The structure
State agency enrollment is necessary but rarely sufficient. A state with five Medicaid MCOs is six enrollments. A group that enrolls with the state and stops will find most Medicaid patients out of network.
The major MCO operators
Centene (state-specific brands), Molina, the national carriers’ Medicaid arms (Aetna Better Health, Anthem/Wellpoint, UnitedHealthcare Community Plan), and regional nonprofits.Enrollment
1
Find the state agency's provider enrollment portal
Start at medicaid.gov state overviews.
2
Complete state enrollment
Including ownership and control disclosure — which should be consistent with your Medicare 855B disclosure.
3
Expect a screening level, and possibly a site visit
Federal rules require states to screen enrolling providers at limited, moderate, or high risk levels, with escalating requirements. Moderate and high can include unannounced site visits; high can include fingerprint-based background checks for owners.1
4
Contract and credential with every MCO in your service area
Check whether the state uses a single credentialing verification organization — it materially reduces the work.
Timely filing
State-specific — commonly anywhere from 90 days to 12 months, and MCO limits are contractual. Record each.Appeals
Plan appeal (for MCOs), then the state fair hearing process. Medicaid appeal rights are governed by state and federal Medicaid regulation and differ from commercial appeals.Revalidation
At least every five years, state-specific. Missing it means termination and claims stopping.The economics question
Whether to take Medicaid at all is a real business decision, and it is defensible either way. For: access mission, patient volume, network adequacy leverage with the state, and in some markets a large share of the population. Against: rates are generally the lowest of any payer, administrative burden is the highest, and the enrollment investment is substantial. Model contribution margin per Medicaid visit including administrative cost before committing. Make it a decision rather than a default.The 60-day rule applies
Medicaid overpayments are subject to the same 60-day report-and-return obligation as Medicare. See Report and return overpayments.Sources
