Shifting Dynamics of ACA Marketplace and Employer Health Plans

Hourly and part-time employees who obtained health insurance through the ACA Marketplace are facing fewer affordable options, prompting some to seek entry into employer health plans. These employees' eligibility for employer health plans largely depends on adherence to company-specific rules, many of which have not been updated for several years. This shift comes amid significant changes in the Affordable Care Act (ACA) Marketplace dynamics. The Centers for Medicare & Medicaid Services (CMS) recently revoked approximately 315,000 ACA Marketplace enrollments due to unauthorized enrollment, affecting over 760,000 individuals. Additionally, the expiration of enhanced premium tax credits in December 2025 has led to a 13% drop in enrollment, further straining the individual market. The Urban Institute anticipates that in 2026, an additional 3.2 million individuals will shift to employer-sponsored insurance due to the absence of these subsidies. According to the KFF 2025 Employer Health Benefits Survey, 80% of workers, on average, have access to company health plans. However, the availability of these plans drops significantly in firms with a high percentage of lower-wage employees, falling to 67% and even further to 53% in the retail sector. Part-time workers, heavily reliant on Marketplace plans, have just 27% coverage access in large enterprises—a stark contrast to their full-time counterparts. Under the ACA, large employers with 50 or more full-time equivalent employees must offer affordable insurance to those working 30 hours or more per week. While companies are not penalized for excluding lower-hour employees, those looking to expand eligibility must grapple with rising cost forecasts. Marsh's National Survey of Employer-Sponsored Health Plans anticipates an 8.2% rise in health benefit costs by 2027, the highest since 2003. 59% of employers plan cost-saving changes to health plans. Two-thirds of large firms might raise employee premium contributions. Reevaluation of plan designs, including waiting periods and tiered contributions, is crucial. Including part-time and hourly workers in employer health plans can both increase coverage and claims but excluding them risks employee attrition, especially if competitors offer better benefits. Employers can consider redesigning their health plans to manage costs while offering valuable options to their workforce. Employees maintaining individual coverage without employer support face increased financial burdens. Bronze plans, now 40% of selections, have seen a significant 37% hike in average deductibles, reaching $3,786. Providing supplemental insurance, such as accident and critical illness coverage, can help mitigate financial risks. However, these options are often underutilized due to limited understanding. The recent CMS decision to halt new agents and brokers from the federally facilitated Marketplace until February 2027 complicates matters further, making it challenging for employers to direct ineligible workers toward external services. With Marketplace changes and traditional subsidies waning, benefits teams must reconsider eligibility and contribution strategies for 2027. The absence of a subsidized individual market demands innovative approaches to retain a competitive benefits package, ensuring employees' needs are effectively met and minimizing potential financial risk exposure.
