How states are shaping Medicaid managed care and marketplace participation

This week, our In Focus section reviews state policies designed to increase insurer participation in Medicaid managed care and Marketplace programs. As states seek to address healthcare costs, affordability, and consumer experiences, they are exploring a range of initiatives—from the rise of prescription drug affordability boards to cost containment commissions, cost growth benchmarks, transparency, and examination of mergers and acquisitions.  

A notable trend is the use of state policy and purchasing power to encourage or mandate that Medicaid managed care organizations (MCOs) offer Marketplace plans. Dual-market participation can help smooth coverage transitions, ensure continuity of care, and expand consumer choice. The remainder of this article addresses original research and analysis of this trend by Health Management Associates, Inc. (HMA), experts Zach ShermanAimee Lashbrook, and Hannah Turner

Current Landscape  

In 2024, enrollment in the Marketplace program has surged to more than 21 million, approximately a 30 percent increase from 2023. This growth was largely attributed to the temporary enhanced subsidies that allowed more people to access affordable coverage. Over the past several regulatory cycles, federal policymakers also have taken steps to further align the Marketplace framework with Medicaid on key issues, such as essential community provider access, eligibility and enrollment processes, and plan design standards. In response, states are innovating to meet federal requirements while pursuing their own healthcare goals related to coverage, affordability, access, and healthcare outcomes.  

Value Proposition  

A compelling value proposition for Medicaid MCOs to participate in the Marketplace (and vice versa) includes the ability to market to and retain people moving from one program to another as life circumstances change. Dual-market participation also supports diversification and growth strategies. In fact, enrollment in the Marketplace has nearly doubled since 2020. For Medicaid MCOs in particular, expanding product offerings to include Marketplace plans presents a unique opportunity to leverage existing provider networks and reimbursement arrangements to deliver more competitive rates. 

Consumers benefit when the same organization participates in both markets. Families with parents and children who obtain coverage under different programs have an opportunity to work with a single organization and choose providers from the same or overlapping networks. Income fluctuations may result in disenrollment from one program (e.g., Medicaid) and eligibility for a new program (e.g., Marketplace subsidies). Continuity of care policies can smooth these transitions in areas such as prior authorization, care management, and provider network.  

State Strategies to Increase Dual-Market Participation 

The Affordable Care Act expanded access to affordable health insurance coverage for as many as 45 million individuals by giving states the option to expand Medicaid and provide federal subsidies to people who purchase Marketplace plans. States are now using various strategies to encourage or require insurer participation in both programs to ease transitions for individuals and families “churning” from one program to another, increase competition and choice of Marketplace plans, and reduce the risk of coverage gaps. For example:  

  • Nevada is requiring any bidder that plans to respond to its upcoming Medicaid MCO procurement to separately submit a “good faith” response to the Battle Born State Plans (BBSP) RFP. This state-contracted, public option will be available on the Silver State Health Insurance Exchange beginning in 2026. Failure to submit a good faith proposal will disqualify an organization from participating in the Medicaid MCO procurement later this fall. Nevada’s current Medicaid MCOs must participate in the Marketplace by offering at least one Silver and one Gold qualified health plan (QHP) that has overlapping provider networks, serves the same service area, and charges reasonable premiums. 
  • Rhode Island and New Mexico require or intend to require that their Medicaid MCOs participate in the Marketplace. As an awardee of Rhode Island’s recent Medicaid MCO procurement, UnitedHealthcare, must reenter the HealthSource Rhode Island market in 2027. These states also have designed their Medicaid MCO auto-assignment methodology to favor enrollment in a Medicaid MCO affiliated with an individual’s previous Marketplace plan or a family member’s Marketplace plan.  
  • In its last Medicaid MCO procurement (2018), North Carolina offered bonus points to any bidder that agrees to offer a Marketplace MCO. The resulting contract codified the market entry commitment and included implications for failure to follow through. Nonfulfillment could result in the highest level of contract noncompliance and associated penalties. 
  • Arkansas expanded its Medicaid program using federal matching funds to purchase QHP coverage through the Marketplace. Minnesota, one of the few states offering a basic health program, contracts with the same organizations to provide coverage under both programs.  
  • Iowa uses contract language to encourage, but not require, Medicaid MCOs to participate in the Marketplace to facilitate continuity of care during coverage transitions. 

The Centers for Medicaid & Medicare Services (CMS) collaborated with states to promote continuity of coverage following the end of the Medicaid continuous enrollment requirement established in the Families First Coronavirus Response Act of 2020, also known as the Medicaid public health emergency (PHE) unwinding. This support includes the clarification of permissible outreach activities by Medicaid MCOs that also offer a Marketplace plan, information sharing, and other assistance. Many states have incorporated the CMS guidanceiii into Medicaid MCO contracts. North Carolina, Utah, and West Virginia include additional contract terms supporting their Medicaid MCOs’ ability to co-market Medicaid and Marketplace plans, including when an individual is losing Medicaid eligibility.  

What to Watch For 

Coverage transition challenges throughout the Medicaid PHE unwinding have highlighted the real-life impact of coverage gaps and the importance of policies and practices that promote uninterrupted access to healthcare coverage. Historic Marketplace enrollment levels and recent CMS guidance clarifying the allowability of outreach to people who are losing Medicaid coverage about Marketplace plan available make the prospect of dual-market participation increasingly attractive for Medicaid MCOs. A greater focus on improving continuity of care and Marketplace plan choice may lead to more states encouraging or requiring Medicaid MCOs to participate in the Marketplace.
