Understanding the Affordable Care Act (ACA)Passed in March 2010, the Affordable Care Act (ACA)—frequently referred to as “Obamacare”—was a landmark piece of legislation under President Barack Obama. It aimed to broaden access to affordable health insurance, particularly through the creation of the Health Insurance Marketplace (healthcare.gov). A few core provisions include the expansion of Medicaid and new protections for people with pre-existing medical conditions, who can no longer be denied coverage or charged higher rates.

Obamacare introduced subsidies and cost-sharing reductions for lower-income individuals, extended parental insurance coverage for dependents up to age 26, and mandated that all Marketplace plans cover essential health benefits such as maternity care, prescription drugs, mental health services, and preventive care.


While some parts of the ACA influenced Medicare—such as enhancements to Medicare Advantage and cost-saving reforms—its main focus was improving healthcare access for the uninsured and those under 65. Critics argue the ACA raised premiums for certain groups, especially those ineligible for subsidies. Still, the ACA transformed healthcare access for millions and remains central to health policy debates today.


A Closer Look at Medicare


Established in 1965, Medicare is a federal health insurance program primarily designed for people aged 65 and older, along with younger individuals with qualifying disabilities or end-stage renal disease. Medicare includes several parts:

  • Part A covers hospital stays, skilled nursing care, hospice, and some home health services. Most people do not pay a premium if they’ve worked and paid Medicare taxes.

  • Part B includes outpatient services, preventive care, and necessary medical supplies. Enrollees typically pay a monthly premium.

  • Part C (Medicare Advantage) is offered through private insurers and combines Parts A and B, often with added benefits like dental or vision care.

  • Part D helps cover prescription drugs and is available via standalone plans or Medicare Advantage packages.


Medicare provides broad coverage but may leave certain gaps—like dental and vision—that many address through Medigap or Medicare Advantage.

How Obamacare and Medicare Differ

Though the ACA impacted aspects of Medicare, the programs serve distinct populations and have separate goals:

  • Target Population: Obamacare primarily helps individuals under 65, including low-income families and those without employer coverage. Medicare is for people 65+ and those with certain disabilities.

  • Coverage Expansion: Obamacare introduced marketplaces and expanded Medicaid eligibility (in states that adopted it), offering insurance options to millions. Medicare’s eligibility criteria are not income-based (except for certain assistance programs).

  • Medicare Reforms Under the ACA: The ACA improved Medicare by offering free preventive services, annual wellness visits, and gradually closing the "donut hole" in prescription drug coverage.

  • Medicare Advantage Changes: Obamacare sought to make Medicare Advantage more cost-effective by adjusting payments to insurers and reducing subsidies.

  • Independent Oversight: The ACA proposed the Independent Payment Advisory Board to control Medicare costs, though it was never implemented and later repealed.

Eligibility Criteria

  • Obamacare Eligibility: Open to U.S. citizens and legal residents who are not covered by other public programs. Financial help is available depending on income and household size.

  • Medicare Eligibility: Available to U.S. citizens 65 and older, or younger individuals with disabilities or certain diseases, regardless of income.

  • Dual Eligibility: Some people qualify for both programs—Obamacare may provide additional coverage or subsidies for those already enrolled in Medicare.

Comparing Benefits

  • Obamacare Plans: These must include 10 essential health benefits, such as emergency services, maternity care, mental health treatment, and prescription drugs. Plans vary by coverage level (bronze to platinum) and include financial aid for those who qualify.


  • Medicare Coverage: Covers a more specific range of services for older adults and includes hospital (Part A), outpatient (Part B), prescription (Part D), and optional Medicare Advantage (Part C) plans.Life insurance is a crucial aspect of financial planning that provides financial support and peace of mind to your loved ones in the event of your passing. Understanding the ins and outs of life insurance can be overwhelming, but with the right tips and tricks, you can master this important investment for you and your family's future.
