Which major ACA change occurred after 2017?

• A. Medicaid expansion became a state option
• B. The subsidies for private plans were expanded nationwide
• C. The individual mandate was strengthened
• D. Health insurance marketplaces were eliminated

Answer: (A)

The key idea here is how the ACA’s implementation evolves in practice, especially who makes the big coverage decisions. Medicaid expansion being a state option reflects the ongoing federal–state dynamic at the heart of the law: while the ACA sets the framework, states decide whether to expand eligibility. Since this framework continues to drive coverage decisions after 2017, it remains a defining post-2017 aspect of how the ACA operates in real life. The other ideas don’t fit as well for this timeframe. Marketplaces were not eliminated, and the law did not see a strengthened individual mandate. Subsidies for private plans did expand in later years via separate legislation, but that change isn’t captured by a simple post-2017 shift labeled as Medicaid expansion becoming a state option.
