Understanding Physician Assistant Billing
Physician assistants perform many vital services under physician supervision. Billing for these services requires adherence to specific regulations. Two common models used are direct billing and “incident to” billing.
- Direct Billing: Under this model, claims are submitted using the physician assistant’s National Provider Identifier (NPI). Reimbursement is set at 85% of the physician's fee schedule rate.
- “Incident To” Billing: This method allows claims to be billed under the supervising physician’s NPI. Reimbursement is 100% of the physician’s rate. However, strict rules must be followed. These include the physician being present in the office suite when the service is provided.
Failing to understand these models often results in claim denials. To manage these complexities, many healthcare providers use a Medical Billing Virtual Assistant or remote medical biller.
Mistake 1: Misinterpreting “Incident To” Billing Rules
“Incident to” billing is one of the most misunderstood aspects of physician assistant billing. The supervising physician must have already established the care plan for the patient. They must also be present in the office suite during the service. If these requirements are not met, the claim will be denied.
Solution
Educate billing staff to ensure they understand “incident to” billing requirements. Use a virtual assistant medical billing professional to review claims before submission. This prevents non-compliance and improves reimbursement rates.
Mistake 2: Incorrect Use of Modifier Codes
Modifier codes are used to explain specific circumstances related to a claim. Failing to use the correct modifiers is a common error in physician assistant billing. For example, the -AS modifier must be used when a PA assists in surgery. Omitting this modifier can lead to denials.
Solution
Train your coding staff on the proper use of modifier codes. Employing a billing assistant or medical billing assistant with coding expertise reduces these errors.
Mistake 3: Billing for Non-Covered Services
Not all services provided by physician assistants are covered by Medicare or private insurers. Examples include administrative tasks or services outside the PA’s scope of practice. Billing for these services leads to claim rejections.
Solution
Review payer-specific guidelines before submitting claims. A Medical Billing Virtual Assistant with experience in payer rules ensures claims include only covered services.
Data Insight
In 2022, CMS reported that 15% of Medicare claim denials occurred due to non-covered services. This statistic highlights the importance of verifying service eligibility before submitting claims.

Incomplete or unclear documentation is a significant cause of claim denials. Accurate documentation is essential for demonstrating medical necessity and meeting payer requirements.
Solution
Train PAs to provide comprehensive documentation for every service. Conduct routine internal audits to ensure compliance with documentation standards. Engage a remote medical biller to review claims and address any documentation gaps.
Mistake 5: Misunderstanding Shared and Split Services
Shared or split services occur when both a physician and a PA provide care during the same visit. Errors in billing these services occur when the wrong provider is assigned as the primary. This leads to claim rejections or audits.
Solution
Train billing staff on the rules for shared and split services. Assign a medical billing assistant to oversee claims involving shared services. Proper documentation of who provided the substantive portion of care ensures compliance.
Mistake 6: Failing to Stay Updated on Policy Changes
Policies for physician assistant billing change frequently. For example, telehealth billing rules have expanded, allowing PAs to bill for more remote services. Practices that fail to keep up with these updates risk billing incorrectly.
Solution
Stay informed about policy updates through newsletters and webinars. Provide ongoing training for your billing team. Employing a virtual assistant medical billing expert ensures these updates are incorporated into billing practices.
Mistake 7: Overlooking VA Billing Requirements
Billing for services provided through the Veterans Affairs (VA) healthcare system has unique requirements. Failing to follow VA-specific billing rules can lead to claim denials.
Solution
Work with professionals experienced in VA medical billing. A Medical Billing Virtual Assistant familiar with these requirements can streamline the process. Their expertise ensures compliance with VA policies.
Role of Technology in Avoiding Errors
Technology helps reduce errors in physician assistant billing. Billing software with built-in compliance tools flags potential errors before claims are submitted. Professionals like a remote medical biller use these tools to ensure accuracy.
Benefits of Technology
- Automated checks for coding errors
- Real-time updates on payer requirements
- Simplified claim tracking
Human oversight remains essential, even with technology. Certified billing professionals such as a medical billing assistant provide the expertise needed for interpreting complex guidelines.
Future Trends in Physician Assistant Billing
The field of physician assistant billing is evolving. Professionals must adapt to new billing rules and technological advancements. Key trends include:
- AI in Billing: Artificial intelligence is expected to improve claim processing and reduce errors.
- Telehealth Expansion: The demand for billing telehealth services provided by PAs will continue to grow.
- Remote Billing Professionals: More practices will hire remote medical billers to manage complex billing processes.
Industry Growth
A report from the American Health Information Management Association shows a 25% increase in demand for certified billing professionals since 2020. This reflects the rising complexity of healthcare billing systems.
Conclusion
Avoiding mistakes in physician assistant billing is crucial for compliance and timely reimbursements. Common errors include misunderstanding “incident to” billing, using incorrect modifiers, and submitting claims for non-covered services. Hiring skilled professionals like a Medical Billing Virtual Assistant or billing assistant can address these challenges.
Regular training, thorough documentation, and the use of technology are vital for reducing errors. Staying informed about changes in billing regulations ensures healthcare providers remain compliant. By addressing these mistakes proactively, practices can maintain efficient billing processes and focus on delivering quality patient care.
