What Does a Physician Assistant Do?

A physician assistant delivers medical care across the full spectrum of patient encounters. Trained in the medical model, PAs are educated to examine patients, diagnose conditions, develop treatment plans, prescribe medications, and perform procedures. The role provides healthcare organizations with flexibility: PAs can practice in primary care, emergency medicine, surgery, and dozens of other specialties, often shifting between them over the course of a career.

A typical day for a PA in a family medicine practice begins with chart review, examining the schedule and pre-reading patient histories for the day's appointments. The first patient might be a 62-year-old man presenting for an annual physical. The PA performs a comprehensive examination, reviews medications, orders routine bloodwork (lipid panel, metabolic panel, PSA), and counsels the patient on exercise and nutrition. According to O*NET, physician assistants "examine patients to obtain information about their physical condition" and "obtain, compile, and record patient medical data, including health history, progress notes, and results of physical examination" [3].

The next appointment might be a 28-year-old with a sprained ankle. The PA assesses range of motion, orders an X-ray to rule out fracture, applies a compression wrap, prescribes anti-inflammatory medication, and provides instructions for rest, ice, compression, and elevation. O*NET notes that PAs "perform therapeutic procedures, such as injections, immunizations, suturing and wound care, and infection management" [3].

Between patients, the PA reviews lab results returned from yesterday's orders, calls patients with abnormal findings, adjusts medications, and schedules follow-up appointments. Documentation happens in real time using the electronic health record system. The PA also fields calls from the triage nurse, making clinical decisions about whether patients should come in urgently, go to the emergency department, or manage symptoms at home.

In a surgical setting, the day looks different. A PA assisting an orthopedic surgeon scrubs into procedures, positions patients, assists with surgical exposure, handles tissue retraction, closes incisions, and manages post-operative patient rounds. O*NET specifies that PAs "provide physicians with assistance during surgery or complicated medical procedures" [3].

Core Responsibilities

Primary duties, consuming approximately 60 percent of clinical time:

1. Conduct patient examinations and assessments by taking comprehensive histories, performing physical examinations, and reviewing prior medical records to establish clinical context.
2. Diagnose medical conditions by interpreting symptoms, physical findings, and diagnostic test results to reach accurate clinical conclusions and differential diagnoses [3].
3. Develop and implement treatment plans that address diagnosed conditions through medication, procedures, referrals, lifestyle modification, and follow-up care.
4. Prescribe medications including controlled substances (with DEA registration), selecting appropriate drugs, dosages, and routes based on patient characteristics and drug interactions.
5. Order and interpret diagnostic tests including laboratory panels, imaging studies (X-rays, CT scans, MRIs), electrocardiograms, and specialized assessments [3].
6. Provide patient education and counseling on diagnoses, treatment options, medication regimens, preventive care, and healthy lifestyle practices [3].

Secondary responsibilities, approximately 30 percent of time:

7. Perform clinical procedures including wound repair (suturing, stapling), incision and drainage, joint injections, splinting, casting, skin biopsies, and minor surgical procedures.
8. Assist in surgery by first-assisting during operations, managing surgical site exposure, suturing, and providing intraoperative monitoring.
9. Manage hospital rounds by visiting inpatients, updating treatment plans, reviewing test results, coordinating with specialists, and preparing discharge plans [3].
10. Refer patients to specialists and coordinate care across multiple providers to ensure continuity and completeness of treatment.

Administrative and leadership activities, approximately 10 percent:

11. Maintain clinical documentation including encounter notes, procedure reports, and referral letters that meet medical-legal and billing standards.
12. Supervise clinical support staff including medical assistants, phlebotomists, and patient care technicians, and order medical and laboratory supplies [3].

Required Qualifications

Physician assistants must hold a master's degree from a PA program accredited by the Accreditation Review Commission on Education for the Physician Assistant (ARC-PA). PA programs are typically 27 months (approximately three years) in duration and include both didactic (classroom) and clinical (rotation) phases [1].

Admission to PA programs requires a bachelor's degree (any major, though science-heavy coursework is expected) and direct patient care experience. Most successful applicants have 2,000 to 4,000 hours of hands-on healthcare experience as EMTs, paramedics, medical assistants, nurses, or military corpsmen. Prerequisite coursework includes anatomy, physiology, microbiology, chemistry, and statistics [4].

Certification through the National Commission on Certification of Physician Assistants (NCCPA) is required for licensure in all 50 states. Candidates must pass the Physician Assistant National Certifying Examination (PANCE), a 300-question multiple-choice exam covering medical knowledge. Certification maintenance requires 100 hours of continuing medical education (CME) every two years and passing the Physician Assistant National Recertifying Examination (PANRE) every ten years [5].

State licensure is mandatory. All states require PAs to be licensed. Most states require a collaborative or supervisory agreement with a physician, though several states have adopted or are considering "Optimal Team Practice" legislation that expands PA practice authority [1].

Additional certifications include Basic Life Support (BLS) and Advanced Cardiovascular Life Support (ACLS) from the American Heart Association. Specialty-specific certifications include Advanced Trauma Life Support (ATLS) for surgical and emergency PAs and Pediatric Advanced Life Support (PALS) for those working with children.

Preferred Qualifications

Specialty experience is the strongest differentiator. Emergency departments prefer PAs with emergency medicine clinical rotations or prior EM experience. Surgical practices prefer PAs with demonstrated first-assist skills and operating room exposure. Dermatology, one of the highest-paying PA specialties, prefers candidates with dermatology-specific fellowships or postgraduate training programs.

PA residency and fellowship programs, while not required, provide intensive post-graduate training in specific specialties (emergency medicine, surgery, orthopedics, dermatology). Completion of these programs accelerates clinical competency and often results in higher starting salaries [2].

Experience with specific EHR systems (Epic is the most common request), telemedicine platforms, and point-of-care ultrasound (POCUS) are increasingly listed as preferred qualifications. Bilingual proficiency, particularly in Spanish, is valued in communities with significant non-English-speaking populations.

Tools and Technologies

Physician assistants use clinical, diagnostic, and administrative technologies throughout each workday:

• Electronic Health Records: Epic Systems (dominant in large health systems), Cerner/Oracle Health, eClinicalWorks, MEDITECH, and athenahealth for smaller practices. EHR proficiency is essential for documentation, order entry, prescription management, and care coordination [3].
• Diagnostic Equipment: Stethoscopes, otoscopes, ophthalmoscopes, dermatoscopes, blood pressure monitors, pulse oximeters, point-of-care ultrasound (POCUS), electrocardiogram machines, and spirometers.
• Clinical Reference Tools: UpToDate for evidence-based clinical decision support, Epocrates and Lexicomp for drug information, MDCalc for clinical calculators, and VisualDx for dermatologic diagnosis support.
• Communication Platforms: Secure messaging (TigerConnect), telemedicine platforms (Teladoc, Amwell, Doxy.me), and dictation software (Dragon Medical, Nuance) for efficient documentation.

Secondary tools include medical coding software (ICD-10, CPT for billing), surgical navigation systems (for orthopedic and neurosurgical PAs), and quality reporting dashboards.

Emerging technologies include AI-powered ambient clinical documentation that listens to patient encounters and generates structured notes, AI-assisted diagnostic imaging interpretation, and remote patient monitoring platforms using connected devices [4].

Work Environment and Schedule

Physician assistants work in physicians' offices, hospitals, outpatient clinics, urgent care centers, surgical centers, and other healthcare settings [1]. The distribution varies: the AAPA reports that approximately 24 percent of PAs work in primary care, 24 percent in surgical subspecialties, and the remainder across emergency medicine, hospital medicine, dermatology, orthopedics, and other specialties [2].

Work schedules vary significantly by setting. Office-based PAs typically work standard weekday hours with occasional Saturday clinics. Hospital-based PAs work rotating shifts including nights, weekends, and holidays, often in 10 or 12-hour shift patterns. Emergency department PAs work a mix of shifts around the clock.

On-call requirements are common, particularly for surgical and hospital medicine PAs. Call may involve phone triage, responding to the hospital for emergencies, or covering weekend rounding.

Physical demands are moderate to high depending on the specialty. Surgical PAs stand for extended periods during operations. Emergency medicine PAs may assist with patient transfers and procedures requiring physical exertion. All PAs face occupational exposure to infectious diseases and must follow universal precautions [1].

Salary Range and Benefits

The Bureau of Labor Statistics reports a median annual wage of $133,260 for physician assistants in May 2024 [1]. The lowest 10 percent earned less than $83,890, while the highest 10 percent earned more than $168,120. The AAPA reports median total compensation (including bonus and overtime) of $134,000 in 2024, a 5.5 percent increase from the prior year [2].

Specialty dramatically affects compensation. Cardiovascular and cardiothoracic surgery PAs earn a median of $158,470, dermatology PAs earn approximately $150,000, emergency medicine PAs earn $141,440, and primary care PAs earn closer to the overall median [2].

Benefits typically include comprehensive health, dental, and vision insurance, malpractice insurance coverage (paid by employer in most settings), retirement plans (403(b) or 401(k)), CME allowances ($2,000 to $5,000 annually plus five to ten CME days), student loan repayment programs (particularly in underserved areas through the National Health Service Corps), paid time off, licensure and certification fee reimbursement, and DEA registration fee coverage.

Career Growth from This Role

Physician assistants advance through clinical specialization, leadership, and administration. Clinical advancement includes Senior PA, Lead PA, and PA Supervisor roles with increasing responsibility for clinical protocols, peer supervision, and quality metrics.

Administrative paths lead to Director of Advanced Practice Providers, Director of Clinical Operations, or Vice President of Medical Affairs. Some PAs transition into hospital administration, healthcare consulting, or health policy roles.

Specialty transitions are a unique advantage of the PA profession. A primary care PA can transition to dermatology, orthopedics, or emergency medicine by completing focused training or post-graduate fellowships without returning to PA school. This flexibility is built into the profession's training model.

Entrepreneurial PAs pursue ownership of urgent care clinics, telemedicine companies, or consulting practices. Academic PAs teach in PA programs, conduct clinical research, or develop continuing education content.

The typical timeline from new graduate PA to lead PA or supervisory role is five to eight years, depending on specialty and organizational structure [1].

FAQ

What is the difference between a physician assistant and a nurse practitioner? PAs are trained in the medical model (disease-focused) and can practice across any specialty without re-certification. NPs are trained in the nursing model (patient-centered, holistic) and must certify in a specific population focus. Both prescribe, diagnose, and treat. Practice authority laws vary by state for both professions.

Can physician assistants practice independently? Practice authority varies by state. Some states have adopted "Optimal Team Practice" legislation that reduces or eliminates mandatory physician supervision requirements. Most states require a collaborative agreement with a physician, though the level of oversight varies [1].

How long does it take to become a physician assistant? The typical path is a four-year bachelor's degree plus a 27-month (approximately three-year) PA program, totaling about seven years. Most programs also require 2,000 to 4,000 hours of direct patient care experience prior to admission [4].

Is PA school harder to get into than medical school? PA program acceptance rates average around 20 to 30 percent, comparable to medical school admissions. The academic prerequisites overlap significantly. PA programs weigh clinical experience more heavily, while medical schools weigh research experience and standardized test scores (MCAT).

What are the highest-paying PA specialties? Cardiovascular surgery ($158,470 median), dermatology ($150,000), emergency medicine ($141,440), and orthopedic surgery are consistently among the highest-paying PA specialties [2].

Can PAs switch specialties? Yes. This is one of the PA profession's defining advantages. PAs can transition between specialties (e.g., from primary care to emergency medicine or surgery) through on-the-job training, postgraduate fellowships, or focused CME. No re-certification in a new specialty is required, though some employers prefer candidates with relevant experience.

What is the job outlook for physician assistants? Excellent. The BLS projects 20 percent growth from 2024 to 2034, much faster than the average for all occupations. Demand is driven by physician shortages, an aging population, and healthcare organizations' increasing reliance on PAs to extend care delivery capacity [1].
