What gaps does Original Medicare leave me with?

Quick Answer

Original Medicare covers a lot, but it leaves you responsible for deductibles, coinsurance, and copays with no cap on out-of-pocket costs. It also doesn't cover most dental, vision, hearing, or prescription drugs.

Detailed Explanation

Original Medicare, meaning Part A and Part B, is solid foundational coverage. But it was never designed to cover everything, and the gaps can add up fast.The biggest one is that there is no out-of-pocket maximum. With most private insurance, your costs stop at some point each year. Original Medicare has no such ceiling. A long hospital stay or a serious illness could leave you with tens of thousands of dollars in cost-sharing, which is your share of the bill after Medicare pays its portion.Specifically, Part A has a deductible each benefit period, not just once a year. Part B covers 80 percent of most outpatient services, leaving you responsible for the other 20 percent with no cap. That 20 percent on a major surgery or ongoing specialist care can be significant.Beyond cost-sharing, Original Medicare doesn't cover prescription drugs. You need a separate Part D plan for that. Routine dental cleanings, eyeglasses, and hearing aids are also not covered, which surprises many people.Most people address these gaps by adding either a Medigap plan, sometimes called Medicare Supplement, which helps cover the cost-sharing, or by switching to Medicare Advantage, which bundles coverage and typically adds extra benefits. Each approach has tradeoffs worth understanding before you choose.

How This Applies in Utah

What This Means For You

For you, this means Original Medicare alone likely isn't enough coverage for most people, and choosing how to fill those gaps is one of the most important decisions you'll make at 65.

‍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.
