20 Medical Billing Interview Questions with Answer Guidance

The top 10 medical billing interview questions

1. What is medical billing? Explain the full claim-to-payment process, not only data entry.
2. Walk me through the claim lifecycle. Cover registration, eligibility, coding, submission, adjudication, posting and follow-up.
3. What is the difference between a rejected and denied claim? A rejection usually fails before adjudication; a denial is adjudicated but not paid as billed.
4. How do you verify eligibility? Confirm active coverage, dates, plan, payer, benefits, patient responsibility and authorization requirements.
5. How would you work a denial? Read the reason, verify facts and deadlines, correct or appeal with support, document and follow up.
6. What are ERA and EOB? Explain electronic/paper remittance information and how it supports posting and follow-up.
7. What is timely filing? A payer’s deadline for initial claims or later actions; verify the contract and current payer rule.
8. How do you prioritize A/R? Consider filing deadlines, balance, age, denial reason, payer response and probability of action.
9. How do you protect patient information? Use authorized systems, minimum necessary access and approved communication channels.
10. What would you do if you were unsure? Pause, check the documentation and rule, then escalate rather than guess.

How should a fresher answer?

Do not invent experience. Use training exercises, university work, internships or other roles to show accuracy, communication and ownership. A useful structure is: what you understood, what steps you would take, what you would verify and when you would escalate.

What is a good answer for three weaknesses?

Choose genuine, non-fatal development areas and explain the control you use. For example:

• I used to spend too long checking routine work. I now use a checklist and time-box the first review while escalating true exceptions.
• I was hesitant to ask questions early. I now document what I checked and escalate before a deadline is at risk.
• My payer-call confidence was limited. I practice a call structure, prepare the account facts and summarize every outcome in writing.

Avoid weaknesses that directly contradict the role, such as ignoring details, mishandling confidentiality or being unwilling to learn.
