The CY 2026 Medicare Physician Fee Schedule (MPFS) final rule, CMS-1832-F, took effect January 1, 2026, and for the first time in Medicare’s history it uses two separate conversion factors instead of one: $33.5675 for clinicians who qualify as participants in an Advanced Alternative Payment Model (QPs), and $33.4009 for everyone else (non-QPs). Both numbers are up from the CY 2025 conversion factor of $32.35, but the increase is layered with an offsetting cut that most practices need to understand before assuming their Medicare revenue is simply going up.
The Two Conversion Factors, Side by Side
| Conversion Factor Type | CY 2025 | CY 2026 | Change |
|---|---|---|---|
| Qualifying APM Participant (QP) | $32.35 | $33.5675 | +3.77% |
| Non-Qualifying (all other physicians) | $32.35 | $33.4009 | +3.26% |
This split exists because of a statutory requirement that took effect for the first time in CY 2026: physicians who meet participation thresholds in an Advanced APM get a slightly higher baseline update than those who don’t. If you’re reconciling estimated Medicare payment for a client or your own practice using a Medicare reimbursement calculator, the first input that matters is whether the billing provider is a QP — using the wrong conversion factor will throw off every downstream payment estimate.
What Actually Built the 2026 Conversion Factor
The final CF isn’t one clean annual “raise.” CMS combined four separate statutory and regulatory components:
| Component | QP Impact | Non-QP Impact |
|---|---|---|
| One-year statutory increase (One Big Beautiful Bill Act) | +2.50% | +2.50% |
| Permanent MACRA baseline update | +0.75% | +0.25% |
| Budget-neutrality adjustment | +0.49% | +0.49% |
| Net CF increase | +3.77% | +3.26% |
The +0.49% budget-neutrality adjustment is where things get more complicated, because it’s the netted result of code-level revaluations and a new, separately finalized cut called the efficiency adjustment — described below. Budget neutrality is a zero-sum mechanic under the MPFS: when CMS revalues some services upward, the conversion factor across all services must shift downward (or vice versa) to keep total program spending flat, as required by statute.
The Efficiency Adjustment: A New Downward Pressure on Work RVUs
This is the most consequential — and least publicized — change in the CY 2026 rule for anyone tracking work RVU (wRVU) data. CMS finalized a -2.5% efficiency adjustment applied directly to the work RVUs (and the corresponding intraservice physician time) of non-time-based services, on the theory that many procedures have become faster to perform than the original RUC survey data assumed.
A few things matter here for accurate interpretation:
- The adjustment applies to roughly 7,000 HCPCS/CPT codes and touches an estimated 91% of physician services billed under the MPFS.
- It is exempt for time-based codes: evaluation and management (E/M) visits, care management services, behavioral health services, codes on the Medicare telehealth list, and maternity codes with a global period of “MMM”.
- It reduces the work RVU value assigned to the code in the MPFS — not the practice expense or malpractice RVU components.
This is a case where the distinction between work RVU and total RVU genuinely changes the payment math. Work RVU accounts for physician effort, skill, and time; total RVU adds practice expense (PE) RVU and malpractice (MP) RVU on top. Because the efficiency adjustment only touches the work component, its effect on final Medicare payment for a given code depends on how large the work RVU share was relative to PE and MP RVUs for that specific service.
Practice Expense RVU Changes: Facility vs. Non-Facility
CMS also finalized a structural change to how it allocates indirect practice costs between facility settings (hospital outpatient departments, ambulatory surgical centers) and non-facility settings (physician offices). Historically, the PE methodology assumed physicians maintained a separate office practice even when performing procedures in a hospital — an assumption CMS says no longer reflects how much of the physician workforce is now hospital-employed.
The practical result:
| Setting | 2026 Practice Expense Direction |
|---|---|
| Office-based (non-facility) | Indirect cost allocation increased — net gain for many office-heavy specialties (family medicine, rheumatology, allergy/immunology) |
| Facility-based (hospital, ASC) | Indirect cost allocation reduced — CMS and AMA estimate an average 7% overall reduction in facility-setting PE RVUs |
Specialty-level impact estimates cited by the AMA’s analysis of the final rule include double-digit cuts for some specialties once the efficiency adjustment and PE changes are combined — for example, over half of internists and ophthalmologists, and roughly a third of oncologists and OB-GYNs, are projected to see reductions of 5% or more depending on their site-of-service mix. These are aggregate specialty-level estimates from AMA modeling, not fixed rates for any individual CPT code, so practice-specific impact depends heavily on each group’s actual case mix and setting of service.
CMS also finalized updates to the geographic practice cost indices (GPCIs) and malpractice RVUs for 2026, as required by statute every three years for GPCIs. If you’re comparing payment for the same CPT code across two localities using a GPCI calculator, make sure the dataset reflects 2026 GPCI values — locality-specific factors shift with each triennial update, and applying an outdated GPCI file to 2026 RVU data will produce an inaccurate payment estimate.
How the Pieces Combine Into a Medicare Payment
None of these RVU or conversion factor changes translate into payment on their own — they combine through the standard MPFS payment formula:
Medicare Payment = [(Work RVU × Work GPCI) + (PE RVU × PE GPCI) + (MP RVU × MP GPCI)] × Conversion Factor
Here is an illustrative walkthrough (using rounded, hypothetical RVU values — not an actual CPT code’s published data) to show how the mechanics interact:
- Assume a service has a work RVU of 2.00, PE RVU of 1.50, and MP RVU of 0.15 (illustrative values only).
- Apply locality-specific GPCIs — for example, Work GPCI 1.00, PE GPCI 1.05, MP GPCI 0.90 (illustrative).
- Geographically adjusted total: (2.00 × 1.00) + (1.50 × 1.05) + (0.15 × 0.90) = 2.00 + 1.575 + 0.135 = 3.71.
- Multiply by the applicable 2026 conversion factor. For a non-QP physician: 3.71 × $33.4009 ≈ $123.92 (illustrative estimate, not an official Medicare rate).
The key takeaway is structural, not numerical: a code’s published work RVU for 2026 already reflects the -2.5% efficiency adjustment if it applies, and the published PE RVU already reflects the facility/non-facility reallocation. You don’t apply those cuts a second time — they’re baked into the RVU values CMS publishes in the annual PFS Relative Value File. A CPT RVU calculator that pulls current-year RVU data handles this automatically, but manual calculations built on 2025 RVU files will misstate 2026 payment.
Where wRVU-Based Compensation Diverges From Medicare Payment
This is a common point of confusion for practice managers and compensation analysts, and the 2026 rule makes it more visible than usual. Work RVU, as published in the MPFS relative value file, is a Medicare-specific measure used to calculate Medicare payment. Many hospitals and medical groups separately use work RVU counts — often the same or a similar dataset — as the productivity metric in wRVU-based physician compensation plans, where a physician is paid a negotiated dollar rate per wRVU generated, regardless of payer mix.
These are related but functionally separate systems:
| Medicare Payment RVU | wRVU-Based Compensation | |
|---|---|---|
| Purpose | Determines Medicare reimbursement rate | Determines physician’s internal productivity pay |
| Formula | Total RVU × GPCI × Conversion Factor | wRVU × employer’s negotiated $/wRVU rate |
| Affected by CMS’s 2026 efficiency adjustment | Yes, directly (work RVU values are revised in the fee schedule) | Only if the employer’s compensation plan adopts the updated CMS relative value file |
| Affected by GPCI | Yes | No — compensation plans typically don’t apply geographic adjusters |
| Paid per payer | Only reflects Medicare, not commercial payers | Reflects total productivity across all payers combined |
If a hospital’s compensation plan is contractually tied to the CMS relative value file, a physician doing a high volume of non-time-based procedures could see their wRVU output — and therefore compensation — decline in 2026 purely because CMS lowered the work RVU value of those codes, even though the physician’s actual clinical effort hasn’t changed. Practice managers and compensation analysts should confirm which year’s RVU file their compensation plan references before assuming 2026 productivity numbers are comparable to 2025.
Other Notable 2026 Policy Changes
A handful of additional finalized changes affect billing and coding workflows beyond the RVU and conversion factor math:
- Telehealth: Frequency limits were permanently removed for subsequent inpatient visits, subsequent nursing facility visits, and critical care consultations; a permanent definition of “direct supervision” now allows real-time audio-video (not audio-only) virtual supervision for most services requiring it.
- Skin substitutes: Products are now paid as incident-to supplies rather than under the ASP-based biological payment methodology, with a finalized single payment rate of approximately $127.28 across FDA regulatory categories for 2026.
- Behavioral health integration: Three new G-codes were finalized as optional add-ons to Advanced Primary Care Management (APCM) billing to support Behavioral Health Integration and Collaborative Care Model services.
- Digital mental health treatment (DMHT): Payment policy was expanded to cover devices used in ADHD treatment, in addition to existing behavioral health uses.
None of these items change the core RVU-to-payment formula, but they do affect which HCPCS/CPT codes a practice should be billing and how claims should be structured for 2026 dates of service.
Practical Takeaway for Coders and Analysts
When comparing 2025 and 2026 payment for the same CPT code, don’t rely on the conversion factor increase alone. The net effect on any given code depends on three moving parts working in the same calculation: whether the code’s work RVU was reduced by the efficiency adjustment, whether its PE RVU shifted because of the facility/non-facility reallocation, and which of the two 2026 conversion factors applies to the billing provider. Pulling current-year RVU data into a wRVU calculator or RVU comparison tool is the most reliable way to see the combined effect for a specific code rather than estimating from the headline conversion factor percentage alone.
