What is a primary care provider?
Primary care handles most everyday health needs: preventive care, new symptoms, chronic disease management and coordination with other services. The PCP is the clinician responsible for that ongoing relationship with the patient. Many patients never formally name a PCP, so health plans and value-based programs often attribute each patient to one based on claims history.
Definitions differ by program. Some count only physicians in family medicine, general internal medicine and general pediatrics. Others add obstetrics and gynecology, geriatrics, and nurse practitioners and physician assistants who practice in primary care.
Who counts as a PCP
Depending on the definition, PCPs include:
- Family medicine physicians, who treat patients of all ages.
- General internal medicine physicians, who focus on adults.
- General pediatricians, who focus on children and adolescents.
- Obstetrician-gynecologists, in some health plan and federal definitions.
- Nurse practitioners and physician assistants working in primary care settings.
How PCPs are used in coverage and payment
Many HMOs and Medicaid managed care plans require members to choose a PCP, who may need to issue a referral before a specialist visit. Accountable care organizations in the Medicare Shared Savings Program have beneficiaries assigned largely based on where they receive primary care services.
The Health Resources and Services Administration (HRSA) uses counts of primary care physicians relative to population, along with other need factors, to designate primary care Health Professional Shortage Areas (HPSAs).
Why PCPs matter
PCPs are the entry point for many diagnoses and long-term prescriptions, so they drive volume for drugs used in diabetes, hypertension, high cholesterol, respiratory disease and depression. For payers, PCP supply is a core network adequacy measure. For health systems, PCP relationships feed specialist referrals and hospital admissions. For policy analysts, PCP shortages mark gaps in access to care.
