Health Insurance Basics

The five cost terms you must know: Premium is what you pay every month whether you use care or not. Deductible is what you pay out-of-pocket before the plan starts sharing costs. Copay is a fixed dollar amount for a specific service (like $30 for a primary care visit). Coinsurance is your percentage share of costs after the deductible (often 20% or 30%). Out-of-pocket maximum is the annual ceiling — once you hit it, the plan pays 100% of covered in-network care for the rest of the year.

Metal tiers describe the plan's actuarial value — the percentage of average medical costs the plan covers. Bronze covers about 60% (low premium, high deductible), Silver 70% (mid-range, and the only tier where cost-sharing reductions apply for lower-income households), Gold 80% (higher premium, lower deductible), and Platinum 90% (highest premium, lowest out-of-pocket).

Network types: HMO requires you to use in-network providers and get referrals from a primary care doctor; premiums are lower. PPO lets you see out-of-network providers at higher cost and skip referrals. EPO is HMO-style network rules without the referral requirement. POS is a hybrid. In Florida, HMO networks dominate on the marketplace — always confirm your doctors are in-network before enrolling.

ACA subsidies: the Advanced Premium Tax Credit (APTC) lowers monthly premium based on household income. Cost-Sharing Reductions (CSR) lower deductibles and out-of-pocket costs, but only on Silver plans and only for households under about 250% of the federal poverty level. Enhanced subsidies currently extend above 400% FPL — check what applies to your household.

The total-cost math that matters: Monthly premium × 12 + expected medical spending (up to the out-of-pocket max) = your worst-case annual cost. Compare that number across plans — not just premium. Bronze often looks cheapest until you have a hospital stay.

Special enrollment triggers in Florida: losing job-based coverage, marriage, divorce, birth or adoption, moving to a new coverage area, or a change in income that affects subsidy eligibility. You have 60 days from the qualifying event to enroll.

HSA-eligible plans: high-deductible health plans (HDHPs) pair with a Health Savings Account. Contributions are pre-tax, growth is tax-free, and qualified withdrawals are tax-free — one of the strongest tax vehicles in the code for healthy households.
