If you're looking for a Medicare Advantage plan, use:
www.ehealthmedicareplans.com
You don't have to give any personal information, just zip code. You can input your meds and your doctor(s) to see if they're part of the plan. You can compare all the MA plans in your area. You can check for Part B giveback under "monthly premium" or "Plan features". For example, in zip code 90001, V is covered at tier 3, $75 for 3 months. Remember to choose the .5 gram option,otherwise V will show as not covered.
(btw this particular plan also gives back the entire Part B premium!)
While we're on the subject, no responses to post 394850? I guess complaining is easier than proactivity.
