How to use this page
Don't memorise answers. For each question, read what the interviewer is looking for, then practise answering out loud in your own words with a real example. The notes describe strong answers and common red flags — they are for your prep, not a script.
ICD-10 Coding
1 questionWalk me through how you assign an ICD-10 diagnosis code from a physician's note.
IntermediateWhat the interviewer is looking for: Strong answers read the full documentation, code to the highest specificity supported, and never assume beyond what is documented. Coding from an incomplete note or guessing is a red flag.
CPT Coding
1 questionHow do you select the correct CPT code and applicable modifiers for a procedure?
AdvancedWhat the interviewer is looking for: Look for matching the procedure to the right code, correct modifier use, and avoiding upcoding or unbundling. Applying modifiers to boost reimbursement improperly is a serious red flag.
HCPCS Coding
1 questionWhen do you use HCPCS codes, and how do they differ from CPT?
IntermediateWhat the interviewer is looking for: Strong candidates know HCPCS covers supplies, drugs, and services beyond CPT, and apply them correctly. Confusing the code sets is a red flag.
Coding Compliance
2 questionsThe documentation does not support the code the provider expects. What do you do?
AdvancedWhat the interviewer is looking for: Look for querying the provider for clarification and coding only what is documented, never fabricating support. Coding unsupported services is a serious compliance red flag.
How do you keep up with annual coding updates and guideline changes?
BasicWhat the interviewer is looking for: Strong candidates track annual ICD/CPT updates and payer rules and apply them promptly. Coding from outdated books is a red flag.
HIPAA
1 questionHow do you ensure your coding stays HIPAA compliant?
BasicWhat the interviewer is looking for: Strong answers protect PHI, access only what is needed, and follow privacy and security rules. A casual attitude to patient data is a serious red flag.
Revenue Cycle Management
1 questionHow does accurate coding affect the revenue cycle?
IntermediateWhat the interviewer is looking for: Look for understanding that coding drives clean claims, reimbursement, and denials, and its downstream financial impact. Seeing coding as isolated from revenue is a red flag.
Denial Management
1 questionHow do you handle and reduce claim denials related to coding?
IntermediateWhat the interviewer is looking for: Strong candidates analyse denial reasons, correct and appeal appropriately, and fix root causes to prevent recurrence. Just resubmitting without understanding the denial is a red flag.
Medical Terminology
1 questionHow do you interpret medical terminology to code accurately across specialties?
IntermediateWhat the interviewer is looking for: Look for solid terminology and anatomy knowledge and looking things up when unsure. Guessing at unfamiliar terms is a red flag.
Attention to Detail
1 questionWhy is meticulous attention to detail essential in medical coding?
BasicWhat the interviewer is looking for: Strong answers know a single wrong digit affects reimbursement and compliance, and use careful review. Carelessness is a serious red flag in coding.
Claims Processing
1 questionHow do you process claims accurately and efficiently under production targets?
IntermediateWhat the interviewer is looking for: Look for balancing accuracy with speed and never sacrificing accuracy to hit quotas. Cutting corners for volume is a serious red flag.
Electronic Health Records
1 questionHow do you use EHR systems effectively in your coding workflow?
BasicWhat the interviewer is looking for: Look for navigating records to find supporting documentation and coding from the complete record. Coding from summaries without checking the full record is a red flag.
Compliance
1 questionA supervisor pressures you to code in a way that increases reimbursement but is not supported. How do you respond?
AdvancedWhat the interviewer is looking for: Strong answers refuse to code unsupported services, cite compliance, and escalate. Caving to pressure to upcode is a serious compliance red flag.
Behavioural & role-general
2 questionsTell me about a time you caught and fixed a coding or documentation issue.
BasicWhat the interviewer is looking for: Look for vigilance, appropriate follow-up, and protecting compliance. Being unable to give an example suggests weak attention to accuracy.
Why did you choose medical coding, and how do you keep your certifications current?
BasicWhat the interviewer is looking for: Strong answers show genuine interest and ongoing CEU/certification maintenance. No plan to stay current is a concern in this field.
