A primary care physician is the doctor who manages your overall health year after year. The job has four parts. Your PCP provides preventive care such as physicals, screenings, and vaccines. They manage long term conditions like diabetes, high blood pressure, and high cholesterol. They diagnose and treat everyday illness and injury. And they coordinate the rest of your care, referring you to specialists and folding those results back into one record.

Your primary care doctor is the only clinician looking at your whole health picture instead of one organ or one problem. Here is what that work looks like in practice.

What Does a Primary Care Physician Do at a Typical Visit?

A primary care visit is tailored to your individual health needs. During an annual physical, your provider may check your blood pressure, review medications, discuss recommended screenings and vaccines, order lab work, and address any health concerns you may have. If additional care is needed, your provider can also recommend testing or refer you to a specialist.

A 2022 study in the Journal of General Internal Medicine measured the load. Researchers from the University of Chicago, Johns Hopkins University, and Imperial College London found that following national guidelines for a panel of 2,500 adults would take 26.7 hours per day. With a care team sharing the work, that drops to 9.3 hours.

Part of the job	Hours per day alone	Hours per day with a team
Preventive care	14.1	2.0
Chronic disease care	7.2	3.6
Acute illness care	2.2	1.1
Notes and messages	3.2	2.6
Total	26.7	9.3

Why One Doctor Handles So Many Different Problems

Primary care is built for breadth. The same practice that treats your child’s ear infection manages your father’s heart failure. At Yorktown Health Vernon Hills, that range runs from well child exams through senior care.

Despite that reach, the Milbank Memorial Fund reported in its 2025 Primary Care Scorecard that primary care receives under 5 percent of total U.S. health care spending.

When Your PCP Sends You to a Specialist

A referral is not a handoff. Your primary care doctor picks the specialist, shares your history, and reviews the results so the plan fits your other conditions and medications.

Final Thoughts

A primary care physician helps you stay healthy through preventive care, treats illnesses when they arise, manages ongoing health conditions, and coordinates care when a specialist is needed. Having a consistent primary care provider also makes it easier to track changes in your health over time.
