How ACA Plans Work for Part-Time Workers in St. Mary's County

The Affordable Care Act (ACA) created health insurance marketplaces where individuals and families can purchase health coverage. In Maryland, this marketplace is called Maryland Health Connection. These plans are guaranteed-issue, meaning you cannot be denied coverage or charged more due to pre-existing conditions. For part-time workers in St. Mary's County, Maryland Health Connection is often the best path to comprehensive health insurance. ACA plans are categorized into metal tiers: Bronze, Silver, Gold, and Platinum. These tiers indicate how you and your plan share costs:

Bronze: Lowest monthly premiums, highest out-of-pocket costs when you need care. Best for those who rarely visit the doctor.
Silver: Moderate premiums and out-of-pocket costs. If your income is between 100% and 250% of the Federal Poverty Level (FPL), Silver plans offer extra subsidies called Cost-Sharing Reductions (CSRs), which further lower your deductibles, copays, and out-of-pocket maximums.
Gold: Higher monthly premiums, lower out-of-pocket costs. Good for those who expect to use medical services frequently.
Platinum: Highest premiums, lowest out-of-pocket costs. Pays for most of your medical expenses.

Regardless of your work status, you can qualify for premium tax credits if your household income falls between 100% and 400% of the FPL. These credits directly reduce your monthly premium, making plans more affordable.

Eligibility and Subsidies for Part-Time Employees

Your eligibility for financial assistance through Maryland Health Connection is determined by your household income relative to the Federal Poverty Level (FPL). For 2026, here's a general guide:

Below 138% FPL: You may qualify for Maryland Medicaid (HealthChoice), which provides comprehensive health coverage with little to no cost. Maryland expanded Medicaid in 2014, ensuring coverage for low-income adults.
100% to 400% FPL: You are eligible for premium tax credits, which lower your monthly health insurance payments. The amount of the credit depends on your income, household size, and the cost of the benchmark Silver plan in your area.
100% to 250% FPL: In addition to premium tax credits, you may qualify for Cost-Sharing Reductions (CSRs) if you choose a Silver plan. CSRs reduce your deductibles, copayments, and out-of-pocket maximums, making healthcare more affordable when you use it.

It's important to accurately report your estimated annual income when applying through Maryland Health Connection to ensure you receive the correct amount of financial assistance. If your income changes during the year, update your application to adjust your subsidies.

Understanding Your Health Plan Options in St. Mary's County

In St. Mary's County, residents have access to a variety of health plan structures through Maryland Health Connection. These include:

Health Maintenance Organization (HMO): These plans typically have lower premiums and require you to choose a primary care provider (PCP) within the network. Your PCP coordinates all your care and provides referrals to specialists.
Preferred Provider Organization (PPO): PPO plans offer more flexibility. You don't need a referral to see a specialist, and you can typically see out-of-network providers for a higher cost. PPO plans ARE available on-exchange in Maryland, including in St. Mary's County, through carriers like CareFirst of Maryland and CareFirst BlueChoice.
Exclusive Provider Organization (EPO): EPO plans are similar to HMOs in that they generally don't cover out-of-network care, except in emergencies. However, they usually don't require referrals to see specialists within their network.

When choosing a plan, consider your healthcare needs, preferred doctors, and budget. If you have specific providers you want to keep, check if they are in the plan's network before enrolling.
