DEA Controlled Substance SOP for California Veterinary Practices

Registration and licensing

Your controlled-substance authority in California rests on two credentials you already hold: your California veterinary license and your federal DEA registration. State law ties prescribing authority directly to the professional license — HSC 11150 names the veterinarian among the licensed practitioners who may write or issue a controlled-substance prescription. Beyond that license and the DEA registration, California's controlled-substances law (Division 10 of the Health & Safety Code) imposes no separate state controlled-substance registration on veterinarians, so there is no second "state CS license" to apply for. (That is a verified absence — no Division 10 statute creates such a registration — not an express statement of HSC 11150.) ¹

Your premises must be registered with the Veterinary Medical Board (VMB). Every veterinary premises in California must hold a VMB certificate of registration, and "premises" expressly includes a building, kennel, mobile unit, or vehicle. This premises registration is separate from — and in addition to — the DEA registration your practice holds for each location. It is nontransferable, and if the owner or operator changes you must notify the VMB within 30 days. ²

Written controlled-substance prescriptions to a pharmacy must be on a California security prescription form. When you send a controlled-substance prescription out to be filled by a pharmacy (rather than dispensing in-house), it must be written on a serialized, tamper-resistant "California Security Prescription" form from a state-approved security printer, preprinted with your name, license number, and DEA registration number. In-office dispensing from your own stock does not use these forms. ³

Veterinarians are exempt from California's mandatory e-prescribing law. California requires most prescribers to issue prescriptions electronically, but prescriptions "issued by a veterinarian" are exempt. You may continue to issue written, oral, or faxed prescriptions. ⁴

PDMP or reporting duties

You must register with CURES. Any practitioner authorized to prescribe, order, administer, furnish, or dispense Schedule II–V controlled substances must, upon receiving a DEA registration, apply to the Department of Justice for CURES access. This registration is mandatory for a DEA-registered veterinarian; it is not optional. ⁵

You must report what you dispense — within seven days. For each Schedule II–V controlled substance you dispense from your own stock, your practice is a "dispenser" and must report the dispensing to CURES. Pharmacies and other dispensers have one working day; veterinarians are given a longer window — no more than seven days after the date the controlled substance is dispensed. Controlled-substance prescriptions you send to an outside pharmacy are reported by that pharmacy, not by you. ^{6 7}

You are exempt from the duty to consult (query) CURES. California requires most prescribers to review a patient's CURES history before prescribing and every six months thereafter. That consultation duty "does not apply to veterinarians or pharmacists". You are not required to run a CURES query before prescribing. ⁸

Records, inventory, and retention

California veterinary medical records must be kept for at least 3 years after the animal's last visit. This is longer than the federal 2-year minimum for controlled-substance records, so for records that are both (a CS entry inside a patient chart), follow the longer rule: the VMB's own guidance states records must be kept the greater of 2 years from the DEA record/inventory date or 3 years from the animal's last visit. ^{9 7}

California also requires the medication detail to live in the patient record: the record must contain the treatment plan with "medications, dosages and frequency of use," and "all medications and treatments prescribed and dispensed, including strength, dosage, quantity, and frequency". This is in addition to — not a substitute for — the DEA controlled-substance log and biennial inventory in your CS SOP. ⁹

Radiographs are addressed separately in the regulation: they are the property of the veterinary facility that ordered them, with release and return rules and a duty to document any transfer in the medical record — but the regulation states no express retention period for radiographs; the explicit 3-year rule is written for the records themselves. Practice policy: retain radiographs with the patient record for at least the same 3 years after the animal's last visit. This is a conservative recommended practice that supports the record entries the 3-year rule does cover, not an express regulatory deadline. ⁹
