A Florida nurse practitioner’s practice authority runs on one of two tracks: a written protocol with a supervising physician that defines exactly what you may do, or autonomous registration under Section 464.0123 that lets you work independently in primary care. The track you’re on sets your clinical scope, your prescribing limits, and whether you can sign documents like death certificates. Of Florida’s roughly 65,000 licensed ARNPs, about 13,470 have taken the autonomous route; the rest practice under protocol.
The Two Pathways at a Glance
Chapter 464 of the Florida Statutes governs both pathways. Under a supervisory protocol, your legal authority is whatever a Florida-licensed physician or dentist has written into a document kept onsite at every location where you practice. Under autonomous registration, you drop the protocol but accept a narrower clinical lane, higher insurance requirements, and additional continuing education.
Neither pathway lets you do everything a physician does. Both carry hard statutory limits around controlled substances, surgery, and medical marijuana certification. The differences between the two tracks are specific enough that practitioners regularly miscount what their license actually permits.
What You Can Do Under a Supervisory Protocol
Working under a protocol, you can take health histories, perform physical assessments, order diagnostics including lab work and imaging, diagnose health problems, plan treatment with the patient, initiate referrals, and coordinate ongoing care. You can start, adjust, or discontinue therapies for uncomplicated acute illnesses and manage patients with stable chronic conditions.1Florida Board of Nursing. ARNP Protocol Format
The protocol itself is the ceiling. Your scope has to match the supervising practitioner’s specialty area, and anything the protocol doesn’t authorize, you cannot do. If the protocol covers family practice, your authority ends at the conditions and treatments listed there. The supervising physician doesn’t have to be onsite but must be reachable by phone or other communication device when off-site. In a group practice, you need a protocol with at least one physician in the group, and the group may designate one physician to sign on behalf of the others listed.1Florida Board of Nursing. ARNP Protocol Format
The supervising physician has to notify the Board of Medicine that the supervisory relationship exists. That filing is the physician’s responsibility, but if it never happens, both parties have a compliance exposure.
One boundary catches protocol-based NPs who assume otherwise: you cannot sign death certificates or certify cause of death. That authority belongs to physicians, physician assistants, and autonomous ARNPs. A 2025 bill (CS/HB 647) proposed extending it to protocol-based ARNPs providing hospice care, but as the file stands, the restriction holds.
What Changes Under Autonomous Practice
Autonomous registration became available January 1, 2019. It lets you practice without a supervisory protocol, but only within primary care, which Florida defines as family medicine, general pediatrics, and general internal medicine. Certified nurse midwives who register as autonomous can also provide midwifery services, with out-of-hospital intrapartum care requiring a written patient transfer policy for emergencies.
Who Qualifies
To register, you must have logged at least 3,000 hours of clinical practice under a supervisory protocol, have no disciplinary action on your license within the preceding five years, and have completed 3 graduate-level semester hours in differential diagnosis and 3 graduate-level semester hours in pharmacology within the past five years.2Justia. Florida Code 464.0123 – Autonomous Practice by an Advanced Practice Registered Nurse
Autonomous registrants also have to carry professional liability coverage of at least $100,000 per claim with a minimum annual aggregate of $300,000, or hold an irrevocable letter of credit in the same amounts. Protocol-based ARNPs don’t face that statutory mandate.2Justia. Florida Code 464.0123 – Autonomous Practice by an Advanced Practice Registered Nurse Autonomous ARNPs also owe an extra 10 hours of approved graduate-level coursework per renewal cycle on top of standard continuing education.3Florida Board of Nursing.

What You Gain
Within primary care, autonomous ARNPs pick up authorities that protocol-based NPs don’t have:
- Admitting patients to healthcare facilities, managing their inpatient care, and discharging them, unless federal law or rule prohibits it.
- Providing signatures, certifications, and verifications that would otherwise require a physician’s sign-off, including filing death certificates and certifying cause of death.
What Autonomy Doesn’t Cover
Two statutory lines hold even for autonomous ARNPs. You cannot perform any surgical procedure beyond subcutaneous procedures. And you cannot issue physician certifications for medical marijuana under Section 381.986, which restricts that authority to MDs and DOs licensed under Chapters 458 or 459.4Florida Senate.

Prescribing Authority and Controlled-Substance Limits
Florida ARNPs can prescribe, dispense, and order any drug authorized within their protocol, including controlled substances listed under Chapter 893. To prescribe controlled substances, you need a graduate degree from a program that included training in specialized practitioner skills, plus a federal DEA registration number.5Justia. Florida Code 464.012 – Licensure of Advanced Practice Registered Nurses
Schedule II Caps
Schedule II prescriptions are capped at a 7-day supply. The cap does not apply when a psychiatric nurse, as defined in Section 394.455, prescribes psychiatric medications within a protocol established with a psychiatrist.6Florida Senate. Florida Statutes 464.012 – Licensure of Advanced Practice Registered Nurses
A separate administrative rule tightens that limit further for acute pain. Florida Administrative Code Rule 64B9-4.017 sets a 3-day default supply for Schedule II opioids prescribed for acute pain. Any deviation requires documented clinical justification in the patient’s record.7Legal Information Institute (LII) / Cornell Law School. Fla Admin Code Ann R 64B9-4.017 – Standards for the Prescribing of Controlled Substances for the Treatment of Acute Pain Practitioners who know about the 7-day statutory cap sometimes miss that the 3-day acute-pain rule overrides it.
Other Prescribing Restrictions
Psychiatric controlled substances for patients under 18 may be prescribed only by ARNPs who are also certified psychiatric nurses.6Florida Senate. Florida Statutes 464.012 – Licensure of Advanced Practice Registered Nurses ARNPs are prohibited from prescribing controlled substances in registered pain management clinics. And no ARNP, autonomous or otherwise, can certify a patient for medical marijuana; that authority sits exclusively with qualified MDs and DOs.4Florida Senate. Florida Statutes 381.986 – Medical Use of Marijuana
Owning a Clinic as a Nurse Practitioner
Florida does allow ARNPs to own medical clinics. Under Section 400.9905, a clinic staffed by licensed health care practitioners can qualify for an exemption from separate clinic licensure if it’s wholly owned by one or more licensed practitioners or their immediate family members, and if at least one practitioner-owner supervises the business activities and bears legal responsibility for the entity’s compliance with federal and state law.8Florida Senate. Florida Code 400.9905 – Definitions
An ARNP can own and operate a clinic without a physician co-owner, provided the ownership and supervision structure meets the statute. For autonomous ARNPs in primary care, this is a practical route to full practice independence, though separate licensing and billing rules outside Chapter 464 still apply.
Penalties for Practicing Outside Your Scope
The Board of Nursing treats scope violations seriously, and the penalties climb sharply from a first offense to a second.
For practicing beyond your authorized scope or failing minimum standards of acceptable nursing practice, a first offense can run from a reprimand with a $250 fine and mandatory continuing education up to a $500 fine with probation. A second offense ranges from a reprimand with a $750 fine and suspension up to license revocation.9Legal Information Institute (LII) / Cornell Law School. Fla Admin Code Ann R 64B9-8.006 – Disciplinary Guidelines, Range of Penalties, Aggravating and Mitigating Circumstances
For violating a board rule or failing a legal obligation such as practicing without a proper protocol, a first offense runs from a letter of concern with a $100 fine and continuing education up to a $250 fine with probation. A second offense ranges from a reprimand with a $500 fine and suspension up to a $750 fine and revocation.9Legal Information Institute (LII) / Cornell Law School. Fla Admin Code Ann R 64B9-8.006 – Disciplinary Guidelines, Range of Penalties, Aggravating and Mitigating Circumstances
The board can also require a personal appearance, impose supervised probation, or order professional treatment. Aggravating factors like patient harm or a pattern of violations push penalties toward the top of each range. The fines are not what ends careers; the suspensions and revocations do.
