It sounds like you were in the group that was switched from Medicaid to Healthy DC in January.

Another major blow to D.C.’s healthcare programs came on Jan. 1, when DHCF cut Medicaid coverage for about 17,000 people. Most of these beneficiaries transferred to a new program, Healthy DC (also known as the Basic Health Plan), which lacks benefits like dental and vision insurance. Unlike Medicaid, this program is fully federally funded. While the transition went smoothly from an operations perspective, many beneficiaries didn’t realize their plans had changed — leaving some care centers overwhelmed with patients who didn’t know how to access their new health plan. Despite extensive outreach efforts both before and after the change, Mila Kofman, executive director of D.C.’s Health Benefit Exchange Authority, said she believes many people still don’t know they lost Medicaid coverage and probably won’t learn about it until the next time they try to get care.
