How do I find the lowest total drug cost, not just the lowest premium?

Quick Answer

To find your lowest total drug cost, compare plans using Medicare's Plan Finder tool at Medicare.gov, entering your specific medications. Total cost includes the premium, your deductible, and what you'll pay at the pharmacy for each drug throughout the year.

Detailed Explanation

The premium is the part of a drug plan's cost that shows up most obviously, but it's rarely the whole story. Two plans with very different premiums can flip completely once you factor in the deductible, the tier placement of your specific drugs, and whether your preferred pharmacy is in-network or preferred.Medicare's Plan Finder at Medicare.gov is built exactly for this. When you enter your medications, including dosages and how often you take them, it calculates an estimated annual cost for each plan that includes the premium, the deductible, and your expected copays or coinsurance at the pharmacy. That total cost number is far more useful than the monthly premium alone.A few things to watch closely. First, check which pharmacy you'd use. Many plans charge less at preferred pharmacies, sometimes significantly less. Second, look at how each plan places your drugs on its formulary. A formulary is the plan's list of covered drugs and what you'll pay for each one. A drug on a higher tier costs more out of pocket. Third, consider whether any of your drugs require prior authorization or step therapy, which means the plan may require you to try a cheaper drug first.Plan details change every year, so it's worth reviewing your coverage during Medicare's Open Enrollment Period, which runs October 15 through December 7 each year.

How This Applies in Utah

A local independent Medicare agent in Utah can run this comparison with you using the same data and help you weigh total costs across plans available in your zip code, which matters especially in rural counties where plan availability is more limited.

What This Means For You

For you, this means skipping straight to the total annual cost estimate in Plan Finder, not the monthly premium, will give you a much more accurate picture of what you'd actually spend.

‍How Resting Sycamore Advisors Uses CMS Data

Our Commitment to Reliable Medicare Information

At Resting Sycamore Advisors, we work to provide accurate, current, and trustworthy information about Medicare Advantage, Medicare Part D, and Special Needs Plans.

To do that, we use data published by the Centers for Medicare & Medicaid Services (CMS), which is the official source for Medicare plan and enrollment information.

CMS Data Sources We Rely On

Our Medicare plan pages and comparison tools are powered by CMS datasets, including:

  • Medicare Advantage and Part D Landscape Files for annual plan availability and benefit details
  • Plan Benefits Package (PBP) Files for detailed benefit and coverage information
  • Part C and Part D Performance Data for quality ratings and plan performance measures
  • Monthly Enrollment Data for enrollment counts by contract, plan, state, and county

When possible, we link to the original CMS resources so you can review the source material directly.

How Often We Update Our Data

We follow the CMS release schedule and update our website as new data becomes available.

Annual Plan Year Updates (September)

We load new plan year Landscape and PBP files before the Medicare Annual Enrollment Period (October 15 through December 7). We also monitor CMS.gov for updates or revisions and refresh our content when needed.

Mid-Year Updates

We update enrollment and performance data as CMS publishes revised files, which are typically released monthly or quarterly.

Ongoing Maintenance

We routinely monitor CMS announcements for corrections, reissued files, or other changes and update our pages accordingly.

Each plan page includes a Last Accessed date so visitors can see when the source information was most recently reviewed.

How We Prepare CMS Data for Our Website

CMS data can be difficult to read in raw form. To make it easier to use, we format and organize the data for clarity.

This includes:

  • Standardizing plan identifiers such as contract ID, plan ID, and segment
  • Normalizing terminology so common Medicare terms are presented consistently
  • Organizing plan information by state, county, and ZIP code to match how people shop for coverage

All data values come from CMS. We do not change the underlying values beyond formatting, organization, and presentation.

Version Tracking and Transparency

We keep internal records of the CMS dataset versions used on our site.

Major Version History

  • Current Version: CY2025 Medicare Advantage and Part D Landscape Files (v1.0, published October 2025)
  • Prior Version: None. Resting Sycamore Advisors first began publishing structured Medicare plan information in March 2025

If CMS issues corrected or revised files, we update our website to reflect the latest available version.

Important Limitations

Please keep the following in mind:

  • CMS is the official source of truth. For enrollment and coverage decisions, always confirm details with Medicare.gov or 1-800-MEDICARE.
  • Data timing can vary. Enrollment and performance updates may appear on our website a few weeks after CMS publishes changes.
  • Plan details can change. Plan availability, costs, and benefits may change. Always verify current details directly with the plan provider.
