Controlled Substances Part 3: Prescribing and Dispensing Flashcards
A Rx for a controlled substance for a legitimate medical purpose may only be issued by a physician (MD/DO), dentist (DDS/DMD), podiatrist (DPM), veterinarian (DVM), mid-level practitioner (MLP) or another registered practitioner who is:
- Authorized to prescribe controlled substances by the jurisdiction or state in which the practitioner is licensed to practice
- Registered or exempt from DEA registration
- An agent or employee of a hospital or institution acting in the normal course of business under the DEA registration of the hospital or institution
Physicians, dentists, veterinarians, podiatrists, and optometrists are healthcare providers who can prescribe controlled substances independently within their scope of practice. MLPs must prescribe…
under a physician-directed protocol
Each DEA number is unique and is assigned to an individual healthcare provider or an institution. The DEA number permits the individual to write controlled substances prescriptions and authorizes an institution to order and manage controlled substances. Each DEA number is randomly generated and consists of the following:
- Starts with 2 letters
- First letter: identifies the type of practitioner or institution (i.e. registrant type)
- Second letter: first letter of the prescriber’s last name
- Letters are followed by 7 numbers
Last number is the “check digit”
If a practitioner is authorized to prescribe narcotics (such as buprenorphine) for opioid addiction treatment, the practitioner will receive a DATA 2000 waiver unique identification number (UIN). The number is the same as…
the practitioner’s DEA number, except that the letter “X” replaces the first letter.
Prescribers in a hospital or other institution, including medical interns, residents, and visiting physicians, can prescribe medication under the DEA registration of that hospital or institution. The hospital or institution will assign a specific internal code number to each practitioner authorized to prescribe. The internal code number will follow…
the last number of the hospital’s DEA number.
First letter of DEA number for each registrant type:
- A/B/F/G: Hospital, clinic, practitioner, teaching institution, pharmacy
- M: Mid-level practitioner (e.g. nurse practitioner, PA, optometrist)
- P/R: Manufacturer, distributor, researcher, analytical lab, importer, exporter, reverse distributor, narcotic tx program
- X: DATA-waived practitioner
In order for a Rx to be considered valid, it must be issued in the usual course of professional tx for a legitimate medical purpose. The condition being treated must be one that the prescriber would be expected to treat. The pharmacist has a corresponding responsibility to…
ensure a controlled substance Rx is valid prior to filling. A pharmacist is not required to dispense a Rx if he/she has concerns about the legitimacy.
Pharmacists should be aware of potential “red flags” when filling controlled substances Rxs to prevent drug abuse and diversion. Additional signs of drug abuse or misuse may include:
irregularities on the face of the Rx
prescriptions for unusually large quantities
or an initial Rx for a strong opioid
NABP “Red Flags” of Diversion:
- Frequent requests for early refills
- Prescriber and/or patient located an unusual distance from pharmacy
- Patient profile reveals multiple prescribers for duplicate therapy (eg, “doctor shopping”)
- Similar or identical prescriptions for multiple patients from same prescriber (eg, “pill mill”)
- Prescription is not within the prescriber’s scope of practice (eg, opioid analgesic from a psychiatrist)
- Patients presenting to the pharmacy in groups
- Unusual patient behavior (eg, nervous demeanor)
- Patient pays cash for an opioid Rx
- Use of street slang to refer to a medication
- Patient is prescribed a “drug cocktail” (eg, opioid + benzodiazepine + muscle relaxant)
- A pending federal or state action against prescriber
Many drugs that are used illicitly, including opioids, are stolen from another family member. Community pharmacist that dispense schedule II, III, and IV drugs must have medication lock boxes or medication locks available for purchase. The products should have a locking mechanism, such as password or key and they should be displayed near the pharmacy. Pharmacies where a licensed pharmacist is the majority owner and manager of no more than…
4 pharmacies are exempt from this law
The Controlled Substance Utilization Review and Evaluation System (CURES) is California’s Prescription Monitoring Program (PDMP). Prescribers and pharmacists can access CURES to review all schedule II-V drugs that have been prescribed and dispensed for a given patient. A prescriber can request from CURES a list of…
all patients that have designated them as their prescriber. A patient report lists all scheduled drugs the patient has received, the prescribers, the dispensing pharmacist, and other dispensing information.
Each pharmacy must…
submit dispensing data for schedule II-V drugs to CURES within one working day after the Rx was dispensed.
All California pharmacists with active licenses must be registered to access CURES.
All California pharmacists with active licenses must be…
registered to access CURES.
Prescribers must check CURES to review a patient’s history for the past 12 months before prescribing schedule II-IV drugs for the first time and at least 6 months thereafter. Pharmacists are not mandated, but are…
highly encouraged, to check CURES before dispensing schedule II-IV prescriptions.
A practitioner must review a patient’s history in the CURES database no earlier than 24 hours, or on the previous business day, before…
prescribing, ordering, or administering a schedule II-IV drug for the first time, and every 6 months if the drug is still being used.
There are some exceptions (eg, a CURES review is not required for veterinarians).
All controlled substance prescriptions are valid for 6 months and must include the prescriber’s DEA number. All controlled substance prescriptions must be…
dated and signed by the prescriber on the date it is issued to the patient.
Pre-signing prescription blanks is illegal.
Pharmacists should not fill prescriptions that are suspected to be pre-signed.
Any agent of the prescriber (eg, nurse or office staff) can orally or electronically transmit a Rx for a schedule III-V drug. The name of the agent…
transmitting the Rx must be recorded.
In order to fill a controlled substance from an out-of-state prescriber, the prescription must meet the controlled substance Rx requirements of the state in which the prescriber practices, and the prescriber must be registered with the DEA. The schedule of the drug will determine if the prescription can be dispensed directly to the patient at the pharmacy or mailed to the patient:
- Schedule II drugs: a California pharmacy can fill the Rx, but it can only be delivered (mailed) to an out-of-state patient (ie. the drug cannot be dispensed directly to the patient at the pharmacy)
- Schedule III-V drugs: a California pharmacy may dispense the Rx directly to the patient or deliver it by mail
A California security form must be used for all written controlled substances prescriptions (schedules II-V), with a couple of exceptions. Prescribers can write a Rx for both controlled and non-controlled drugs on the security forms or…
they can choose to use separate forms for each type.
A California security Rx form must have the following features:
- The word “void” appears across the front of the Rx when photocopied or scanned due to heat exposure
- A chemical void protection that prevents alteration via chemical washing
- A watermark is printed on the back of the Rx blank that reads “California Security Rx.” Watermarks are not duplicated by copy machines.
- A feature printed in the thermochromic ink which reacts to changes in temperature. Commonly, if a thermochromic image is touched or blown on it will disappear and reappear after it cools. This effect is not duplicated by copy machines.
- An area of opaque writing that causes the writing to disappear if the Rx is lightened.
- A description of the security features included on each form.
- Six quantity check-off boxes printed on the form: 1-24, 25-49, 50-74, 75-100, 101-150, 151 and over.
- Quantity boxes must be checked by the prescriber to correspond to the written quantity of the drug)
- A space to designate the units referenced in the quantity boxes when the drug is not in tablet or capsule (eg. mL)
- Statement that the “Prescription is void if the number of drugs prescribed is not noted.”
- The preprinted name, licensure category, license # and DEA # of the prescriber
- Check boxes that indicate the number of refills ordered
- The date of issue
- A check box indicating the prescriber’s order not to substitute
- A check box by each prescriber’s name when a Rx form lists multiple prescribers. A prescriber who signs a multiple prescriber form will need to check the box by his or her name
- An identifying number assigned to the approved security printer by the Department of Justice
- A unique serial number on each security form, which permits the form to be traced. The # has 15 digits (3 letters, followed by 12 numbers). The prescriber’s serial numbers are reported to CURES.
Each batch of security Rx forms has a lot # printed on the form. The forms…
are printed sequentially, beginning with the number one.
Hospitals often have physicians from the surrounding communities who are granted privileges to see their patients at the hospital. Many hospitals have medical residents rotating through the facility for short periods of time. Both types of prescribers need to write prescriptions, but may not have their own forms for each hospital in which they work. For this purpose, the boards of medicine and pharmacy permit a designated prescriber at a facility that has >25 physicians to order security Rx forms for their facility that do not include:
• pre-printed prescriber information:
- prescriber’s name
- category of licensure
- license number
- DEA number
- Address of the prescribing practitioner
These security forms will be signed out by the designated prescriber in a record book that includes the name to whom they are given, the category of license and number, the DEA number, and the quantity of security forms issued. The record must be kept in the health facility for 3 years.
A Rx for a controlled substance is exempt from using a security form in 2 instances:
- A patient is terminally ill (i.e. life expectancy ≤ 1 year) and the Rx is for medication to manage pain/other symptoms of the terminal illness
• The prescriber must write “11159.2 exemption” on the Rx form used - During a declared emergency when the California Board of Pharmacy has issued a notice of this exemption:
• The prescriber must write “11159.3 exemption” or a similar statement indicating the patient is affected by the declared emergency
• No more than a 7-day supply can be dispensed for a schedule II drug
• Prescriptions filled pursuant to this exemption cannot be refilled
A pharmacy can accept schedule III-V prescriptions verbally (over the phone) if the pharmacist reduces the Rx to writing (i.e. writes the Rx on the pharmacy’s Rx form). The prescription must include all information required for…
a valid Rx (with the exception of the prescriber’s signature). Oral prescriptions for schedule II drugs are not valid except in emergency situations.
Faxed prescriptions are acceptable for schedule III-V drugs as long as all the information required for a valid Rx is included for a valid Rx is included and the prescriber…
manually signs the fax before sending it to the pharmacy. Prescribers should use a regular Rx form to write for schedule III-V drugs before faxing it to the pharmacy. If the prescriber uses a security form, the text “VOID” (written in thermochromic ink) can appear due to the heat emitted by the fax machine during transmission. This is acceptable to fill as long as the pharmacist validates the faxed Rx by contacting the prescriber’s office for verification.
In general, faxed prescriptions for schedule II drugs cannot serve as the original Rx. However, a prescriber can provide a patient with a written Rx for a schedule II drug and fax the same Rx to the pharmacy in order to alert the pharmacy that the patient is on the way. This allows the pharmacy to fill the Rx before the patient arrives. The pharmacist cannot…
dispense the schedule II drug to the patient until the patient brings the written Rx to the pharmacy and it is verified against the faxed Rx before dispensing. It is not acceptable, even as an alert, for patients to fax Rxs to a pharmacy.
The only time a faxed Rx for a schedule II drug is valid is if it’s written for a patient of a licensed skilled nursing facility, an intermediate care facility, a home health agency or a hospice facility. The pharmacist…
will need to produce, sign, and date a hard copy of the Rx before filling it
When prescriptions are electronically transmitted entirely through software, safeguards must be in place to prevent unauthorized persons from hacking into the system and illegally transmitting controlled substance prescriptions. In 2010, the DEA released final rules that permit electronic prescriptions for controlled substances (EPCS) for schedule II-V drugs. Prescribers and pharmacies must use:
- DEA-approved software to send and receive EPCS. The credentials that are permitted for DEA-sanctioned validation will be 2 of the following factors:
- Something you know (eg, password or response to a question)
- Something you have (eg, hard token containing a cryptographic key stored on a hardware device separate from the computer being accessed)
- Something you are (biometric information, such as an iris or fingerprint scan)
Prescribers must use a two-factor authentication method to sign and transmit EPCS. As an alternative to using two-factor authentication to sign the EPCS, the prescriber can use a…
digital certificate. A digital certificate contains the user’s credentials and is issued by the DEA.
