Physician assistants (PAs), soon to known as physician associates and advanced practice registered nurses (APRNs), like nurse practitioners (NPs), midwives, CRNAs, and clinical nurse specialists, have been around for decades. The first class of PAs graduated from Duke University in 1967, and in 1965, the first training program for NPs began at the University of Colorado. Since then, for many reasons, both professions have become integral to the quality delivery of healthcare. Although they have different education, training, and scope (PAs trained in medicine and APRNs in an advanced theory of nursing practice model) integrating these professionals into a practice can elevate the patient experience, as their access to the healthcare services they need will increase, and there could be an increase to the bottom-line financials of a practice as a result. Physicians experience greater job satisfaction, as PA and APRN integration helps to alleviate overburdened work schedules, including on-call obligations. Through these benefits, interprofessional integration leads to better patient retention, patient referrals, physician satisfaction, and stronger financial health for practices and health systems.
The Centers for Medicare & Medicaid Services (CMS) certainly plays a role in the practice and reimbursement environment of PAs and APRNs; however, most of the legislative and regulatory environment for practice is determined at the state level. Due to the evolution of each profession and the historical and ongoing shortage of physicians, it’s important for health systems and practices to stay abreast of primary source legislative and regulatory guidance changes regarding scope, documentation, and billing compliance. These factors are also important to ensure an employer is capturing maximum reimbursement for clinical work done by both professions while minimizing their risk of an audit and resulting penalties. Systems and practices must uphold an ongoing, longitudinal review of Medical Staff Bylaws, delineation of privileges, policies, and processes.
Mastering Billing and Coding
CMS recognizes qualified billing providers to render services independently and establishes billing and coding rules for PAs and APRNs to ensure accurate reimbursement and quality care delivery within the Medicare program. These rules outline the scope of practice and reimbursement guidelines for nurse practitioners, physician assistants, certified nurse-midwives, clinical nurse specialists, and certified registered nurse anesthetists who must adhere to specific documentation requirements, including maintaining accurate patient records and submitting claims using appropriate evaluation and management (E/M) codes, like physicians. Additionally, CMS provides guidance on incident-to billing, which allows certain services provided by PAs and APRNs to be billed under a supervising physician’s National Provider Identifier (NPI). Understanding and following CMS billing and coding rules are essential to navigate the complexities of reimbursement and ensure compliance with Medicare regulations.
Because CMS recognizes PAs and APRNs as qualified billing providers but not as physicians, they fall into a separate reimbursement category. When billing under their own NPI, the reimbursement level is less than what it would be if the physician were to bill for the same services. This reimbursement differential does not adversely impact a practice’s bottom line, as remuneration for a PA or APRN is less than a physician and malpractice cost is less.
Physicians may bill for a service that was rendered by a PA or APRN with incident-to services and with split/shared E/M services. VMG Health Managing Director and coding and compliance expert Pam D’Apuzzo says, “There’s two rules, which is where everybody gets themselves into trouble… Those two rules have specific guidelines, both from a documentation and a billing standpoint. The patient type, the service type—everything needs to be adhered to.”
To bill for incident-to and split/shared E/M services, practices must meet specific criteria outlined by Medicare. For incident-to services, the criteria include:
- The service must be an integral part of the physician’s professional service.
- The service must be performed under the physician’s direct (licensure) supervision.
- The physician must be physically present in the office suite and immediately available to provide assistance if needed.
- The services must be provided by qualified personnel, such as nurse practitioners or PAs, who are employees of the physician or the practice.
For split/shared E/M services, the criteria include:
- The service must be provided by a physician and a qualified PA or APRN during the same visit.
- The service must meet the requirements for both the physician and the PA/APRN to bill their respective service components.
- The documentation must clearly indicate the contributions of both the physician and the PA/APRN to the service provided.
These criteria ensure that incident-to and split/shared services are billed appropriately and in compliance with Medicare guidelines. Medicare also dictates that the “substantive portion” of a split or shared visit is more than half of the time a physician or non-physician practitioner spends performing the visit or a “substantive part” of the medical decision making. Practices must continually educate and train all medical staff so that they can successfully adhere to these criteria to avoid billing errors and potential audits. Additionally, practices must continuously monitor to ensure all documentation, billing, and coding processes are followed correctly.
Risk Reduction
There are tools and services that allow for easier monitoring. “We utilize a tool called Compliance Risk Analyzer, which provides us with statistical insight on coding practices,” D’Apuzzo says. “So, we can data mine ourselves and see what’s happening just based on our views. And this is what the payers, specifically, and the government does as well: They can see the [relative value units] RVUs are for a physician or off the chart, or that a physician has submitted claims for two distinct services at two different locations on the same day.”
This is more common than you might think.
“What’s normally happening in those interactions is that [a physician with two locations] realizes he can’t keep up with all of that patient flow in two places, so they hire a PA and put them at location number two,” D’Apuzzo says. “But now all that billing goes under the physician, so it flags for Medicare.”
With VMG Health’s Compliance Risk Analyzer® (CRA), practices can see the same data mining and areas of risk, as the program would flag the RVUs as a potential audit risk. This gives practices the opportunity to self-audit and refine their processes to ensure they are billing and coding appropriately.
VMG Health offers multiple comprehensive services that help health systems and practices implement and follow new procedures and new provider utilization without issue, from honoring existing care models to ensuring provider compensation is fair, compliant, and reasonable.
Cordell Mack, VMG Health Managing Director, says, “We’ve spent a lot of time trying to make sure we get that right, both in terms of the underlying, practice-level agreements as well as the ways in which the compensation model works for both the physicians and the PAs and APRNs.”
Practice Earnings and Patient Enjoyment
In many practices, physicians struggle to handle their case load, which means their busy schedules can prevent them from seeing existing patients and from taking on new patients. Bringing PAs and APRNs into the fold allows physicians to create capacity in their schedules so that they can see new patients.
BSM Consulting (a division of VMG Health) Senior Consultant and subject matter expert Elizabeth Monroe provides an excellent example: “Let’s say we have an orthopedic surgeon who really wants to spend most of their time in surgery. We would want to have that physician in surgery because that’s what their skill set, and licensure permits. With a nurse practitioner or physician assistant providing follow-up, post-operative care, that oftentimes is a much better model. It allows the physician to do the surgical cases only they can do, but it also eases patient access to care.”
This realignment of a physician’s schedule creates an opportunity to provide more patient services, which easily translates to improved patient satisfaction when, without this, they would likely be unable to see their provider when they felt they needed to be seen. While PA and APRN–rendered Medicare services are reimbursed at 85% instead of 100%, our experts say that the 15% differential shouldn’t dissuade practices and health systems from leveraging the integration.
“It’s a very short-sighted approach to just think about, ‘But we could be making 100% instead of 85% if we bill under the doctor,’ because ultimately, we are never able to do that 100% of the time, and it’s a higher risk than it is reward,” says D’Apuzzo.
Additionally, physicians with packed schedules and no other scheduling options may inadvertently rush through appointments to see each patient scheduled for that day. Patients who feel rushed may leave an appointment feeling unheard and like their problem is unresolved. Additionally, when a patient calls and asks for services but can’t be seen for multiple weeks or months, they may never make an appointment and instead turn to another provider for help.
All of this culminates in poor patient retention, which equals a loss of revenue for the practice. Dissatisfied patients will seek treatment elsewhere. However, when practices and health systems embrace an interprofessional team, patients are more likely to be able to schedule appointments when they feel they need to be seen, feel heard in an appointment and even spend less time in the office overall as they are not impacted by OR cases running late, and so on.
“Practices are better able to meet patient demand, and they’re able to really allow physician assistants, nurses… to add a tremendous value for the patients, offering them outstanding care,” Monroe says.
Strategic Rollout
With both patient demand and physician scarcity placing the U.S. health system in crisis, many practices and health systems know they need to integrate PAs and APRNs into their workflows, but they don’t know how. VMG Health offers strategic advisory services that can guide this implementation to ensure practices are educated, compliant, and working within the care model they prefer.
“Our team would want to spend time really trying to identify the underlying care model that practices are trying to, you know, work inside of,” says Mack.
One approach is to assess patient needs and practice capabilities to determine the most effective roles for PAs and APRNS, such as providing primary care, specialty care, or supporting services like telemedicine. Implementing policies and workflows can ensure efficient PA and APRN utilization while maintaining quality and safety standards.
Finally, ongoing training, quality monitoring are essential to ensure their interprofessional integration into the practice or health system effectively meets patient needs, and care provided by PAs and NPs should be included into physician quality and compliance review processes.
“It starts with getting your appropriate documentation in place… [with] supervisory responsibilities and collaborating physician agreements,” says Mack. “It migrates to, ‘What’s the operational agreement among the team?’ and how cases are presented, or how the physician is consulted. So, it’s getting an underlying clinical service agreement among those professionals.”
Optimal PA and APRN utilization shows up in the numbers. When practices increase patient access to care without overburdening physicians, they can accommodate more patients, leading to increased revenue generation. Moreover, because PAs and APRNs often bill at a lower rate than physicians, integrating them efficiently can improve cost-effectiveness, thereby enhancing the overall financial performance of the practice.
“It should realize an ROI, and that ROI should be something more in terms of duties and tasks that other teammates can’t do,” says Mack. “Meaning, it would be unfortunate if a qualified healthcare professional is working at such a capacity whereby duties some of the day-to-day responsibilities should probably be done by teammates working at a higher level of their own individual license.”
Physician Engagement
Changing existing workflows can be difficult, but the rewards heavily outweigh the risks. Physicians must support interprofessional integration to successfully navigate the transition. Physicians are typically the leaders and decision-makers within medical practices, and their support is essential for implementing any significant changes in workflow or care delivery models, which includes having front office staff, medical assistants, nursing and administrative staff rely and respect the roles of PAs and APRNs. Without physician buy-in, resistance to change may arise, hindering smooth integration and retention.
Physicians play a vital role in collaborating and ensuring a seamless care model is implemented and sustained. By endorsing and supporting the integration of PAs and APRNS, physicians can foster a culture of teamwork and mutual respect within the practice. This collaborative approach promotes a cohesive care team to provide high-quality patient care.
It’s important for physicians to trust and communicate that PAs and NPs are qualified and capable of providing excellent patient care. Allowing them to care for an established patient does not sever the relationship between the physician and the patient; it can actually enhance the patient’s experience and trust in the practice.
“We want patients who have had a long-standing relationship with an MD to be able to see that doctor, and then we want to help the doctor know and understand how to appropriately transfer care over to an APRN within their system or within their practice,” says Monroe. “So, that provider can be still linked to the doctor, and the doctor can still be linked to the patient.”
Furthermore, physician buy-in is essential for maintaining continuity of care and ensuring patients feel confident in receiving treatment from both physicians and PAs and NPs. When physicians actively endorse interprofessional integration and communicate the benefits of team-based care to their patients, it builds trust and acceptance of the practice model. It also fosters billing transparency if a patient gets an EOB with the name of someone other than the physician as the rendering provider.
Physician engagement is critical for the long-term success and sustainability of integration initiatives. When physicians recognize the value that PAs and APRNs bring to the practice, including increased efficiency, expanded access to care, and improved patient outcomes, they are more likely to champion these initiatives and advocate for their continued support and development.
The Path Forward for PAs and APRNs
The integration of PAs and APRNs into medical practices and health systems presents a strategic opportunity to optimize patient care delivery and operational efficiency. By expanding access to healthcare services and alleviating the workload of overburdened physicians, integration improves patient and employee satisfaction, and enhances patient retention. However, successful integration requires careful attention to regulatory compliance, billing, and coding practices. VMG Health offers comprehensive billing, coding, and strategy advisory services to support practices in navigating the complexities of integration, ensuring compliance with Medicare regulations, and maximizing reimbursement while minimizing audit risk.
Optimal PA and APRN utilization yields tangible benefits, including increased patient access to care, improved patient satisfaction, and enhanced financial performance. By understanding their education, training, and scope, and by leveraging their unique skill sets, practices can accommodate more patients, reduce wait times, and deliver high-quality care cost effectively. Physician engagement is essential for the successful implementation of integration initiatives, as physicians play a pivotal role in endorsing and supporting interprofessional responsibilities within the care team. Through collaborative leadership and effective communication, physicians can foster a culture of teamwork and mutual respect, driving the long-term success and sustainability of integration efforts.
In summary, strategic integration presents a transformative opportunity for medical practices and health systems to meet evolving patient needs, enhance operational efficiency, and achieve sustainable growth. By partnering with VMG Health for expert guidance and support, practices can navigate the complexities of interprofessional integration with confidence, realizing the full potential of this innovative care delivery model.
