What Is a Primary Care Physician (PCP)?

A primary care physician (PCP) is a doctor who serves as your first point of contact for most non-emergency health concerns. PCPs provide preventive care (annual physicals, vaccines, screenings), diagnose and treat common illnesses, manage chronic conditions like diabetes and hypertension, refer you to specialists when needed, and coordinate your overall care. Common PCP types include family medicine (treats all ages), internal medicine (adults only), pediatrics (children only), and geriatrics (older adults). Most US adults benefit from having an established PCP.

How to Choose a PCP

  1. Confirm insurance acceptance. Verify they take your specific plan and are accepting new patients. See how to find a doctor that takes Medicare if applicable.
  2. Check verification. Look them up on The Doctor Directory for verified profile and license status.
  3. Check board certification. Verify at certificationmatters.org that they are board-certified in Family Medicine, Internal Medicine, or Pediatrics.
  4. Consider practice logistics. Distance from home or work, evening/weekend hours, portal access, telehealth availability.
  5. Read patient reviews. Focus on communication style, wait times, and staff responsiveness rather than raw scores.
  6. Ask about sick-visit access. Some practices route same-day sick issues to urgent care; others handle them in-house.
  7. Meet them first if uncertain. A get-acquainted visit is a normal request. If a practice will not accommodate it, that itself is information.

What is the difference between family medicine and internal medicine?

Family medicine doctors treat patients of all ages from newborns to seniors, and often deliver babies and handle basic OB-GYN care. Internal medicine doctors treat adults only (18+) and typically have deeper training in complex adult chronic disease. Both are primary care specialties.

How do I choose a primary care doctor?

Choose a PCP by: confirming insurance and new-patient status, checking board certification, considering location and hours, reading reviews for communication style, asking whether they handle same-day sick visits, and meeting them for a get-acquainted visit if uncertain.
