Why pre-screen medical billing assistants before the practice interview
Most of the money lost in medical billing goes unnoticed. A claim is denied for a fixable reason, nobody works the denial before the appeal window closes, and the practice writes off revenue it had already earned. Assistants worth hiring know their denial rate and their most common reason, and they chase. A short screen asks for both numbers, which separates people who own the process from people who submit claims.
What actually matters when screening Medical Billing Assistant candidates
- 01
Execution and reliability
Check daily claim volume handled, clearinghouse and PM systems used (Availity, Kareo, Epic, AdvancedMD), CPT/ICD-10 and modifier accuracy, plus clean claim rate and AR days.
- 02
Improving the process
Probe changes they made to reduce denials: worklist triage rules, eligibility checks before visits, superbill templates, or aging report cadence that shortened AR over 90 days.
- 03
Judgement and autonomy
Assess how they handle a CO-16 or CO-97 denial, an underpayment versus contracted rate, patient balance disputes, and when to escalate to the coder or provider.
- 04
Communication
Judge how they explain an EOB or unexpected balance to an upset patient, chase payer reps for claim status, and document HIPAA-safe notes in the account.
Pre-screening questions to ask Medical Billing Assistant candidates
12 questions grouped by what they test. Ask the same set in every screen and score answers on a consistent scale, or send them as an async video screen and compare answers side by side.
Billing they owned
3 questions01What experience do you have with medical billing software, and which systems have you used?
Listen forNamed systems used daily with claim volumes, and what they handled without a supervisor checking.
Systems named with no volume attached, or a role that turns out to be data entry only.
02What is your experience handling insurance claims and payer policies?
Listen forSpecific payers named with their particular requirements, since rules differ substantially between insurers.
Payers treated as interchangeable, or no awareness that requirements differ by insurer.
03Describe your experience with financial reporting and reconciling billing accounts.
Listen forPayments reconciled against the expected allowed amount, with underpayments identified and pursued rather than posted and accepted.
Payments posted without checking against the allowed amount, or underpayments never pursued.
Accuracy as routine
3 questions04Can you describe your understanding of medical coding systems?
Listen forWorking knowledge of the code sets in use, with a clear line on what they will not code without clarification.
Codes selected to secure payment, or documentation gaps filled by assumption rather than by asking.
05How do you ensure accuracy when entering billing information?
Listen forA checking routine before submission, with an error they caught and what they changed afterwards.
Accuracy described as being careful, or checking that only happens when there is time.
06Tell us about a time when you had to resolve a billing error. How did you handle it?
Listen forAn error found and corrected properly, including telling the patient or payer rather than adjusting silently.
Errors corrected without informing anyone, or overpayments retained rather than refunded.
Denials worked
4 questions07Describe your process for handling denied or rejected claims.
Listen forDenials worked systematically with the reason coded and tracked, and appeals filed within the window.
Denials written off without investigation, or appeal deadlines missed because nothing was tracked.
08How do you handle following up with providers or insurers for missing information?
Listen forPersistent follow-up with a tracking method, including how they get information from a busy clinician.
Requests sent once with no follow-up, or claims held indefinitely waiting on someone else.
09What strategies do you use to ensure timely submission of claims?
Listen forSubmission within a target from date of service, with a figure they can quote and a backlog rule.
No submission target, or claims submitted late enough to risk timely filing limits.
10What methods do you use to verify patient insurance information and eligibility?
Listen forEligibility verified before the visit where possible, with coverage limits checked rather than assumed.
Eligibility checked only after a denial, or coverage assumed from a card presented at reception.
Patients and privacy
2 questions11What steps do you take to protect patient confidentiality and meet privacy requirements?
Listen forMinimum necessary access applied in practice, with a clear rule on what may be discussed with a family member.
Account detail given to whoever calls, or records accessed with no business reason.
12Describe your experience with patient billing and handling difficult payment conversations.
Listen forCharges explained clearly with options offered, and the bill checked for errors before it is defended.
Conversations framed as collections, or bills defended without first verifying they are correct.
How to score responses
Score every candidate on the same four criteria immediately after the screen. At this stage you are shortlisting for panel interviews, not making the final call.
Execution and reliability
35%5Cites claims processed per day, first-pass acceptance above 95 percent, and names specific payer portals and practice management systems used.
Improving the process
25%5Describes a concrete fix, such as front-end eligibility verification, with before and after denial or AR aging numbers attached.
Judgement and autonomy
25%5Distinguishes rebill, appeal, and write-off decisions confidently, knows appeal deadlines, and escalates coding questions rather than guessing modifiers.
Communication
15%5Explains coinsurance and deductible plainly without jargon, keeps clear account notes with reference numbers, and stays composed on collections calls.
A denial nobody works before the appeal window closes is revenue already earned and written off. A one-way video screen asks for their denial rate.

Process basics
How long should a pre-screening round for this role take?
Ten to fifteen minutes across eight to ten questions, answered async. Enough to establish what they owned, test their coding and accuracy practice, and hear how they work a denied claim.
How much does payer and jurisdiction experience matter?
A great deal. Coding conventions, payer rules and appeal windows differ by system and by insurer, and someone strong in one environment starts near the beginning in another. Ask which payers they have worked with.
Evaluating answers
What is the strongest signal when screening this role?
Their denial rate and its most common cause. Assistants who own the process know both and can describe what they changed to reduce it. Anyone who has never tracked denials has been submitting rather than managing.
How do I judge their handling of patients?
Ask how they discuss an unexpected bill. Sound answers explain the charge clearly, check eligibility was applied correctly and offer options. Anyone who describes it as collections will generate complaints.
