"No Wrong Door" (NWD) is a system that allows consumers to apply for health insurance through different agencies, and then seamlessly routes them to the program for which they qualify. We find that over the course of a year under the Affordable Care Act, NWD would prevent 36,000 Connecticut residents from losing health insurance coverage for at least part of the year. Connecticut's leaders have committed to full implementation of NWD by the end of 2015. If this commitment is fulfilled, significant gains will result for both state government and residents. However, monitoring implementation in the transition period is critical.
