Missouri is the state where a remote medical director genuinely does not work, and the reason is geography written into statute.
Missouri APRNs practice under a collaborative practice arrangement governed by RSMo 334.104, and that statute carries a geographic proximity requirement between the APRN and the collaborating physician. The waivers are narrow and specific: up to twenty-eight days a calendar year for rural health clinics where the arrangement includes alternative plans; APRNs in a correctional center where the two practice within two hundred road miles; and certain telehealth arrangements where services are provided in a rural area of need.
What Missouri actually requires
- A collaborating physician who satisfies the geographic proximity requirement for each APRN. A physician three states away is not a Missouri solution.
- A physician licensed by the Missouri Board of Registration for the Healing Arts — anyone practicing medicine in Missouri, including solely as a medical director overseeing other personnel, must hold a Missouri license.
- A professional corporation whose shares are issued only to natural persons authorized to render a professional service permitted by its articles, under RSMo ch. 356; the corporation renders services only through natural persons permitted to render them.
- Delegation documented so that an RN administers injectables and infusions only after a good faith exam by a qualified provider.
- A written collaborative practice arrangement that reflects the services actually being delivered.
Who may do what in Missouri
| License | What they may do |
|---|---|
| MD or DO | Independent; the collaborating physician and medical director role |
| APRN | Under a collaborative practice arrangement, subject to geographic proximity |
| Physician assistant | Under the applicable supervision arrangement |
| Registered nurse | May administer injectables and infusions under delegation, after a good faith exam |
| LPN | Generally restricted from injectables |
| PC shareholder | Natural persons authorized to render the service named in the articles |
Model the proximity rule against your actual locations before you sign a lease or a directorship. It is the single most common reason a Missouri arrangement that looks fine on paper cannot be delivered.
