✍️ Sample PACS Questions & Answers
1. What should be included in a prior authorization request?
A complete prior authorization request must include specific details to allow the insurance company to make an informed decision. This includes patient demographics (name, date of birth, insurance ID), provider information (NPI, facility name), and comprehensive clinical service information (diagnosis codes, procedure codes, medical necessity justification, and supporting documentation). Missing any of these elements can lead to delays or denials.
2. What is the purpose of a 'retrospective review' in utilization management?
Retrospective review evaluates the medical necessity and appropriateness of services that have already been provided, often affecting payment decisions.
3. Which of the following is NOT typically a valid ground for a prior authorization appeal?
Patient preference alone is not a valid clinical or procedural ground for an appeal; appeals must be based on medical necessity, coverage criteria, or procedural errors.
4. What does 'compliance' mean in healthcare settings?
In healthcare, 'compliance' refers to adhering to all applicable laws, regulations, policies, and ethical standards set by governmental bodies and the organization itself. This includes rules related to patient privacy, billing, quality of care, and safety. Maintaining compliance is crucial for legal operation, patient safety, and maintaining public trust.
5. A health plan wants to audit whether its PA reviewers are applying clinical criteria consistently. Which audit methodology is MOST appropriate?
An inter-rater reliability study compares decisions made by different reviewers on identical cases to assess consistency in criteria application.
6. An authorization was granted six months ago but the patient never received the service. How should this record be documented?
Expired authorizations must be retained with an 'expired/unused' notation to maintain an accurate audit trail.
