Final answer:
The Minimum Essential Coverage (MEC) that integrates with the Health Savings Account (HSA) is the high-deductible health plan (HDHP), which is a health insurance policy meeting requirements under the Affordable Care Act and allows individuals to save money for medical expenses in a tax-advantaged account.
Step-by-step explanation:
The MEC that integrates with the HSA is referring to the Minimum Essential Coverage integrating with the Health Savings Account. The Affordable Care Act requires individuals to have health insurance coverage, and the Minimum Essential Coverage (MEC) represents the type of health insurance policy that meets the requirements under the law. Meanwhile, a Health Savings Account (HSA) is a tax-advantaged medical savings account available to taxpayers who are enrolled in a high-deductible health plan (HDHP). The HDHP is one form of MEC that is compatible with HSAs. Subscribers of MECs like HDHPs can save money pre-tax in an HSA to pay for qualifying medical expenses.
