What Is Medicaid?
Medicaid is a joint federal-state program established under Title XIX of the Social Security Act that provides health coverage to eligible low-income individuals, with each state administering its own program under federal minimum requirements.
- Practices serving Medicaid patients must enroll separately in each state's Medicaid program plus each Medicaid MCO they participate with.
- Provider enrollment can take 60-180 days; billing for services rendered before the effective date typically results in non-recoverable denials.

Medicaid is a joint federal-state program established under Title XIX of the Social Security Act that provides health coverage to eligible low-income individuals, with each state administering its own program under federal minimum requirements.
Definition
Medicaid covers more than 80 million Americans and is jointly funded by the federal government (through FMAP — Federal Medical Assistance Percentage, ranging from 50% to 76% depending on state) and the states. Each state operates its own program with its own provider enrollment process, fee schedule, prior-auth rules, and timely-filing window. The Affordable Care Act expanded Medicaid eligibility to adults under 138% FPL in expansion states. EPSDT benefits are mandatory for children under 21. Most states deliver Medicaid through Managed Care Organizations (MCOs) rather than fee-for-service.
Example
A pediatric office in Texas serving Medicaid patients submits claims to either Texas Medicaid (TMHP) for fee-for-service patients or to one of the state's MCOs (e.g., Superior, Molina, UnitedHealthcare Community Plan) depending on the patient's enrollment, each with its own portal, fee schedule, and timely filing window (95 days in Texas).
Common Misconceptions
Medicaid is not a single program — it is 56 different programs (50 states, DC, and 5 territories), each with distinct rules. Medicaid fee schedules are typically far below Medicare and commercial rates, and timely filing windows are often much shorter (30-180 days vs Medicare's 12 months).
Practical Application
Practices serving Medicaid patients must enroll separately in each state's Medicaid program plus each Medicaid MCO they participate with. Provider enrollment can take 60-180 days; billing for services rendered before the effective date typically results in non-recoverable denials.
