Medical Assistant vs Medical Billing and Coding: What's the Difference?

Medical assisting and medical billing and coding involve different types of healthcare work. According to the U.S. Bureau of Labor Statistics, medical assistants complete a mix of administrative and clinical tasks, working directly with patients as well as behind the scenes.¹ Medical billing and coding generally focuses on healthcare documentation, coding and claims rather than providing direct patient care, according to the American Academy of Professional Coders^® (AAPC^®).² In higher education, these are typically two separate programs, a Medical Assisting Diploma³ and a Medical Billing and Coding Certificate.⁴

In this article, we'll look at what each path involves, how they differ, where they overlap, and how to think about choosing between them.

What Is Medical Assisting?

According to the U.S. Bureau of Labor Statistics, medical assistants complete a mix of administrative and clinical tasks, such as:¹

• Scheduling appointments
• Taking patients' vital signs

Specific duties vary by location, specialty, and employer.

Medical assistants often focus on either clinical or administrative work, though some do both.

Clinical tasks may include:¹

• Recording a patient's medical history
• Measuring vital signs
• Assisting physicians during exams
• Collecting samples for lab testing

Administrative tasks may include:¹

• Helping patients understand their insurance coverage
• Completing forms
• Contacting insurance companies about billing

What Is Medical Billing and Coding?

Medical billing and coding typically centers on the administrative and financial side of healthcare rather than direct patient care.²

According to AAPC^®, medical coding and billing are distinct but related processes, both involved in reporting diagnoses, procedures, and services to insurance payers. Coding means translating a patient's diagnosis and treatment into standardized codes, while billing means using those codes to generate an insurance claim and following it through to payment.²

Medical Assistant vs. Medical Billing and Coding: Key Differences

The differences come down to a few key dimensions:

• Patient contact: Medical assisting typically involves direct interaction with patients, from taking vital signs to assisting with exams.¹ Medical billing and coding generally focuses on healthcare documentation, coding and claims rather than providing direct patient care.²
• Scope of work: Medical assistants may perform both clinical and administrative tasks.¹ Medical billing and coding professionals focus specifically on the administrative and financial side of care: coding and claims.²
• Program length: At Rasmussen University part of American Public University System (“Rasmussen University”), the Medical Assisting Diploma can typically be completed in as few as 12 months,³ while the Medical Billing and Coding Certificate can typically be completed in as few as 9 months.⁴
• Entry requirements: According to Rasmussen University, most coding positions are not considered "entry level"; a combination of education and work experience is typically required to attain a coding position. Similarly, coders, especially those who are new to the field, should not expect to find a position where they can work from home. Most coding positions require onsite work.⁴
• Certification: Medical assistants typically prepare for certifications such as the Certified Medical Assistant or Registered Medical Assistant exams.³ Medical coders may pursue the American Health Information Management Association's Certified Coding Associate credential or, with experience, the Certified Coding Specialist credential.⁴

How Medical Assisting and Medical Billing and Coding Overlap

Despite their different focus, the two paths share some common ground. According to the Bureau of Labor Statistics, medical assistants' administrative duties can include helping patients understand their insurance coverage, completing forms, and contacting companies about billing.¹ These duties may overlap with some aspects of medical billing and coding work.²

How to Choose Between Medical Assisting and Medical Billing and Coding

According to the Bureau of Labor Statistics, medical assistants benefit from analytical skills, clear communication, compassion, attention to detail, and strong interpersonal skills, since much of the work involves direct interaction with patients who may be in pain or distress.⁵

Medical coding, by comparison, draws more heavily on analytical skills and attention to detail applied to documentation rather than people, along with the integrity to safeguard sensitive patient data.⁶

How To Choose Between Medical Assisting and Medical Billing and Coding

Deciding between the two may come down to how you picture your ideal workday. If you're drawn to hands-on patient interaction alongside administrative work, medical assisting may be worth exploring.

If you're more interested in the technical, detail-oriented side of healthcare, working with records and codes rather than patients directly, consider medical billing and coding.
