Monthly premium in Michigan for part D with no deductible is $88. That's $1056/year just to have the minimal coverage it offers. On top of that, you have copays that can be costly: Tier 1 Copay is $4; Tier 2 Copay is $35; Tier 3 Copay is $70; Tier 4/5 Coinsurance is 25% of retail cost of med. If most of your meds are Tier 1 you can afford the $4 and don't need insurance. Keep in mind if any drug you take isn't in their Formulary, they cover nothing. Also, note that some meds have quantity limits and some require pre-authorization. Now for the donut hole: Once the total cost (what you and the insurance paid) of your meds reaches $2,840 in any given year, it pays nothing (you pay 100%) until you reach $4,550 and then you still have a copay of $2.50 for generic and $6.30 or 5% coinsurance for non-generic. In certain situations one might save money compared to not having insurance but compared to employer sponsored prescription coverage (no donut hole there) it's a joke, especially since people on Medicare are old and take much more medicine than they did earlier in life.
