What is Medicaid Managed Care and the Role of MCOs in Healthcare?

By  Senior Market Advisors  on January 1, 2025

Understanding managed care and Medicaid managed care organizations (MCOs) is essential for insurance agents. MCOs play a key role in providing high-quality health care services for millions of Medicaid beneficiaries, many of which are also dual eligible for Medicare.

Below we will help simplify what MCOs are, how they work, and why they’re critical for you to understand.

If you’ve ever struggled to explain managed care plans to clients (you’re not alone), this article will provide an easy-to-follow breakdown plus an FAQ section to address some common questions.

What is Managed Care?

Managed care is a type of health care delivery system designed to control costs, improve the quality of care, and connect enrollees with the right health care providers. Instead of paying for every service separately (known as fee-for-service), managed care plans receive a fixed monthly payment, known as capitation, to provide Medicaid services to beneficiaries.

Think of an MCO (Managed Care Organization) like a team manager who organizes and pays for care, ensuring enrollees have access to doctors, hospitals, behavioral health services, and even long-term care when needed.

What is Medicaid Managed Care?

Medicaid managed care is a system where state Medicaid agencies contract with MCOs to deliver health care benefits to Medicaid beneficiaries. Instead of the government paying directly for care, the state Medicaid agency pays MCOs to provide services, such as:

  • Primary care and specialist care
  • Hospital stays
  • Behavioral health services
  • Long-term services and nursing facility care

According to Kaiser, currently, over 74% of Medicaid beneficiaries receive care through Medicaid MCOs across the country.

How Do MCOs Work?

Here’s a simple breakdown:

  1. Capitation Payments: The government gives the MCO a set amount of money (capitation) each month to care for each enrollee.
  2. Care Coordination: MCOs connect enrollees with doctors, specialists, and other health care providers.
  3. Rules and Networks: MCOs work with providers within their network and set rules, like requiring prior authorization for specific treatments.
  4. Focus on Quality: Many MCOs use quality improvement programs to ensure high-quality care while managing costs.

Why is Managed Care Important for Agents?

As an agent, understanding Medicaid managed care helps you guide clients effectively. Here’s why it matters:

  • Most Medicaid Beneficiaries Use MCOs: In most states, the majority of beneficiaries are enrolled in MCOs for their Medicaid services.
  • Improved Care Coordination: MCOs help clients access primary care, specialists, and even social support through community-based services.
  • State-Specific Rules: Each state’s Medicaid program is different, and agents need to understand their state’s rules for enrollment and eligibility.

Key Questions Answered: FAQs

What does MCO stand for with Medicaid?

MCO stands for Managed Care Organization. It is a company that provides health care services to Medicaid enrollees under a contract with the state.

What is the difference between MCO and Medicaid?

Medicaid is a government-funded health insurance program. An MCO is a private or non-profit organization that manages and provides Medicaid benefits to Medicaid beneficiaries.

What is an example of an MCO?

Some of the largest Medicaid MCOs include UnitedHealthcare, Aetna, Elevance Health (formerly Anthem), Molina Healthcare, Humana, and Centene.

What role does Care Coordination play?

Care coordination ensures that patients receive the right care at the right time. For example, if a beneficiary needs mental health support or long-term care, the MCO helps connect them with the appropriate provider.

How do I choose the best Medicaid MCO for my healthcare needs?

Clients should consider:

  • The MCO’s network of doctors, specialists, and hospitals.
  • Coverage for additional services like behavioral health services or long-term services.
  • State-specific benefit plans and flexibilities.

How does Medicaid MCO enrollment affect access to specialists?

MCOs typically require enrollees to see a primary care provider first for referrals to specialists. This helps manage costs and ensures coordinated care.

How do I enroll in a Medicaid MCO?

Beneficiaries can enroll through their state Medicaid agency during open enrollment periods or special enrollment windows based on eligibility.

Are newborns in State Custody automatically enrolled?

Yes, in certain states like New Mexico, newborns in state custody may be automatically enrolled in a specific health plan, like the Presbyterian Health Plan.

What is the start date for newly selected MCOs?

Start dates for new MCO contracts vary by state and are typically announced by the state Medicaid agency during their procurement process.

When will MCOs deliver member lists to providers?

Providers typically receive member lists shortly after enrollment or during the start of a new managed care program year.
