Contract and credential with every MCO in your service area
Timely filing
State-specific: commonly anywhere from 90 days to 12 months, and MCO limits are contractual. Record each.Payment cycles
Medicaid fee-for-service does not pay claims as it adjudicates them. Each program accumulates adjudicated claims and releases payment on a fixed cycle, usually called a checkwrite or financial cycle, so the day money moves is set by that calendar rather than by the day the claim finished. The 835 is generated when the cycle runs and the EFT settles one to several banking days later, which is why the remittance can be visible days before the deposit. Of the 51 jurisdictions, 43 run a weekly cycle. Alabama, Connecticut, Minnesota, Missouri, and Rhode Island pay every other week. Tennessee has no general fee-for-service cycle because virtually every claim is paid by an MCO. New Mexico and Iowa do not publish a cadence. Three patterns recur and matter more than the weekday:- Managed care pays on its own calendar. In most states the fee-for-service cycle below covers a minority of Medicaid dollars. Each MCO’s payment schedule is contractual and separate.
- Fiscal-year-end holds. States with a June 30 year end (California, Maine, Missouri, North Carolina, Virginia, Wyoming) and Texas (August 31) skip or compress a cycle at the boundary and release it in the new year. Model a two-week gap there.
- Cash-availability holds. West Virginia, Maine, and Alabama release payment subject to available funds, so an approved claim can wait past its scheduled cycle. Illinois decouples the remittance from the Comptroller’s warrant entirely.

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
