Collaborator Fee: Flat Monthly vs. a Percentage of Collections

Does federal law prefer one structure?

No. Nothing in the anti-kickback safe harbor for personal services and management contracts names a payment shape. What it asks is that the methodology for determining the compensation paid to the agent over the term of the agreement be set in advance, consistent with fair market value in arm's-length transactions, and not determined in a manner that takes into account the volume or value of any referrals or business otherwise generated between the parties 1Ref 1Office of the Federal Register (2026).42 CFR 1001.952 — Exceptions (Anti-Kickback Safe Harbors).The six conditions of the personal services and management contracts safe harbor at paragraph (d)(1): written and signed, covering and specifying all services, a term of not less than 1 year, a compensation methodology set in advance and consistent with fair market value, the bar on compensation determined by the volume or value of referrals or federally payable business between the parties, and aggregate services not exceeding what is reasonably necessary..

That wording is recent, and it is why the question has an answer at all. OIG rewrote the paragraph in its 2020 final rule so that the methodology, rather than the aggregate compensation, is what must be set in advance, and the preamble says it is possible to structure an arrangement to fit within the safe harbor by using an hourly rate or other set, verifiable formula 2Ref 2U.S. Department of Health & Human Services, Office of Inspector General (2020).Medicare and State Health Care Programs: Fraud and Abuse; Revisions to Safe Harbors Under the Anti-Kickback Statute, and Civil Monetary Penalty Rules Regarding Beneficiary Inducements.OIG's own explanation that paragraph 1001.952(d)(1) now requires the METHODOLOGY to be set in advance rather than the aggregate compensation, and its statement that an arrangement can be structured to fit the safe harbor using an hourly rate or other set, verifiable formula.. A percentage of collections is a formula. Whether it is verifiable, and whether it lands at fair market value for the services contracted for, are questions the shape of the fee does not settle.

But a safe harbor is all or nothing.

OIG's guide for new physicians puts the standard in one line: to be protected by a safe harbor, an arrangement must fit squarely in the safe harbor and satisfy all of its requirements 3Ref 3U.S. Department of Health & Human Services, Office of Inspector General (2026).A Roadmap for New Physicians: Avoiding Medicare and Medicaid Fraud and Abuse.OIG's plain-language statement that an arrangement must fit squarely in a safe harbor and satisfy all of its requirements to be protected, and that excessive compensation for a consultancy counts as remuneration under the Anti-Kickback Statute.. Missing one condition is not itself an offense, but it leaves the arrangement outside the protection. The same booklet counts excessive compensation for a consultancy as remuneration.

The clause to read slowly is the referral clause, which reaches business otherwise generated between the parties that is payable in whole or in part by a federal health care program 1Ref 1Office of the Federal Register (2026).42 CFR 1001.952 — Exceptions (Anti-Kickback Safe Harbors).The six conditions of the personal services and management contracts safe harbor at paragraph (d)(1): written and signed, covering and specifying all services, a term of not less than 1 year, a compensation methodology set in advance and consistent with fair market value, the bar on compensation determined by the volume or value of referrals or federally payable business between the parties, and aggregate services not exceeding what is reasonably necessary.. Whether a share of a practice's collections touches that language in a specific agreement is a question for a health care attorney with the draft in hand.

The conditions either agreement has to meet

Six conditions, and they fall identically on a retainer and a percentage. The agreement is written and signed. It covers and specifies all of the services to be provided. Its term is not less than 1 year. The compensation methodology is set in advance, at fair market value, and not tied to referral volume or value. The services do not involve counseling or promotion of an unlawful activity. The aggregate services do not exceed what is reasonably necessary 1Ref 1Office of the Federal Register (2026).42 CFR 1001.952 — Exceptions (Anti-Kickback Safe Harbors).The six conditions of the personal services and management contracts safe harbor at paragraph (d)(1): written and signed, covering and specifying all services, a term of not less than 1 year, a compensation methodology set in advance and consistent with fair market value, the bar on compensation determined by the volume or value of referrals or federally payable business between the parties, and aggregate services not exceeding what is reasonably necessary..

The one-year floor turns a pricing preference into a commitment: a structure chosen in the first thin month of a new panel is carried through the twelfth.

Which structure carries the slow month?

The flat fee sits with you and the percentage is shared. A retainer is a fixed monthly cost set against variable collections, heaviest in the months a new panel is still filling and lightest once the schedule is full. A percentage inverts both halves: it costs little in a slow month and keeps rising, with no renegotiation, through every month the practice grows.

Run the visit volume for collaborator fees before signing either one. Divide the monthly retainer by your average net collection per visit and you have the visits each month the fee consumes before anything reaches you. Multiply the percentage against a month of collections you have already banked, not a projection, and compare. Where the two lines cross is a function of your rates, your payer mix and your collection rate, which is why it is arithmetic to run on your own ledger rather than a rule of thumb to borrow.

Run it twice: once on the panel you have this quarter, and once on the panel you expect at the end of a term that runs at least a year.

What counts as collections?

Define the base before agreeing to a percentage of it. Collections can mean cash received, charges billed, or receipts net of refunds and takebacks, and the three produce different bills. Ask whether patient-paid money counts: the no-show fee, a late-cancellation charge, a cash-pay visit, a deposit that is later refunded. Ask whether the rate runs on every payer or only the work the collaboration touches.

Medicare pays an NP 85% of the physician fee schedule amount at the ceiling, so part of that base arrives already discounted. For services furnished on or after January 1, 1998, allowed amounts for the services of a nurse practitioner or clinical nurse specialist may not exceed 85 percent of the physician fee schedule amount for the service, other than assistant-at-surgery work 4Ref 4Office of the Federal Register (2026).42 CFR 414.56 — Payment for nurse practitioners' and clinical nurse specialists' services.Paragraph (c): for services furnished on or after January 1, 1998, Medicare allowed amounts for a nurse practitioner's services may not exceed 85 percent of the physician fee schedule amount, which caps the Medicare portion of any collections base a percentage fee is levied on.. A percentage levied on Medicare collections is a percentage of a number that was capped before it arrived.

Write the definition into the agreement with the same care as the rate. A methodology set in advance is hard to claim for a formula whose base was never written down, and an undefined base becomes a dispute in the first bad quarter.

Does the physician's workload grow with your panel?

In some states it does, and that is the strongest argument for tying the fee to volume. Where a board defines the collaborating physician's minimum duty as a share of the chart volume, the work grows as the panel fills, and a retainer priced for ten patients a week buys the same review at forty. Where the duty is written as a cadence, the floor does not move.

Georgia measures it as a share. The Composite Medical Board's minimum accepted standards require the delegating or designated physician to review and sign 10% of all other patient records at least annually, and to review and sign 100% of patient records for patients receiving prescriptions for controlled substances, at least quarterly after the prescription is issued 5Ref 5Georgia Composite Medical Board (2026).Chapter 360-32 NURSE PROTOCOL AGREEMENTS PURSUANT TO O.C.G.A. SECTION 43-34-25.Georgia's minimum record-review standard: the delegating or designated physician reviews and signs 10% of all other patient records at least annually and 100% of patient records for patients receiving controlled-substance prescriptions at least quarterly, the example of a review duty measured as a share of the panel.. A panel that doubles doubles both counts.

Ohio measures it as a cadence. Its quality assurance standard under a standard care arrangement asks for periodic random chart review, including prescribing patterns and Schedule II prescribing if indicated, at least annually by a collaborating physician 6Ref 6Ohio Board of Nursing (2026).Rule 4723-8-05 | Quality assurance standards..Ohio's quality assurance minimum under a standard care arrangement: periodic random chart review including prescribing patterns and Schedule II prescribing if indicated, at least annually by a collaborating physician, the example of a review duty written as a cadence rather than a share of the panel.. The rule names no share of the panel, so the board's minimum does not rise as the practice grows.

Neither of those is the national rule, and there is no national rule to look up. The lookup is your own board: the nursing board's chapter on the collaborative agreement or standard care arrangement, or, in the states that route this through the medical board, that board's chapter on protocol agreements. Read the review obligation before arguing about price, because what your collaborating physician's monthly fee buys is the duty the state already assigns plus whatever availability the agreement adds.

Terms that outlast the fee argument

Four terms decide more of this than the choice between a retainer and a rate: the notice period, what happens to prescribing when the agreement ends, who carries the state filing costs, and how the fee gets revisited as the panel grows. Put all four in writing, and date the fair market value reasoning while the comparison is still in front of you.

Termination is the expensive one. Prescribing after a collaborator quits is a licensure problem before it is a billing problem, and where a state conditions prescriptive authority on a filed agreement, a replacement has to be found, signed and filed before the current one lapses. A notice period long enough for that is worth more than a point of margin either way.

Filing costs are small, but they are real. In Georgia, filing the APRN protocol agreement with the Composite Medical Board costs $150, paid electronically through the Licensing Gateway, board fees are non-refundable, and the delegating physician is the one who submits it 7Ref 7Georgia Composite Medical Board (2026).APRN Protocol Registration.Georgia's $150 non-refundable board filing fee for an APRN protocol agreement, paid electronically through the Licensing Gateway and submitted by the delegating physician, as a fixed cost that neither fee structure changes.. That is a Georgia figure as of September 2026; the equivalent in your state sits on your board's fee schedule and does not move with the fee structure.

A psychiatric nurse practitioner has one question that comes before price. Settle the psychiatrist requirement for PMHNP collaborators first, since it decides who is eligible to sign at all.

The election is yours to make. Bring three things to it: the draft agreement read against the safe harbor conditions above, your board's review rule, and one banked month of collections with your own net-per-visit worked out. A health care attorney reads the first, your CPA reads the third, and both cost less before the term starts.
