What is considered the core skill of the auditor?

• A. Knowledge of coding and billing systems.
• B. Ability to observe provider behavior during visits.
• C. Understanding how to find and differentiate between controlling and persuasive criteria.
• D. Proficiency in statistical sampling.

Answer: (C)

Auditors must know how to find and differentiate between controlling criteria and persuasive criteria. Controlling criteria are the rules, standards, or statutes that have the authority to determine whether something meets requirements in a given situation. Persuasive criteria are supportive sources—guidance, best practices, or interpretations—that help explain or justify judgments but do not carry the same binding force as controlling criteria. The core skill is precisely identifying the applicable controlling criteria and applying them consistently to your audit findings, then using persuasive criteria only to provide context or rationale when appropriate. This ensures conclusions are grounded in mandatory standards and are defensible. While other abilities, like understanding coding and billing systems, observing provider behavior, or using statistical sampling, are useful tools in the audit process, they do not replace the fundamental need to locate and apply the controlling criteria that drive the final determination.
