Short answer: Minimum essential coverage (MEC) is the basic type of coverage that satisfies the ACA’s individual coverage standard; minimum value (MV) is a higher bar meaning the plan pays at least 60% of expected costs and provides substantial inpatient and physician coverage. Large employers must offer MEC that provides minimum value to avoid the bigger employer-mandate penalty.
These two ACA terms are easy to confuse but mean different things.
Minimum essential coverage (MEC) is the broad category of coverage that counts as having insurance: employer plans, Medicare, Medicaid, Marketplace plans, and so on. For the employer mandate, an applicable large employer must offer MEC to at least 95% of full-time employees to avoid the larger “(a)” penalty.
Minimum value (MV) is a quality standard: a plan provides minimum value if it is expected to pay at least 60% of the total cost of covered services (a 60% actuarial value) and provides substantial coverage of inpatient hospital and physician services. To avoid the “(b)” penalty, the coverage an ALE offers must be both minimum value and affordable.
In short: MEC is “coverage exists”; minimum value is “the coverage is good enough.” A plan can be MEC without providing minimum value (e.g., some skinny plans), which is a compliance trap for large employers.
