Interview Questions to Ask a Medical Coder / Biller Candidate
Questions that surface real evidence of coding accuracy that keeps claims from being denied or delayed — plus what to actually listen for in the answer, not just whether they say the right buzzwords.
1. How do you decide the correct diagnosis and procedure codes when the clinical note is incomplete?
What to listen for: Not assuming, querying the provider, following coding guidelines, and documenting the query.
2. A claim is denied for medical necessity. What are your next steps?
What to listen for: Reviewing denial reason, checking documentation and codes, correcting or appealing, and tracking outcomes.
3. A physician asks you to code a higher-paying service that the note does not support. What do you do?
What to listen for: Refusing to code unsupported services, explaining compliance risk, and escalating if needed.
4. You are behind on a coding backlog and month-end is near. How do you prioritise?
What to listen for: Ordering by age and value of claims, keeping accuracy, and asking for help instead of rushing.
5. What would you do in your first 30 days in this medical coder / biller role?
What to listen for: Whether their plan is grounded in the role's actual must-haves (icd-10 coding and cpt coding) or generic ("get to know the team"). Specificity here signals real understanding of the job, not just interview prep.
6. Why are you leaving your current role, and why this one specifically?
What to listen for: Forward-looking motivation tied to something concrete about this role, versus badmouthing a past employer or vague dissatisfaction. Watch for whether their reasons actually match what this role offers.

Frequently asked questions
How many of these questions should I ask in one interview?
3-4 is realistic for a 30-45 minute interview once you leave room for follow-ups and the candidate's own questions. Divide competencies across panel members rather than every interviewer asking all of them — see the Interview Scorecard tool for a structured version of this.
