The 2027 Payment Squeeze: How Practice Expense and Same-Day E/M Changes Could Affect Specialty Revenue
Specialty practices may enter 2027 with more than a routine Medicare fee schedule update. They may face a payment squeeze created by several changes arriving at the same time.
CMS proposes new Medicare Physician Fee Schedule conversion factors, a revised practice expense methodology, and a payment reduction when certain evaluation and management visits occur on the same day as global procedures. Each proposal deserves attention on its own. Together, they could change the financial performance of common specialty workflows.
The risk will not be equal across every specialty, provider, location, or procedure. That is precisely why broad summaries are not enough.
If you lead a specialty practice, revenue cycle management organization, or finance team, now is the time to model your actual CPT code mix, same-day service patterns, sites of care, and Medicare volume. The question is not simply whether Medicare payment will decrease. The better question is: Where could your organization feel the decrease first?
1. Start With the Broader CY 2027 Medicare Payment Picture
CMS issued the proposed rule for the CY 2027 Medicare Physician Fee Schedule on July 14, 2026. These policies remain proposals and may change before CMS publishes the final rule. If finalized, most changes would take effect on January 1, 2027. The public comment period closes September 14, 2026.
The proposed conversion factors create the first layer of financial pressure.
CMS proposes a $33.17 conversion factor for qualifying Advanced Alternative Payment Model participants, a projected 1.19 percent decrease from the current $33.57 conversion factor. For clinicians who are not qualifying APM participants, CMS proposes a $32.84 conversion factor, a projected 1.68 percent decrease from the current $33.40 conversion factor.
These decreases partly reflect the expiration of the temporary 2.5 percent payment increase that applies in 2026.
Those percentages may look manageable on an executive summary. They become less comfortable when combined with:
Changes to individual relative value units
Revisions to practice expense calculations
Same-day E/M payment reductions
Shifts in procedure volume
Changes in site of service
Rising staffing, supply, technology, and occupancy costs
A practice can therefore experience more exposure than the conversion-factor change suggests. A modest national-level percentage can become a much larger operational problem when it hits a heavily used service line.
2. What Is an RVU in Healthcare?
To understand the proposed practice expense change, we first need to answer a basic but important question: What is an RVU in healthcare?
A relative value unit, or RVU, represents the resources associated with furnishing a Medicare service. Medicare generally calculates payment using three RVU components:
Work RVU: The clinician’s time, skill, effort, and judgment.
Practice expense RVU: The direct and indirect costs of operating the practice and furnishing the service.
Malpractice RVU: The professional liability expense associated with the service.
CMS then applies geographic adjustments and the applicable conversion factor to produce the Medicare payment amount.
This helps explain how RVUs are calculated, but it also reveals why practices cannot focus only on the work relative value unit. A clinician’s work RVU may remain stable while a change to the practice expense RVU affects the total payment for the service.
For specialty organizations with equipment, clinical staff, procedure rooms, supplies, scheduling teams, billing personnel, and other operational costs, practice expense is not a minor technical detail. It is part of the financial structure supporting care delivery.
3. What CMS Proposes to Change About Practice Expense
CMS has historically used specialty-level survey data to help calculate practice expense under the Physician Fee Schedule. Some of the specialty-specific practice expense-per-hour data currently influencing the methodology originated in 2007 or earlier.
CMS says this older information has become difficult to update and may produce results that are unpredictable, difficult to explain, or disconnected from newer code-level cost data.
For CY 2027, CMS proposes beginning to move away from the part of the methodology tied to the indirect practice cost index, or IPCI. The IPCI helps align overall practice expense RVUs for a specialty with historical specialty survey information.
CMS proposes a two-year transition:
In the first year, only half of the measured IPCI variation would apply.
In the second year, CMS would remove the IPCI from the calculation.
CMS also proposes a practice expense stabilizer intended to reduce sudden year-to-year volatility. Under the proposal, the practice expense RVU for many existing codes generally would not increase or decrease by more than 5 percent in one year because of the revised methodology. Certain new, revised, revalued, or newly nationally priced codes would not receive the same protection. Other statutory adjustments could also cause the final change for a code to exceed the stabilizer.
The proposal does not mean every specialty practice will lose 5 percent on every service. It also does not guarantee that every affected code will remain within a 5 percent total payment change.
It means practices need code-level analysis.
4. Why the Practice Expense Proposal Could Affect Specialties Differently
The proposed methodology would continue to consider work RVUs, direct practice expense inputs, and specialty-specific indirect allocators. However, it would reduce the influence of historical specialty-level survey data on the final calculation.
That shift could redistribute practice expense value across services.
The potential effect depends on factors such as:
The practice’s most frequently billed CPT codes
Whether services include costly clinical labor, equipment, or supplies
The mix of cognitive and procedural services
Whether services occur in an office or facility
Whether a code has recently been revised or revalued
The specialty mix of clinicians furnishing the service
Medicare’s budget-neutral rate-setting requirements
An office-based specialty practice and a hospital-employed specialty group may bill similar clinical services but carry different practice costs and receive different Physician Fee Schedule amounts because of the site of service.
CMS generally includes the full range of practice resources in the nonfacility rate for services furnished in a physician’s office. In a facility, such as a hospital outpatient department or ambulatory surgical center, the professional payment reflects only the resources typically incurred by the practitioner because the facility may receive separate payment for its costs.
This is why CFOs should avoid applying a single estimated Medicare percentage across the entire organization. The calculation must account for the code, provider, location, payer, and service combination.
5. The Same-Day E/M Proposal Creates a More Visible Revenue Risk
CMS also proposes to reduce payment when a separately identifiable office or outpatient E/M visit is furnished by the same physician, or another physician in the same practice, on the same day as a procedure with a 0-day, 10-day, or 90-day global period.
If finalized:
The most expensive service, whether the procedure or E/M visit, would receive 100 percent payment.
The other same-day surgical procedures or E/M visits would receive 50 percent payment.
CMS states that the proposed reduction would address what the agency views as overlapping resources when the same practice provides an E/M visit and global procedure on the same day. CMS considered a similar policy in 2019 but did not finalize it then.
This proposal could affect specialties that frequently evaluate a patient and perform a procedure during the same encounter. Depending on the practice’s service mix, that may include:
Dermatology
Cardiology
Orthopedics
Pain management
Ophthalmology
Gastroenterology
Otolaryngology
Urology
General surgery
Other office-based procedural specialties
The proposal does not automatically make the E/M service improper. A separately identifiable E/M visit may still be clinically appropriate and correctly documented. The proposed policy addresses payment, not merely whether the service can be reported.
That distinction matters.
A practice could have compliant documentation, correct modifier use, and a medically necessary E/M service, yet still receive reduced payment if the proposal becomes final.
6. How Specialty Practices Should Measure Same-Day Exposure
Your analysis should begin with claims data, not assumptions.
Pull at least 12 months of Medicare claims and identify encounters containing:
An office or outpatient E/M code
A procedure with a 0-day, 10-day, or 90-day global period
The same patient and date of service
The same physician or another physician in the same group practice
Modifier 25 or other relevant claim indicators
The allowed amount for each service
Next, determine which service was more expensive. Under the proposal, the most expensive service would remain at 100 percent while the other applicable services would be paid at 50 percent.
A basic exposure estimate can use this calculation:
Potential same-day exposure = 50 percent of the allowed amount for each lower-priced affected service
The estimate should then be grouped by:
Specialty
Physician
CPT code
Procedure category
Location
Month
Medicare revenue
Frequency of same-day combinations
This will show whether the exposure is spread across the practice or concentrated among a few high-volume codes and clinicians.
Do not use the results to pressure clinicians into separating medically appropriate care solely to protect revenue. That could create patient access problems, additional travel, delayed treatment, and compliance concerns.
Instead, use the findings to improve forecasting, documentation, scheduling guidance, patient communication, and service-line planning.
7. RCM Leaders Need to Look Beyond the Denial Dashboard
The proposed same-day reduction creates an important challenge for revenue cycle management teams: a correctly processed claim can still produce less revenue.
A denial dashboard may show no failure. The claim may be accepted, adjudicated, and paid exactly as CMS policy requires. The financial damage may appear only as a lower allowed amount.
RCM teams should therefore prepare to distinguish among:
A denied same-day E/M service
A modifier or documentation problem
A contractual adjustment
A multiple-procedure payment reduction
A payment reduction caused by the proposed CY 2027 policy
A lower rate caused by revised RVUs or the conversion factor
Without this distinction, a practice may mistake policy-driven underperformance for a billing problem. It may also overlook a true payment error because staff assumes every decrease came from the new rule.
This is where RCM partnerships need a stronger regulatory layer. Claims processing tells you what happened to the claim. Regulatory analysis helps explain why it happened and what it means for the client’s financial plan.
8. Build a CY 2027 Specialty Payment Impact Model Now
Waiting for the final rule may feel cautious. It can also leave too little time to analyze codes, revise budgets, update systems, and educate teams before January 1.
We recommend building three scenarios:
Scenario 1: Current Policy Baseline
Use current RVUs, conversion factors, same-day payment rules, volumes, and sites of service.
Scenario 2: Proposed CY 2027 Policy
Apply the proposed conversion factor, available proposed RVUs, practice expense changes, and same-day E/M reduction.
Scenario 3: Operational Stress Test
Use the proposed policy assumptions, then add realistic operational pressures such as:
Higher labor costs
Supply inflation
Changes in Medicare volume
Provider vacancies
Shifts between office and facility settings
Increased claim rework
Changes in procedure demand
The model should produce more than one projected revenue number. It should identify:
Codes with the greatest dollar exposure
Services with the greatest percentage change
Providers with high same-day service volume
Locations with concentrated Medicare risk
Monthly cash-flow implications
Contract and staffing decisions that may require review
Your RCM partner should contribute clean claims data and payment intelligence. Your finance team should translate the findings into budgets and margin forecasts. Clinical and operational leaders should evaluate whether current workflows remain appropriate for patients.
9. Questions Every Specialty CFO Should Ask
Before approving a 2027 budget, pause and ask:
Which CPT codes generate most of our Medicare revenue?
Which codes could experience practice expense RVU changes?
How often do we bill E/M visits with global procedures on the same day?
Which service receives the lower allowed amount in those combinations?
How does exposure vary by specialty, physician, and location?
Are we modeling office and facility services separately?
Can our billing system identify a policy-based reduction instead of classifying it as a generic adjustment?
Does our RCM partner provide regulatory forecasting or only retrospective claims reporting?
Which assumptions must be updated after CMS publishes the final rule?
Who owns the final financial validation before January 1, 2027?
If your organization cannot answer these questions, the payment risk is not yet under control.
Prepare for the Proposal Without Treating It as Final
CMS proposes significant changes to the way Medicare could calculate practice expense and pay for certain same-day E/M and global-procedure combinations in 2027. The final policy may differ, but the potential exposure is concrete enough to measure now.
Specialty practices should not rely on a national specialty percentage or a general reimbursement forecast. Your true exposure sits inside your CPT mix, care settings, same-day service patterns, Medicare volume, and operating costs.
