Employing Non-Physician Practitioners: Benefits and Compliance Considerations

Traditionally, it was only “doctors” that provided medical care to patients – likely with the help of some sort of unlicensed assistant – and doctors would, therefore, limit their billing (and revenue) to the services that they, individually, provided. In recent years licensed and/or certified non-physician practitioners (“NPP’s”) have begun to provide an increasing amount and variety of medical care to patients and, accordingly, increase the amount of reimbursement and revenue to health care practices that utilize the services of an NPP.

The regulations and statutes regarding NNP education, scope of practice, supervision and training are primarily based on state laws and, in many ways, differ from state to state. The designation and variety of NPP’s also vary from state to state, but, generally speaking, NPP’s can be categorized as follows:

  • Advanced Practice Nurse
  • Certified Registered Nurse Anesthetist
  • Clinical Nurse Specialist
  • Clinical Psychologist
  • Clinical Social Worker
  • Nurse Midwife
  • Nurse Practitioner
  • Occupational Therapist
  • Physician Assistant
  • Physical Therapist
  • Speech Pathologist
  • Surgery Assistant

Billing and Reimbursement for Non-Physician Practitioner Services

Reimbursement received by health care practices for services provided by NPP’s varies substantially among federal, state and commercial payors, and should be thoroughly evaluated prior to submission of medical bills. For instance, Medicare will reimburse for services provided by certain NPP’s in private physician practices when:

(1) The bill for NPP services is submitted using the NPP’s own name and national provider identifier (“NPI”) number. The NPP is reimbursed at eighty-five (85%) percent of the Medicare physician fee schedule.

(2) The bill for NPP services is submitted using the supervising physician’s NPI as “incident to” the services provided by the physician. The NPP’s services will be reimbursed at One Hundred (100%) percent of the Medicare physician fee schedule. Further, if covered NPP services are furnished, then services and supplies furnished incident to the NPP’s services may also be covered.

In order for a health care practice to submit a bill to Medicare for NPP services provided “incident to” the services of the supervising physician, the following criteria must be met:

(a)   The NPP services must be performed under the direct supervision of the physician as an integral part of the physician’s personal in-office service (this does not mean that each occasion of an incidental service performed by a NPP must always be the occasion of a service actually rendered by the physician.

(b) There must be a direct, personal, professional service furnished by the physician to initiate the course of treatment of which the service being performed by the NPP is an incidental part, and there must be subsequent services by the physician of a frequency that reflects the physician’s continuing active participation in and management of the course of treatment;

(c)   The supervising physician must be physically present in the same office suite and be immediately available to render assistance if that becomes necessary;

(d) Also, a physician might render a physician’s service that can be covered even though another service furnished by a NPP as incident to the physician’s service might not be covered.

In practice, this translates to the following criteria:

(1) The supervising physician initially sees the patient (or sees the patient at a previous visit) and initiates the plan of care that the NPP is carrying out.

(2)The supervising physician remains involved in the patient’s care and continuously documents this involvement in the patient’s medical record.

(3)The NPP is an employee and/or independent contractor associated with the physician practice.

(4)The supervising physician (or another physician of the physician practice) must be in the medical office at all times that the NPP provides services and must be immediately available to intervene in the patient’s care if medically necessary.

Commercial payors, on the other hand, are free to set their own policies and guidelines for credentialing NPP’s and providing reimbursement for their services. Some commercial payors are willing to credential NPP’s and allow NPP services to be reimbursed using the NPP’s own provider number or instruct physician practices to bill for services provided by the NPP under the supervising physician’s provider number as “incident to” the services provided by the supervising physician. Other commercial payors simply refuse to reimburse for services provided by an NPP altogether. It is also important to note that a health care practice may be able to negotiate the reimbursement rate provided by certain commercial carriers for services provided by NPP’s.

Additionally, federal, state and commercial payors each have unique restrictions and guidelines concerning an NPP’s ability to examine and treat new patients, patients with new or worsening conditions, and so forth. Accordingly, health care practices should always request and keep on file each payor’s written policy concerning qualification, billing, coding and reimbursement of NPP services.  

What Are The Benefits Of Using A Third Party Medical Billing Company?

Over the past few years health care providers have reported an increasing surge in the outsourcing of medical billing and collections  to third party medical billing companies.  The outsourcing surge stems from a number of factors, most of which are focused on increasing revenue and surviving payor scrutiny.  

First, health care providers rely on medical billing companies to assist them with processing claims in accordance with applicable rules, regulations, laws and statutes (“health care laws”).  With the increasing complexity of the health care industry, the demand for familiarity with health care laws can be overwhelming for health care providers and will often require the education, knowledge and skill of an independent professional.

Second, health care providers are increasingly consulting with medical billing companies to provide them with timely and accurate advice regarding reimbursement matters and overall business decisions.  Medical billing companies normally support a variety of providers and organizations with different specialties and, therefore, have a unique insight to reimbursement issues, as well as diagnosis and procedure code utilization and optimization.  The critical component is a medical billing company’s ability to conduct practice-to-practice comparisons and data mining of coding, billing and collection patterns.

Third, medical billing companies normally have professionals dedicated to specific specialist and/or process areas, thereby increasing employee efficiency, skill and knowledge within the assigned area.  For instance, professionals skilled in collecting unpaid cardiology claims will have the benefit of uncovering and monitoring payor patterns of rejection and denial, and will have the insight to determine which coverage determinations are worth fighting or which coding practices to alter.  

Fourth, in most cases a medical billing company will consistently provide clients with customized practice reports and analytics that offer an in depth look at key metrics an allow the provider to make informed, strategic, decisions concerning billing, coding and collections.  While most of this data and analysis can be conducted in-house, is often underutilized or overlooked altogether with small physician practices. 

Finally, another issue that small physician practices face with in-house medical billing is hiring, training and maintaining an adequate medical billing staff.  Normally, small physician practices allocate one to two designated staff members for medical billing and collection purposes and suffer the consequences of insufficient and inefficient staff in the form of timely filing issues, timely appeal issues, lack of follow up and collections, contractual allowances and, ultimately, write offs.

It is important to note that third party medical billing companies significantly vary in terms of the type of services provided and the manner in which these services are provided for their respective clients. For example, some medical billing companies provide coding services for their clients, while others only process pre-arranged Superbills that have already been coded by the provider.  Additionally some medical billing companies offer a spectrum of management services, including patient intake support, accounts receivable management and debt collections. 

The main question to consider when determining whether to use an in-house medical billing professional or to outsource to a outside medical billing company is “what are you coding and billing, and why?” If the answer to this simple question is not supported by customized practice reports and analytics, strategic and informed, decisions concerning the coding, billing and collections choices made for each patient, and driven by the voluminous rules, regulations and statutes affecting health care practice, then the answer is flawed and is likely costing the practice critical revenue.
