Clear communication and teamwork between billing and clinical staff are vital to prevent future errors.
16. Describe the End-to-End Medical Billing Process.
How to Answer: Outline the steps clearly from start to payment posting.
Sample Answer:
The billing process begins with patient registration and insurance verification. Next, providers document services, and coders assign appropriate ICD and CPT codes. Billers then generate and submit claims electronically or on paper. After submission, the payer reviews the claim, issues payment, or provides an explanation of benefits (EOB). If denied, billers review, correct, and resubmit claims. Once payments are received, I post them to the patient’s account and reconcile balances. This cycle continues until the provider is fully reimbursed. Efficiency and accuracy at each stage ensure smooth revenue flow and compliance.
17. How Do You Handle Unpaid Claims That Are Over 30 Days Old?
How to Answer: Emphasize follow-up and documentation.
Sample Answer:
For unpaid claims over 30 days old, I review their status in the billing system to identify the cause. If they are pending with the payer, I follow up by phone or through the payer portal. If denied, I investigate, correct, and resubmit. I also document every follow-up action for accountability. In my last position, I maintained a 15-day follow-up schedule that helped recover thousands in aged receivables. Timely follow-up is essential for maximizing collections and maintaining a steady revenue cycle.

Empathy and clear communication help maintain trust while ensuring accurate billing outcomes for both patients and providers.
22. What Are CPT Code Modifiers 25 and 59 Used For?
How to Answer: Define both with examples.
Sample Answer:
Modifier 25 is used to indicate a significant, separately identifiable evaluation and management (E/M) service performed on the same day as another procedure. Modifier 59 indicates a distinct procedural service that should not be bundled with another. For instance, if a patient has an office visit and a minor procedure, modifier 25 is applied to the E/M code. Modifier 59 might apply when two unrelated procedures occur in one visit. Using them correctly prevents underpayment or denials. I always confirm documentation supports modifier use before submission.
23. How Do You Handle Recurring Denials From a Specific Insurance Provider?
How to Answer: Show problem-solving and process improvement.
