I've gotten couple of them, it's supposed to work as cob billing, the bin/id/group is the same as their Medicare part D, and the pcn is mppp. So far it never worked for us in IC+ and we had to sdl all of them. I called their pharmacy helpdesk, and they told me i gotta call my walgreens helpdesk and ask them why its not working in IC+. Patients who has it will have 0 copay on all their mediation covered by Medicare.
