Collaborating physicians and NP practice authority: the staffing cost

Ask a staffing vendor about collaborative practice agreement cost and the answer comes back as a monthly fee per nurse practitioner. That number is real, but it is the small part of the bill. The larger cost is structural. A brand that wants to see patients in every state has to arrange physician oversight wherever the state requires it, keep those arrangements current as providers come and go, and produce the paperwork the moment a board asks for it. For a telehealth brand the question is less what one agreement costs than how many of them a 50-state roster needs, and who carries them.

This post walks through the three practice tiers, what a collaborative agreement actually says, what the arrangements cost by tier, the ratio and chart-review rules that hurt an online clinic in particular, and the arithmetic that decides whether an operator should build a provider network or rent one.

Full, reduced and restricted: what the three tiers mean

The American Association of Nurse Practitioners sorts every state and the District of Columbia into three practice environments, and its map, updated in May 2026, is the reference most operators and vendors use. AANP's definitions, in its own words, run as follows.

• Full practice: state law permits all NPs to evaluate patients, diagnose, order and interpret diagnostic tests, and initiate and manage treatments, including prescribing medications and controlled substances, under the exclusive licensure authority of the state board of nursing.
• Reduced practice: state law requires a career-long regulated collaborative agreement with another health provider in order for the NP to provide patient care, or it limits the setting of one or more elements of NP practice.
• Restricted practice: state law requires career-long supervision, delegation or team management by another health provider in order for the NP to provide patient care.

AANP's public page does not publish a count per tier, and the counts quoted around the industry shift every legislative session as states move between categories, so this article does not give one. The pattern matters more than the tally. In a full-practice state an NP can carry a patient panel alone, though several full-practice states add a transition period of supervised practice before a newly licensed NP practices independently. In a reduced state the NP needs a signed collaborative agreement with a physician before the first patient visit. In a restricted state the physician is a supervisor in the legal sense, with duties the board can audit and a license on the line if the audit goes badly.

For a brand, the tier determines whether a state costs anything beyond the NP's own license. A full-practice state costs the license, the DEA registration if controlled substances are involved, and the credentialing file. A reduced or restricted state costs all of that plus a physician relationship that has to exist on paper before anyone in that state can be seen.

What a collaborative agreement contains

State boards publish templates or minimum contents, and the documents converge on the same parts. The agreement names both parties with license numbers, describes the patient population and conditions the NP will treat, and states which categories of medication the NP may prescribe, including which controlled-substance schedules if any. It sets the consultation rule: when the NP must reach the physician, and how quickly the physician must be reachable. It sets the chart-review rule: how many charts, how often, and whether the physician signs anything. It sets a ratio, if the state has one, and it records where the agreement is kept or whether it is filed with the board. It has a review period, a termination clause, and signatures.

Two details catch first-time operators. The collaborating physician has to be licensed in the state where the NP practices, which for a remote clinic means the state where the patient sits, not where the physician lives. And the agreement does not travel: an NP licensed in four reduced-practice states needs four agreements, possibly with four different physicians, each filed or retained according to that state's rule. The credentialing file has to hold all of it, which is why provider credentialing in a multi-state clinic is a standing function rather than a one-time onboarding task.

Controlled substances add an addendum in many reduced and restricted states, and a separate DEA registration for the NP in each state where prescriptions will be written. Some boards also want the physician's name on the prescription or on the record. A brand that plans to prescribe testosterone or anything else scheduled should plan the agreements around that from the start rather than amending them later.

What it costs by tier

Vendor figures are the only published numbers, so they should be read as vendor figures. One physician staffing vendor's state-by-state guide puts collaborating physician arrangements at $400 to $2,500 per NP per month, and a locum staffing firm's guide puts a telehealth medical director at $500 to $6,000 per month. Neither is an audited market survey. What the ranges do show is the spread, and the spread comes from the tier.

In a full-practice state the direct collaboration cost is close to nothing. Most clinics still retain a medical director for protocols, quality review and the friendly-PC structure, but that person is one salary spread over the whole business rather than a per-state charge. In a reduced state the physician's job is mostly availability and periodic chart review, so the fee sits toward the low end of the vendor range and scales with the chart-review load. In a restricted state the physician is supervising in a way the board can hold against them, so physicians charge more, take fewer NPs, and ask harder questions about the clinic's protocols before signing. The top of the range belongs to restricted states with controlled substances in the plan.

The monthly stipend is the visible line. The invisible lines are the physician's licenses in each state where they collaborate (which the clinic often pays for), malpractice coverage extended to supervisory duties, the legal drafting of each agreement, recruiting time, and replacement cost. When a collaborating physician leaves, every NP under that physician stops practicing in that state until a new agreement is signed, and in some states filed and acknowledged. The lost revenue during that gap is a real cost that never appears on the vendor's price list.

A collaborative agreement is a fixed cost that starts the day the state goes live and continues whether ten patients or none show up there.

Ratio caps and chart reviews in states where NPs need a supervising physician

Ratio caps, chart-review rules and meeting rules all hit an online clinic harder than they hit a brick-and-mortar practice. Several reduced and restricted states limit how many NPs one physician may supervise or collaborate with at once, sometimes by headcount and sometimes by full-time equivalent. A physician who has reached the cap in a state cannot take on the next NP the brand hires, so every hiring wave in that state means another physician license and another agreement.

Chart review is labor. States that require the physician to review a percentage of charts, or a set number per period, turn supervision into a recurring task, and in a clinic doing high volumes of short asynchronous visits the load grows with volume. A physician quoted a flat stipend for a small panel will renegotiate once the marketing works. Meeting and proximity rules are the awkward ones for a remote roster. Some states want periodic meetings between the NP and physician, and a few historically wanted the physician within a certain distance or with a practice site in the state. A remote physician in another time zone satisfies some of these rules by video and others not at all, which is why a state that looks fine on the tier map can still be expensive to open.

The practical consequence is that capacity has to be planned state by state. A brand cannot point a national marketing budget at every state and let visits fall where they may. When a campaign lands in a restricted state, the clinic needs an NP licensed there, a physician licensed there with room under the ratio cap, an agreement on file, and, for controlled substances, DEA registrations for both. If any one of those is missing, the visits queue or get refunded.

Physician assistants are a separate map

PAs are licensed under state medical boards rather than nursing boards, and their rules use different vocabulary, mostly "supervision" and increasingly "collaboration," with the terms of the relationship set at the practice level in a growing number of states. The AANP tiers do not describe PA practice, and a brand that assumes a full-practice NP state is also a low-overhead PA state will be wrong some of the time.

There is also a licensing compact specific to PAs. The PA Licensure Compact's site lists 29 states that have enacted it, and whether compact privileges are being issued yet is something to confirm on that site rather than assume. A roster that mixes NPs and PAs needs two tracking systems for oversight rules, two sets of agreements, and two answers to the question of which states are cheap to open. Many telehealth clinics lean toward NPs for exactly that reason, but the choice should follow the vertical and the state mix, not a habit.

Build the network or rent it

Building the network means recruiting NPs, licensing them in each target state, finding physicians licensed in every reduced and restricted state on the list, negotiating stipends, drafting and filing agreements, extending malpractice, tracking renewals and ratios, and replacing people when they leave. The cost is largely fixed: a monthly stipend per reduced or restricted state, plus licenses, plus the medical director, plus staff time, and it runs whether the state produces volume or not. Adding NPs in a capped state adds physicians. The build-versus-buy guide on this site walks through every line, and the build-versus-buy calculator lets an operator put their own state list and volume assumptions against it.

Renting the network means paying a per-consult price into which someone else has already folded the collaboration overhead across all fifty states and is spreading it over many brands' volume. Tessic Health is one worked example: licensed physicians and nurse practitioners in all 50 states, credentialing and collaborative arrangements handled as part of the platform, $25 flat per completed consult, no revenue share on any plan. The brand pays for consults that happen and does not carry a stipend in a state where nobody has signed up yet.

The break-even is not subtle. A fixed roster only beats per-consult pricing once every reduced and restricted state on the list is producing enough visits to cover its own stipend, licenses and review labor, and once the brand is large enough to absorb a physician's departure without losing a state for weeks. Most brands under a few thousand consults a month are nowhere near that point. Clinician founders who want to keep their own license in the loop can do that on a rented network too, as the page for clinicians describes, without personally becoming the collaborating physician of record in every state.

Questions operators ask

• Does a full-practice state mean no physician involvement at all? For the NP's legal authority, yes. For the business, usually no: in states with corporate practice of medicine rules the friendly PC still needs a licensed owner, protocols still need a medical director, and payers and card processors still ask who is clinically responsible.
• Can one physician cover every reduced and restricted state? Only if licensed in each, under each state's ratio cap, and able to meet each state's review and meeting rules. In practice a national roster uses several physicians, each covering the states where they are licensed.
• What happens to patients when a collaborating physician leaves? In most reduced and restricted states the NP cannot see patients there until a replacement agreement is signed. Scheduled visits in that state pause, prescriptions in flight are handled by the medical director, and the clinic needs a bench of pre-vetted physicians to shorten the gap.
• Is the agreement the same as a medical director contract? No. The medical director sets clinical policy for the whole clinic. The collaborating physician is a state-specific legal relationship with a specific NP. One person can hold both roles, but the documents are different and both have to exist.
• Where can the per-state rules be checked? Each state board publishes its own requirements. The state pages on this site summarize them per state; the tier map from AANP is the fastest way to see which states will carry a collaboration cost at all.

The cost of NP practice authority, then, is a map problem before it is a price problem. Sort the target states by tier, count the reduced and restricted ones, and the fixed monthly cost of a self-built network writes itself. That number, compared with a per-consult rate, is the whole decision.
