Primary care practices form the front line of healthcare delivery, providing a broad spectrum of services — from preventive care and routine screenings to chronic disease management and urgent concerns. With this diversity comes billing complexity that requires careful attention to detail, accurate coding, and a clear understanding of payer policies.
This guide explores the essentials of primary care billing, helping you understand key components, coding practices, and common challenges.
What Makes Primary Care Billing Unique?
Unlike specialty practices focused on specific areas, primary care covers:
-
Preventive care (annual check-ups, immunizations)
-
Acute care (infections, injuries)
-
Chronic care (diabetes, hypertension)
-
Screenings and counseling
-
Minor procedures
Because these services are often delivered in a single visit, billing must accurately reflect each component — sometimes with multiple codes and modifiers.
Core Components of Primary Care Billing
1. Evaluation and Management (E/M) Services
E/M codes (e.g., 99213, 99214) are central to primary care billing. Since 2021, providers may select codes based on:
Proper documentation is crucial. It should include the time spent (if applicable), patient history, clinical findings, and the plan of care.
2. Preventive Services
Preventive visits are coded separately from problem-oriented visits. Common codes include:
Preventive visits include screenings and risk assessments but exclude physical exams in Medicare AWVs — a common source of confusion and denials.
3. Vaccinations and Immunizations
Billing for vaccines requires:
-
A product code (e.g., 90686 for flu shot)
-
An administration code (e.g., 90471 for the first vaccine, 90472 for each additional)
Payers often require documentation of vaccine lot number, site, and informed consent.
4. Chronic Care Management (CCM)
For patients with two or more chronic conditions, primary care providers can bill for non-face-to-face care coordination. Examples include:
CCM services must be tracked and documented in detail. Verbal or written patient consent is also required.
5. Same-Day Problem & Preventive Visits
If a patient is scheduled for a preventive visit but also addresses an acute or chronic issue, both can be billed. This requires:
Common Billing Challenges in Primary Care
🔹 Payer Variability
Coverage and documentation requirements for preventive care, screenings, and telehealth differ widely across payers. Always verify policies and reimbursement rules.
🔹 Incomplete Documentation
Missing details on time spent, decision-making, or patient consent can lead to denials or downcoding.
🔹 Coding for Screenings and Counseling
Services like depression screening (G0444) or smoking cessation counseling (99406) are billable but often missed or bundled without proper coding.
🔹 Telehealth Coding
E/M visits via telehealth use standard codes (e.g., 99213) but require:
Reimbursement rules vary by payer, especially for audio-only services.
Best Practices for Accurate Billing
-
Use updated coding guidelines for E/M services
-
Confirm payer-specific billing policies regularly
-
Ensure complete and clear documentation
-
Track non-face-to-face time for CCM and care coordination
-
Train staff on modifier usage and preventive vs. diagnostic coding
Conclusion
Primary care billing is both broad and nuanced. By understanding the different types of visits, following proper documentation practices, and staying informed about payer policies, primary care teams can reduce denials, maximize reimbursement, and improve efficiency across the revenue cycle.
Accurate billing supports not only financial stability — it also ensures patients receive the full range of services they’re entitled to.
