What were some exceptions to the ACA's healthcare reform deadline?

The correct choice highlights individuals eligible for Medicaid Expansion as an exception to the ACA's healthcare reform deadline. Under the Affordable Care Act, states were given the option to expand Medicaid coverage to individuals with incomes up to 138% of the federal poverty level. This expansion was initially put in place to ensure that low-income individuals and families had access to affordable healthcare.

The ACA established a timeline for implementing various components of the healthcare reforms, but states had flexibility regarding whether and when to expand Medicaid. As a result, those eligible for Medicaid Expansion did not face the same deadlines as other groups regarding acquiring health insurance. This characteristic of state discretion provided a significant exception, allowing some individuals to obtain coverage even beyond standard deadlines set by federal mandates.
