Primary care is the backbone of the healthcare system. It provides comprehensive, accessible care for a wide range of health issues, from preventive screenings and wellness visits to chronic disease management and acute care. But with such a broad scope, primary care billing can be complex.
Billing correctly requires a deep understanding of coding rules, payer policies, and documentation standards. Let’s break down the key components of billing in a primary care setting.
1. Evaluation and Management (E/M) Coding
E/M codes are the most frequently used in primary care billing. Common codes include:
99213 – Office visit for an established patient (low complexity)
99214 – Office visit for an established patient (moderate complexity)
As of the 2021 updates, providers can choose E/M levels based on time spent on the day of service or medical decision-making (MDM). Accurate documentation of either method is essential.
2. Preventive Visits vs. Problem-Oriented Visits
Preventive care visits (e.g., 99395 for an established adult patient) focus on screenings, immunizations, and risk factor counseling. These are often covered annually with no patient cost-sharing.
However, if a patient brings up an acute or chronic issue during a preventive exam, that portion may be separately billable as an E/M visit — provided documentation supports it. In such cases, a modifier -25 should be added.
3. Annual Wellness Visits (AWVs) for Medicare Patients
Medicare covers specific wellness visits:
G0402 – Initial preventive physical exam (IPPE)
G0438 – First annual wellness visit
G0439 – Subsequent annual wellness visit
These visits must follow CMS guidelines and do not include a full physical exam. Misunderstanding this distinction can lead to billing errors or denials.
4. Immunization Billing
Vaccines must be billed using:
A product code (e.g., 90658 for flu vaccine)
An administration code (e.g., 90471 for the first vaccine, 90472 for each additional one)
Proper documentation should include the vaccine name, lot number, and administration site.
5. Chronic Care Management (CCM)
CCM services allow providers to bill for managing two or more chronic conditions outside face-to-face visits. CPT codes like 99490 (20+ minutes per month) and 99439 (each additional 20 minutes) can be used with patient consent and thorough time tracking.
6. Telehealth Considerations
Telehealth visits surged during the COVID-19 pandemic and continue to be a vital part of primary care. Providers can bill standard E/M codes for these visits, but must include:
Correct Place of Service (POS) codes: 02 or 10
Modifier -95 for synchronous, real-time communication
Coverage policies vary by payer, so it’s essential to verify telehealth-specific rules.
7. Screenings and Counseling Services
Primary care providers offer multiple screenings, which are separately billable:
G0444 – Annual depression screening
G0442 – Alcohol misuse screening
99406 / 99407 – Smoking cessation counseling
These services should be documented as distinct and medically necessary.
8. Importance of Accurate Documentation
The key to successful billing lies in thorough documentation. Each billed service should be clearly supported by:
Medical necessity
Time spent (if applicable)
Details of exam, findings, assessments, and plans
Incomplete or vague notes can lead to audits, downcoding, or payment delays.
Conclusion
Primary care billing is multifaceted, involving multiple services and payer-specific requirements. By understanding core billing elements—like E/M coding, preventive visit rules, chronic care, and telehealth guidelines—practices can minimize errors, comply with payer policies, and ensure accurate reimbursement.
A consistent, detail-oriented billing process helps primary care providers focus on what matters most: delivering high-quality, patient-centered care.
