33 Medical Billing and Coding Interview Questions & Answers

1. What motivated you to pursue a career in medical billing and coding?

I love that this work connects healthcare and detail. Every accurate code helps a provider get paid and helps a patient’s care make sense on paper, and I am energized by being part of that.

2. What is the difference between ICD-10-CM and CPT codes?

ICD-10-CM codes describe the diagnosis, which is why the patient was seen. CPT codes describe the procedures and services provided. Payers read them together to decide whether a claim makes sense.

3. What is the role of a medical biller?

A biller turns the services a provider delivered into claims, submits them to payers, posts payments, and follows up on denials and unpaid balances. The goal is accurate claims and timely payment.

4. What experience do you have with billing software?

I have worked with [software names] for entering charges, submitting claims and tracking accounts receivable. I learn new systems quickly, and I enjoy mastering the shortcuts that save a team time.

5. How do you ensure coding accuracy?

I read the full documentation, select the most specific code, and check it against the official guidelines and payer policy. When something is unclear, I ask the provider before I submit.

6. How would you resolve a denied claim?

I read the denial reason first, check the documentation and the codes, correct any error, and resubmit or appeal within the payer’s deadline. Then I note the cause so we can prevent it next time.

7. How do you stay current on coding guidelines?

I follow updates from the code set publishers and my credentialing body, take continuing education courses, and review payer bulletins. Codes change every year, and I enjoy keeping up.

8. Why does patient medical history matter in coding?

History gives context about chronic conditions and earlier treatment, which can support medical necessity and specificity. I code only what the documentation supports.

9. What are modifiers and when are they used?

Modifiers add detail to a code, for example when a service was altered, repeated or performed with another procedure. Using them correctly can affect payment, so I check the guidelines each time.

10. Describe a challenging situation and how you handled it.

[Describe a real situation.] For example: when a backlog built up, I sorted claims by deadline and dollar value, worked the most urgent first, and tracked progress daily until we were caught up.

11. What would you do if you found a discrepancy in a patient’s record?

I would not guess. I would bring the discrepancy to the provider through the proper channel, ask for a clarification or a correction in the record, and code only after it is resolved.

12. How do you prioritize during busy periods?

I flag claims by deadline and value, use a tracking list, and protect accuracy first. A fast claim that is wrong costs more time later.

13. What do you know about HIPAA?

HIPAA protects the privacy and security of patient health information. I share information only with authorized people, use only what a task requires, and report any concern about a breach right away.

14. What common coding errors have you seen?

The most common ones are choosing a less specific code than the documentation supports, mismatching a diagnosis and a procedure, and missing or misusing a modifier. I double-check each of these before I submit.

15. Why is the appeals process important?

Appeals give providers a way to challenge a denial and recover payment they are owed. For Original Medicare, the process has five levels, so knowing the deadlines and documentation requirements matters.

16. How do you handle stress?

I stay organized, break work into small steps and communicate early when I need help. I also take short breaks, which keeps me accurate during busy periods.

17. Describe a team project and your role.

[Describe a real project.] For example: I gathered denial data, looked for patterns with my team, and helped update our checklist so the same errors stopped recurring.

18. How would you handle an upset patient about a bill?

I would listen without interrupting, thank them for raising it, explain the charges in plain language and look into anything that seems wrong. I would follow up and keep them informed.

19. What are your long-term goals?

I want to grow into a senior coder or lead role, deepen my specialty knowledge and help train new teammates. I am committed to building a long career here.

20. What certifications do you hold?

[Name only credentials you hold.] I hold the [credential] from [issuer], earned in [year]. If you are still preparing, say: I am preparing for [exam] and plan to take it in [month, year].

21. Are you familiar with telehealth coding?

Yes. Telehealth rules, modifiers and place-of-service requirements vary by payer and change over time, so I always check the current payer policy before I code a virtual visit.

22. What would you do if you made a coding error?

I would correct it right away, tell my supervisor, and follow the process for corrected claims. Then I would look for the cause so I can prevent it.

23. How would you train a new team member?

I would start with a clear checklist, show real examples, let them practice with supervision and check in regularly. I would encourage questions from day one.

24. How do you approach continuing education?

I treat it as part of the job. I schedule time for courses, webinars and publications, and I track the continuing education my credential requires.

25. Why should we hire you?

I bring a passion for accuracy, a strong grasp of the code sets and a drive to keep learning. I take pride in claims that are right the first time, and I am excited to help your team do the same.

26. What is most rewarding about medical coding?

Knowing that my work helps providers get paid and helps patients get the care they need. I enjoy solving the puzzle in a chart.

27. How do you maintain confidentiality?

I follow HIPAA, access only the records I need, lock my screen, and never discuss patient information outside work or in public places.

28. What future challenges do you foresee in this field?

Rules and code sets keep changing, and more care is delivered digitally. I plan to meet that with steady education and careful attention to payer updates.

29. How would you adapt to changes in coding standards?
