How do I compare worst-case costs across Medicare plans?

Quick Answer

To compare worst-case costs across Medicare plans, look at each plan's out-of-pocket maximum, not just the monthly premium. That ceiling tells you the most you could owe in a bad year before the plan covers 100% of covered costs.

Detailed Explanation

The premium is just the entry fee. The number that really matters when comparing plans is the out-of-pocket maximum, which is the most you'd have to pay in a single year before the plan picks up everything else for covered services. Medicare Advantage plans are required to have this cap. Original Medicare alone does not have one, which is why many people pair it with a Medigap (supplemental) policy.To do a real worst-case comparison, pull up each plan's Summary of Benefits and find three numbers: the monthly premium, the deductibles (what you pay before coverage kicks in), and the annual out-of-pocket maximum. Then do some rough math. Add your annual premiums to the out-of-pocket max. That total represents roughly how bad a year could get.Also check whether your regular doctors and any hospitals you'd want to use are in-network. Going out of network can blow past the in-network out-of-pocket max entirely on some plan types. And if you take prescriptions, run your specific drugs through the plan's formulary tool before you decide. A low premium plan with poor drug coverage can cost you far more in the end.Plan details vary by carrier and change each year, so always verify current figures during the Annual Enrollment Period or when you first sign up.

How This Applies in Utah

What This Means For You

For you, this means a plan with a higher monthly premium might actually cost less in a year where something serious happens, so it pays to look beyond the premium before choosing.

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.
