A medical director, a supervising physician and a collaborating physician are three different legal jobs. The first is mostly a contract title. The second and third are statutory roles with duties written into state law, often with numbers attached. An operator who signs a “medical director agreement” in a state that needs a supervising or collaborating physician has bought a title and left the legal requirement unfilled.
The three roles, defined by who created them
Medical director is a role created by contract, or in a minority of states by a facility statute. Florida attaches it to licensed health care clinics, where the director must agree in writing to accept legal responsibility for listed duties (Fla. Stat. 400.9935). Tennessee attaches it to its med spa registry. Elsewhere it means whatever the agreement says, and no statute tells the physician what to do.
Supervising or delegating physician is a role created by the medical practice act. The physician delegates medical acts to others and remains responsible for them. Texas is the model: a physician may delegate under Occupations Code chapter 157, the Medical Board’s delegation rules sit at 22 TAC 169.25 through 169.29, and the delegating physician’s name and license number must be posted in every treatment room (169.28). Georgia’s version is the delegating physician who signs an APRN’s nurse protocol agreement under O.C.G.A. 43-34-25.
Collaborating physician is a role created by the nurse practice act. The physician does not delegate to the nurse practitioner; the NP practices under their own license within a collaborative agreement, and the physician’s duties are defined by that agreement and the nursing board’s rules. New York, Alabama, Mississippi, Pennsylvania and Kentucky all use this model, each with different arithmetic.
What each state actually requires
| State | Role the statute creates | The obligation, in the statute’s own numbers | Authority |
|---|---|---|---|
| Texas | Delegating physician | Written order responsibility; physician, PA or APRN present or immediately available; name and license posted in every treatment room | Occ. Code 157; 22 TAC 169.27, 169.28 |
| Georgia | Delegating physician | Signed nurse protocol filed within 30 days; annual review; combined cap of eight APRN protocols and PA job descriptions; within 50 miles or principal place of practice in-state | O.C.G.A. 43-34-25(g) |
| Florida | Supervising physician (APRN protocol) | APRN practices within an established written protocol maintained on site; no physical-presence requirement | Fla. Stat. 464.012(3) |
| New York | Collaborating physician | Written practice agreement and protocols; NPs past 3,600 hours may instead maintain documented collaborative relationships | Educ. Law 6902(3) |
| Alabama | Collaborating physician | Present for at least 10% of a newer CRNP’s scheduled hours; quarterly meetings after two years or 4,000 hours; remote sites visited at least twice a year | Ala. Admin. Code 540-X-8-.08 |
| Mississippi | Collaborating physician | Monthly review of 10% or 20 charts, whichever is fewer; quarterly face-to-face meeting; physician practices in-state 20 hours a week or 80 a month, telemedicine excluded | 30 Miss. Admin. Code Pt. 2630, Rule 1.3 |
| Pennsylvania | Collaborating physician | CRNP collaborative agreement kept at the primary practice location, copy filed with the Bureau of Professional and Occupational Affairs | 49 Pa. Code 21.285 |
| Kentucky | Collaborating physician | CAPA-NS required for non-scheduled prescribing; may be discontinued after four years of prescribing under one | KRS 314.042; 201 KAR 20:057 |
| Illinois | Collaborating physician, until FPA | APRN may practice without collaboration after 250 hours of CE or training and 4,000 hours of clinical experience | 225 ILCS 65/65-43 |
| Arizona | None required | APRNs practice independently; collaboration with a physician as needed | A.R.S. tit. 32 ch. 15 |
Two things stand out. First, the collaborating-physician states write numbers: hours, percentages, chart samples, meeting cadences. Second, the delegating-physician states write locations: on the wall, on site, within 50 miles. A contract titled “medical director” that mentions neither is not describing the job the state created.
Why the confusion costs money
An operator in Mississippi hires a “medical director” on a flat fee with no chart-review clause. The nursing board’s rule requires the collaborating physician to review 10% or 20 charts every month and meet the NP face to face every quarter, and to practice in the state at least 20 hours a week. The physician is in Texas. The NP has no lawful collaboration and every prescription written under the arrangement is exposed. Mississippi’s monthly chart review is one rule; every collaboration state has a version.
The reverse failure is a Texas clinic that signs a “collaborating physician agreement” borrowed from a New York template. Texas does not use that model. The Texas physician is a delegating physician whose name belongs in every treatment room and who is responsible for the written order under 169.27. The New York template mentions none of it.
Which one your clinic needs
Work through it in this order:
- Who is the prescriber? If it is a physician, you need a medical director in the contractual sense and possibly a supervising physician for RNs and unlicensed staff. If it is an NP or PA, go to step 2.
- What model does the state use for that prescriber? Delegation (Texas, Georgia, Florida’s APRN protocol), collaboration (New York, Alabama, Mississippi, Pennsylvania, Kentucky, Illinois until FPA), or independence (Arizona, and Illinois or New York after the hour thresholds).
- What are the numbers? Pull the rule and write every hour, percentage, distance and cadence into the agreement as a deliverable with a named owner.
- Does anything else require a named physician? Facility statutes (Florida clinics, Tennessee and Indiana registries, Connecticut’s named provider under Conn. Gen. Stat. 19a-903c), pharmacies, device makers and carriers. Those requirements survive even in an independence state.
The result is often that a clinic needs two things in one person: a collaborating or delegating physician to satisfy the practice act, and a medical director to satisfy everyone else. Both sets of duties belong in the same agreement, separately listed.
The vocabulary problem in your own documents
Titles leak. A “supervising physician” in an MSA, a “collaborating physician” in the NP’s agreement, a “medical director” on the website and a “physician of record” on the pharmacy account can be four names for one person or four claims that nobody has reconciled. Boards read all four. The glossary keeps our own usage consistent, and the discipline is worth copying: one title per statutory role, used the same way in every document.
What this means for you
Identify the model your state applies to your prescriber before you draft anything, then title the agreement by that model, not by the industry’s habit. Copy the state’s numbers into the contract as scheduled obligations. If your state uses collaboration, confirm the physician can meet the in-state, presence and chart-review requirements from where they actually live and work, because a physician in the wrong state cannot collaborate at all. If your state uses delegation, plan for the physician’s name on the wall and their availability during every hour the clinic treats. See what medical direction involves in Texas and in Georgia for the two delegation models side by side, and the Pennsylvania collaborative agreement for the collaboration model.

Frequently asked questions
What is the difference between a medical director and a supervising physician?
A medical director is a contractual or facility-statute role: the physician accountable for a clinic’s clinical operations. A supervising or delegating physician is a medical-practice-act role: the physician who delegates medical acts to others and is responsible for them, as in Texas Occupations Code chapter 157. One person often holds both, but the duties come from different laws.
What is a collaborating physician?
A physician who enters a collaborative agreement with a nurse practitioner under the state’s nurse practice act. The NP practices under their own license; the physician’s duties are set by the agreement and the nursing board’s rules. Alabama requires presence for 10% of a newer CRNP’s hours, Mississippi requires monthly chart review, and New York requires a written practice agreement until the NP passes 3,600 hours.
Does a nurse practitioner need a supervising physician?
It depends on the state’s model. In delegation and collaboration states, yes, under a protocol or collaborative agreement. In full-practice states such as Arizona, no. Illinois and New York release NPs from the requirement after hour thresholds: 250 hours of training plus 4,000 clinical hours in Illinois, 3,600 hours in New York.
Can the same physician be medical director and collaborating physician?
Yes, and it is common. The agreement should list the duties separately, because they come from different sources: the facility or contract duties on one side, and the nursing board’s numbers on the other. A physician who cannot meet the collaboration numbers from where they practice cannot hold that half of the role.
Does the title on the contract matter legally?
The title does not change the law, but a wrong title usually signals a wrong document. A Texas clinic with a “collaborating physician agreement” has probably borrowed a template from a collaboration state and left out the Texas delegation duties, including the posting requirement in 22 TAC 169.28.
