It depends on the state, and the four states with the most IV lounges give four different answers. Washington lets a certified medical assistant place the line under immediate supervision, and put a drug into it only under direct visual supervision. Texas, since 1 September 2025, requires the person administering elective IV therapy to be a PA, APRN or RN. California’s Medical Board says medical assistants cannot start or disconnect an IV at all. Florida’s statute limits medical assistants to nonintravenous injections. A national IV staffing template is wrong in at least two of those states.
Why this question keeps coming up
An IV lounge’s economics run on throughput, and a medical assistant is the cheapest person who can hold a cannula. The rule in every state is that placing a line and infusing a medication are medical acts that must be either performed by a licensed person or lawfully delegated to an unlicensed one. The states differ on whether that delegation is allowed, and on what supervision it needs.
State by state
| State | May a medical assistant place the IV? | May a medical assistant administer through it? | Supervision | Authority |
|---|---|---|---|---|
| Washington | Yes, an MA-C may establish an IV line for diagnostic or therapeutic purposes without administering medication | Only IV injections of diagnostic or therapeutic agents under direct visual supervision | Placing the line: immediate supervision, practitioner on the premises and available. Administering: direct visual supervision, practitioner physically present and within visual range | RCW 18.360; ch. 246-827 WAC |
| Texas | Not for elective IV therapy: administration is delegated only to a PA, APRN or RN under adequate physician supervision | No | Prescribing or ordering may be delegated to a PA or APRN; administering to a PA, APRN or RN | Tex. Occ. Code ch. 172 (HB 3749), eff. 1 September 2025 |
| California | No. “Medical assistants cannot start or disconnect IV’s or administer injections or medication into an IV” | No | Not applicable; the act is outside the MA scope | Medical Board of California FAQ; Bus. & Prof. Code 2069 |
| Florida | Not as an intravenous act: the statute lists venipunctures and nonintravenous injections | No | Direct supervision and responsibility of a physician for permitted tasks | Fla. Stat. 458.3485 |
| Rhode Island | The statute requires assessment by a licensed practitioner before any service and treats standing orders as insufficient; RIDOH guidance governs IV businesses | Per RIDOH guidance | Licensed practitioner assessment first | R.I. Gen. Laws ch. 23-105; RIDOH guidance |
Washington: two acts, two supervision tiers
Washington’s statute is the most permissive and the most precise. An MA-C may establish an intravenous line for diagnostic or therapeutic purposes without administering medications, and may administer intravenous injections of diagnostic or therapeutic agents under the direct visual supervision of a health care practitioner. Placing the line needs immediate supervision, meaning a practitioner on the premises and available for immediate response. Putting a drug in needs direct visual supervision, meaning physically present and within visual range. In the room those feel like one task. In the statute they are two, and the difference is the drug. The Washington rules in detail cover the staffing checklist.
Texas: Jenifer’s Law changed the answer
Before September 2025, Texas IV lounges relied on the general delegation authority in Occupations Code chapter 157 to use medical assistants. HB 3749, known as Jenifer’s Law, added chapter 172 after a patient death following IV therapy at a med spa. Under it, a physician may delegate the act of prescribing or ordering elective IV therapy to a PA or APRN acting under adequate physician supervision, and may delegate administering it to a PA, APRN or registered nurse under adequate physician supervision. Medical assistants are not on the list. A Texas IV lounge staffed by MAs is operating on a rule that was superseded a year ago. The Texas delegation changes run through the rest of the 2025 rewrite.
California and Florida: the answer is in the definition
California does not need a special IV statute because the Medical Board has answered the question directly: medical assistants cannot start or disconnect IVs or administer injections or medication into an IV. They may give intradermal, subcutaneous and intramuscular injections after a licensed person verifies the medication and dose, under the supervision rules in Business and Professions Code 2069. The IV route is simply not in the list.
Florida’s medical assistant statute, 458.3485, lists what a medical assistant may do under the direct supervision and responsibility of a physician, and the injection line reads “performing venipunctures and nonintravenous injections.” A venipuncture to draw blood is in; an intravenous injection is out by the word “nonintravenous.” Florida IV hydration clinics therefore staff administration with RNs or above.
The evaluation is a separate question everywhere
Who places the line is the second question. The first is who decided this patient should receive this infusion. That is a good faith exam by a physician, NP or PA, before the bag is hung, and no state lets a medical assistant perform it. Rhode Island writes it into its med spa and IV guidance: assessment by a licensed practitioner before any service, and standing orders do not create the relationship. Texas puts responsibility for the order on the physician. An IV lounge that has solved the staffing question with RNs and not the evaluation question has solved half the problem.
What this means for you
Match the staffing model to the state, not the other way round. In Washington, an MA-C model works if a practitioner is on the premises for every placement and within visual range for every administration, which is a rota, not a policy. In Texas, replace MA administration with RN, PA or APRN administration now; chapter 172 has been in force since 1 September 2025. In California and Florida, medical assistants do not touch the IV, so the RN is your floor. In every state, staff the evaluation with a prescriber before the first bag.

Frequently asked questions
Can a medical assistant start an IV in Texas?
Not for elective IV therapy. Since 1 September 2025, Texas Occupations Code chapter 172 allows a physician to delegate administering elective IV therapy only to a PA, APRN or registered nurse under adequate physician supervision, and ordering it only to a PA or APRN. Medical assistants are not included.
Can a medical assistant start an IV in California?
No. The Medical Board of California’s medical assistant guidance states that medical assistants cannot start or disconnect IVs or administer injections or medication into an IV. They may give intradermal, subcutaneous and intramuscular injections after a licensed person verifies the medication and dosage.
Can a medical assistant start an IV in Florida?
Florida Statutes 458.3485 limits medical assistants to venipunctures and nonintravenous injections under the direct supervision and responsibility of a physician. Drawing blood is permitted; starting an IV or injecting through one is not within the listed duties.
Can a medical assistant start an IV in Washington?
Yes, with conditions. Under RCW 18.360 a medical assistant-certified may establish an IV line without administering medication under immediate supervision, meaning a practitioner on the premises and available, and may administer IV injections of diagnostic or therapeutic agents only under direct visual supervision, meaning a practitioner physically present and within visual range.
Who can legally run an IV hydration clinic?
Ownership rules vary by state, but the clinical requirements are consistent: a licensed prescriber evaluates each patient and orders the infusion, and a person the state permits administers it, which in Texas, California and Florida means an RN or above. Rhode Island additionally licenses med spas and IV therapy businesses under its Medical Spas Safety Act.
