Primary Care: What a PCP Treats and When to See One

What Primary Care Is

Primary care is defined by the American Academy of Family Physicians (AAFP) as "the provision of integrated, accessible health care services by physicians and their health care teams who are accountable for addressing a large majority of personal health care needs" 1Ref 1American Academy of Family Physicians (AAFP) (2024).Primary Care (Policy Statement).AAFP definition of primary care; the three recognized disciplines (family medicine, general internal medicine, general pediatrics); and the scope across any undiagnosed sign/symptom, organ system, or origin, delivered across settings including office, inpatient, home, and telehealth. The three recognized primary care disciplines are family medicine, general internal medicine, and general pediatrics 1Ref 1American Academy of Family Physicians (AAFP) (2024).Primary Care (Policy Statement).AAFP definition of primary care; the three recognized disciplines (family medicine, general internal medicine, general pediatrics); and the scope across any undiagnosed sign/symptom, organ system, or origin, delivered across settings including office, inpatient, home, and telehealth.

A primary care physician is the clinician a person sees for most health concerns — new or ongoing — before a specialist referral if needed. The AAFP's definition covers patients with any "undiagnosed sign, symptom, or health concern," regardless of organ system or whether the origin is physical, behavioral, or social 1Ref 1American Academy of Family Physicians (AAFP) (2024).Primary Care (Policy Statement).AAFP definition of primary care; the three recognized disciplines (family medicine, general internal medicine, general pediatrics); and the scope across any undiagnosed sign/symptom, organ system, or origin, delivered across settings including office, inpatient, home, and telehealth. Settings include outpatient offices, telehealth, hospitals, nursing facilities, and home visits.

Conditions a PCP Treats

Primary care physicians manage a broad, intentionally unspecialized scope. Common categories include:

Acute illnesses - Ear infections (otitis media and otitis externa) - Urinary tract infections — uncomplicated lower UTIs are frequently managed by a PCP without specialist referral - Sore throat and strep pharyngitis — only about 10% of adults with a sore throat have group A streptococcal infection, yet more than 60% receive antibiotics; a PCP uses validated decision tools (Centor criteria) to avoid unnecessary prescribing 3Ref 3Hamilton JL, McCrea L (2024).Streptococcal Pharyngitis: Rapid Evidence Review.Only 10% of adults with sore throat have group A streptococcal infection; 60%+ are prescribed antibiotics; use of clinical decision tools (Centor) and rapid antigen testing to avoid overtreatment; first-line treatment is penicillin or amoxicillin - Sinusitis, upper respiratory infections, influenza, pink eye, minor skin infections

Chronic disease management - Hypertension, high cholesterol, type 2 diabetes - Depression and anxiety — PCPs screen for and often initiate treatment of common mental health conditions - Obesity and weight management, including GLP-1 receptor agonist medications for eligible patients (see the GLP-1 section below) - Asthma, COPD, thyroid disorders

Preventive and screening services MedlinePlus / NIH lists preventive services typically delivered in primary care: blood pressure monitoring, blood sugar testing, cholesterol screening, colorectal cancer screening, depression screening, breast and cervical cancer screening, lung cancer screening for high-risk smokers, STI testing, and immunization updates 2Ref 2Vorvick LJ; A.D.A.M. Editorial Team (2025).Preventive health care.Preventive services delivered in primary care: blood pressure, blood sugar, cholesterol, cancer screenings (colorectal, breast, cervical, lung), depression screening, STI testing, and immunizations.

Care coordination When a condition exceeds primary care scope, a PCP refers to the appropriate specialist and integrates those recommendations into a unified care plan — particularly important for patients managing multiple chronic conditions.

Primary Care vs. Urgent Care vs. the ER

These three settings serve different needs and carry different costs.

Primary care is the right setting for ongoing relationships, preventive visits, chronic disease management, and most acute non-emergency illnesses. A PCP who knows a patient's history makes safer prescribing decisions and catches trends over time.

Urgent care is appropriate for acute issues that need same-day attention but are not life-threatening — a sprain, a possible UTI when the PCP is unavailable, or a minor laceration. Costs are typically higher than primary care but lower than the ER.

Emergency departments (EDs) are for true emergencies: chest pain, difficulty breathing, stroke symptoms, severe abdominal pain, major trauma, or altered mental status. Using the ED for non-emergency conditions is significantly more expensive and diverts resources from people with life-threatening conditions.

For many acute primary care conditions — UTIs, sore throats, ear infections, cold and flu symptoms, rashes, depression follow-up — a telehealth visit with a primary care clinician is an appropriate and often faster option (see below).

Telehealth Primary Care: What Can Be Handled Remotely

Telehealth has become a standard delivery channel for primary care. A 2022 systematic review found that 89% of studies confirmed chronic condition management, medication management, and follow-up care as appropriate for telehealth visits 5Ref 5Ward MM, Vagholkar S, Sakur F, Khatri RB, Lau A (2022).Visit Types in Primary Care With Telehealth Use During the COVID-19 Pandemic: Systematic Review.Systematic review of 19 studies: chronic condition management, medication management, and follow-up care used telehealth in 89% of studies; benefits include improved convenience and continuity of care; limitations include physical exam accuracy. A 2025 scoping review of 170 studies concluded that virtual care is equivalent to in-person care for counseling and appropriate for many acute primary care conditions 6Ref 6Agarwal P, Fletcher GG, Ramamoorthi K, Yao X, Bhattacharyya O (2025).Uses of Virtual Care in Primary Care: Scoping Review.170-study scoping review: virtual care equivalent to in-person care for counseling; appropriate for many acute and chronic primary care conditions; virtual triage reduces unnecessary in-person visits.

Conditions well-suited to telehealth: - Uncomplicated UTI symptoms in adult women - Sore throat evaluation (Centor criteria-based) - Medication refills and chronic disease follow-up (blood pressure, diabetes, mental health) - Skin rash photo assessment; cold and flu symptom management - GLP-1 medication initiation and weight management monitoring

When in-person care is needed: Conditions requiring a physical exam, imaging, in-office labs (throat culture, blood draw), or a procedure cannot be fully managed remotely.

For UTI: a 2025 VA cohort study of 45,562 visits found no significant overall difference in clinical failure rates between telehealth and in-person primary care (adjusted RR 0.87), though elderly patients may benefit from in-person culture-guided care 4Ref 4Madaras-Kelly KJ, Boyd JK, Bond L (2025).The comparative effectiveness of telehealth versus primary care and collection of urine cultures on outcome in urinary tract infection.45,562-visit VA cohort study: adjusted relative risk of clinical failure for telehealth vs. in-person primary care for UTI was 0.87 (95% CI 0.70–1.08) — no significant overall difference; elderly patients ≥65 showed higher telehealth failure rates.

Seeing a Doctor Without Insurance

The AAMC projects a shortage of up to 86,000 physicians by 2036, with the 65+ population growing 34% — increasing demand as supply declines 7Ref 7Association of American Medical Colleges (AAMC) (2024).New AAMC Report Shows Continuing Projected Physician Shortage.Projected shortage of up to 86,000 physicians by 2036; population aged 65+ projected to grow 34.1% — driving increased demand while physician workforce ages out; context for access barriers. For those without insurance, access requires knowing the right channels.

Federally Qualified Health Centers (FQHCs): By law, FQHCs cannot turn patients away for inability to pay. They use a sliding-fee discount program tied to the Federal Poverty Guidelines — patients at or below 100% pay a full discount or only a nominal charge; those between 100% and 200% pay a partial, reduced amount; and there are no discounts above 200% 9Ref 9Health Resources and Services Administration (HRSA), Bureau of Primary Health Care (2024).Health Center Program Compliance Manual, Chapter 9: Sliding Fee Discount Program.HRSA requires Health Center Program grantees (FQHCs) to operate a Sliding Fee Discount Program so no patient is denied services due to inability to pay: a full discount or only a nominal charge at or below 100% of the Federal Poverty Guidelines, partial discounts between 100% and 200% FPG, and no discounts above 200% FPG.

Telehealth cash-pay platforms: Primary care visits range from approximately $30–$99 without insurance. Many platforms can prescribe antibiotics, renew maintenance medications, and handle straightforward acute conditions. Generic prescriptions often cost $4–$20 with discount programs at major pharmacy chains.

Direct Primary Care (DPC): DPC practices charge patients a flat periodic membership fee — typically monthly, quarterly, or annual — directly for primary care, as an alternative to fee-for-service insurance billing 10Ref 10American Academy of Family Physicians (AAFP) (2024).Direct Primary Care.AAFP describes Direct Primary Care as an alternative to fee-for-service insurance billing in which the practice charges patients a flat periodic fee (monthly, quarterly, or annual) directly for primary care services. Monthly fees commonly fall in the low hundreds of dollars or less, though amounts vary by practice, location, and age.

GLP-1 Medications: A Growing Primary Care Role

Primary care physicians have become key prescribers of GLP-1 receptor agonist medications for chronic weight management. KFF polling in May 2024 found that 6% of U.S. adults reported currently taking a GLP-1 drug, and 12% reported having ever taken one 8Ref 8Montero A, Sparks G, Presiado M, Hamel L (KFF) (2024).KFF Health Tracking Poll May 2024: The Public's Use and Views of GLP-1 Drugs.National KFF Health Tracking Poll fielded May 2024: 6% of U.S. adults say they are currently taking a GLP-1 drug, and about one in eight (12%) say they have ever taken one.

The FDA approves Zepbound (tirzepatide), alongside Wegovy (semaglutide), for chronic weight management in adults with a BMI of 30 or above, or 27 or above with at least one weight-related condition such as hypertension, type 2 diabetes, dyslipidemia, or obstructive sleep apnea 11Ref 11U.S. Food and Drug Administration (FDA) (2023).FDA Approves New Medication for Chronic Weight Management.FDA approved Zepbound (tirzepatide) for chronic weight management in adults with obesity (BMI 30 or greater) or overweight (BMI 27 or greater) with at least one weight-related condition (e.g., hypertension, type 2 diabetes, dyslipidemia), used with reduced-calorie diet and increased physical activity. A PCP evaluates eligibility, screens for contraindications, and manages the dose-escalation schedule over time.

Primary care is also the right setting to address the muscle-loss concern associated with GLP-1 use — a PCP can counsel on protein intake and resistance training to preserve lean mass, and refer to a dietitian or exercise specialist when needed.

What to Expect at a Primary Care Visit

New patient visit (45–60 minutes): Comprehensive history, medication review, vital signs, age- and sex-appropriate physical exam, baseline lab or screening orders, and care plan.

Acute visit (15–30 minutes): Focused evaluation of a single complaint — ear pain, dysuria, sore throat — with diagnosis, treatment, and escalation criteria if symptoms worsen.

Annual wellness visit: Preventive screening review aligned with USPSTF recommendations, immunization update, depression screening, and chronic disease check-in 2Ref 2Vorvick LJ; A.D.A.M. Editorial Team (2025).Preventive health care.Preventive services delivered in primary care: blood pressure, blood sugar, cholesterol, cancer screenings (colorectal, breast, cervical, lung), depression screening, STI testing, and immunizations.

Telehealth visit: Symptom questionnaire plus video or phone consultation. For appropriate conditions, the clinician can prescribe to a local pharmacy, order labs at a nearby draw site, or generate a specialist referral — all without an in-person visit 5Ref 5Ward MM, Vagholkar S, Sakur F, Khatri RB, Lau A (2022).Visit Types in Primary Care With Telehealth Use During the COVID-19 Pandemic: Systematic Review.Systematic review of 19 studies: chronic condition management, medication management, and follow-up care used telehealth in 89% of studies; benefits include improved convenience and continuity of care; limitations include physical exam accuracy6Ref 6Agarwal P, Fletcher GG, Ramamoorthi K, Yao X, Bhattacharyya O (2025).Uses of Virtual Care in Primary Care: Scoping Review.170-study scoping review: virtual care equivalent to in-person care for counseling; appropriate for many acute and chronic primary care conditions; virtual triage reduces unnecessary in-person visits.

Preparation tips: Bring a current medication list, note any allergies, and state the main concern at the start of the visit to help the clinician use the available time most effectively.
