A Medical Office Assistant (MOA) is a healthcare administration professional who works primarily in outpatient clinical environments such as family physician offices, specialist practices, walk-in clinics, physiotherapy centres, dental offices, and other privately operated healthcare facilities. MOAs are the administrative backbone of medical clinics, ensuring that day-to-day operations run efficiently so that physicians and other clinicians can focus on patient care.
In British Columbia, MOAs handle a combination of administrative and, in some settings, basic clinical support tasks. On the administrative side, they schedule patient appointments, manage physician calendars, maintain patient health records in electronic medical record (EMR) systems, process Medical Services Plan (MSP) billings, handle patient inquiries by phone and in person, and manage correspondence between the clinic and specialists, hospitals, and diagnostic imaging facilities.
In clinics where MOAs are trained for clinical support, they may also greet and prepare patients for examination, obtain patient health histories, record vital signs such as blood pressure and pulse, administer routine vaccines under physician supervision, and process lab requisitions and specimen handling. The specific scope of an MOA’s clinical duties depends entirely on the employer, the MOA’s training, and the applicable provincial regulations.
MOAs are often the first and last person a patient interacts with during a clinic visit, making their communication skills, professionalism, and compassion critical to the patient experience. A skilled MOA creates an environment where patients feel welcomed, informed, and well-cared-for even before they see the physician.
What Is a Unit Clerk?
A Unit Clerk, also known as a Ward Clerk or Health Unit Coordinator, is a healthcare administration professional who works in hospital inpatient settings. Unit Clerks are stationed at nursing station desks on hospital wards, in emergency departments, intensive care units, surgical units, maternity floors, and other specialised hospital departments.
The Unit Clerk role is fundamentally different from the MOA role in both environment and function. Rather than supporting a single physician or small clinical team, Unit Clerks support entire hospital units that may include dozens of nursing staff, multiple attending physicians, residents, and allied health professionals. The administrative coordination performed by Unit Clerks keeps these complex, high-acuity clinical environments functioning safely and efficiently.
Core Unit Clerk responsibilities include receiving and processing physician orders for laboratory tests, medical imaging, medications, specialist consultations, and patient transfers. Accurately transcribing and entering these orders into hospital information systems is one of the most critical functions a Unit Clerk performs, as errors in order processing can directly impact patient safety.
Unit Clerks also coordinate patient admissions, bed assignments, and discharge paperwork, manage unit communication including answering phones and relaying urgent messages, direct family members and visitors, prepare patient charts and forms, and maintain accurate records of patient location and status within the unit. The role requires exceptional attention to detail, strong communication skills, and the ability to manage multiple competing priorities simultaneously in a high-pressure hospital environment.
5 Key Differences Between Medical Office Assistant and Unit Clerk
- Work Setting and Environment. This is the most fundamental difference between the two roles. MOAs work in outpatient, private clinic settings that operate on scheduled appointment-based models. The work environment is typically calm and structured, with predictable patient flow and regular business hours. Unit Clerks, by contrast, work in busy inpatient hospital units where the pace is fast, unpredictable, and high-stakes. Hospitals operate continuously, and hospital units experience constant patient movement, physician rounds, emergencies, and administrative activity throughout the day and night.
- Patient Interaction and Acuity. MOAs interact with ambulatory patients who are walking in for routine or semi-urgent appointments. These patients are generally stable and capable of communicating their needs independently. Unit Clerks interact with hospitalised patients who are often seriously ill, recovering from surgery, experiencing acute medical crises, or nearing the end of life. The emotional weight of working with this patient population is considerably different and requires a greater degree of sensitivity and composure.
- Physician Order Processing. One of the defining responsibilities of the Unit Clerk role is receiving and processing physician orders — a function that MOAs in clinic settings do not typically perform. Physician orders in a hospital setting direct nursing and allied health staff to carry out specific tests, treatments, medications, and procedures. Unit Clerks must be able to interpret medical abbreviations, understand common diagnostic and treatment terminology, and enter orders accurately and quickly into hospital information systems like Meditech, Epic, or Cerner.
- Billing and Insurance Processing. MOAs in BC clinics are responsible for managing Medical Services Plan (MSP) billing, processing third-party insurance claims, and handling patient payment transactions. This billing knowledge is a core competency developed in MOA training programs. Unit Clerks in hospital settings do not typically handle billing, as hospital financial operations are centralised in separate billing and coding departments. The administrative focus for Unit Clerks is on clinical coordination rather than financial processing.
- Shift Work Requirements. Most MOA positions follow standard business hours, Monday through Friday, with some positions in walk-in clinics or urgent care requiring evening or weekend availability. This schedule makes the MOA role well-suited for individuals who need predictable daytime hours. Unit Clerk positions in hospitals require shift coverage 24 hours a day, 7 days a week, 365 days a year. New Unit Clerks typically begin on evening, night, or weekend shifts and earn preferred daytime scheduling through seniority under collective agreements.
Detailed Duties of a Medical Office Assistant
The day-to-day responsibilities of an MOA are varied and require a blend of administrative expertise, clinical knowledge, and interpersonal skill. A typical day might begin with reviewing the physician’s appointment schedule, confirming upcoming bookings with patients by phone or automated reminder, and preparing patient charts in the electronic medical record system.
As patients arrive, the MOA greets them, verifies their personal and health card information, collects updated health history as needed, and ensures they are comfortably seated in the waiting area. Throughout the day, the MOA manages the flow of patients in and out of examination rooms, communicating with the physician about wait times, urgent patients, and scheduling changes.
Between appointments, the MOA processes physician referral letters, prepares lab and diagnostic imaging requisitions, receives and files incoming reports from laboratories and specialists, and handles a steady stream of patient phone calls requesting prescription refills, appointment bookings, test result information, and general health inquiries.
Detailed Duties of a Unit Clerk
A Unit Clerk begins their shift by reviewing the patient census for the unit, confirming which patients are present, identifying any pending admissions or expected discharges, and ensuring that patient charts and tracking systems are up to date from the previous shift.
Processing physician orders is a constant and critical activity throughout the shift. When a physician writes new orders — whether during rounds, after an emergency assessment, or in response to changing patient condition — the Unit Clerk must transcribe these orders promptly and accurately into the hospital information system. Orders for blood work, imaging studies, medications, physiotherapy consults, and patient transfers each follow specific workflows that the Unit Clerk must know well.
Coordinating patient admissions involves receiving notice from the emergency department, surgical suite, or other hospital areas that a patient is being transferred to the unit, preparing the physical and electronic chart, notifying the charge nurse, and ensuring the bed space and necessary equipment are ready. Discharge coordination involves generating discharge paperwork, arranging follow-up appointments, coordinating with pharmacy for discharge medications, and communicating with family members or community care providers as directed by the nursing team.
Unit Clerks answer the unit phone continuously throughout their shift, directing calls to the appropriate nurse or physician, relaying urgent messages, and responding to inquiries from patients’ family members. They maintain the physical order of the nursing station, ensure patient charts are complete and filed correctly, and support the nursing team with a wide range of administrative tasks that keep the unit running efficiently.
Training and Education: MOA vs Unit Clerk Programs in BC
Both careers are accessible through diploma and certificate programs at career colleges and community colleges across BC, making them excellent options for individuals seeking to enter the healthcare field without committing to a multi-year university degree.
Medical Office Assistant Programs at institutions like WCC (wcc.ca) typically run 8 to 12 months for certificate or diploma completion. These programs cover core subjects including medical terminology, human anatomy and physiology, electronic medical records and practice management software, MSP billing and insurance processing, clinical office procedures, professional communication, and medical ethics and privacy law. Graduates complete a practicum placement in a real clinic setting that provides hands-on experience and often leads directly to employment.
Unit Clerk Programs similarly run 4 to 12 months depending on the institution and program structure. Core subjects include hospital information systems, medical terminology and abbreviations, physician order transcription, patient flow management, healthcare privacy and legislation, hospital communication standards, and professional conduct in healthcare settings. Some hospitals and health authorities also offer on-the-job Unit Clerk training for candidates with related backgrounds, though formal program completion is generally preferred.
Both programs emphasise hands-on computer skills, given that electronic health records and hospital information systems are central to both roles. Graduates of strong programs should be comfortable navigating multiple software platforms and adapting quickly to new systems as technology evolves.
Salary Comparison: MOA vs Unit Clerk in BC
Compensation for both roles varies by employer, region, years of experience, and whether the position is part-time or full-time. The following ranges reflect current market conditions in BC in 2025.
Medical Office Assistants working in private physician offices and clinics typically earn between $20 and $28 per hour. Entry-level positions in small family practices tend toward the lower end of this range, while experienced MOAs in specialist offices, large multi-physician clinics, or administrative leadership roles earn toward the higher end. Annual salaries for full-time MOAs range from approximately $40,000 to $55,000.
Unit Clerks working within BC health authorities (Vancouver Coastal Health, Fraser Health, Interior Health, etc.) earn between $24 and $32 per hour under the collective agreements negotiated by the Hospital Employees Union (HEU). These wage grids are transparent and predictable, with step increases based on years of service leading to maximum rates after approximately 8 to 10 years of continuous employment. Full-time Unit Clerks earn annual salaries ranging from approximately $48,000 to $62,000, with additional earnings possible through overtime and shift differentials.
While Unit Clerk positions generally offer higher hourly wages, the requirement for shift work including evenings, nights, and weekends is an important consideration. The predictable daytime schedule of most MOA positions holds significant value for many individuals, even at a somewhat lower hourly rate.
