For CY 2026, Medicare no longer applies a single Physician Fee Schedule conversion factor to every claim. CMS finalized two separate conversion factors: $33.5675 for clinicians who hold Qualifying APM Participant (QP) status and $33.4009 for everyone else (non-QP). Both figures start from the CY 2025 conversion factor of $32.3465 and diverge only because of a statutory update that treats QPs and non-QPs differently.
QPP, QP, and APM Are Not the Same Thing
Before comparing dollar amounts, it’s worth separating three terms that get blended together in casual usage:
| Term | What it actually means |
|---|---|
| QPP (Quality Payment Program) | The overarching CMS framework created by MACRA, which includes both MIPS and Advanced Alternative Payment Models (APMs) |
| APM (Alternative Payment Model) | A specific payment arrangement (e.g., certain ACO or bundled-payment models) that a clinician or group may participate in |
| QP (Qualifying APM Participant) | The status a clinician earns by meeting CMS-defined payment or patient-count thresholds through an Advanced APM in a given performance year |
The higher conversion factor doesn’t apply because a practice is “in the QPP” generally — every Medicare-billing clinician is technically subject to QPP. It applies specifically to clinicians who meet the QP threshold for that performance year. This is the detail most secondary sources compress into “QPP conversion factor,” which is imprecise. The more accurate label is the QP conversion factor, and RVUinUSA uses that terminology in its APM impact calculator to avoid implying that QPP enrollment alone triggers the higher rate.
Why Two Conversion Factors Exist in 2026
The split is a statutory requirement under MACRA, not a discretionary CMS policy choice, and 2026 is the first year it takes effect. The base update differs by group:
- QP conversion factor update: +0.75%
- Non-QP conversion factor update: +0.25%
On top of that statutory split, CMS layered in additional adjustments that apply to both groups roughly equally: a 2.5% statutory increase tied to recent budget legislation, an RVU budget-neutrality adjustment, and roughly a 0.49% adjustment linked to changes in work RVU values across the fee schedule. After all adjustments, the final CY 2026 figures are:
| Conversion Factor | CY 2025 Value | CY 2026 Value | Year-over-Year Change |
|---|---|---|---|
| QP (Qualifying APM Participant) | $32.3465 | $33.5675 | +3.77% |
| Non-QP | $32.3465 | $33.4009 | +3.26% |
The gap between the two — about $0.1666 per RVU — looks small in isolation, but it compounds across every RVU-based service a clinician bills in a year.
Where the Conversion Factor Fits in a Medicare Payment Calculation
The conversion factor is the last multiplier in the Medicare Physician Fee Schedule payment formula. It converts an abstract, code-specific RVU value into an actual dollar amount. The standard structure is:
Medicare Payment ≈ [(Work RVU × Work GPCI) + (PE RVU × PE GPCI) + (MP RVU × MP GPCI)] × Conversion Factor
Each RVU component reflects a different cost input tied to the CPT or HCPCS code being billed:
| RVU Component | What It Represents |
|---|---|
| Work RVU (wRVU) | Physician time, skill, effort, and judgment for the service |
| Practice Expense RVU (PE RVU) | Clinical staff, equipment, supplies, and overhead |
| Malpractice RVU (MP RVU) | Malpractice insurance cost associated with the service |
The Geographic Practice Cost Index (GPCI) adjusts each component for local cost-of-living and labor cost differences before the conversion factor is applied, so two practices billing the identical CPT code can see different payments purely because of locality — a separate variable from QP status entirely. The QP-vs-non-QP comparison should never be run alongside a locality change or CPT code change in the same scenario, because doing so mixes two unrelated payment variables and makes it impossible to isolate what actually caused the payment difference.
A Worked Example (Illustrative Only)
Assume a hypothetical adjusted total RVU of 3.00 for a given CPT code after GPCI adjustment has already been applied. This is an example value for illustration, not an official CMS RVU for any specific code.
| Scenario | Adjusted Total RVU | Conversion Factor | Estimated Payment |
|---|---|---|---|
| Non-QP | 3.00 | $33.4009 | $100.20 |
| QP | 3.00 | $33.5675 | $100.70 |
The difference here is $0.50 per service. For a solo clinician billing a handful of encounters, that’s negligible. For a multi-specialty group billing thousands of RVU-weighted services per year, the aggregate difference between QP and non-QP status can run into tens of thousands of dollars — which is exactly why revenue cycle and contract-modeling teams use a side-by-side comparison rather than a single blended estimate. You can run this same comparison against your own volume assumptions using RVUinUSA’s APM conversion factor calculator.
QP Status Is Determined Outside the Calculator
No calculator — including RVUinUSA’s — can determine whether a given clinician or group actually qualifies as a QP for a performance year. That determination depends on:
- Participation in a CMS-designated Advanced APM
- Meeting the payment amount or patient count thresholds CMS sets for QP status that year
- CMS’s own Advanced APM participation lookup, which confirms status at the individual or entity level
Because eligibility can’t be inferred from RVU or CPT data alone, the practical default is to treat the non-QP conversion factor as the conservative planning baseline. If QP status is confirmed, that scenario should be clearly labeled as conditional in any exported comparison, contract model, or forecast — not presented as the default assumption for a clinician whose status hasn’t been verified. RVUinUSA’s QP vs. non-QP comparison guide walks through how to confirm status before modeling it.
What Stays Fixed When Comparing QP and Non-QP
A clean QP-vs-non-QP comparison holds every other payment variable constant and changes only the conversion factor:
- CPT or HCPCS code
- Site of service
- Locality and GPCI values
- Work RVU, PE RVU, and MP RVU inputs
- Service volume
If any of these shift between the two scenarios, the resulting dollar difference no longer isolates the effect of QP status — it becomes a mix of geography, coding, or volume changes that will produce misleading comparisons in a contract negotiation or budget forecast.
Don’t Confuse This With wRVU-Based Physician Compensation
The QP and non-QP conversion factors apply strictly to Medicare Physician Fee Schedule reimbursement — the amount CMS actually pays for a claim. They have no direct bearing on wRVU-based physician compensation, which is an internal metric many employers use to calculate salary or productivity bonuses (commonly expressed as dollars per wRVU, a rate the employer sets independently of Medicare’s conversion factor). A physician’s compensation rate per wRVU is negotiated or benchmarked against national compensation surveys, not derived from the Medicare conversion factor, even though both use “RVU” terminology. If you’re modeling compensation rather than Medicare reimbursement, RVUinUSA’s wRVU compensation calculator is the more relevant tool, since it uses work RVU volume and a compensation rate rather than the full Medicare payment formula.
Practical Notes for Anesthesia and Other Exceptions
Anesthesia services are priced using a separate anesthesia conversion factor structure, which also splits by QP status in 2026 but starts from a different base value and includes additional adjustments unique to anesthesia billing. If you’re modeling anesthesia CPT codes specifically, don’t apply the standard $33.5675 / $33.4009 figures — use the anesthesia-specific conversion factors instead, since mixing the two will produce incorrect payment estimates.
Bottom Line for Modeling 2026 Payments
When you’re running a QP-vs-non-QP comparison for policy analysis, contract negotiation, or revenue forecasting, treat the conversion factor as the single variable under test. Confirm QP status through CMS records rather than assuming it, default to the non-QP rate of $33.4009 when status is unverified, and keep RVU components, GPCI, and CPT code fixed across both scenarios. That discipline is what separates a useful sensitivity analysis from a number that looks precise but mixes unrelated payment variables together.
