Can a medical assistant work as a CNA?
Medical assistants (MAs) and certified nursing assistants (CNAs) both play essential roles in patient care, but their job descriptions, training requirements, and certifications are quite different. Many people with a medical assisting background wonder if they can work as CNAs without returning to school. The short answer is sometimes—but it depends on your state’s regulations.
The Key Difference Between a Medical Assistant and a CNA
A medical assistant works primarily in outpatient and clinic settings. They perform a mix of clinical and administrative duties such as:
Taking patient vital signs
Assisting with minor procedures
Administering medications (where permitted)
Drawing blood or performing lab tests
Handling scheduling, billing, and medical records
A certified nursing assistant, however, works mainly in hospitals, nursing homes, or long-term care facilities. CNAs focus on direct personal care, including:
Bathing, dressing, and feeding patients
Helping with mobility and transfers
Taking and recording vital signs
Assisting nurses with basic bedside care
While MAs often have more technical training, CNAs specialize in bedside support and daily living assistance—skills that are critical in inpatient settings.
Can a Medical Assistant Work as a CNA Without Extra Training?
In most states, a medical assistant cannot legally work as a CNA without obtaining CNA certification, even if they have similar or more advanced skills. That’s because the CNA title is a state-licensed designation, regulated by the state’s nursing board or department of health.
To work as a CNA, you must:
Complete a state-approved CNA training program (typically 4 to 12 weeks).
Pass the state competency exam, which includes both a written test and a clinical skills assessment.
Be placed on your state’s nurse aide registry.
Even though medical assistants have comparable healthcare knowledge, they still need to meet these state-specific CNA requirements to legally work under the CNA title in hospitals or long-term care facilities.
When Can a Medical Assistant Work in a CNA Role?
In some states or facilities, an experienced medical assistant may be hired for CNA-like duties under different job titles, such as “patient care technician” or “nursing assistant,” without formal CNA licensure—especially in outpatient clinics or rehabilitation centers.
However, these exceptions depend entirely on local regulations and the employer’s discretion. Most hospitals and nursing homes that bill Medicare or Medicaid require officially certified CNAs for compliance reasons.
Should a Medical Assistant Get CNA Certified?
If you already have a medical assistant background and want to work in a hospital or nursing home, obtaining CNA certification is straightforward and often takes only a few weeks.
Advantages include:
Expanding job opportunities in hospitals and elder care facilities.
Gaining bedside care experience that complements clinical training.
Meeting state licensing requirements for long-term care facilities.
Many MAs complete a short CNA bridge program or simply take the CNA exam after demonstrating equivalent skills.
Which Job Is Better?
While both jobs are valuable, medical assisting usually offers higher pay and more career flexibility. CNAs earn about $38,000 to $41,000 per year, while medical assistants average $45,000 to $48,000 annually, according to 2025 data from the U.S. Bureau of Labor Statistics.
Medical assistants also enjoy more predictable schedules, working mostly in outpatient clinics, while CNAs often work nights, weekends, and holidays in hospital settings.
However, CNAs gain more hands-on experience with patient care, which can be an excellent stepping stone for those planning to become registered nurses (RNs) or licensed practical nurses (LPNs).
The Bottom Line
A medical assistant cannot automatically work as a CNA unless they complete the CNA certification process required by their state. Although both roles share similar patient care skills, they fall under different licensing boards and serve distinct functions in the healthcare system.
If you are a medical assistant seeking to expand your job options, earning CNA certification is quick and affordable—and it can make you eligible for hospital-based and long-term care positions that MAs typically cannot hold.
Key Takeaways
Medical assistants and CNAs perform different duties in different settings.
Most states require CNA certification before you can legally work as a CNA.
Some facilities may hire medical assistants for CNA-like roles under different titles.
MAs earn more on average, but CNAs gain more bedside experience and nursing exposure.
If your career goals include working in hospitals or pursuing nursing in the future, earning both credentials can offer the best of both worlds—strong clinical skills, flexible job options, and steady career growth.
