Medical Office Assistant

Medical office assistants, also known as medical administrative assistants, are essential in keeping the healthcare system running smoothly. They provide various clerical and administrative services to ensure that the medical office operates efficiently. By managing patient records, scheduling appointments, greeting patients, collecting insurance information, and ensuring necessary paperwork is filled out correctly, medical office assistants help maintain quality patient care while ensuring that healthcare providers can focus on their primary goal of providing excellent medical care.

The first step to becoming a medical office assistant is to obtain the necessary education. Most employers require applicants to have a high school diploma or equivalent. However, some companies may prefer candidates with a post-secondary certificate, diploma, or associate’s degree for medical office assistants. 

Most employers provide on-the-job training, in lieu of or in addition to formal education, to new medical office assistants. During this time, they will learn to perform the various tasks required by the position, such as filing paperwork, scheduling appointments, answering phones, and handling other administrative duties. They will also learn to use the computer programs to manage patient information and run reports. Over time, they may receive additional training on handling billing and coding insurance claims. 

After on-the-job training, education, or both, medical office assistants can earn certification through national organizations such as the National Healthcareer Association (NHA), National Center for Competency Testing (NCCT), and American Medical Technologist (AMT). Earning a  certification demonstrates mastery in the skills necessary to do this job and ensures employers that candidates have attained a high level of aptitude in this field. 

Clinical and administrative medical assistants are currently in very high demand. The Bureau of Labor Statistics (BLS 2022) estimates that between 2021 and 2031, there will be a 16 percent increase in jobs in this field, translating into 117,800 new positions. This is much higher than the national average of 5 percent growth for all jobs. On average, medical office assistants earn $39,740 per year. 

If an entry-level office-based career in healthcare sounds exciting, keep reading to learn more about the typical job duties, top online and in-person programs, and certification options.

Medical Office Assistant Specializations & Degree Types

A degree, diploma, or certificate is not necessary to start a career as a medical office assistant. However, it can be advantageous when applying for work, and some employers may require it. Students can complete a short three-month-long certificate or up to a two-year associate’s degree. Most medical office assistant programs cover the same general topics, although some programs offer additional education in specializations such as billing and coding.  

Admissions Requirements for Medical Office Assistant Programs

Applicants must generally provide proof of a high school diploma or a GED to gain admission into a medical office assistant program. To apply, candidates must typically submit a completed application form with an application fee, a cover letter or personal essay, and letters of recommendation. Proof of immunizations is also typically required for programs with a hands-on externship component.

Some medical assistant programs that are available online have no admission requirements and can simply be purchased and completed by interested students.

Medical Office Assistant Program Accreditation

Medical office assistant programs are typically accredited by the Commission on Accreditation of Allied Health Education Programs (CAAHEP) or the Accrediting Bureau of Health Education Schools (ABHES). Accreditation is important because it ensures that programs meet standards set by industry professionals and that program credits can transfer to other institutions if needed.

However, many programs still need to be accredited but could still be a good option for someone entering this field. These include programs that are approved by the National Center for Competency Testing (NCCT). While not as rigorous as CAAHEP or ABHES programs, and the credits are unlikely to transfer to another institution, these education options will prepare students to sit a national certification exam and can help advance their careers.
