What Is Changing in the 2027 Medicare Physician Fee Schedule?

As of September 2026, CMS has proposed reducing the Medicare Physician Fee Schedule conversion factor for calendar year 2027. The 2.5% temporary statutory increase that Congress provided for 2026 expires on December 31, 2026, resulting in a net payment reduction of approximately 2% for most physician services starting January 1, 2027. The comment period on the proposed rule (CMS-1848-P) closed on September 14, 2026, and CMS is expected to finalize the rule this fall.

  • Conversion factor drop: The proposed CY 2027 conversion factor falls from $33.5675 (qualifying APM participants) to $33.1693, a reduction driven by the expiration of the temporary congressional increase.
  • Timeline: CMS released the proposed rule on July 14, 2026. The comment period closed September 14, 2026. The final rule is expected in November or December 2026, with changes taking effect January 1, 2027.
  • Commercial contract impact: Practices that base commercial payer rates on a percentage of Medicare will see those rates drop automatically unless contracts are renegotiated before the new conversion factor takes effect.

What CMS Proposed in the CY 2027 Rule

On July 14, 2026, CMS released the CY 2027 Medicare Physician Fee Schedule proposed rule (CMS-1848-P). The rule covers payment rates and policy changes for Medicare Part B services effective January 1, 2027. The proposed conversion factor for qualifying alternative payment model (APM) participants drops from $33.5675 to $33.1693. For non-qualifying APM participants, the conversion factor moves from $33.2036 to $32.8055. Both figures reflect statutory updates of +0.75% (qualifying APM) and +0.25% (non-qualifying APM), plus an estimated +0.53% budget neutrality adjustment, according to the CMS fact sheet published July 15, 2026.

The catch is the expiration of Public Law 119-21, which provided a one-time 2.5% conversion factor increase for CY 2026. That increase sunsets on December 31, 2026, and current law does not extend it. The result is a net reduction in physician payments of roughly 2% compared to what practices receive today. CMS has acknowledged that Medicare physician payment updates continue to lag behind increases in the Medicare Economic Index (MEI), which measures practice cost inflation. In our experience helping providers negotiate payer contracts, this gap between actual costs and Medicare reimbursement has been widening steadily, and each fee schedule cycle makes the conversation with commercial payers more urgent.

Beyond the conversion factor, CMS included several Requests for Information (RFIs) signaling potential longer-term changes to physician payment. One RFI asks for stakeholder feedback on the CPT coding and valuation process itself, including the role of the AMA’s Relative Value Scale Update Committee (RUC) in setting relative value units. Another explores expanded primary care payment models. These RFIs do not change anything for 2027, but they suggest CMS is laying groundwork for more structural reforms.

Who Does the 2027 Fee Schedule Cut Affect?

The payment reduction touches every provider and practice that bills Medicare Part B services under the Physician Fee Schedule. That includes physicians, nurse practitioners, physician assistants, clinical psychologists, social workers, physical therapists, and any other clinician who submits claims under PFS codes. Group practices with multiple providers feel the impact across every rendering provider on their roster.

Specialty mix matters. Practices with a heavy share of evaluation and management (E/M) codes may see slightly different impacts than procedure-heavy specialties because CMS periodically adjusts relative value units (RVUs) for specific code families. However, the conversion factor reduction applies uniformly to the final payment calculation, so no specialty escapes the baseline cut.

The downstream effect extends to commercial payer contracts. Many commercial contracts set reimbursement as a percentage of Medicare, such as 120% or 140% of the current Medicare fee schedule. When Medicare’s conversion factor drops, those contract rates drop with it unless the contract language specifies a fixed conversion factor or includes a floor. Providers often come to us after discovering their commercial reimbursement decreased without any notification because their contract was pegged to Medicare rates. Our payer contract negotiation services are built to catch exactly this kind of silent rate erosion before it compounds.

Why the Temporary Payment Increase Expiration Matters More Than Usual

Congress has a pattern of providing short-term fixes to prevent steep physician payment cuts under the fee schedule. In 2024, a 2.93% increase was signed into law. For 2025, a 2.83% increase was provided. For 2026, Public Law 119-21 delivered a 2.5% increase. Each of these was temporary, and each expired at the end of the calendar year. The 2027 proposed rule is built on the assumption that no new legislation extends the increase.

What makes 2027 different is the cumulative effect. Each year’s temporary fix patches the current year but does not raise the permanent baseline. The permanent conversion factor has been essentially flat since the sustainable growth rate (SGR) was replaced in 2015 by the Medicare Access and CHIP Reauthorization Act (MACRA). Meanwhile, practice costs measured by the MEI have climbed. The gap between what it costs to run a practice and what Medicare pays for services continues to widen. For a practice with 40% Medicare payer mix, a 2% fee schedule reduction translates to roughly 0.8% of total revenue. That may sound small, but stacked on top of rising staff costs, higher malpractice premiums, and drug pricing volatility, it compounds into real financial pressure.

The practical question for practice managers is not whether Congress will pass another temporary fix. It might. The question is whether your revenue strategy should depend on that possibility. In our experience working with practices on payer contract negotiations, the ones that plan for the worst-case scenario and renegotiate proactively are the ones that protect their margins regardless of what happens in Washington.

How Does the Medicare Fee Schedule Payment Cut Affect Commercial Payer Contracts?

Commercial payer contracts reference Medicare rates in several ways, and each creates a different exposure to the 2027 reduction. Understanding your contract language is the first step in protecting your reimbursement.

Contract LanguageHow It WorksExposure to 2027 Cut
% of current MedicareRate adjusts automatically when CMS updates the conversion factorHigh. Rates drop January 1 with no action required by the payer.
% of a fixed (named) Medicare yearRate is locked to a specific year’s fee schedule (e.g., 130% of CY 2025 Medicare)Low for now. Rate stays flat until the contract is renegotiated or renewed.
Custom fee scheduleRates are set per procedure code and do not reference MedicareNone directly, but renewal negotiations often reset to a Medicare benchmark.
Hybrid (base + escalator)Rate starts at a Medicare percentage and increases annually by a fixed percentage or CPI adjustmentMedium. The escalator may partially offset the cut, but the base resets if tied to current Medicare.

The most vulnerable practices are those with contracts pegged to “current Medicare” without a floor clause. Across the contracts we review at Contracting Providers, this is the most common structure, and it is also the one that requires the most immediate attention heading into 2027. If you are unsure how your contracts reference Medicare, our payer contract management services can help you identify the exposure.

If your commercial contracts reference Medicare rates, now is the time to review them before the 2027 conversion factor takes effect. Our team reviews payer contracts and identifies where your reimbursement is at risk.

What Should Providers Do Before January 2027?

Waiting for the final rule to act is one of the most common and costly mistakes we see. Payer contract negotiations take 3 to 6 months from initial outreach to executed amendment. If you start in January 2027, your renegotiated rates will not take effect until mid-year at the earliest. Starting now gives you the best chance of locking in improved rates before the cut hits. Here is what to prioritize:

  1. Pull and review every commercial contract that references Medicare rates. Check whether the language says “current Medicare,” “CY [year] Medicare,” or a custom fee schedule. Flag any contract tied to current Medicare with no floor clause.
  2. Run a fee schedule comparison. Compare your top 20 CPT codes by volume across each payer against both the CY 2026 and proposed CY 2027 Medicare rates. Quantify the dollar impact per code and total annual exposure.
  3. Identify contracts approaching renewal. If a contract renews in Q4 2026 or Q1 2027, the renewal window is your leverage point. Request rate increases that offset the Medicare reduction before signing.
  4. Request a rate increase on underperforming contracts now. You do not need to wait for renewal. Most payer contracts allow either party to request a rate review. Build a data-backed case using your volume, clean claims rate, and local market benchmarks.
  5. Check your Medicare enrollment status. Practices with pending revalidations or outdated PECOS records risk claim denials on top of the rate cut. Confirm that every provider on your roster has an active, current enrollment with the correct practice locations and reassignment records.
  6. Document everything for your credentialing files. Payers increasingly cross-reference enrollment records with contract data. An enrollment gap or a lapsed CAQH attestation can delay or derail a contract amendment.

Common Mistakes Practices Make During Fee Schedule Changes

Every year when CMS releases the proposed rule, the same patterns repeat. The first mistake is assuming Congress will fix it. Practices tell themselves the cut will not happen because Congress has intervened before. While that is true historically, building a revenue strategy around a legislative assumption is not a plan. It is a gamble. If Congress does pass another temporary increase, your renegotiated commercial rates simply perform better than expected. If Congress does not act, you are protected.

The second mistake is reviewing only the conversion factor without checking RVU changes. CMS adjusts relative value units for specific procedure codes every year. A code your practice bills heavily could see its RVU reduced independently of the conversion factor, compounding the payment impact. The proposed rule addenda, available on the CMS website, list every code-level change.

The third mistake is treating contract renegotiation as a one-time event. One question we hear constantly from practice managers is whether they should wait for the final rule before opening negotiations. The answer is no. Start the conversation now using the proposed conversion factor. If the final rule adjusts it slightly, you can update the numbers. The time lost waiting for finalization is time you cannot recover. Payer contracting teams move slowly, and the practices that get in line first get the most attention.

The fourth mistake is neglecting the credentialing side. A payer will not renegotiate rates with a provider whose enrollment records are incomplete, whose CAQH profile has lapsed, or whose credentialing file shows expired documents. Clean credentials are a prerequisite to contract negotiations, not a separate project.

In-House Review vs. Professional Contract Analysis

Some practices handle contract review internally, and for a solo provider with two or three payer contracts, that can work. The challenge scales with the number of providers, payers, and procedure codes involved. A 5-provider group with contracts across 8 commercial payers and Medicare has 40 or more fee schedules to track. Each payer structures its contract differently, uses different benchmarks, and has different escalation clauses, termination windows, and amendment processes.

Across the practices we work with, the most common finding during a contract review is a hidden clause that suppresses reimbursement without the practice realizing it. Escalation clauses that cap annual increases at 1% while costs rise 3% to 4%. Bundling edits written into the contract that go beyond standard NCCI rules. Silent auto-renewal terms that lock in the current rate for another 12 to 24 months if the practice misses the opt-out window. These are not theoretical risks. An ENT practice in Texas we worked with uncovered an escalation clause that had gone unnoticed for years, and the practice has since requested reprocessing of hundreds of claims based on that discovery.

Professional contract review pays for itself when it identifies even one clause that suppresses reimbursement. The cost of not reviewing is invisible until you quantify it, and by then the revenue has already been lost.

Frequently Asked Questions

When does the 2027 Medicare Physician Fee Schedule take effect?

The proposed changes take effect January 1, 2027, assuming CMS finalizes the rule as proposed. CMS typically releases the final rule in November or December. Practices should plan for the proposed rates and adjust if the final rule differs.

How much will Medicare physician payments decrease in 2027?

The net reduction is approximately 2% compared to 2026 rates. This reflects the expiration of the 2.5% temporary increase Congress provided for 2026, partially offset by small statutory updates of +0.75% for qualifying APM participants and +0.25% for all others, plus an estimated +0.53% budget neutrality adjustment.

Will Congress pass another temporary fix to prevent the payment cut?

As of September 2026, no legislation extending the 2.5% increase has been introduced. Congress has provided temporary fixes in prior years, but there is no guarantee it will act for 2027. Practices should not build their financial plans around a potential legislative intervention.

Do commercial payer rates automatically drop when Medicare rates decrease?

It depends on the contract language. Contracts that set reimbursement as a percentage of “current Medicare” will adjust automatically when the new conversion factor takes effect. Contracts tied to a fixed Medicare year or a custom fee schedule are not directly affected until renewal.

How long does it take to renegotiate a payer contract?

From initial outreach to executed amendment, the process typically takes 3 to 6 months. Some payers move faster, but many require multiple rounds of review and internal approval. Starting negotiations in September or October 2026 gives the best chance of securing updated rates before January 2027.

What is the Medicare conversion factor for 2027?

The proposed conversion factor for CY 2027 is $33.1693 for qualifying APM participants and $32.8055 for non-qualifying APM participants. These figures are proposed and may change slightly in the final rule expected later in 2026.

Next Steps

Review your payer contracts now to identify which ones reference current Medicare rates and are exposed to the 2027 reduction. Confirm your PECOS enrollment records and CAQH credentialing files are current so nothing delays a contract amendment.
