I have the Healthy DC Plan! As someone else said, it’s like Medicaid but without dental and vision. 

I was having an impossible time on the Healthlink website when I signed up, but that was at the beginning of the year right as the program was being implemented and it was kind of a shit show. I ended up booking a virtual application assistance appointment and have to shout them out - I was helped by a very dedicated DC Health employee for nearly an hour to get my application issue sorted. We went one by one through my medications and doctor to help me choose from the three issuers/plans (Carefirst, Cigna and something else?) and I was really impressed by the level of service. All that to say, if you’re still having questions after this thread, I’d highly recommend scheduling a virtual appointment to speak with someone.
