Medicare Advantage special needs plans (SNPs) have become a powerful growth engine for insurers. According to KFF, nearly half of all MA enrollment growth between 2024 and 2025 came from these targeted plans. By 2025, SNPs covered 21% of all MA enrollees. Clearly, the sector is expanding fast.
SNPs fall into three primary categories. Chronic condition SNPs (C-SNPs) serve members with specific long-term health issues. Dual-eligible SNPs (D-SNPs) cover individuals who qualify for both Medicare and Medicaid. Institutional SNPs (I-SNPs) support those who require nursing home-level care, either in a facility or at home. Every SNP must follow a CMS model of care framework, approved by the National Committee for Quality Assurance.
What Are Medicare Advantage Special Needs Plans?
Precision Care for Complex Members
SNPs deliver highly targeted care to members with the most complex health needs. Matt Eyles, Executive Vice President of Government and Business Strategy at Alignment Health, explained the appeal directly. “SNP growth is really happening because Medicare Advantage is becoming more clinically precise,” he said. “If you target specific conditions and build support around them, you can achieve better outcomes for seniors.”
The goal, moreover, is to keep members at home instead of in costly institutional settings. This approach benefits both the member and the insurer. Consequently, plans that invest in SNP infrastructure are seeing measurable clinical and financial returns.
Policy Landscape and Key Challenges
D-SNPs Face State-Level Complexity
D-SNPs have historically attracted more enrollees than C-SNPs. However, they now face mounting challenges. Many states are rolling out policies that push toward full integration between Medicare and Medicaid. As a result, insurers often must manage both programs simultaneously to maintain a D-SNP offering.
J. Patrick Foley, co-founder and CEO of Belong Health, noted that this state-by-state variability is steering carriers toward C-SNPs instead. “There’s been a real spike in chronic special needs plans,” Foley said. He also pointed to Medicaid eligibility redeterminations as a key disruption pushing that shift.
C-SNPs Offer Greater Predictability
C-SNPs present a distinct advantage: financial predictability. Because members already carry a qualifying diagnosis upon enrollment, plans can align payments with clinical acuity far sooner than in standard MA plans. This makes C-SNPs attractive for carriers seeking stable revenue alongside strong outcomes.
I-SNPs Remain a Specialized Niche
Not every payer pursues I-SNPs. Still, those that commit are seeing results. SCAN Health Plan, for instance, reported record I-SNP enrollment in 2026. This demonstrates that focused execution in a narrow segment can produce strong growth.
Growth Discipline and Market Strategy
Concentration Over Expansion
High enrollment numbers do not guarantee success with SNPs. Foley cautioned that geographic concentration matters more than scale. Plans that build dense networks of primary care providers within a focused region are better equipped to manage complex populations. “Using SNPs just to drive membership has the potential to cause disruptions,” he warned. “You need the right care model and the right physician relationships in place.”
UnitedHealthcare’s Integrated Approach
UnitedHealthcare leads the SNP market nationally. Betsy Chin, Senior Vice President of Medicare Advantage, identified the biggest cost drivers as medical complexity, social needs, and care coordination. “Sustainability is strongest where benefits, providers, and care management are aligned,” she said.
Furthermore, UnitedHealthcare evaluates SNP expansion market by market. The company takes local partnerships and community needs into account before entering new geographies. Chin confirmed the company is actively evaluating further growth opportunities across all three SNP types.
High-Touch Member Engagement
For Alignment Health, managing C-SNP members demands intensive outreach. The plan contacts C-SNP members an average of 24 times per year. This high-touch model reflects the clinical complexity these members carry. Without consistent engagement, outcomes and costs both suffer.
Competition and the Future of SNPs
New Entrants Are Arriving Fast
Competition in the SNP space is accelerating. Eyles has observed new entrants alongside heavy investment from national plans. Chin noted increased participation from regional insurers, Medicaid-focused organizations, and provider-aligned models. Together, these forces are reshaping the competitive landscape.
Balance Across Plan Portfolios
Leading insurers are not choosing between SNPs and general MA plans. Instead, they are building balanced portfolios that include both. “Medicare Advantage must continue to include a mix of plan types,” Chin said. “However, SNPs will play an increasingly important role as the population ages and needs become more complex.”
Foley agreed that balance is essential. Plans that rely too heavily on any single product type risk both regulatory and operational exposure.
Long-Term Outlook
Ultimately, success in the SNP space depends on care quality, not market share. “Success depends less on who enters the market and more on who can deliver integrated, high-quality care,” Chin said. Plans designed around specific member needs are better positioned to deliver value. As demographics shift and clinical complexity grows, SNPs will only become more central to the Medicare Advantage landscape.
