When You Work With an NP or PA: Who Gets the wRVU Credit?

The question that trips up employed physicians

More employed physicians now work alongside nurse practitioners and physician assistants than at any previous point in the history of organized medicine. Whether you run a panel with an NP seeing established patients in your absence, share inpatient rounds with a PA, or formally supervise a team of advanced practice providers, the wRVU accounting is rarely spelled out clearly in anyone's contract.

The short answer is: billing rules determine who gets the wRVU credit, and those rules differ entirely depending on whether the visit happens in your office or inside a hospital. A family medicine physician working alongside an NP in an outpatient clinic operates under a completely different set of rules than a hospitalist sharing rounds with a PA on an inpatient unit. The CPT code — and its wRVU value — is often the same. Who gets credited for it is not.

In the office: incident-to billing can put the wRVU credit in your column

When a non-physician practitioner (NPP) sees a patient in an outpatient office setting, Medicare offers two billing options. The NPP can bill under their own National Provider Identifier (NPI) at 85% of the Medicare Physician Fee Schedule. Or, if certain conditions are met, the supervising physician can bill under their own NPI at 100% of the PFS — a billing arrangement known as incident-to.

When incident-to billing is used, the wRVU credit is attributed to the billing provider: the supervising physician. This is consequential for pay. A level 4 established outpatient visit carries 1.92 wRVUs under the 2026 CMS Physician Fee Schedule whether the physician or the NP performs it. Under incident-to billing, those 1.92 wRVUs appear in the physician's productivity report. Under NPP billing, they go to the NP.

Requirements for incident-to billing

The conditions for incident-to billing are specific, and any one missing element disqualifies the claim from this approach:

• Established patient, established condition. The physician must have personally performed an initial service for the condition being treated and must remain actively involved in the patient's ongoing care. A new problem that the physician has not yet evaluated does not qualify — the NP must bill that encounter under their own NPI.
• Direct supervision by the physician. The physician must be physically present in the office suite and immediately available throughout the encounter. As of the 2026 CMS Physician Fee Schedule, CMS permanently extended direct supervision to include real-time audio-visual telecommunications — a physician supervising remotely via live video can satisfy this requirement for most services. Audio-only is not sufficient. Note that this virtual supervision allowance does not apply to surgical services with a 10-day or 90-day global period indicator.
• Office or clinic setting only. Incident-to billing is not available in hospital settings. The moment the patient is admitted or the visit occurs in a hospital outpatient department or emergency department, different rules apply entirely.

When these conditions are satisfied and the practice bills incident-to, the physician receives the wRVU credit. When they are not — new problems, new patients, or visits where the physician is not present in the suite — the NPP bills under their own NPI and takes the wRVU credit with them.

In the hospital: split/shared billing and the "substantive portion" rule

Hospital-based physicians and hospitalists work in a world where incident-to billing does not exist. When a physician and an NPP both contribute to the same patient encounter on the same day in a facility setting — inpatient, hospital outpatient, or emergency department — Medicare's split/shared visit rules govern who bills and who gets the wRVU credit.

For calendar year 2026, CMS defines the substantive portion of a split/shared visit as either:

• More than half of the total time the physician and NPP spend combined on the encounter, or
• A substantial part of the medical decision-making for the visit.

Whoever performs the substantive portion bills for the visit. If the physician performs the substantive portion and bills under their NPI, the practice receives 100% of the MPFS rate and the physician receives the wRVU credit. If the NPP performs the substantive portion, the NPP bills under their own NPI at 85% of the MPFS rate — and the wRVU credit goes to the NPP.

The downstream effect on physician compensation is direct. A hospitalist managing 15 patients per shift alongside a PA — where the PA routinely handles the initial assessment and the physician performs a brief attestation — may find that a substantial share of the day's wRVUs are attributed to the PA rather than to the physician. In a pure production pay model or a base-plus-production contract where the physician carries a wRVU threshold, that attribution pattern matters enormously.

Why this affects your paycheck — and your threshold

The wRVU credit question has two distinct compensation consequences, and they can cut in opposite directions depending on your situation.

In office settings with incident-to billing, the physician's wRVU total can include production that was clinically performed by an NP or PA. A physician who supervises an NP seeing 10 established patients in a morning session while the physician is seeing their own panel in an adjacent room may receive wRVU credit for all of those visits under incident-to rules. This can make a physician's raw wRVU number look higher than their personal clinical output alone would suggest — and it can push them above a bonus threshold they would not have crossed on their own volume. Whether the employer's compensation system actually passes through those wRVUs is a contract question, not a CMS question.

In hospital settings with split/shared rules, the dynamic often reverses. If NPPs routinely handle the time-intensive portions of inpatient rounds while the physician reviews charts and provides a brief attestation, a growing share of the hospital's billable encounters may end up attributed to the NPPs. A hospitalist physician holding an annual wRVU threshold of 4,000 — set when they were the sole rounding provider — may find that threshold increasingly difficult to meet as APP colleagues take the substantive portions of split visits.

This is not a theoretical concern. Some hospitalist and cardiology practices have seen estimates suggesting that shifting split/shared attribution more aggressively to NPPs could redirect a substantial portion of facility wRVU production. Whether that affects your individual compensation depends on how your employer's system attributes and counts those wRVUs internally.

What to ask about before you sign — or renegotiate

Employment contracts almost never address APP wRVU attribution clearly. Most contracts say something like "physician will be paid X dollars per wRVU based on the employer's billing system" — which leaves the employer with significant discretion over exactly which encounters count. The following questions are worth raising explicitly:

1. Are incident-to services credited to my wRVU total? If your NP sees patients in your office and your practice bills incident-to under your NPI, do those wRVUs appear in your production report? Some employers credit them fully; others track by rendering provider (the actual performer) and exclude them. Neither approach is universal — ask for the written policy.
2. In hospital settings, how are split/shared wRVUs attributed between me and my APP colleagues? Is attribution based on who billed, who spent more time, or the employer's internal tracking? If the NP typically performs the majority of a split visit, are those wRVUs assigned to them or to you?
3. Is there a supervision stipend, and does it offset any wRVU credit I might otherwise be forgoing? Some contracts offer a separate dollar-amount stipend for supervising APPs rather than — or in addition to — including their production in your wRVU tally. If you are expected to supervise two NPs while maintaining your own panel, a stipend may be more transparent and predictable than relying on attribution rules.
4. Is my wRVU threshold set assuming I work independently, or does it account for APP collaboration? A threshold calibrated to an independent physician's full-time solo output is different from one set for a physician working in a team model where some production is shared.
