ACA Marketplace basics

What is the Health Insurance Marketplace?

The government-run system where individuals and families shop for and enroll in private health plans — often with a subsidy that lowers the monthly cost.

How ACA Subsidies (Premium Tax Credits) Work

A subsidy (officially the Advance Premium Tax Credit) reduces your monthly premium based on your household income and size — it's calculated individually, not a flat discount.

What Is a Special Enrollment Period (SEP)?

A window outside of Open Enrollment when you can sign up for or change a Marketplace plan, triggered by a qualifying life event.

What Is Open Enrollment?

The annual window when anyone can enroll in or change a Marketplace plan, without needing a qualifying life event.

How Income Changes Affect Your Marketplace Coverage

Your subsidy is based on estimated income — a raise, a new job, or reduced hours can all change what you should be paying, so reporting changes as they happen matters.

Marketplace Eligibility: The Basics

Eligibility depends on residency, citizenship/immigration status, and not having access to other qualifying coverage — the details are specific enough that they need to be checked case by case.

Understanding your coverage

Deductible vs. Copay vs. Coinsurance

Three different ways you share the cost of care with your insurance — understanding each one changes how you read any plan's price tag.

What Is the Out-of-Pocket Maximum?

The most you'll pay for covered services in a plan year before your insurance starts covering 100% — the built-in ceiling that protects you from unlimited cost.

What Is a Provider Network?

The specific group of doctors, specialists, and hospitals a plan has contracted with — using a provider outside that group can cost significantly more, or not be covered at all.

HMO vs. PPO: What's the Real Difference?

HMOs generally require a primary care doctor and referrals, with little to no out-of-network coverage; PPOs offer more flexibility to see specialists directly and go out-of-network, usually for a higher premium.

PCPs and Specialists: How Referrals Work

Your primary care physician (PCP) is usually your first stop and, on many plans, the gatekeeper for specialist referrals — how strictly that's enforced depends on whether you have an HMO or a PPO.

How Prescription Drug Coverage Works

Each plan has its own formulary (drug list) and tier system — the same medication can cost very different amounts depending on the plan.

Preventive Care: What's Usually Covered at No Extra Cost

Most ACA-compliant plans cover a defined list of preventive services — like annual checkups and standard screenings — with no copay, coinsurance, or deductible, when you use an in-network provider.
