What is Plan G and what does it cover?

Quick Answer

Plan G is a Medigap (Medicare supplement) plan that covers most of the out-of-pocket costs Original Medicare does not pay, including the 20% coinsurance you owe after Medicare pays its share. The one cost it does not cover is the Part B deductible.

Detailed Explanation

Medigap plans are sold by private insurance companies to fill the gaps in Original Medicare. Plan G is one of the most comprehensive options available. After you pay the yearly Part B deductible (the amount you pay before Medicare kicks in for outpatient services), Plan G covers nearly everything else Original Medicare leaves on the table.That includes the Part A hospital deductible, your coinsurance for hospital stays, skilled nursing facility coinsurance, the Part B coinsurance (the 20% you would otherwise pay on doctor visits and outpatient care), and even emergency care during foreign travel. Once you meet that one deductible each year, your out-of-pocket costs for covered services are essentially handled.Plan G is popular because it offers predictability. You pay your monthly premium plus that one deductible, and from there you are largely protected from surprise bills on covered services. Premiums vary by carrier, your age, where you live, and whether you smoke, so it is worth comparing options. Plan G is not available to people who became eligible for Medicare on or after January 1, 2020 through a new-to-Medicare pathway for Plan F, but most people turning 65 today can still apply for Plan G. Always verify current benefits and pricing with a licensed agent.

How This Applies in Utah

In Utah, Plan G is offered by several carriers including SelectHealth, Regence BlueCross, UHC, Humana, Aetna, and others. Premiums can vary significantly between carriers for identical coverage, so comparing quotes is genuinely worth your time.

What This Means For You

For you, this means Plan G can protect you from large, unpredictable medical bills, leaving you with one predictable deductible per year and a monthly premium rather than ongoing cost uncertainty.

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.
