The Affordable Care Act (ACA) has brought many improvements to the healthcare system. For example, it has made prescription drugs more affordable. It also has ensured that people who are disabled and elderly will have access to medical coverage. However, the ACA has also faced several challenges. Its implementation has been complicated and the law has been contested in court. In addition, changes in presidential administrations and shifts in the composition of Congress have impacted its implementation and stability.

The ACA was designed to expand health insurance coverage in three ways: expanding Medicaid eligibility; creating new exchange markets where individuals can purchase coverage and receive financial help to afford premiums and cost-sharing; and requiring employers who do not offer coverage to pay penalties, with exceptions for small employers. The ACA has helped reduce the number of uninsured Americans, and it has improved the quality of the health insurance available for those who are insured.

In order to provide adequate healthcare, it is necessary for all Americans to have access to affordable insurance. However, some individuals find it difficult to obtain and maintain affordable health coverage, particularly those with preexisting conditions or who have had recent job loss. To address this problem, the ACA introduced a series of countervailing measures including premium subsidies, coverage expansions, and an individual mandate to enroll in health insurance.

Since the ACA was passed, more than 13 million low-income Americans have gained health insurance coverage through the expansion of the Medicaid program. In addition, more than 10 million people have purchased private health insurance through the ACA’s marketplaces and received financial assistance to reduce their monthly premium costs. This coverage is vital to the health of all Americans, particularly those with lower incomes, as these individuals often face higher costs for the most essential healthcare services.

The ACA requires all health plans to cover certain preventive benefits, such as screenings for cancer and other diseases and recommended immunizations. It also prohibits the denial or revocation of coverage for those with preexisting conditions and limits how much health insurers can charge for premiums based on age, location, tobacco use, and other factors. It also requires that health plans disclose their medical loss ratios to consumers.

In an effort to keep premiums affordable, the ACA includes a series of temporary programs that help reduce the financial burden on health insurers by covering a portion of their claims for the first few years after the marketplaces opened. These programs have helped mitigate the steep price increases that have occurred in recent years. However, these programs are set to expire at the end of 2025, resulting in significant increases in monthly health insurance premiums for many people who are purchasing subsidized coverage through the marketplaces.
