20 CSR 2220-2.910
Class O: Automated Dispensing Systems (Ambulatory Care)
PURPOSE: This rule establishes licensing standards and require
ments for Class O: Automated Dispensing Systems (Ambulatory
Care).
(1) Definitions.
(A) “Ambulatory prescription dispensing system”—A Class
O automated dispensing system (Class O ADS) used to process,
verify, fill, label, and dispense a completed prescription/med
ication order for patient retrieval from the system using an
electronic verification system.
(B) “Class O automated dispensing system”— A pharmacy
license classification which allows the use of an ambulatory
prescription dispensing system or a prescription pick-up sys
tem as defined by this rule at a specific location. A Class O ADS
does not include an automated system used for compounding
medication, a Class N automated dispensing system, or an au
tomated filling system governed by 20 CSR 2220-2.950.
(C) “Electronic verification system”—An electronic verifica
tion, bar code verification, weight verification, radio frequency
identification (RFID), or similar electronic process or system
process used to verify and ensure medication/prescriptions
have been properly stocked, restocked, loaded, filled, dis
pensed, or labeled.
(D) “Prescription pick-up system”—A Class O ADS that allows
a patient to obtain a filled, labeled, and pharmacist-verified
prescription/medication order placed in the system by or on
behalf of a Missouri-licensed pharmacy for patient retrieval. A
prescription pick-up system does not include a vacuum tube
drug delivery system identified in 20 CSR 2220-2.800.
(E) “Supervising pharmacist”—A Missouri-licensed pharma
cist designated to supervise a Class O ADS while the system is
in operation.
(2) Licensing. Applicants for a Class O ADS pharmacy permit
classification must file an application on a form approved by
the board and pay the applicable fee. A pharmacy Change of
Classification application is required for currently licensed
Missouri pharmacies opting to add a Class O ADS classification
to their existing Missouri pharmacy permit. Application fees to
add or obtain a Class O ADS pharmacy permit shall be waived
for Class N ADS permit holders licensed on the effective date of
this rule for a period of six (6) months from this rule’s effective
date.
(A) A Class O ADS permit may be used to operate all Class O
ADSs located at the address designated on the permit. A Class
O ADS may only be used by the permit holder, and may not be
used to dispense prescriptions/medication orders for multiple
pharmacies.
(B) The appropriate pharmacy permit classification is required
for any pharmacy activities under the board’s jurisdiction
that occur at the Class O ADS site other than operating the
Class O ADS. Class O ADS pharmacies must comply with all
requirements applicable to any additional pharmacy permit
classifications held by the pharmacy, including but not limited
to all applicable security and staff supervision requirements.
A Class J pharmacy permit is required for shared service
activities, as provided in 20 CSR 2220-2.650.
(C) To be eligible for licensure, a Class O ADS must be located
within the permitted address of a Missouri-licensed pharmacy
where pharmacy services other than Class J Shared services,
Class I Consultant services, or Class O ADS services are pro
vided, or at an indoor location where health care services are
regularly provided by a licensed health care provider at the
same location. A Class O ADS must be located at an address
recognized by the United States Postal Service and may not be
located outside of a physical structure.
(D) Applicants may petition the board in writing to approve a
Class O ADS at an alternative location to increase patient access
to medication in an area where access to an ambulatory/com
munity pharmacy is limited. Petition requests must include
documentation or evidence demonstrating how the proposed
Class O ADS location will expand patient access to medication
and promote public health. The board will consider the follow
ing factors when determining petition requests:
1. The availability of pharmacy services in the proposed
Class O ADS pharmacy area;
2. Benefits or risks to patient care;
3. Policies/procedures for ensuring adequate security;
4. The permit holder’s ability to promptly access the Class
O ADS in the event of an emergency, which shall be no more
than thirty (30) minutes;
5. The applicant’s experience and compliance history; and
6. Any other factor that may benefit or adversely impact
public health.
(3) System requirements. A Class O ADS must be maintained
in good working order and in a clean and sanitary manner. If
applicable, a Class O ADS must be cleaned and disinfected on a
regular basis using appropriate materials and agents.
(A) A sign must be conspicuously posted or electronically
displayed on the Class O ADS that clearly identifies the permit
holder’s name, address, the system’s hours of operation, and a
telephone number for contacting the pharmacy during oper
ational hours.
(B) A Missouri-licensed pharmacist must be capable of being
physically present at the approved Class O ADS location within
thirty (30) minutes in the event of an emergency or other sys
tem malfunction.
(C) A video surveillance system must be in place that allows
the pharmacy to physically view the Class O ADS and the Class
O ADS site at all times. A video surveillance system is not re
quired if a pharmacist is present on-site and able to view the
Class O ADS at all times the system is accessible to the public.
(D) Medication must be stored and maintained in a thermo
statically controlled area within temperature and humidity
requirements as provided in the Food and Drug Administration
approved drug product labeling or the United States Pharma
copeia (USP).
(E) At a minimum, temperatures in drug storage areas of the
Class O ADS must be recorded and reviewed daily. Alternatively,
a continuous temperature monitoring system may be used to
comply with this subsection, if the system maintains ongoing
documentation of temperature recordings that promptly alerts
pharmacy staff when temperatures are outside of the required
range and provides the amount of variance.
(F) The Class O ADS system must use an electronic verifica
tion system to electronically verify and ensure prescriptions/
medication orders are properly dispensed to the correct pa
tient. The electronic verification system(s) must be validated by
a properly qualified board licensee or appropriately supervised
board registrant designated by the pharmacy to ensure the
system is functioning properly prior to first use and prior to
restarting the system after an unanticipated system shutdown
or interruption. Additional validation must occur if any modifi
cation to the Class O ADS occurs that changes or alters the dis
pensing or electronic verification process. Validation dates and
results must be documented in writing and readily retrievable.
(G) The Class O ADS permit holder must regularly review sys
tem operations to ensure proper functioning. At a minimum,
a Missouri-licensed pharmacist must visit and review Class O
ADS operations weekly during the first month of system opera
tions and monthly thereafter. The dates of the required weekly
and monthly visits/reviews and the identity of the designated
pharmacist must be documented and readily retrievable at the
request of the board or the board’s authorized designee. The
permit holder shall remain responsible for Class O ADS services
and ensuring proper functioning.
(H) An ongoing and documented quality assurance program
must be established to monitor the performance of the Class O
ADS. The quality assurance program must include procedures
for handling and reporting dispensing errors, system malfunc
tions, and other compliance concerns.
(I) Notification of any dispensing error involving a Class O
ADS that is dispensed to the patient must be submitted elec
tronically or in writing to the board within ten (10) days of dis
covery. The required notification must include the date of the
incident, patient name, description of the error, the applicable
prescription/medication order number or unique identifier,
and any corrective action taken.
(4) Standards of operation. A Class O ADS must be safely and
properly operated at all times in compliance with applicable
state and federal laws, including but not limited to all applica
ble controlled substance laws. Medication must be accurately
dispensed and labeled.
(A) Medication may only be dispensed by a Class O ADS
pursuant to a valid patient-specific prescription or medication
order. A Class O ADS may not be used to dispense prescriptions/
medication for multiple pharmacies.
(B) The Class O ADS must be supervised at all times it is in op
eration by a Missouri-licensed pharmacist who is either phys
ically present at the Class O ADS site or who is supervising via
an electronic system that allows the pharmacist to adequately
view the Class O ADS and supervise all Class O ADS activities.
The required pharmacist supervision may not be delegated to
an intern pharmacist.
1. The supervising pharmacist must maintain full opera
tional control over the Class O ADS whenever the Class O ADS is
in operation, and must be able to terminate or suspend Class O
ADS operations when deemed necessary or appropriate.
2. The required electronic system must provide a
continuous real-time video link to allow the supervising
pharmacist to see the entire Class O ADS site. A two- (2-) way
communication mechanism must also be available that allows
communication between the supervising pharmacist and any
technicians or intern pharmacists present on-site. Medication
may not be dispensed and the Class O ADS may not be operated
if the required video link and audio communication are not
fully functioning.
3. A supervising pharmacist may not supervise more than
two (2) Class O ADSs at a time. The identity of the supervising
pharmacist must be documented and maintained in the su
pervising pharmacy’s records. Licensees may request a waiver
of the supervision limit. The board will consider the factors in
subsection (2)(D) when determining waiver requests.
(C) For Class O ADS prescription pick-up systems, only filled
and labeled prescriptions that have been verified by a phar
macist may be loaded in or dispensed from the Class O ADS
prescription pick-up system, except as otherwise authorized
by law. The entire dispensing process must be fully automated
after the prescription/medication order is loaded into the Class
O prescription pick-up system. No manual manipulation of the
prescription/medication order or the affixed label may occur
after the prescription/medication order is stocked, restocked,
or loaded in the Class O ADS prescription pick-up system.
(D) For Class O ADS ambulatory prescription dispensing
systems, the entire prescription/medication order filling, dis
pensing, and labeling process must be automated and the
required prescription/medication label must be affixed by the
Class O ADS ambulatory prescription dispensing system prior
to dispensing from the Class O ADS ambulatory prescription
dispensing system. No manual manipulation of the prescrip
tion/medication order or the affixed label may occur after the
automated filling process is initiated.
(E) Medication may not be dispensed via a Class O ADS if the
patient or the patient’s authorized designee requests not to use
the Class O ADS.
(5) Patient counseling. An offer to counsel must be made to
the patient or the patient’s authorized representative prior to a
prescription or medication order being dispensed from a Class
O ADS, except as otherwise required by law for Class R remote
dispensing site pharmacies. The offer to counsel may be made
verbally by authorized pharmacy staff or made electronically
via the Class O ADS.
(A) Adequate space and equipment must be available to con
fidentially counsel patients. Live, real-time patient counseling
must be provided if counseling is requested by the patient or
otherwise required. If a pharmacist is not present on-site, two-
(2-) way video and audio technology must be available that
allows the pharmacist and patient to both view and communi
cate with each other. Medication may not be dispensed if the
required video and audio technology is not fully functioning.
(B) Video monitors/screens used for patient counseling or
communication must be a minimum of twelve inch (12") wide
diagonally. Backlighting or other factors that may inhibit video
performance must be taken into account when using video
technology to counsel/communicate with patients.
(C) A sign must be conspicuously posted or continuously
displayed electronically on the Class O ADS informing patients
that a pharmacist will provide counseling either in-person or
via the video/audio system on request. The sign must include
clear instructions for requesting counseling and must be easily
viewed and readable by the public.
(6) Stocking/restocking. Medication must be securely stocked,
loaded, and reloaded in a Class O ADS in a manner that pro
tects against theft or diversion, and in compliance with 20 CSR
2220-2.010.
(A) Only board licensees or registrants may stock, load,
or restock a Class O ADS, as authorized by the supervising
AND INSURANCE
pharmacy’s policies and procedures.
(B) For Class O ADS prescription pick-up systems, a pharma
cist must physically verify that prescriptions/medication orders
have been properly loaded into the Class O ADS prescription
pick-up system. The identity of the verifying pharmacist must
be documented and maintained in the pharmacy’s records.
Alternatively, an electronic verification system may be used
to verify that prescriptions/medication orders have been prop
erly loaded into the Class O ADS prescription pick-up system,
if no manual intervention with the prescription/medication
order occurs after the electronic verification is completed. If
authorized by a pharmacist, intern pharmacists or pharmacy
technicians may load a Class O ADS prescription pick-up sys
tem without a pharmacist present or additional pharmacist
verification if—
1. An electronic verification system is used to verify the
prescription/medication order has been properly loaded into
the ADS system;
2. No manual intervention with the prescription/medica
tion order occurs after the electronic verification required by
this subsection, other than removing the prescription/medica
tion order by authorized pharmacy staff for return/destruction;
and
3. The electronic verification system has been validated
and revalidated as required by subsection (3)(F). Validation
dates and results must be documented in writing and readily
retrievable.
(C) For Class O ADS ambulatory prescription dispensing sys
tems, an electronic verification system must be used to verify
that medication or medication containers have been properly
stocked, restocked, and loaded into the Class O ADS ambula
tory prescription dispensing system. If authorized by a pharma
cist, intern pharmacists or pharmacy technicians may stock, re
stock, or load manufacturer unit of use packages and repacked
containers previously verified by a pharmacist into a Class
O ADS ambulatory prescription dispensing system without a
pharmacist present or additional pharmacist verification if—
1. An electronic verification system is used to verify the
medication has been correctly stocked, restocked, or loaded;
2. No manual intervention with the manufacturer unit of
use package or repacked container occurs after the required
electronic verification required by this subsection occurs,
other than removing the manufacturer unit of use package or
repacked container by authorized pharmacy staff for return/
destruction; and
3. The electronic verification system has been validated
and revalidated as required by subsection (3)(F). Validation
dates and results must be documented in writing and readily
retrievable.
(D) Return-to-stock medication may be returned and reused
as authorized by 20 CSR 2220-3.040 or 20 CSR 2220-2.145 gov
erning multi-med dispensing. No medication shall be returned
directly to a Class O ADS for reissue or reuse by a person not
licensed or registered by the Board of Pharmacy.
(E) The following documentation must be maintained and
readily retrievable:
1. The date and time prescriptions/medication orders are
stocked, loaded, restocked, and removed from the Class O ADS
system;
2. The date and time medications are stocked, loaded, re
