There's no single best Medicare plan for expensive prescriptions. The right choice depends on which drugs you take, which tier those drugs land on in a given plan's formulary, and what your total out-of-pocket costs would be across the year.
If you're managing high prescription costs, the plan structure matters a lot more than the premium. Every Medicare drug plan uses a formulary, which is a list of covered drugs organized into cost tiers. A medication that's on a low tier in one plan might be on a high tier, or not covered at all, in another. So the only real way to find a plan that works well for your prescriptions is to compare plans using your actual drug list. Medicare's Plan Finder tool at medicare.gov lets you enter your medications and see estimated annual costs side by side. In Utah, carriers like SelectHealth, Regence, UHC, Humana, and others each offer plans with different formularies and cost structures, and those change every year during Open Enrollment. Beyond formulary placement, look at the plan's deductible, copays at your preferred pharmacy, and whether your pharmacy is in-network. Also worth knowing: Medicare's out-of-pocket cap for drug costs took effect in 2025, which provides real protection for people on expensive medications. A licensed Medicare agent or a free SHIP counselor can walk through your specific drugs with you so you're comparing total cost, not just the monthly premium.




Utah's ADRC runs free Medicare counseling through the SHIP program. A counselor can help you run a side-by-side comparison of Utah drug plans based on your actual prescriptions at no cost to you. If you're on a limited income, the Extra Help program (also called the Low Income Subsidy) can significantly reduce Part D costs and is worth checking.
For you, this means looking beyond the monthly premium and pulling up your actual drug list before choosing a Part D or Medicare Advantage plan, because the formulary tier your medications land on will likely drive more of your annual cost than the premium will.
