Top Medical Billing interview Questions & Model Answers
1. Tell me about yourself and why you want a medical billing role
- Key Points:
-
-
-
-
sample Answer: “I’ve spent the last three years specializing in outpatient medical billing, focusing on accurate CPT/HCPCS coding and ICD-10-CM diagnoses. I’ve reduced claim denials by 18% through precise modifier usage and careful chart review. I’m confident in navigating payer policies, HIPAA compliance, and EHR-integrated billing workflows. I’m pursuing CPC certification to deepen my coding proficiency, and I’m excited to bring that expertise to a dynamic team like yours.”
2. What is your experience with CPT/HCPCS coding?
- Key Points:
-
Sample Answer: “In my previous role, I prepared and reviewed CPT/HCPCS coding for all outpatient visits and procedures, staying current with annual CPT changes and Medicare/Commercial payer guidance. I performed monthly internal audits to catch upcoding or undercoding, collaborated with clinicians on ambiguous codes, and implemented a quick-reference CPT cheat sheet that reduced coding errors by 12%.”
3. How do you handle ICD-10-CM coding and ensure accuracy?
- Key Points:
-
-
-
Sample Answer: “I start with the encounter reason, review the patient’s history, and confirm the principal and secondary diagnoses. I ensure specificity (three- to five-character codes when possible), check for laterality, and verify that codes align with documented symptoms and treatments. I perform chart reviews for any ambiguous entries and consult guidelines to avoid miscoding.”
4. What is denial management, and how do you reduce claim denials?
- Key Points:
-
-
Sample Answer: ”Denial management is about preventing denials, identifying root causes, and efficiently appealing or resubmitting when needed. I track denial types (eligibility, coding, medical necessity, missing information), implement pre-submission edits to catch errors, and monitor denial trends monthly. When a denial occurs, I document the reason, align with payer policies, and prepare compelling appeals with supporting documentation.”
5. How do you stay updated with payer policies and HIPAA compliance?
- Key Points:
-
-
-
Sample Answer: “I subscribe to payer policy updates, participate in AAPC webinars, and maintain ongoing training in HIPAA, PHI handling, and data security. I also review payer-specific guidelines before submitting claims and document any policy changes to ensure ongoing compliance.”
6. Explain the difference between a clean claim and an error claim,and how you ensure clean claims
- key Points:
-
-
-
Sample Answer: ”A clean claim has complete, accurate information that aligns with payer rules, minimizing the chance of denial. I ensure cleanliness by double-checking demographics,dates of service,diagnosis-to-procedure alignment,proper modifiers,and any required authorizations before submission,plus a quick post-submission audit for accuracy.”
7. What is CPT modifier 25, and when would you use it?
- Key Points:
-
-
-
Sample Answer: “Modifier 25 is used to indicate a separate E/M service on the same day as a procedure. You use it when the patient receives an evaluation and management service that is distinct from the procedure performed, and the documentation clearly supports the need for both. It’s crucial to ensure the E/M service is primary in documentation and billed with the correct CPT code.”
8. How do you handle a denied claim with a payer?
- Key Points:
-
Sample Answer: ”I start by reading the denial reason, then verify patient demographics, coverage, and eligibility. I gather supporting documentation (progress notes, orders, medical necessity). If eligible for appeal, I submit with a concise, evidence-based argument and required forms, and I monitor the appeal until resolution. I also log the denial to identify trends for proactive prevention.”
9. What experience do you have with EHR-integrated billing systems and RCM software?
- Key Points:
Sample Answer: “I’ve used Epic’s billing module extensively, along with a cloud-based RCM platform for claim submission, denial tracking, and AR aging reports. I focus on data integrity, workflow automation, and generating actionable metrics for leadership to drive improvements in cash flow.”
10.Can you give an example of how you improved a key metric (e.g., denial rate or days in AR) in a prior role?
- Key Points:
-
-
sample Answer: “in my last role, I reduced the denial rate by 15% over three months by implementing a daily denial review routine, focusing on the top denial reasons, and creating a quick-reference guide for coders and clinicians. We also standardized modifier usage and introduced monthly refresher sessions to sustain the advancement.”
11. What certifications do you have,and how do they support your medical billing work?
- Key Points:
-
-
-
Sample Answer: “I hold CPC and CPB certifications through the AAPC and CBCS through the NHA. These credentials reinforce my coding accuracy, payer policy knowledge, and ethical billing practices. I’m committed to ongoing education and plan to pursue a CHBMS or CPC-A certification as I gain more leadership obligation.”
12. How do you approach compliance with HIPAA and protecting patient information in daily work?
- Key Points:
-
-
-
Sample Answer: “I follow strict access controls, encrypt data in transit and at rest, and only access PHI on a need-to-know basis. I complete periodic HIPAA training, secure documents, and report any potential breaches promptly. I also practice secure messaging and proper disposal of PHI according to policy.”
