Do I need Original Medicare first before I can choose a plan?

Quick Answer

Yes. Original Medicare, which includes Part A (hospital coverage) and Part B (outpatient coverage), is the foundation. You need to be enrolled in both Part A and Part B before you can join a Medicare Advantage plan, and Part A or Part B before you can add a standalone Part D drug plan.

Detailed Explanation

Think of Original Medicare as the base layer. Part A covers inpatient hospital stays, skilled nursing facility care, hospice, and some home health services. Part B covers doctor visits, outpatient procedures, preventive care, and medical equipment. Together, they form what Medicare calls Original Medicare.Once you have Part A and Part B, you have choices. You can stay with Original Medicare and add a standalone Part D plan for drug coverage, a Medigap policy to help with out-of-pocket costs, or both. Or you can enroll in a Medicare Advantage plan, which is a private plan approved by Medicare that bundles Part A and Part B benefits together, often with Part D included.But here's the key point: Medicare Advantage doesn't replace your enrollment in Original Medicare. You stay enrolled in Medicare; the Advantage plan just delivers your benefits. If you leave that plan, you go back to Original Medicare automatically.If you're still working at 65 and have employer coverage, you may be able to delay Part B without penalty. That's a separate decision that depends on your employer's plan size and a few other factors. But if you're ready to use Medicare, getting Part A and Part B set up first is always the starting point.

How This Applies in Utah

What This Means For You

For you, this means you can't skip straight to a plan without enrolling in Medicare first, so getting Part A and Part B in place is the step that opens all your other options.

‍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.
