill Medicaid themselves.
What Federal Screening Rules Apply?
Under 42 CFR Part 455, as reflected in state Medicaid plans, states must:
- Screen by risk level. Providers are placed in limited, moderate, or high risk categories, and screening depends on the category.
- Do site visits before and after enrollment for moderate and high risk providers.
- Run criminal background checks, including fingerprints, where the risk level or state law requires them.
- Revalidate every provider at least every 5 years.
- Collect an application fee from institutional providers. For calendar year 2026 the federal fee is $750, up from $730.
Why Medicaid Credentialing Takes Longer
- Two sets of applications. State enrollment has to clear before most MCOs will finish credentialing.
- State systems vary. Some states are fully online, others still need notarized paper forms.
- Group and individual enrollment are separate. The group (Type 2 NPI) and each rendering provider (Type 1 NPI) usually enroll separately and must be linked.
- Missed revalidation deadlines end enrollment, and claims stop paying until it’s restored.
A Medicaid Credentialing Checklist
- Confirm active Type 1 and Type 2 NPIs and matching taxonomy codes.
- Enroll the group and each rendering provider with the state Medicaid agency.
- Make sure the CAQH profile is complete and attested, since many MCOs pull from it.
- List the MCOs in your state and apply to each one you want to see patients from.
- Track each revalidation date and start well before it.
- Enroll ordering and referring providers even if they don’t bill.

Frequently Asked Questions About Medicaid Credentialing
Is Medicaid credentialing the same as Medicaid enrollment?
Not exactly. Enrollment is registering with the state Medicaid agency. Credentialing with Medicaid managed care plans is a separate process each plan runs, and most practices need both.
How often does Medicaid revalidation happen?
Federal rules require states to revalidate every enrolled provider at least every 5 years. Some states set shorter cycles.
Is there a fee to enroll in Medicaid?
Institutional providers pay a federal application fee, which is $750 for calendar year 2026. Individual practitioner rules vary by state.
Do ordering physicians need Medicaid enrollment?
Yes. Federal rules require physicians who order or refer services for Medicaid patients to be enrolled in the state’s Medicaid program.
