Medical Assistant Job Description: Duties, Skills & Pay

Medical assistants keep outpatient clinics running: they room patients, take vitals and histories, assist with procedures, give injections where state rules allow, and handle the scheduling, records and insurance work between visits. It is the clinic's most cross-trained role.

Duties vary by employer and shift, so always check the individual posting. Typical responsibilities:

• Room patients: history, medications, vitals, chief complaint in the EHR
• Administer immunizations and injections as delegated and allowed by state law
• Perform EKGs, point-of-care tests (strep, flu, A1c) and phlebotomy where trained
• Assist providers during exams and minor procedures
• Schedule appointments, manage check-in/out and answer phones
• Verify insurance and process prior authorizations and referrals
• Sterilize instruments and stock exam rooms
• Relay test results and care instructions as directed

• Postsecondary medical assistant program (diploma or associate) is the common route; some clinics train on the job
• Certification preferred by most employers: CCMA (NHA), CMA (AAMA) or RMA (AMT), plus BLS
• EHR competence (Epic, eClinicalWorks, Athena)
• HIPAA discipline and exact documentation

• Speed with warmth: 20+ patients a day without making anyone feel rushed
• Accurate vitals, injections and specimen handling
• Insurance and prior-authorization follow-through
• Juggling front-office and back-office work
• Bilingual ability is a hiring advantage in many clinics

The U.S. Bureau of Labor Statistics reports a median pay of $45,690 a year (May 2025) for medical assistants, and openings are steady nationwide as outpatient care grows - see our How to Become a Medical Assistant guide for the full outlook and training paths. Specialty clinics (cardiology, dermatology) and lead MA roles pay above the median.

• What is the difference between clinical and administrative medical assistant duties? Clinical work touches the patient (vitals, injections, tests); administrative work runs the schedule, records and insurance. Most postings expect both; lead with the mix the posting emphasizes.
• Do you need certification to be a medical assistant? Most employers prefer or require CCMA, CMA or RMA plus BLS; a few train uncertified hires and fund the exam - see our full guide for the no-experience path.
• Can medical assistants give injections? In most states yes, as delegated by a provider and within state rules; confirm the scope in your state and list your injection competencies on the resume.
