How do I check whether my doctor accepts Medicare and is in-network?

Quick Answer

To check if your doctor accepts Medicare, call their office and ask directly. To check if they're in-network for a specific plan, use that plan's online provider directory or call the plan's member services number. These are two different questions with different answers.

Detailed Explanation

This is actually two separate questions that often get mixed up, and the difference matters.Accepting Medicare means the doctor has agreed to bill Medicare at all. Most doctors in the U.S. do, but not all. A doctor who accepts Medicare as a patient is called a Medicare-participating provider. Some doctors accept Medicare but only at a limited rate, called non-participating providers, which can result in extra charges for you. A small number opt out entirely and cannot bill Medicare at all. The simplest way to check: call the office and ask if they accept Medicare.Being in-network is a separate question that only applies if you have a Medicare Advantage plan (Part C). Medicare Advantage plans are run by private insurance companies, and each one has its own network of doctors and hospitals. A doctor who accepts Medicare may still be out-of-network for your specific Advantage plan, which usually means higher costs or no coverage at all.To check in-network status for a Medicare Advantage plan, go to the plan's website and use their provider directory, or call the member services number on your insurance card. These directories can change during the year, so it's worth confirming directly with both the plan and the doctor's billing office before scheduling care.Original Medicare (Parts A and B without an Advantage plan) doesn't use networks in the traditional sense, so any Medicare-participating doctor nationwide will accept your coverage.

How This Applies in Utah

If you're on a Medicare Advantage plan in Utah, major carriers like SelectHealth, Regence, and others each maintain separate provider networks. Intermountain Health and University of Utah Health are large systems that may or may not be in-network depending on your specific plan, so always verify before assuming.

What This Means For You

For you, this means a quick phone call to both your doctor's office and your insurance plan before an appointment can save you from an unexpected bill 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.
