What do people usually forget to check before enrolling in Medicare?

Quick Answer

People most commonly forget to check whether their current doctors accept the plan they're enrolling in, and whether their prescriptions are covered at a reasonable cost under that plan's drug formulary.

Detailed Explanation

Two things trip people up more than anything else. The first is doctor access. With Medicare Advantage plans, your doctors have to be in the plan's network or you may pay significantly more, or nothing gets covered at all outside emergencies. People assume their longtime doctor accepts every Medicare plan, and that's often not the case. It's worth calling the doctor's office directly and asking if they accept the specific plan you're considering, not just Medicare in general. The second is prescription drug coverage. Every Part D drug plan and Medicare Advantage plan with drug coverage has a list of covered medications called a formulary. Even if your drug is on the list, it may be in a higher cost tier that makes your monthly costs much higher than expected. Before you enroll, run your exact prescriptions through Medicare's plan finder at medicare.gov to see what each plan would actually cost you over a full year. These two checks take maybe an hour and can save you thousands.

How This Applies in Utah

In Utah, network access matters a lot depending on which health system your doctors use. Intermountain Health and University of Utah Health each have different relationships with different carriers, so a plan that works well for one person's care team may not work for another's. Checking network fit before you enroll is especially important here.

What This Means For You

For you, this means taking 30 to 60 minutes before enrollment to verify your doctors are in-network and your medications are covered at an affordable tier can prevent costly surprises that are difficult to fix until the next enrollment period.

‍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.
