What does Medicare Part B cover?

Quick Answer

Medicare Part B covers doctor visits, outpatient care, preventive services like screenings and vaccines, and medically necessary services such as lab tests, imaging, and durable medical equipment. You typically pay 20% of the Medicare-approved amount after meeting your annual deductible.

Detailed Explanation

Part B is the outpatient side of Original Medicare. It covers two broad categories: medically necessary services and preventive care.Medically necessary services include things like visits to your primary care doctor or specialist, outpatient surgery, mental health care, physical therapy, lab work, X-rays, MRIs, and durable medical equipment (walkers, wheelchairs, CPAP machines, and similar items). Basically, if a doctor orders it and Medicare deems it necessary to diagnose or treat a condition, Part B usually covers it.Preventive care includes annual wellness visits, flu shots, certain cancer screenings, diabetes screenings, and cardiovascular disease screenings. Many of these come with no cost-sharing if your doctor accepts Medicare assignment, meaning they've agreed to Medicare's approved payment rates.The standard setup is that Medicare pays 80% of the approved amount and you pay the remaining 20%, with no out-of-pocket cap on that 20%. That's why many people pair Part B with either a Medigap supplement or a Medicare Advantage plan, both of which can reduce or cap what you owe. Part B has a monthly premium and an annual deductible, and those amounts can change each year, so it's worth verifying current figures at medicare.gov or with a licensed agent.

How This Applies in Utah

What This Means For You

For you, this means most of your regular doctor visits and outpatient care will be covered, but you'll want a plan that helps cover that 20% coinsurance since there's no annual limit on what that could add up to.

‍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.
