Impact of ACA on Healthcare Premiums and Enrollment Trends

In January, the "Great Healthcare Plan" was introduced with the goal of addressing healthcare expenditures, spotlighting the costs tied to the Affordable Care Act (ACA). The expiration of enhanced tax subsidies, which previously aided in reducing ACA insurance costs, has shifted focus to the issue of premium affordability.

With these subsidies gone, many Californians now face increased premiums, with average monthly contributions for ACA premiums doubling. This financial strain has led to a decrease in ACA enrollments by over a million. Ongoing debates persist regarding whether specific ACA provisions, such as essential health benefits (EHBs), contribute to these cost increases. EHBs require mandatory coverage for services like emergency care and prescription drugs without any annual limits.

Data from the Paragon Health Institute shows that since 2014, average premiums for a 50-year-old under ACA policies have soared by 129%, contrasting with a 68% increase in employer-based plan premiums over the same timeframe. According to Paragon Health Institute's Brian Blase, this highlights the ACA's significant impact on healthcare costs in the individual market. Initially, individual policies, required to cover a broader range of services post-ACA, witnessed a rise in premiums as they became more comprehensive, aligning with the coverage scope of employer plans.

States like Massachusetts and New York experienced milder premium hikes post-ACA, attributed to their pre-existing EHB-like coverage mandates. These states had higher premiums before ACA due to additional provisions. Blase asserts that underlying inflationary drivers within ACA policies, alongside the expiration of pandemic-era subsidies, contribute more to premium growth compared to similar factors within employer plans.

Even before the ACA's introduction, premiums in the individual market were already increasing, as research indicates steady upticks from 2008 to 2010. Currently, ACA deductibles are also on the rise, with bronze plan deductibles averaging $7,476, up from $5,113 in 2014 according to KFF. The Trump administration's preference for high-deductible plans aims to enhance affordability and expand coverage options through possible regulatory changes set for 2027.

Despite these adjustments, catastrophic plans maintain a niche presence, with limited enrollment and restricted federal subsidy access. ACA plans are required to cover essential health benefits across ten categories, such as preventive services at no additional charge, though other services often involve out-of-pocket expenses. The inclusion of EHBs is argued to facilitate preventive care savings through early disease detection, potentially lowering costs. However, broad coverage standards and limits on premium variability based on age or health status are frequently cited as drivers of rising costs.

States possess the ability to customize EHBs, potentially including additional services like bariatric surgery or hearing aids, but this flexibility might impact premium levels. While EHB mandates ensure comprehensive patient coverage, they also pose challenges in managing premium costs and provider billing practices, fueling ongoing debate about their role in premium hikes.
