No. BCBS AL/TN refer to their traditional Medicare Medigap as "C+". It is not an Advantage plan. They do have one, called "Blue Advantage," which they push because it's so profitable. They make their money basically by denying coverage, since the final decision on treatment lies with the bureaucrats at the Advantage company, rather than with your doctor. Since people probably won't listen to the report you and I did, the victim developed melanoma on his ear and ran into delay after delay because his Advantage company kept delaying treatment until it was as large as a dime. When he tried to leave his Advantage company and re-sign with traditional Medicare Medicap, he found that that was the only part of Medicare which can consider pre-existing conditions into account, so his Medigap premium was prohibitive. IOW, Advantage is a one-way road, if your health goes bad. Then it becomes a trap you can't get out of. I believe most people think they can leave Advantage at any time and go back to traditional Medigap. Turns out that's not true...
