The facility or non-facility designation on a CPT code determines which practice expense (PE) RVU value CMS uses to price that service — not the physician work involved. The distinction is triggered by the place of service (POS) code submitted on the claim, and it can change the Medicare payment estimate substantially even though the physician did the same amount of clinical work.
What Facility and Non-Facility Actually Mean
Under the Medicare Physician Fee Schedule (MPFS), every CPT/HCPCS code with a professional component carries two possible PE RVU values:
- Non-facility PE RVU: applies when the service is performed in a setting like a physician’s own office, where the practice pays for staff time, supplies, equipment, and overhead.
- Facility PE RVU: applies when the service is performed in a hospital, ambulatory surgical center, skilled nursing facility, or similar setting, where the facility — not the physician’s practice — bears most of that overhead cost.
CMS does not let a practice choose the setting arbitrarily. The POS code on the claim (for example, office vs. outpatient hospital) tells the Medicare Administrative Contractor which PE RVU column to use when calculating the payment amount. This is why the same CPT code can show two different “RVU totals” depending on where it was performed — the code itself hasn’t changed, but the resource assumptions behind it have.
Work RVU Stays Constant — That’s the Key Point
For the vast majority of CPT codes, the work RVU (the component reflecting physician time, skill, and mental effort) is identical whether the code is billed with a facility or non-facility POS. What moves is the PE RVU, and in most cases the malpractice (MP) RVU stays essentially flat as well.
| RVU Component | Changes by Setting? | What It Represents |
|---|---|---|
| Work RVU | No (for most codes) | Physician time, skill, judgment, and stress |
| Practice Expense RVU | Yes | Overhead: staff, supplies, equipment, clinic space |
| Malpractice RVU | Rarely | Cost of professional liability insurance |
This separation matters for two very different audiences. A coding or billing team cares about total RVU because it drives the claim payment. A compensation analyst evaluating physician productivity typically cares only about work RVU, because most wRVU-based compensation plans credit physicians on work RVU regardless of where the service was performed. Mixing these up — assuming a facility/non-facility payment swing automatically changes a physician’s paycheck — is one of the most common errors in RVU discussions.
The Medicare Payment Formula
CMS calculates the Medicare Physician Fee Schedule payment amount using this structure, applying geographic adjustment before the conversion factor:
Non-Facility Payment = [(Work RVU × Work GPCI) + (Non-Facility PE RVU × PE GPCI) + (MP RVU × MP GPCI)] × Conversion Factor
Facility Payment = [(Work RVU × Work GPCI) + (Facility PE RVU × PE GPCI) + (MP RVU × MP GPCI)] × Conversion Factor
Each component — work, PE, and malpractice — has its own Geographic Practice Cost Index (GPCI) that adjusts for regional cost differences in labor, rent, and liability insurance before the conversion factor is applied. The conversion factor (CF) is the dollar multiplier CMS sets annually to translate total geographically adjusted RVUs into a payment amount. Beginning in CY 2026, CMS finalized two separate conversion factors: $33.57 for clinicians who qualify as Advanced Alternative Payment Model participants (QPs), and $33.40 for non-qualifying physicians and practitioners — both up from the single CY 2025 conversion factor of $32.35. This split is a structural change from prior years, when a single CF applied to nearly everyone, so any comparison across years needs to specify which CF version applies.
Illustrative Calculation (Example Values Only)
Assume a hypothetical CPT code with a work RVU of 1.00, a non-facility PE RVU of 1.20, a facility PE RVU of 0.55, and an MP RVU of 0.08. Using GPCI values of 1.00 for simplicity and the CY 2026 non-QP conversion factor of $33.40:
- Non-facility total RVU = 1.00 + 1.20 + 0.08 = 2.28 → Payment ≈ 2.28 × $33.40 = $76.15
- Facility total RVU = 1.00 + 0.55 + 0.08 = 1.63 → Payment ≈ 1.63 × $33.40 = $54.44
The work RVU credited toward physician productivity is 1.00 in both scenarios — it’s the payment estimate, not the productivity credit, that drops by roughly $21.71 in this example. These figures are illustrative only; actual RVU values and GPCI factors must be pulled from the current MPFS relative value file for the specific CPT code and locality in question, which you can look up directly in a CPT RVU reference tool or run through an RVU calculator alongside a Medicare reimbursement calculator for the exact locality.
Why Non-Facility PE RVU Is Usually Higher
Non-facility PE RVU is generally higher because CMS assumes the physician’s own practice — not a hospital or ASC — is absorbing the direct cost of staff, supplies, equipment, and space for that encounter. When the same service is billed with a facility POS, CMS assumes the facility (which bills separately, often under OPPS) is covering most of that overhead, so the professional-side PE RVU drops accordingly.
This is a pricing assumption, not a profitability statement. A higher non-facility payment doesn’t automatically mean a practice makes more money on that encounter — actual margin depends on real overhead costs, payer mix, and collections rate, none of which the RVU formula captures.
One nuance worth flagging for 2026: CMS finalized a change reducing the portion of facility PE RVUs allocated to the physician-work-driven share, cutting it to half the amount allocated under the non-facility PE RVU methodology starting in CY 2026. This means the facility/non-facility payment gap for many codes may widen further under the new rule compared to CY 2025 and earlier years — a good reason not to assume last year’s facility/non-facility spread still holds.
GPCI Interacts With Whichever PE RVU You Select
The PE GPCI multiplies whichever PE RVU is in play — facility or non-facility — for a given locality. Because non-facility PE RVU is usually the larger number, the dollar impact of PE GPCI is often larger in the non-facility scenario, even if the GPCI value itself is the same.
Practical implication for locality comparisons: if you’re comparing Medicare payment for the same CPT code across two GPCI localities, hold the facility/non-facility setting constant. Comparing a non-facility payment in one locality against a facility payment in another mixes two different cost bases and produces a meaningless spread. A GPCI calculator is useful here specifically because it lets you lock the setting and vary only the locality.
Physician Compensation: Where Setting Usually Doesn’t Matter
This is the point where confusion causes real financial disputes in compensation reviews.
| Compensation Model | Sensitive to Facility/Non-Facility Setting? |
|---|---|
| Pure wRVU-based compensation | Typically no — work RVU is usually unchanged by setting |
| Total RVU-based compensation | Yes — total RVU shifts with PE RVU |
| Collections- or net-revenue-based compensation | Yes — payer payment amount changes with setting |
| Blended (base salary + wRVU incentive) | Usually no, for the wRVU-driven portion |
If a physician compensation agreement is built on work RVU — which is the most common structure in employed-physician and academic settings — a facility/non-facility payment difference generally has no direct effect on the compensation calculation, because wRVU-based compensation is a productivity metric, not a Medicare reimbursement pass-through. The formula wRVU × compensation rate = estimated physician compensation (e.g., 1.00 wRVU × an example rate of $55 per wRVU = $55, using an illustrative, non-official rate) operates independently of what Medicare actually pays for that encounter.
Where setting does matter is when the compensation formula references collections, net revenue, or total RVU explicitly. In those structures, a shift from non-facility to facility billing can lower the revenue or total RVU base the compensation formula is applied to, even though the physician’s wRVU credit for that encounter is unchanged. Before assuming a facility/non-facility payment gap affects take-home compensation, the actual contract language needs to be checked to see which financial measure — wRVU, total RVU, collections, or net revenue — is the operative variable.
Practical Steps for Using RVU Data by Setting
- Look up the specific CPT code in a reliable relative value file or CPT RVU calculator and record both the facility and non-facility PE RVU values separately — they are listed as two distinct columns, not a single number.
- Confirm which POS code applies to the actual encounter being modeled; that determines which PE RVU column CMS will use for the real claim.
- Run the payment estimate using the correct current-year GPCI values for the locality and the applicable CY 2026 conversion factor (QP or non-QP, depending on the billing provider’s participation status).
- If the goal is compensation analysis rather than payment estimation, use work RVU only, and verify against the actual compensation agreement whether total RVU or collections language changes that conclusion.
- When comparing across localities, keep the facility/non-facility setting fixed unless the site-of-service impact is the specific question being asked.
Documenting which setting was used with every reported RVU or payment figure avoids the most common source of error in facility/non-facility analysis: comparing numbers that were never meant to be compared side by side.
