Which statement best describes a physician advisor?

• A. A nurse leader overseeing discharge planning.
• B. A pharmacist evaluating drug interactions.
• C. An MD with broad clinical experience who acts as a liaison between hospital staff to ensure regulatory compliance, medical necessity, length of stay, denials, ICD-10 codes, peer review, and utilization of healthcare services.
• D. A resident physician providing direct patient care.

Answer: (C)

The main concept here is understanding what a physician advisor does in hospital utilization management. A physician advisor is a licensed MD with broad clinical experience who acts as a liaison across hospital teams—clinical staff, case management, coding, and administration—to guide decisions about the use of hospital services. Their role is to ensure regulatory compliance, determine medical necessity for admissions and ongoing care, monitor length of stay, help with denials and appeals, verify ICD-10 coding accuracy, and participate in peer review to optimize how resources are used. They provide clinical perspective that supports both patient care quality and appropriate utilization, rather than delivering direct patient care themselves.

The other options describe different roles. A nurse leader overseeing discharge planning focuses on coordinating patient discharge and flow, not the cross-departmental utilization oversight. A pharmacist evaluating drug interactions concentrates on medication safety and pharmacotherapy rather than utilization management and coding. A resident physician providing direct patient care is a trainee delivering care under supervision, not the administrative liaison and utilization review function of a physician advisor.
