Your Guide to Navigating the Medicare Physician Fee Schedule Tool

The Centers for Medicare & Medicaid Services (CMS) physician fee schedule tool enables healthcare professionals and community-based organizations to access detailed payment data for a wide range of Original Medicare services. For providers who need accurate CMS reimbursement rates by CPT code for Medicare, this tool serves as an essential resource for reviewing current payment amounts and billing guidelines.

The Centers for Medicare & Medicaid Services (CMS) revises the physician fee schedule (PFS) annually. These yearly updates ensure physicians and community-based organizations (CBOs) can use a centralized search platform to review the latest reimbursement rates for services covered under Original Medicare (Part A and Part B). Staying informed about CMS reimbursement rates by CPT code for Medicare is critical for maintaining compliant billing practices and accurate revenue cycle management.

What is the PFS?

The PFS is the primary payment mechanism Medicare uses to reimburse healthcare professionals who participate in the program. Medicare relies on the PFS when issuing payment for the following Original Medicare services:

• diagnostic tests
• radiology services
• services provided by auxiliary personnel, like nurses, or by nonphysician practitioners, like nurse practitioners
• professional services by physicians and other healthcare professionals in a private practice

Understanding how these services are valued under the PFS helps providers interpret CMS reimbursement rates by CPT code for Medicare and anticipate how changes in relative value units (RVUs) or geographic adjustments may affect payment.

A note on Medicare Advantage

Medicare Advantage (Part C) plans may set reimbursement amounts that differ from those listed in the PFS. Providers should verify payment rates, prior authorization rules, and coverage policies directly with each plan to avoid billing discrepancies.

About the PFS lookup tool

CMS offers a PFS lookup tool that allows physicians and CBOs to retrieve Medicare payment information for more than 10,000 services. The tool supports detailed searches related to:

• payment policies
• pricing
• associated relative value units (RVUs), used to help determine payment for physicians

Because RVUs and geographic practice cost indices (GPCIs) directly influence CMS reimbursement rates by CPT code for Medicare, reviewing this information is especially important for practices operating in multiple regions.

CBOs may also rely on the lookup tool to confirm reimbursement rates for specific covered services, such as:

• diabetes self-management training (DSMT)
• chronic care management (CCM)
• health behavior assessment and intervention (HBAI) services

For providers who want an additional way to estimate payments and compare allowable amounts, tools like the Medicare fee schedule 2025 calculator can complement the official CMS lookup system.

PFS example 1

The steps below demonstrate how to navigate the PFS lookup tool in a practical scenario.

Visit the PFS lookup tool overview page and select the “Begin Search” button. You will first be directed to the license agreement for use of current procedural terminology. Scroll to the bottom and click “Accept.” After accepting the terms, you will be taken to the main search interface.

In this example, we will look up the reimbursement rate for group DSMT to better understand CMS reimbursement rates by CPT code for Medicare in a real-world billing situation.

Dropdown options in PFS lookup tool

The PFS lookup tool includes dropdown selections for:

• year
• type of information pricing information payment policy indicators relative value units geographic practice cost index
• HCPCS code and criteria single code list of codes range of codes
• modifier
• Medicare Administrative Contractor (MAC) option national payment amount specific MAC specific locality all MACs

Follow these steps for this example:

1. Confirm that the current year (2025) is selected.
2. Under type of information, choose pricing information.
3. For the HCPCS criteria, select single HCPCS code, then enter G0109.
4. Modifiers reflect circumstances that may adjust how a service is delivered without changing its definition. Select all modifiers.
5. For the MAC option, choose national payment amount.
6. Click Search Fees.

Search results

The results page displays extensive payment data. For this illustration, focus on the non-facility rate shown in the table.

The designation “non-facility” indicates the service was performed in an office setting. A “facility price” typically applies when services are rendered in a hospital or ambulatory surgical center, where overhead costs differ.

The designation “non-facility” indicates the service was performed in an office setting. A “facility price” typically applies when services are rendered in a hospital or ambulatory surgical center, where overhead costs differ.

We are reviewing the non-facility amount because this DSMT service is generally provided on an outpatient basis and covered under Medicare Part B.

The lookup shows that non-facility group DSMT is reimbursed at $15.20 per person, per 30 minutes.

These services may involve coinsurance. For most Part B services, beneficiaries are responsible for 20% of the Medicare-approved amount, while Medicare covers the remaining 80%. Understanding this cost-sharing structure is important when counseling patients about their financial responsibility.

PFS example 2

In this second example, we will adjust the search criteria. Instead of entering a single HCPCS code, we will search for two: the group DSMT code G0109 and the individual DSMT code G0108. Both services are billed in 30-minute increments.

This time, we will narrow the results to a specific geographic area to demonstrate how locality influences CMS reimbursement rates by CPT code for Medicare. For this scenario, we will select the Los Angeles region.

Use the following steps:

1. Ensure the year remains (2025).
2. For type of information, select pricing information.
3. Under HCPCS criteria, choose list of HCPCS codes.
4. Two fields will appear. Enter G0108 in the first box and G0109 in the second.
5. Select all modifiers.
6. For the MAC option, choose specific locality.
7. From the MAC locality dropdown, select 0118218 Los Angeles-Long Beach-Anaheim.

Search results

The results now display payment amounts for both individual and group DSMT, along with the specified MAC locality information.

In this locality, the non-facility rate for individual DSMT is $58.26 per 30 minutes. For group DSMT, the non-facility rate is $16.76 per person per 30 minutes.

This comparison highlights how geographic adjustments can impact reimbursement and why it is essential to verify CMS reimbursement rates by CPT code for Medicare based on the service location.

Finding help

If you need additional guidance using the PFS lookup tool, CMS provides a quick reference guide that walks users through each step of the search process.

Summary

The PFS serves as the primary reimbursement framework for healthcare professionals enrolled in Medicare. Through the CMS PFS lookup tool, physicians and CBOs can review the most current CMS reimbursement rates by CPT code for Medicare and confirm allowable amounts for specific services.

Because CMS updates the PFS every year, routinely checking for revisions helps ensure accurate billing, regulatory compliance, and appropriate patient cost estimates.
