I have spent the last 3 months since going on Medicare researching the ins and outs of medigap policies. After changing my plan and provider 3 times while in my initial 6 month period, I've ended up with the AARP/UHC medigap plan N. I started with a WPS policy equivalent to a plan F for $179/mth. After reading how plan F is going away in 2020 and premiums could skyrocket I went with their plan G equivalent for $167/mth. Now I've ended up with the AARP plan N for $108/mth($106 with EFT withdrawal and the 27% discount which decreases 3% per year). The ONLY difference between the "G" and the "N" plans are the $20 copay to the Dr. and the $50 emerg. room copay...and not everyone seems to know this, in Wisconsin you can add a rider that covers the Part B excess payments. So if you live in Wis. and are looking at a Plan G or N, don't be afraid of the N because it's basically just a Plan G with the copays but at a lower premium.
