Yes, medical assistants can give injections in NJ, but only if they are certified, only for intradermal, intramuscular, and subcutaneous routes, and only when a physician has examined the patient, delegated the specific injection, and remains on the premises while it is given. The rule lives at N.J.A.C. 13:35-6.4, and each of those conditions has to be met at the same time.1Legal Information Institute. New Jersey Administrative Code 13:35-6.4 – Delegation of Administration of Subcutaneous and Intramuscular Injections and Performance of Venipuncture to Certified Medical Assistants
Which Injections Are Permitted
A certified medical assistant may administer three types of injections: intradermal (just below the skin surface), intramuscular (into a muscle), and subcutaneous (into the fatty tissue under the skin). Between them, these routes cover most routine office injections, including many vaccines, insulin, and drugs like vitamin B-12 or epinephrine auto-injectors.1Legal Information Institute. New Jersey Administrative Code 13:35-6.4 – Delegation of Administration of Subcutaneous and Intramuscular Injections and Performance of Venipuncture to Certified Medical Assistants
Intravenous injections are off-limits entirely. Regardless of the route, the assistant also cannot administer:
- Anything used for allergenic testing or treatment
- Local anesthetics
- Controlled dangerous substances
- Any drug without FDA approval
- Antineoplastic chemotherapy agents, with a single exception for corticosteroids
The corticosteroid carve-out matters in practice because corticosteroids are sometimes grouped with chemotherapy drugs but are widely used for inflammation and pain. A properly delegated corticosteroid injection is allowed; no other drug in that class is.1Legal Information Institute.

Only a Physician Can Delegate the Injection
This is where the regulation trips people up. Under N.J.A.C. 13:35-6.4, only a physician can direct a certified medical assistant to give an injection. “Physician” here means a doctor of medicine (M.D.), doctor of osteopathic medicine (D.O.), or doctor of podiatric medicine. Physician assistants and advanced practice nurses are not on that list.1Legal Information Institute. New Jersey Administrative Code 13:35-6.4 – Delegation of Administration of Subcutaneous and Intramuscular Injections and Performance of Venipuncture to Certified Medical Assistants
The assistant must also work in the same medical practice as the delegating physician. A physician from another practice or facility cannot authorize the injection from a distance.
The Physician Has to Examine the Patient First
Before delegating, the physician personally examines the patient, decides what treatment is appropriate, weighs the risks against the expected benefits for that individual, and specifies every detail of the injection: type, dosage, method, site, and any patient-specific precautions. A blanket standing order is not enough. Each delegated injection has to be tied to a patient-specific examination and treatment decision.1Legal Information Institute. New Jersey Administrative Code 13:35-6.4 – Delegation of Administration of Subcutaneous and Intramuscular Injections and Performance of Venipuncture to Certified Medical Assistants
The Physician Must Stay On the Premises
The physician has to remain on the premises the entire time the medical assistant is carrying out injection orders. On the premises means within reasonable proximity to the treatment room, available to observe the patient, assess the outcome, and step in immediately if something goes wrong, such as an allergic reaction.1Legal Information Institute. New Jersey Administrative Code 13:35-6.4 – Delegation of Administration of Subcutaneous and Intramuscular Injections and Performance of Venipuncture to Certified Medical Assistants
If the physician leaves the building, the assistant must stop giving injections until the physician returns. The physician is responsible for everything the assistant does under their direction, which is why the on-site rule is written the way it is.
What Counts as a Certified Medical Assistant
New Jersey does not let anyone with the title of medical assistant give injections. The regulation defines a “certified medical assistant” through three stacked requirements: an accredited education program, current national certification, and a competency sign-off from the supervising physician.
Education Program
The assistant must have graduated from a post-secondary medical assisting program accredited by the National Healthcare Association (NHA), the Committee on Allied Health Education and Accreditation (CAHEA, succeeded by CAAHEP), the Accrediting Bureau of Health Education Schools (ABHES), or another accrediting agency recognized by the U.S. Department of Education. The program has to include at least 330 clock hours of instruction covering injection techniques, relevant anatomy and physiology, equipment selection, sterile technique, hazards and complications, and emergency procedures.1Legal Information Institute. New Jersey Administrative Code 13:35-6.4 – Delegation of Administration of Subcutaneous and Intramuscular Injections and Performance of Venipuncture to Certified Medical Assistants
Current National Certification
The assistant must hold current certification or registration from an approved body. The regulation lists the American Association of Medical Assistants (CMA), American Medical Technologists (RMA), National Center for Competency Testing, American Medical Certification Association, National Association for Health Professionals, and National Certification Medical Association. The Board of Medical Examiners may approve additional bodies. The credential has to be active; an expired certification takes the assistant out of scope even if the training is still fresh.1Legal Information Institute. New Jersey Administrative Code 13:35-6.4 – Delegation of Administration of Subcutaneous and Intramuscular Injections and Performance of Venipuncture to Certified Medical Assistants
Physician Competency Verification
Even with the diploma and the certification, one more step is required. The supervising physician has to personally determine and document that the assistant is qualified and has reached a satisfactory skill level. At minimum, the physician must verify:
- Ten hours of training in administering injections
- Satisfactory performance of at least ten intramuscular injections
- Satisfactory performance of at least ten subcutaneous injections
- Satisfactory performance of at least ten intradermal injections
The documentation stays with the practice. If the assistant changes employers, the new supervising physician has to make their own competency determination before delegating injections.1Legal Information Institute. New Jersey Administrative Code 13:35-6.4 – Delegation of Administration of Subcutaneous and Intramuscular Injections and Performance of Venipuncture to Certified Medical Assistants
Documentation for Every Injection
The physician has to write the treatment details into the patient’s medical record before the assistant gives the injection. The record must include the type of injection, dosage, method, site, and any patient-specific risk factors, and it must be available to the assistant carrying out the order. The assistant who administers the injection must also be identified by name and credentials in the record each time.1Legal Information Institute. New Jersey Administrative Code 13:35-6.4 – Delegation of Administration of Subcutaneous and Intramuscular Injections and Performance of Venipuncture to Certified Medical Assistants
Charting that leaves out the assistant’s name or the physician’s specific order puts the practice out of compliance, even if the injection itself was clinically appropriate.
What Happens If the Rules Are Broken
The heaviest exposure falls on the supervising physician, because the physician holds the license the Board of Medical Examiners can act against. Under N.J.S.A. 45:1-21, the Board can suspend or revoke a license for gross negligence, repeated acts of negligence, professional misconduct, or failure to comply with any regulation the Board administers.2Justia. New Jersey Code 45:1-21 – Refusal to License or Renew, Grounds
Directing an uncertified assistant to inject, leaving the building while injections continue, or skipping the patient examination before delegating are each violations of N.J.A.C. 13:35-6.4 and grounds for disciplinary proceedings.
The assistant faces a different kind of risk. Medical assistants are unlicensed in New Jersey, so the Board’s disciplinary tools are aimed at the physician, but a patient harmed by an injection given without proper certification, without delegation, or outside the permitted routes can pursue a malpractice or negligence claim against the assistant, the physician, and the practice together.
