The Affordable Care Act remains in place. Plans bought during open enrollment have an effective date of January 1, 2019. A ruling by a Federal judge in Texas that the ACA is unconstitutional remains in the court system, and does not impact health plans bought by individuals in Pennsylvania for 2019. These plans bought on healthcare.gov, or ACA-compliant plans bought elsewhere, continue to have all the consumer protections provided by the ACA, including coverage for pre-existing conditions, prescription drugs, preventive care, mental health and substance use disorder.
Make sure you pay your initial premium before January 1 and your premiums each month to keep your coverage.
