Continuing Coverage for Preexisting Conditions Act of 2020 This bill establishes severability between provisions relating to the requirement to maintain minimum essential health care coverage (i.e., the individual mandate) and other provisions of the Patient Protection and Affordable Care Act. Specifically, the bill provides that if the individual mandate is found to be illegal or incapable of being enforced, such findings do not affect the validity of other provisions relating to (1) the availability and renewability of coverage, or (2) the prohibitions against discriminatory coverage practices based on preexisting conditions or health status.
