Physician Advisor Roles and the
Importance of Certification

Natasha Chen, MD, CHCQM, CPHYADV, FABQAURP

Introduction

A physician advisor is a trained physician who serves as a clinical resource and liaison for hospital administration and medical staff. Physician advisors have a medical degree (M.D. or D.O.), are licensed to practice medicine, and are almost always board certified. They typically have a minimum of three to five years of post-residency clinical experience from any medical specialty.  Experience in the hospital inpatient setting is particularly valuable for this role. Physician advisors are often looked upon as physician champions or leaders. They must have excellent verbal and written communication skills, understand diverse healthcare terminology, and speak the language of administration and finance.  As a liaison between the C-suite, utilization review staff, and medical staff, they must display professionalism and finesse during the occasional difficult conversation. Regardless of background, physician advisors are trained to review diverse clinical scenarios for various purposes and therefore possess a wide breadth of knowledge outside their original field.  

The original function of physician advisors was based on utilization review. Utilization review (UR) was first introduced in the 1960s after President Lyndon B. Johnson signed the Medicare and Medicaid Act (also known as the Social Security Amendments of 1965) into law. The UR process involves checking whether an item or service is medically necessary using established clinical criteria. Medical necessity is a term used to describe health care services or supplies needed to diagnose or treat an illness, injury, condition, disease or its symptoms and meets accepted standards of medicine. Although utilization review was initially performed by registered nurses in the hospital setting, it gained popularity in the health insurance industry. Due to rising healthcare costs and the availability of healthcare insurance from employers, UR was used to reduce waste and overutilization of resources.

Evolution of the Role

The precursor to the physician advisor role seems to have emerged in the 1980s following a transition by Medicare to a new payment method for hospitals based on diagnosis-related group (DRG). This new DRG payment system began in 1983 and emphasized quality of care and appropriate utilization of services. It was predicted to lead to increased interaction between hospital administrators and medical staff, a trend towards salaried service chiefs in community hospitals, and increased scrutiny of physicians' activities. In essence, these early predictions have come true. Early physician advisors in the 1980s and 1990s may have been known as Medical Directors of Utilization Review or Case Management. They provided medical expertise to help guide departments and drive the appropriate utilization of hospital resources from a clinical, quality, and financial standpoint. The formal role of a “physician advisor” was incorporated into the Medical Staff Bylaws manual at Johns Hopkins Hospital in 1990. The term was then adopted by external companies that provided off-site advisory services to hospitals.  

Physician advisors can now be hired directly by a hospital to work on-site or remotely. Services can still be outsourced to a third party, and several companies employ large numbers of physician advisors to provide services to sometimes hundreds or thousands of clients around the United States. There are even hybrid arrangements to include both on-site and remote coverage provided by internal or outsourced physician advisors. In larger hospital systems with multiple physician advisors, each advisor may hold a niche function in one area.  However, most physician advisors are well-versed in multiple areas to provide flexibility and coverage based on the organization’s needs.  

The demand for physician advisors grew in response to growing audit risk. The rollout of Recovery Auditor Contractors (RACs) was likely a major driving force for the growth of the physician advisor field from 2005 to 2010. Physician advisors were used by hospitals to review payment disputes and to appeal to Administrative Law Judges (ALJs) at Medicare Hearings and Appeals (OMHA). The CMS Two-Midnight rule in 2013 was a major regulatory change which defines when inpatient admissions are appropriate for payment under Medicare Part A. Audits by CMS (Centers for Medicare & Medicaid Services) led to physician advisors being at the forefront to help guide medical staff education and documentation efforts. A common trend which followed was health plans scrutinizing inpatient admission decisions, which led to a rise in denials and hospitalizations being approved only as outpatient observation stays. Physician advisors were again needed to overturn denials by performing peer-to-peers, writing statements of support, and appeal letters. They were the natural choice due to their understanding of the complexities of payor behavior, medical necessity criteria, and regulations. With the trend towards value-based care, quality payment plans, and CMS Innovation Center’s testing of new bundled payment models into 2030, the need for the physician advisor skill set will undoubtedly continue to evolve and grow. 

Roles and Responsibilities

The physician advisor’s daily work varies according to the healthcare system, but potential roles and responsibilities are outlined below. As described above, an almost universal role includes utilization review (UR). Specifically, it involves chart reviews, writing secondary (physician level) determinations to support or refute the medical necessity of inpatient admissions, review of outpatient observation stays for either admission or discharge, determining the appropriateness of continued use of hospital resources, and management of denials. These reviews are done either concurrently (patient still in the hospital) or retrospectively (patient has discharged). The UR duties are performed with attention to clinical standards of care, best practice guidelines, and knowledge of the nuances in medical necessity criteria used by CMS, insurers, and commercially available screening tools.  

Regulatory compliance is another key responsibility of physician advisors. Regulations change frequently through federal elections, passage of bills, and world events such as the COVID-19 public health emergency. Physician advisors educate departments and help hospital staff navigate the changing regulatory environment. They can identify early signs of fraud or systemic gaming through medical record review. For example, physician advisors can maintain internal compliance by using a facility’s PEPPER (Program for Evaluating Payment Patterns Electronic Report) to spot potential errors from improper hospital billing or coding. Along the same lines, physician advisors support clinical documentation integrity by promoting accurate and specific documentation of medical conditions. They ensure patient acuity is captured so hospital coders can select the most accurate and best codes to maximize reimbursement. Their work can impact payment from insurers, MS-DRG assignment, and case mix index. Physician advisors are knowledgeable in the complexities of the revenue cycle and hospital reimbursement.  Across all these functions, physician advisors ensure that care is medically necessary, reasonable, evidence-based, and clinically appropriate.

Physician advisors help with patient care progression and coordination. In conjunction with case managers and social workers, they attend multidisciplinary rounds and can assist with length-of-stay (LOS) management and discharge planning. Specific examples include identifying, intervening, and tracking avoidable delays and discharge barriers due to hospital inefficiencies or other factors. For transitions of care, physician advisors contribute by enhancing communication among providers, case management, and patients. They clarify documentation and align care with the appropriate payor status and post-acute setting. They can assist with palliative care screening and goals-of-care discussions which can impact hospital mortality. They can also help review and mitigate readmissions by assisting with early identification and intervention of high-risk patients.  

Another important role is that of a patient advocate. Although physician advisors do not examine, write orders, or provide treatment to the patients they review, they advocate from behind the scenes, ensuring the appropriate level of care is delivered.  As described above, they intervene on insurance denials, improve clinical documentation accuracy for the medical record, collaborate with case management to reduce delays, and support timely discharge planning. Their role helps to drive quality and safety. Physician advisors ensure the right care is delivered at the right time in the right setting. They can help support evidence-based practice and standardized protocols. They can assist with ethical concerns, patient throughput, and reduction of hospital-acquired complications through LOS management. Their focus is always on high-quality outcomes and patient- and family-centered care delivered safely and efficiently.  Physician advisors do all these things while applying national guidelines and intervening in complex situations where the needs of patients and hospital systems must be carefully balanced to maintain quality and financial health.  

Physician Advisor Certification

Physician advisors are expected to complete self-guided, ongoing continuing medical education (CME) in both their medical specialty and the physician advisor field. Many employers require board certification in a medical specialty, and some also require or prefer physician advisor certification. The American Board of Quality Assurance and Utilization Review Physicians (ABQAURP) provides a large selection of online education and two certification programs specifically for physician advisors. These include the Health Care Quality and Management Physician Advisor sub-specialty (CHCQM-PHYADV) and the Advanced Physician Advisor (CPHYADV) board certifications. Online educational resources are available for each as a means to prepare or refresh knowledge in the domains of each certification area (HCQM and Advanced Physician Advisor Core Body of Knowledge). Physician advisor certification validates expertise and helps demonstrate competency. It shows commitment to the field and helps physicians stay current in the areas of patient care, utilization, regulations, quality, and patient safety. In many cases, certification leads to professional growth, new opportunities, and career advancement. 

For hospitals and healthcare organizations, promoting physician advisor certification can strengthen public trust and highlight the organization’s commitment to high standards. Organizations can promote physician advisor certification through websites, brochures, and other marketing materials that explain how physician advisors support quality, safety, efficiency, compliance, evidence-based care, and responsible stewardship of resources. Hospitals can boost their public profile and maybe even their star ratings by emphasizing they have a certified physician advisor program that exists to better ensure patient care adheres to national standards, improves the accuracy of medical records, and brings specialized expertise to complex care management.  

In summary, certified physician advisors are valuable resources within hospitals and healthcare organizations. They have a wide range of expertise and skills across multiple healthcare fields and can serve as an administrative liaison to bridge clinical care, regulatory compliance, utilization management, care coordination, clinical documentation improvement, quality, safety, and patient advocacy. What was once an occasional side-job for a few hours a week has become a full-blown career field with many hospitals and healthcare systems having one or multiple physician advisors. Finally, a certified physician advisor is a major asset to an organization and can help create opportunities to collaborate, improve care delivery, and better support both patients and the healthcare team.
