MEC vs. HDHP: Understanding the Differences in ACA-Compliant Health Insurance Plans

The Affordable Care Act (ACA) has revolutionized the health insurance landscape in the United States. One of the key provisions of the ACA is the establishment of minimum coverage standards that health insurance plans must meet to be considered compliant. Two types of plans that have emerged under the ACA, Medicare Secondary Payer (MSP) Excepted Coverage (MEC) plans and High-Deductible Health Plans (HDHPs) with Health Savings Accounts (HSAs), have garnered attention due to their distinct features.

MEC Plans: A Limited Option

MEC plans are designed to provide basic, limited coverage that supplements Medicare or other primary coverage. They are often offered by employers as a cost-effective option for employees who are also eligible for Medicare. However, MEC plans have several limitations, including:

– Low Annual Coverage Limit: MEC plans have an annual coverage limit, typically $2,500-$3,000. This means that the plan will only cover healthcare expenses up to that amount, after which the individual is responsible for paying for any remaining costs.

– No Out-of-Pocket Maximum: Unlike other ACA-compliant plans, MEC plans do not have an out-of-pocket maximum. This means that individuals with MEC plans could be liable for unlimited healthcare expenses above the annual coverage limit.

– Other Restrictions: MEC plans may also have other restrictions, such as limits on preventive care services and coverage for specific types of medical conditions.

HDHPs with HSAs: A High-Deductible Option

HDHPs are designed to offer higher deductibles than traditional health insurance plans, but they also come with tax-advantaged Health Savings Accounts (HSAs). HSAs allow individuals to contribute pre-tax dollars to cover qualified healthcare expenses.

– High Deductible: HDHPs typically have deductibles ranging from $2,000 to $7,000 for individuals and $4,000 to $14,000 for families.

– Out-of-Pocket Maximum: HDHPs must have an out-of-pocket maximum, which is the most an individual is responsible for paying for covered healthcare expenses in a given year. This limit includes the deductible, coinsurance, and other out-of-pocket costs.

– Health Savings Accounts (HSAs): Individuals with HDHPs can contribute pre-tax dollars to HSAs, which can be used to cover healthcare expenses, including deductibles and coinsurance. HSAs accumulate over time and can be used for healthcare expenses during retirement.

Choosing the Right Plan for You

The choice between a MEC plan and an HDHP with an HSA depends on individual circumstances and financial goals. MEC plans may be suitable for individuals who have access to other forms of primary coverage, such as Medicare, and are looking for a limited, low-cost option. HDHPs with HSAs can be beneficial for individuals who are willing to pay a higher deductible to reduce monthly premiums and save money in the long term through HSAs.


MEC and HDHP plans are both ACA-compliant, but they offer different levels of coverage and financial implications. Understanding the distinctions between these plans can help individuals make informed decisions when selecting health insurance coverage that meets their needs and financial situation.
