Medical billing specialist interview questions for remote roles
Remote billing interviews are practical. Expect a recruiter screen, then a team lead who reads you a denial or shows you an EOB and asks what you'd do. Some RCM firms add a typing or Excel test and a mock call to an insurer.
The questions below are the ones that come up again and again, with answers pitched the way a Nigerian candidate with some experience would give them.

About the role and your experience
Openers that check you understand the job and have done the work.
Walk me through the medical billing cycle from appointment to payment.
Why they ask
It's the fastest way to see whether you understand the whole process or only one task.
How to answer
Go in order and name the hand-offs: registration and eligibility, charge capture and coding, claim scrubbing and submission, adjudication, payment posting, denial work, patient statements. Keep it under two minutes.
Show a sample answerHide the sample answer
It starts before the visit with eligibility and benefits. After the visit the coder sends CPT and ICD-10 codes, I enter the charges and scrub them, and the claim goes out as an 837P through the clearinghouse. When the ERA comes back I post the payment and adjustments, work any denial, and send the patient a statement for their share.
Technical questions
What you know and how you'd do the work, often with a live task or test.
A claim came back with CO-197. What does it mean and what do you do?
Why they ask
Denial codes are the daily work. They want to know you can read one without looking it up every time.
How to answer
Say what it means (precertification or authorisation missing), then the steps: check whether an auth was obtained, attach it and resubmit, or request a retro-auth or appeal if the payer allows it. Mention that you'd flag the front desk so it doesn't repeat.
Show a sample answerHide the sample answer
CO-197 means the payer has no record of the prior auth. I'd check the chart for an auth number first, because sometimes it was obtained but not put on the claim. If there's none, I'd see if the payer accepts a retro-auth, and I'd tell the front desk which service triggered it so we fix it upstream.
What's the difference between a rejection and a denial?
Why they ask
Mixing them up wastes days. A rejection never reached adjudication; a denial did.
How to answer
Rejection: the clearinghouse or payer bounced it for format or data errors, fix and resend. Denial: the payer processed it and refused, so you correct, resubmit or appeal depending on the reason.
What does timely filing mean, and what happens if you miss it?
Why they ask
Missing filing limits is the most expensive mistake a biller can make.
How to answer
Each payer sets a deadline to submit or correct a claim after the date of service. Medicare's is generally one year. Missed means it's usually written off unless you can prove an earlier submission, so you keep clearinghouse acceptance reports.
Explain modifiers 25 and 59.
Why they ask
Modifier errors cause a big share of denials on doctor claims.
How to answer
25: a significant, separately identifiable E/M service on the same day as a procedure. 59: a distinct procedural service, used to show two procedures shouldn't be bundled. Say you'd query the coder rather than add one yourself when the notes don't support it.
How do you post a payment from an ERA where the payer paid less than expected?
Why they ask
Posting errors make patient balances wrong and hide underpayments.
How to answer
Post exactly what the ERA shows, using the contractual adjustment and patient-responsibility codes, then compare the paid amount to the fee schedule. If it's an underpayment, flag it for follow-up rather than adjusting it off.
Which billing software have you used?
Why they ask
Training time costs them money, so they look for systems they already use.
How to answer
Name each one and what you did in it. If you haven't used theirs, say which similar one you know and how quickly you picked it up.
How do you check eligibility, and what do you look for?
Why they ask
Bad eligibility checks cause avoidable denials.
How to answer
Portal or 270/271 check through Availity or the payer site. Confirm active coverage on the date of service, plan type, in or out of network, deductible met, co-pay, and whether the service needs prior authorisation.
Behavioural questions
Past situations. Answer with a real example: what happened, what you did, what changed.
Tell me about a denial you got overturned.
Why they ask
They want proof you've actually done appeals, not just read about them.
How to answer
One specific case: the denial reason, what evidence you gathered, how you wrote the appeal and the result. Numbers help.
Show a sample answerHide the sample answer
We had a run of medical-necessity denials from one payer for therapy sessions. I pulled the treatment plans, matched each session to the diagnosis the payer's policy listed, and sent appeals with the policy section quoted. Eleven of fourteen were paid within six weeks, about $3,800 for a small practice.
Why do you want to work in US medical billing rather than a local role?
Why they ask
They want to know you'll stay through the night shifts and the learning curve.
How to answer
Be honest and specific: the career path, the certificate you're working towards, an interest in how US insurance works. Avoid making it only about money.
Situational questions
Hypotheticals about problems you'd meet in the job.
How do you prioritise an AR list of 400 unpaid claims?
Why they ask
Shows whether you think about money and deadlines or just work top to bottom.
How to answer
Sort by filing or appeal deadline first, then by balance, then by payer. Group claims by payer so one call clears several. Mention you'd report the patterns you find.
Show a sample answerHide the sample answer
I'd first pull anything close to the timely filing limit, because those are about to become write-offs. Then high balances, then I'd batch by payer so one call to UnitedHealthcare covers ten claims instead of one. On my last team that batching took me from about 35 claims a day to 50.
A patient calls angry about a bill they think insurance should have paid. What do you do?
Why they ask
Some billing roles take patient calls, and US patients can be blunt about money.
How to answer
Verify identity, listen, explain the EOB in plain words (deductible, co-insurance), check for a billing error on your side, and offer a payment plan if the balance is correct. Stay calm and never argue about the insurer's decision.
What would you do if you noticed a coder kept using a code the notes didn't support?
Why they ask
Tests compliance instincts. Billing what wasn't documented can be fraud.
How to answer
Don't change codes yourself. Hold the claims, raise it with the coder or the coding lead with examples, and document the conversation. Show you understand the risk to the practice.
Remote work questions
How you'll work from Nigeria with a team elsewhere: hours, power, internet, communication.
How do you keep patient information safe when you work from home?
Why they ask
HIPAA is the first worry any US client has about offshore staff.
How to answer
Be concrete: a laptop only you use, screen lock, company VPN, no printing, no personal email or WhatsApp for patient data, a room where nobody can see the screen. Mention any HIPAA training you've done.
Show a sample answerHide the sample answer
I work on a laptop nobody else in the house touches, with the screen locking after two minutes. I only access charts through the company VPN and the EHR, I don't take screenshots, and I never discuss accounts on my phone. I did HIPAA training with my last employer and redo it every year.
Our shift is 8am to 4:30pm Eastern. How will you manage that from Lagos?
Why they ask
They've had offshore staff drop off at 9pm because of power or fatigue.
How to answer
Convert it yourself (2pm to 10:30pm WAT in the US winter, 1pm to 9:30pm in summer), then describe your setup and routine. Don't just say "I'm flexible".
Show a sample answerHide the sample answer
That's 2pm to 10:30pm here in the US winter and 1pm to 9:30pm in summer, and I've worked that pattern for two years. I have a 3.5kVA inverter with solar panels and a Spectranet router with MTN as backup on my phone. I sleep late morning and keep the afternoon clear.
How do you track your own work when your manager is six hours behind?
Why they ask
Remote billers have to be self-managing.
How to answer
Describe your daily log: claims worked, calls made with reference numbers, appeals sent, and a short end-of-shift note in Teams or Slack so the US team starts the morning knowing where things stand.
Remote interview tips
Test your headset on a real call before the interview. Many billing interviews include a mock insurer call, and a noisy line counts against you.
Keep a notepad with a few denial codes, Medicare's filing limit and your shift conversion (Eastern to WAT) in front of you. If they send an Excel test, it's usually an AR ageing sheet: practise pivot tables and conditional formatting the night before.
On camera, have a plain wall behind you and nobody walking past. US healthcare clients notice privacy before anything else.
Questions people ask
Do medical billing interviews include a test?
Often. Expect a short quiz on denial codes and claim forms, an Excel exercise, or a role-play call to an insurer. RCM firms almost always test; small practices sometimes skip it.
Will they ask about HIPAA?
Almost certainly. Be ready to explain how you protect patient data at home in practical terms, not just that you know HIPAA exists.
Can I pass a billing interview with no US experience?
Yes for entry roles like eligibility or AR follow-up, especially with a CPB or CMRS. Talk about any claims work you've done for HMOs in Nigeria and show you've studied the US claim cycle.
How long is the hiring process?
For offshore billing teams, usually one to three weeks: screen, skills test, team-lead interview. Direct hires by US practices can be faster, sometimes a single call.

Interview questions for roles close to medical billing specialist
- Medical Coder
A medical coder reads doctors' notes and converts every diagnosis and procedure into standard codes (ICD-10-CM, CPT, HCPCS) that insurers pay against. It is one of the most remote-friendly jobs in healthcare, but from Nigeria the honest route is a US credential like the CPC or CCS plus an offshore employer, because most US remote coding jobs only hire people living in the US.
- Health Data Analyst
A health data analyst turns hospital, insurance, programme or public-health data into answers: which clinics are missing immunisation targets, which patients are readmitted, where claims costs are rising. It works well remotely from Nigeria, especially for global health organisations using DHIS2, KoboToolbox and Power BI; US hospital and insurer analytics jobs exist too but are often limited to US residents.
- Accounts Receivable Specialist
An accounts receivable (AR) specialist sends a company's invoices, matches incoming payments to them and chases customers who pay late. Remote AR and credit control jobs for UK and US companies are open to Africans, though many offshore ads with published pay are limited to South Africa, so Nigerians should read the location line before applying.
- Virtual Assistant
A virtual assistant runs a client's admin from a distance: inbox, calendar, bookings, CRM updates, simple graphics and follow-ups. It is one of the most realistic remote jobs to land from Nigeria without a degree, but honest starting pay in 2026 agency ads is $6 to $7 an hour.
