What Does a Medical Assistant Do? 

Medical assistants play an important role in the day-to-day operation of many healthcare practices. They help keep medical offices organized while also providing routine clinical support to patients and healthcare providers.

Depending on the healthcare setting, employer, training and applicable regulations medical assistants can have a wide range of responsibilities on both the administrative and clinical sides of healthcare.

What Is a Medical Assistant?

A medical assistant is a healthcare professional who provides administrative, clerical and technical support in medical settings. Unlike nurses, physicians and other licensed healthcare professionals, medical assistants in California are unlicensed. Their responsibilities are limited to services they are appropriately trained and authorized to perform and must be carried out under the supervision required by California law. Medical assistants are commonly found in outpatient healthcare environments, where they may interact with patients throughout different stages of a visit.

Administrative Medical Assistant Duties

Medical assisting often includes responsibilities that help a medical office operate efficiently.

Depending on the employer, administrative duties may include:

• Patient Check-In and Registration
  • Medical assistants may help collect patient information, update records and support the check-in process.
• Scheduling
  • Medical assistants may assist with scheduling appointments and coordinating patient visits.
• Medical Records
  • Maintaining accurate patient information is an important part of healthcare administration. Medical assistants may work with electronic health records and other medical documentation.
• Patient Communication
  • Medical assistants may communicate with patients regarding appointments, office procedures and other routine administrative matters.
• Insurance and Office Procedures
  • Depending on the employer and position, medical assistants may also assist with administrative processes related to insurance, referrals, billing or other office functions.

The exact administrative responsibilities vary significantly between employers.

Clinical Medical Assistant Duties

Medical assistants may also provide hands-on clinical support.

Depending on their training, authorization and workplace responsibilities, clinical duties may include:

• Taking and recording vital signs
• Preparing patients for examinations
• Obtaining patient histories
• Assisting with examinations and procedures
• Collecting certain laboratory specimens
• Performing phlebotomy after appropriate training
• Performing ECG procedures
• Applying or removing certain bandages and dressings
• Assisting with other routine technical supportive services

California law establishes specific requirements for the training and supervision of medical assistants performing certain technical procedures.

What Medical Assistants Cannot Do

Understanding the limits of the role is just as important as understanding what medical assistants can do.

Medical assistants cannot independently diagnose or treat patients, interpret medical test results or perform procedures that fall outside their legal scope of practice.

For example, California’s Medical Board states that medical assistants may not:

• Start or disconnect IVs
• Administer medications or injections through an IV
• Insert urinary catheters
• Independently perform telephone triage
• Interpret laboratory or skin-test results
• Diagnose a patient’s condition

These restrictions help define the distinction between medical assisting and licensed healthcare professions.

Where Do Medical Assistants Work?

Medical assistants commonly work in outpatient healthcare settings.

Potential work environments include:

• Primary care offices
• Family medicine practices
• Specialty physician offices
• Urgent care clinics
• Community health centers
• Outpatient medical clinics
• Other ambulatory healthcare settings

The work environment can have a significant effect on the day-to-day responsibilities of a medical assistant.

For example, a medical assistant working in a specialty practice may develop experience with procedures and patient populations that differ from those encountered in a primary care office.

What Does a Typical Day Look Like?

A day may involve a combination of administrative and clinical responsibilities. A medical assistant might begin by preparing examination rooms and reviewing the day’s schedule, then help patients check in, take vital signs, update medical histories and prepare patients for their appointments.

Throughout the day, the medical assistant may also assist healthcare providers with routine procedures, document information in the patient’s medical record, collect specimens or perform other duties appropriate to their training and role.

This variety is one reason medical assisting can appeal to people who want a career that combines patient interaction, healthcare knowledge and practical skills.

What Skills Do Medical Assistants Need?

Successful medical assistants need more than clinical knowledge.

Important skills include:

• Communication
  • Medical assistants interact with patients, physicians, nurses, office staff and other healthcare professionals.
• Organization
  • Medical offices can be busy environments. Staying organized is important when managing patient information, schedules and multiple responsibilities.
• Attention to Detail
  • Accurate documentation, patient information and clinical procedures require careful attention to detail.
• Professionalism
  • Medical assistants interact with patients who may be anxious, uncomfortable or unfamiliar with a healthcare environment. Professional and respectful communication is essential.
• Technical Skills
  • Medical assistants need to understand the clinical procedures they are trained and authorized to perform and follow appropriate safety and infection-control practices.

What Do You Learn in Medical Assistant School?

A comprehensive medical assistant program can cover both administrative and clinical areas.

Project Heartbeat’s proposed Medical Assistant Program curriculum includes subjects such as:

• Medical terminology

The proposed program combines 160 hours of classroom and hands-on laboratory instruction with a 160-hour supervised clinical externship.

Is Medical Assisting a Good Healthcare Career?

Medical assisting may be a good fit for people who want to work in healthcare and enjoy a combination of patient interaction, administrative responsibilities and hands-on clinical work. It can also provide exposure to different areas of outpatient healthcare. As medical assistants gain experience, they may discover particular specialties or areas of healthcare that interest them.

As with any healthcare career, prospective students should research the education, responsibilities, employment requirements and career opportunities associated with the profession before enrolling in a program.
