Keep in mind that your neighbors or friends or relatives Part D plan may the the absolute best for them, but that does not mean it is the best for you. It depends on what drugs you take, what is on their formulary and what Tier it falls into, and whether the pharmacy's are preferred or not for those drugs. Also don't forget that while the government does not MAKE you take a part D plan out, if you do not take one out when you are eligible, or don't have other credible coverage, or don't have an advantage plan that also includes a drug plan, then you will be fined 1 percent per month from the time you were eligible for each month until you do take out a drug plan, and it is a LIFETIME penalty.
Many people think "well I don't take any drugs, so why should I want a drug plan?" So they wait lets say 10 years, and fall ill and need drugs and want a drug plan. Now their drug plan will be 120 percent higher than it could have been. It is figured against the national average drug plan which is about $33 per month, (varies by year) So while the penalty seems small on a monthly basis, it adds up after a few years, and it never goes away.
I always recommend that you take the cheapest drug plan you can get even if you don't need a drug plan. That is about $17 a month. Why the government says on the one hand "you don't have to do this" and on the other hand "but if you don't, we will punish you forever" is beyond me.. But many of the other rules don't seem fair to me. But no one asked me.
For those of you with advantage plans that include drug coverage, and most do, you don't have to worry about this. But this is something you will have to deal with if you have a supplement. You will want to take out a part D drug plan. Remember the Part D drug plan has nothing to do with your supplement insurance carrier or likely nothing to do with your agent either. I am not appointed with any of the drug companies and have nothing to do with drug plans other than helping folks to understand and choose one.
