You’ve probably met a medical office assistant at your local clinic before.

They make it easier to handle appointments, confirm paperwork, and pick up test requisitions. Now picture yourself in that role, welcoming patients, preparing records, and being part of the essential care team.

So, what would you do each day as a medical office assistant? How do you become an MOA, and what opportunities can this career open? Let’s find out.

Core Responsibilities: What Does a Medical Office Assistant Do?

As a medical office assistant, you’ll serve as the link between patients, medical staff, and office operations.

You could work in a

  • private clinic,
  • dental or optometry office,
  • community health centre, or
  • long-term care home.

Your day may shift between

  • supporting patients,
  • managing records,
  • coordinating tests,
  • handling referrals, and
  • following up with healthcare providers.

This variety shows how broad MOA duties can be, allowing you to support patients and staff in many different ways.

Patient Care and Communication

You’ll handle patient communication at every stage of their visit. Before appointments, connect by phone or email to confirm schedules, answer questions, or provide instructions.

When patients arrive, welcome them, help with forms, and update records for the medical team. After the appointment, continue with follow-ups such as sending reminders, sharing paperwork, or coordinating referrals.

These clinical interactions create a welcoming experience for patients and support medical staff in providing effective care.

Administrative & Financial Duties

In addition to patient care, you’ll take on various clinic administration and financial duties.

Your role will include

  • medical office billing for patients and insurance providers,
  • updating correspondence such as exam notices or referral forms, and
  • coordinating with specialists for referrals.

You’ll also send lab samples for analysis, record and compile patient information, and print prescriptions.

By keeping the clinic organized, you make it possible for medical staff to give patients their full attention.

Clinical and Office Management Support

You’ll also play a key role in clinical and office management. Each day, you’ll be updating electronic health records, pulling together paperwork for diagnostic tests, or typing out a physicians’ notes.

In hospitals, you may also work as a unit clerk. Here you will handle order entry as well as patient admissions, transfers, and discharges.

What does this mean in practice? Patients receive timely care and attention because healthcare providers focus on treatment, and departments work together effectively. You help create an environment where medical teams can excel and patients can thrive.

These could include

How Do You Become a Medical Office Assistant?

To become a medical office assistant, you need training that builds practical skills and knowledge of healthcare practices.

Employers look for these skills:

  • electronic health records management,
  • medical terminology,
  • medical office procedures, and
  • effective communication.

Educational Requirements and Training Programs

The Sundance College Medical Office Administration – Health Unit Coordinator diploma program will equip you with both the administrative and clinical skills.

You’ll learn

  • medical terminology,
  • anatomy,
  • transcription,
  • electronic health records,
  • billing,
  • diagnostic testing,
  • pharmacology basics, and
  • professional communication skills.

Online learning is paired with a practicum in a healthcare setting such as a clinic or community health centre. There you will apply what you’ve learned and develop the workplace experience employers want.

That’s exactly what Kimberly C., a graduate of Sundance College’s Medical Office Administration program, experienced:

During my practicum, I worked in the electronic medical records (EMR) system and created spreadsheets. Because of my program, I already had a strong understanding of electronic medical records, which helped me fit right in.

By training hands-on in the essential functions of a medical office administrator, you’ll be ready to excel from day one.
