California Gov. Gavin Newsom announced broad plans to the state’s health care system almost immediately after taking the oath of office. Larry Levitt, Senior Vice President for Health Reform at KFF, answers three questions about what the plan's individual mandate and expanded subsidies could mean for the state and nationwide.
This analysis looks at how many of the remaining uninsured are eligible for premium subsidies that are large enough to cover the entire cost of a bronze plan, which is the minimum level of coverage available on the Marketplaces. It estimates 27% of uninsured individuals who could shop on the ACA Marketplace, or 4.2 million people nationwide, are eligible to purchase a bronze plan with $0 premiums after subsidies in 2019.
KFF analysis of Healthcare.gov data from marketplace plans on the federal insurance exchanges shows that despite the changes to the Affordable Care Act in recent years, deductibles for those with low incomes have remained relatively stable since 2017.
Karen Pollitz answers three questions on the Trump administration's recent changes to the ACA Section 1332 state innovation waiver guidelines and the implications for consumers and state marketplaces in our new “Ask KFF” feature.
The Health Insurance Marketplace Calculator, updated with 2019 premium data, provides estimates of health insurance premiums and subsidies for people purchasing insurance on their own in health insurance exchanges (or “Marketplaces”) created by the Affordable Care Act (ACA). With this calculator, you can enter your income, age, and family size to estimate your eligibility for subsidies and how much you could spend on health insurance.
Short-term health insurance plans are able to charge premiums 54 percent lower than ACA-compliant plans, by excluding pre-existing conditions and severely limiting benefits.
In health insurance systems designed to protect people with pre-existing conditions and guarantee availability of coverage regardless of health status, countervailing measures are also needed to ensure people do not wait until they are sick to sign up for coverage (as doing so would drive up average costs for other enrollees).
This tracker monitors preliminary 2019 premiums in the Affordable Care Act’s marketplaces as insurers file rate information with state regulators. It shows preliminary premium information in a major city in each available state for the lowest-cost bronze plan and “benchmark” silver plan, which is used to determine the size of the premium tax credits available to low- and moderate-income enrollees. The tracker also shows how those premiums are changing from 2018 and what a 40-year-old enrollee making $30,000 annually would pay before and after available tax credits.
This brief estimates the share of adults with pre-existing conditions by metropolitan and micropolitan statistical area (MMSA), and finds that in some areas, nearly four in ten have so-called declinable medical conditions that could lead to denials of individual insurance coverage based on pre-ACA underwriting guidelines.
Enrollment in the individual insurance market continued to shrink in the first quarter of 2018, declining by 12 percent compared to the first quarter of 2017, according to a new analysis from the Kaiser Family Foundation.
