The short answer for Missouri. An RN may administer injectables and infusions only after a good faith exam by a qualified provider.
A good faith exam is a clinical evaluation by a licensed provider, before treatment, establishing that the treatment is appropriate for that patient. What differs between states is who is allowed to perform it, whether it may happen remotely, and what has to be documented. This page sets out what we have verified for Missouri against primary sources, and says so plainly where a question is unsettled.
Who may perform the good faith exam in Missouri
An RN may administer injectables and infusions only after a good faith exam by a qualified provider.
Medical director. A physician licensed by the Missouri Board of Registration for the Healing Arts. Anyone practising medicine in Missouri — including solely as a medical director overseeing other personnel — must hold a Missouri licence.
Delegation and supervision. APRNs work under a written collaborative practice arrangement that reflects the services actually being delivered. LPNs are generally restricted from injectables.
The gate that catches operators in Missouri
The geographic proximity requirement between the collaborating physician and each APRN. A physician three states away is not a Missouri solution.
Model the proximity rule against your actual locations before you sign a lease or a directorship. It is the most common reason a Missouri arrangement that reads well on paper cannot be delivered.
What makes the exam defensible
Nobody is ever asked to produce a good faith exam on a good day. The request arrives after a complication, a board complaint, an insurance audit or a buyer’s diligence. Five things decide whether what you hand over helps you:
- A qualified practitioner, permitted in that state, actually performed it.
- A real evaluation happened — history, indications, contraindications, and a decision.
- The treatment plan and the order are specific: drug or device, site, dose or settings.
- Informed consent was taken and recorded before treatment, not after.
- The record still exists, unaltered and retrievable, two years later when somebody asks.
Only the first of those is state-specific. The other four fail in exactly the same way in Missouri as everywhere else, and they are where most exam processes actually break — not on the licence question, but on documentation nobody kept.
How Missouri sits on structure
Corporate practice of medicine. Yes. Shares may be issued only to natural persons authorised to render a professional service permitted by the articles, and the corporation renders services only through them.
The exam and the structure are separate questions and they fail separately. A perfectly documented exam performed inside an entity that may not lawfully deliver the service is still a problem, and a clean entity does not save a rubber-stamped exam. See medical direction in Missouri for the structure side.

Frequently asked questions
Who can perform a good faith exam in Missouri?
An RN may administer injectables and infusions only after a good faith exam by a qualified provider.
Can the exam be done by telehealth in Missouri?
That depends on the state rule above and on the treatment. Where we have verified a restriction it is stated on this page; where the position is unsettled we say so rather than guess, and we confirm it with the board before you build a remote funnel.
Does Missouri require a physician medical director?
A physician licensed by the Missouri Board of Registration for the Healing Arts. Anyone practising medicine in Missouri — including solely as a medical director overseeing other personnel — must hold a Missouri licence.
What happens if the exam is not documented?
The exam effectively did not happen. In a complaint, an audit or a sale, an undocumented evaluation is treated as no evaluation — which is why the record, not the call, is the thing you are actually buying.
