What would my costs look like if I needed surgery or chemo on Medicare?

Quick Answer

Surgery and chemotherapy can cost thousands under Medicare, depending on whether you have Original Medicare alone, a supplement, or a Medicare Advantage plan with an out-of-pocket maximum.

Detailed Explanation

The honest answer is that your costs depend heavily on what kind of Medicare coverage you have, not just Medicare itself.With Original Medicare alone and no additional coverage, you'd pay a 20 percent coinsurance, which means 20 percent of the Medicare-approved amount, for most outpatient services including chemotherapy. There's no cap on that. A $100,000 course of treatment could leave you with $20,000 or more in bills. Hospital stays have a deductible per benefit period, and costs increase the longer you're admitted.If you have a Medicare Supplement plan, often called Medigap, it covers most or all of that 20 percent coinsurance. Some plans also cover the hospital deductible. The tradeoff is a higher monthly premium, but your exposure in a serious illness year is much lower and more predictable.With a Medicare Advantage plan, you'll have an annual out-of-pocket maximum. Once you hit that cap, the plan covers 100 percent of covered services for the rest of the year. That ceiling matters enormously for surgery or chemo. However, copays and coinsurance add up fast on the way to that limit, and costs vary significantly by plan. Always check the specific plan's Summary of Benefits before enrolling, since these figures change year to year.

How This Applies in Utah

If you're receiving cancer treatment through Huntsman Cancer Institute at University of Utah Health or an Intermountain facility, verify that your specific plan covers those providers before you're mid-treatment. Network gaps during serious illness are among the most stressful coverage problems Utah residents encounter.

What This Means For You

For you, this means a major diagnosis is the moment your plan choice either protects you financially or exposes you to costs that can reach tens of thousands of dollars, so it's worth understanding your out-of-pocket exposure before you need the care.

‍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.
