Can I go back to Original Medicare after being on Medicare Advantage?

Quick Answer

Yes, you can switch back to Original Medicare from a Medicare Advantage plan, but timing matters and there are specific enrollment windows when this is allowed.

Detailed Explanation

You are not locked into Medicare Advantage forever. Each year during the Annual Enrollment Period, which runs from October 15 through December 7, you can drop your Medicare Advantage plan and return to Original Medicare, with coverage starting January 1. There is also a Medicare Advantage Open Enrollment Period from January 1 through March 31 each year, which lets you make one switch, including going back to Original Medicare. Outside of those windows, you generally need a Special Enrollment Period triggered by a qualifying life event to make changes. One thing to plan for when switching back is Medigap coverage. Medigap, also called Medicare Supplement insurance, helps cover the out-of-pocket costs that Original Medicare doesn't pay. In most states, if you've been on Medicare Advantage for more than 12 months, insurers are not required to sell you a Medigap plan and can use medical underwriting, meaning they can consider your health history. Utah follows federal baseline rules here, so this is a real consideration. If you're thinking about switching back, talk to an agent before you do it so you understand your Medigap options first.

How This Applies in Utah

In Utah, Medigap plans are sold by carriers including SelectHealth, Regence BlueCross, Humana, and others. Since Utah does not have additional state protections beyond the federal guaranteed issue rules, it is especially important to understand your Medigap eligibility before dropping a Medicare Advantage plan.

What This Means For You

For you, this means switching back to Original Medicare is possible, but making the move without checking your Medigap options first could leave you with higher out-of-pocket costs and limited ability to get supplemental coverage later.

‍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.
