Medicaid vs the ACA Marketplace

The basic difference

Medicaid is a public health coverage program for people with lower incomes, run jointly by the federal government and each state, usually with very low or no premiums. The ACA Marketplace is where you buy private health plans, sometimes with a premium tax credit that lowers your cost. They serve different income ranges and work differently.

How your state affects it

Whether you qualify for Medicaid depends heavily on your state, because states set their own income limits and some have expanded Medicaid while others have not. In states that did not expand, some lower-income adults fall into a coverage gap, earning too much for Medicaid but facing higher marketplace costs.

• Expansion states cover more low-income adults through Medicaid
• Non-expansion states can leave a coverage gap
• Marketplace subsidies help fill some, but not all, of that gap

How to know which is right for you

You do not have to figure this out alone. When you apply, the system checks Medicaid eligibility first, and if you do not qualify it shows your marketplace options. A licensed agent can walk you through both, explain your state’s rules, and make sure you end up on the coverage you actually qualify for.
