VCPR and Telemedicine Rules in California
California wrote its veterinary telemedicine rule into statute in 2023.
A VCPR exists when the client authorizes the veterinarian, the veterinarian has sufficient knowledge of the animal, and a treatment plan has been communicated — and that sufficient knowledge can come from a synchronous audio-video examination, not only an in-person one.
The relationship cannot be established solely by audio-only communication or a questionnaire.
Once it exists, telehealth faces no video floor, and prescribing caps depend on how it was formed.

At a glance
A VCPR exists if all of the following are met: the client has authorized the veterinarian to assume responsibility for medical judgments, the veterinarian possesses sufficient knowledge of the animal patient to initiate at least a general or preliminary diagnosis, and the veterinarian has communicated a medical, treatment, diagnostic, or therapeutic plan appropriate to the circumstances.
Yes, limited — sufficient knowledge may come from examining the animal patient in person, examining the animal patient by use of synchronous audio-video communication, or making medically appropriate and timely visits to the premises, but the relationship shall not be established solely by audio-only communication or by means of a questionnaire.
Once established, synchronous audio-video communication is not required for telehealth delivery unless the veterinarian determines it is necessary to provide care consistent with prevailing veterinary medical practice.
Telehealth without a VCPR is permitted only to provide advice in an emergency, as defined in Section 4840.5; subdivision (a)'s prescribing prohibition also does not apply where the animal patient is a wild animal or the owner is unknown.
Off an in-person or premises-visit VCPR, a drug's duration is capped at one year from the examination or visit; off a synchronous audio-video VCPR, at six months, and antimicrobials at 14 days of treatment with no refill without an in-person examination.
No controlled substance or xylazine may be ordered, prescribed, or made available unless the veterinarian has performed an in-person physical examination of the animal patient or made medically appropriate and timely visits to the premises where the patient is kept.
AB 1399 (2023), approved by the Governor October 8, 2023, added § 4826.6 effective January 1, 2024.

What actually creates the relationship
California makes the relationship turn on three conditions joined by “all” — client authorization, sufficient knowledge, and a communicated plan — so each one is separately auditable in the record.
The client may authorize an agent to act on their behalf, which matters where a trainer, barn manager, or family member is the one booking the appointment and speaking for the owner.
For an intake policy, the operative questions are whether the authorization and the plan are documented, and which of the knowledge routes in subdivision (b) the file rests on.
The knowledge element is also the piece with a shelf life, because the prescribing caps in subdivision (i) run from the date of the examination or visit that created it.
“A veterinarian-client-patient relationship exists if all of the following conditions are met: (1)The client has authorized the veterinarian to assume responsibility for medical judgments regarding the health of the animal patient. (2)The veterinarian possesses sufficient knowledge of the animal patient to initiate at least a general or preliminary diagnosis of the animal patient's medical condition. (3)The veterinarian has assumed responsibility for making medical judgments regarding the health of the animal patient and has communicated with the client a medical, treatment, diagnostic, or therapeutic plan appropriate to the circumstances.”
How the relationship can start remotely — and where the line sits
Sufficient knowledge may come from an in-person examination, an examination by synchronous audio-video communication, or medically appropriate and timely premises visits — a video exam is a codified establishment path in California, written into the statute rather than left to board discretion.
Two exclusions bound it: the relationship cannot be established solely by audio-only communication, and it cannot be established by means of a questionnaire.
California's own definition of telehealth is broad — it includes two-way audio and the electronic transmission of images and diagnostics — so an audio-only consultation is still telehealth in California; what it cannot do is start the relationship.
Subdivision (f) adds a licensure boundary: only a veterinarian holding a current California license may practice via telehealth on an animal patient located in the state, which is what rules out covering California patients remotely from another state.
“A veterinarian-client-patient relationship shall not be established solely by audio-only communication or by means of a questionnaire.”
Once it exists, telehealth has no synchronous-video floor
Having established the relationship, the statute turns permissive about modality: synchronous audio-video is not required for telehealth delivery unless the veterinarian determines it is necessary to provide care consistent with prevailing veterinary medical practice.
The operating duties attach to every telehealth encounter regardless of modality — informed consent covering the same standard of care, the client's option of an in-person visit at any time, and adverse-reaction follow-up; review of the patient's relevant medical history; the veterinarian's name, contact information, and license number; and a secured alternative way to contact the client if the connection fails.
A practice manager can read subdivision (h) directly as the checklist for the telehealth workflow.
“Synchronous audio-video communication is not required for the delivery of veterinary medicine via telehealth after a veterinarian-client-patient relationship has been established unless the veterinarian determines that it is necessary in order to provide care consistent with prevailing veterinary medical practice.”
The one thing telehealth may do with no VCPR at all
California permits telehealth without a VCPR for exactly one purpose: advice in an emergency, as defined in Section 4840.5.
There is no deferral window that lets telemedicine stand in for the relationship and catch up later — the relationship has to exist before any diagnosis, prescribing, or treatment.
Subdivision (a) adds a narrow companion carve-out of its own: its prohibition on prescribing without a VCPR does not apply where the animal patient is a wild animal or the owner is unknown.
Everything else waits for the relationship.
“A veterinarian is permitted to use telehealth without establishing a veterinarian-client-patient relationship in order to provide advice in an emergency, as defined in Section 4840.5.”
Prescribing caps depend on how the relationship was formed
The prescribing caps split by how the relationship was formed.
A VCPR established in person or by premises visits supports prescriptions of no more than one year from the examination or visit; a VCPR established by synchronous audio-video caps a drug at six months, with no second prescription of the same drug without another examination, in person or by telehealth.
Antimicrobials off a virtual VCPR are tighter still — 14 days of treatment, and no further prescription, including a refill, without an in-person examination.
Controlled substances and xylazine cannot be ordered, prescribed, or made available off a virtual relationship at all, and the board lists repeated controlled-substance prescribing without a Section 4826.6 relationship among its investigative priorities.
Subdivision (i) also directs the veterinarian to notify the client that some drugs may be available at a pharmacy and bars telehealth prescribing for racehorses under California Horse Racing Board jurisdiction.
“The veterinarian shall not order, prescribe, or make available a controlled substance, as defined in Section 4021, or xylazine, unless the veterinarian has performed an in-person physical examination of the animal patient or made medically appropriate and timely visits to the premises where the animal patient is kept.”
The rule is new, and it moved the question into statute
Section 4826.6 arrived with AB 1399, approved by the Governor on October 8, 2023, and took effect on January 1, 2024.
Before that, per the bill's own digest, telemedicine sat in board regulation, which required it to be conducted within an existing VCPR with an exception for emergency advice; AB 1399 carried that structure into statute and added the definitions, the consent and practice duties, and the prescribing caps described on this page.
The bill also defined telehealth and synchronous in the Business and Professions Code and exempted a telehealth-only practice location from premises registration where no in-person examination or treatment occurs, no drugs or equipment are kept, and the required disclosures are published.
Any summary, vendor page, or internal policy written before 2024 describes the superseded regulatory baseline, not this statute.
“"Telehealth" means the mode of delivering veterinary medicine via electronic communication technologies to facilitate the diagnosis, consultation, care management, or treatment of an animal patient, and includes, but is not limited to, synchronous video and audio communication; synchronous, two-way audio communication; and electronic transmission of images, diagnostics, data, and medical information.”
There are two VCPRs, and the federal one does not move
What This Page Does — and Doesn’t — Cover
This page describes California’s own text — Cal. Bus. & Prof. Code § 4826.6, added by AB 1399 (2023), effective January 1, 2024 as read for this series, current as of September 2026, with the provision itself last changed AB 1399 (2023), approved by the Governor October 8, 2023, added § 4826.6 effective January 1, 2024. It does not cover licensure, scope of practice, or the terms of a specific prescription, and it is not a compliance sign-off for a telemedicine service.
VCPR and telemedicine rules are the fastest-moving area this site covers — nine states changed theirs between 2024 and 2026, and bills are live in others. Confirm the current text with the board before you build an intake policy, a prescribing workflow or a remote-care service on it, and read the federal note above alongside it rather than instead of it.
Frequently Asked Questions
Can a California veterinarian establish a VCPR over video?
Yes.
Section 4826.6(b) counts an examination conducted by synchronous audio-video communication as a route to the sufficient knowledge the relationship requires, alongside an in-person examination and medically appropriate and timely premises visits.
Two limits sit on top: the relationship cannot be established solely by audio-only communication or by means of a questionnaire, and the veterinarian must hold a current California license to practice via telehealth on an animal located in the state.
Read the current text of Section 4826.6 and confirm with the Veterinary Medical Board before building a service on it.
Once a California VCPR exists, does telehealth follow-up have to be video?
No. Section 4826.6(d) provides that synchronous audio-video communication is not required after establishment unless the veterinarian determines it is necessary to provide care consistent with prevailing veterinary medical practice, so audio follow-up and electronic transmission of records remain open within an existing relationship.
The statute's operating duties still attach to each encounter: informed consent, medical-history review, disclosure of the veterinarian's name and license number, and a backup contact method.
Verify current expectations with the Veterinary Medical Board.
What can a California veterinarian do by telehealth with no VCPR at all?
One thing: provide advice in an emergency, as defined in Section 4840.5.
California has no mechanism that lets telemedicine substitute for the relationship on a deadline — the relationship has to exist before diagnosis, prescribing, or treatment.
Subdivision (a) separately excludes wild animals and patients whose owner is unknown from its no-VCPR prescribing prohibition, which is a different and very narrow carve-out.
Confirm the current text with the Veterinary Medical Board.
Can a California veterinarian prescribe controlled substances off a virtual VCPR?
No. Section 4826.6(i)(6) bars ordering, prescribing, or making available a controlled substance or xylazine unless the veterinarian has performed an in-person physical examination of the animal patient or made medically appropriate and timely visits to the premises where the patient is kept.
The board also treats repeated controlled-substance prescribing without a Section 4826.6 relationship as an investigative priority.
Check the current rule with the Veterinary Medical Board before relying on any remote-prescribing workflow.
Does satisfying California's VCPR statute make a practice federally compliant?
No, and this is the trap.
The federal VCPR at 21 CFR 530.3(i) is a separate relationship governing extralabel drug use and Veterinary Feed Directives; it requires that the veterinarian has recently seen the animal or visited the premises, and the FDA has said it cannot be met solely through telemedicine.
It applies regardless of what California permits.
Extralabel use is routine, so check both the state statute and the federal rule.
