Likely interview questions for this role
Written from this job description, not a generic list. Each one notes what the interviewer is really checking.
About your past
Tell me about a time your clinical background helped you catch something that a coder alone might have missed.
What they are checking: Whether they truly combine nursing judgment with coding knowledge, which is the point of this role.
How do you keep up with changes in CPT codes, state Medicaid rules and payment policies?
What they are checking: Commitment to staying current, since outdated knowledge leads to wrong findings.
How do you stay objective when the evidence points both ways on a claim?
What they are checking: Fairness and neutrality, because investigators affect providers' income and reputations.
What would you do
A provider calls upset about your findings and says you don't understand their specialty. How do you respond?
What they are checking: Ability to stay professional, explain the basis for findings and stay open to valid clinical context.
After a review, how would you recommend changes so the same problem doesn't happen again?
What they are checking: Whether they think about prevention and provider education, not just recovering money.
About the work
Walk me through how you'd review a medical record against the claim to decide whether a billed service is supported.
What they are checking: Whether they have a disciplined method for matching documentation to CPT codes and payment policy.
What billing patterns would make you suspect a provider is upcoding or unbundling?
What they are checking: Practical knowledge of common fraud and abuse patterns that a Special Investigation Unit looks for.
How do you tell the difference between a provider making honest coding mistakes and one committing fraud or abuse?
What they are checking: Whether they can separate error from intent, which changes the recommendation and its consequences for the provider.
What's the difference between a prepayment review and a retrospective review, and how does your approach change?
What they are checking: Understanding of how timing affects the work, the provider impact and what evidence is available.
How do you write a summary of findings so it holds up if the provider appeals?
What they are checking: Whether their writing is factual, cites the policy and record, and would stand up to scrutiny.
