Hiring for this seat goes wrong in a familiar way, so the questions below run in the order a good interview runs. What separates a candidate who has worked an aging report from one who has only posted payments comes first, because it surfaces within five minutes and it decides everything after. Reading a denial off its CARC and RARC codes is the second test, since a remittance line either turns into a next action or it sits. Appeal and reconsideration steps follow, and a serious candidate will describe a packet, a deadline and the signature that has to be on it. Whether an aging bucket gets worked from the top down is a question with a wrong answer, which makes it a fast way to separate habit from judgment. Payment posting accuracy and the patient balance phone calls are the last practical tests, since a contractual adjustment keyed as a bad-debt write-off hides money and a clumsy call loses it. Scoring belongs beside those tests rather than after them. Where the interview facts on this page come from, and which of them Honest Taskers publishes rather than implies, closes the page out.
An accounts receivable specialist who has worked an aging report talks about payers by name, and one who has only posted payments talks about batches. That single difference does more sorting than a resume will. Posting is a keying job with a reconciliation step bolted to the end of it, and it rewards accuracy. Working receivables is a decision job, because every open claim on that report is a small argument with a payer that somebody has to win, escalate or write off.
Three opening questions carry most of the weight. Which payer gave them the most trouble in the last role, and what was the pattern behind it? A useful answer names a plan, a specific claim edit and the fix that finally cleared it. Next comes the oldest open claim on their last aging report and why it sat as long as it did, which tells you whether anybody was allowed to close things out. The third question asks how they knew a claim had been received at all, and a person who has done this work reaches for the clearinghouse acceptance report and the 277CA acknowledgement rather than a shrug.
Vocabulary gives experience away quickly. Somebody who has lived in this queue says 837P, 835, secondary billing, takeback and recoupment without stopping to translate, and they know the CMS-1500 is the professional claim while the UB-04 belongs to facility billing. A candidate who only ever posted will describe the same objects as reports, files and adjustments.
Two follow-ups make the difference concrete. Ask what they did when a payer paid at the wrong contracted rate, and listen for whether the fee schedule got checked against the contract or the underpayment got posted and forgotten. Then ask about the last claim they chose not to pursue, since knowing when to stop is part of the job and a candidate with no such example has been working somebody else's list without authority.
Purchase model belongs in this conversation too. Honest Taskers places these professionals as staffing at $10.00 to $12.65 an hour depending on the role, candidate background, schedule and location, so your team keeps the follow-up strategy and the payer relationships. An outsourced revenue cycle firm buys the opposite arrangement, and Transcure publishes 3% to 5% of monthly collections for that model. Neither is better in the abstract, and the interview only makes sense once you know which one you're running. Managers hiring across the wider billing seat will find overlapping ground in our medical billing interview questions.
An accounts receivable specialist reads a denial by pairing the claim adjustment reason code with the remittance advice remark code on the 835, then turning that pair into one of three moves, which are rebill, appeal or adjust. The reason code says what the payer decided, and the remark code says why. Neither one tells you what to do next, and the whole skill sits in that gap.
Run this as a live exercise instead of a question. Print one real remittance line from your own system, hand it across the table, and ask what happens next and who has to touch it. Silence is fine for ten seconds. Guessing is not, and a candidate who invents an answer here will invent one on your aging report too.
Five denial families cover most of what lands in a practice queue, and each one has a different correct response.
Rejection and denial are different objects, and plenty of candidates use the words interchangeably. A rejection comes back from the clearinghouse or the payer's front end before adjudication ever happens, so nothing was decided and the claim never entered the payer's system. Adjudication produces the denial instead, on the 835, with a reason code attached and an appeal clock already running. Denial management as a discipline starts at that line, and a person who can't separate the two will report a clean claim rate that isn't real.
One question worth keeping for the end of this block asks where they'd go to check a rule they weren't sure about. The Centers for Medicare and Medicaid Services publishes the Medicare coding and billing guidance that sits behind Medicare remittance advice, and a candidate who names a source rather than a coworker is telling you how they'll behave when nobody is watching. Practices working the upstream side of the same problem can read our guide on how to reduce claim denials.
A strong candidate describes an appeal as a packet with a deadline attached, never as a letter. Ask them to walk you through the last one they built, start to finish, and count how many of the pieces they name without prompting. A corrected claim, or a clean copy of the original. The remittance showing the denial itself. Whichever operative note, office note or physician order supports the service that got refused. The payer's own coverage policy, quoted back at it. A cover letter stating what's in dispute in two sentences and asking for one specific outcome.
Government and commercial work run on different rails, and a candidate should know which rail they've been on. Medicare's first level is a redetermination filed with the Medicare Administrative Contractor, and the second is a reconsideration handled by a Qualified Independent Contractor. Commercial plans run their own sequence, which in most contracts starts with an informal reconsideration or claim review before a formal appeal, with the steps written into the plan's provider manual rather than into federal rules. A person who has only ever called a payer's phone line has not built an appeal.
Deadlines are where this question gets dangerous, so handle it carefully. Filing windows and appeal windows vary by payer, by plan and by your own contract, which makes them a fact your practice owns rather than something an article can hand you. What you're testing is whether the candidate knows the deadline is contract-specific and knows where to look it up, not whether they can recite a number that may be wrong for your book of business. Somebody who quotes one confidently for every payer is guessing.
Two more questions round the block out. Ask what they do when an appeal is denied a second time, and listen for whether the answer includes a decision to stop, since endless resubmission is a cost dressed up as diligence. Then ask for an appeal they won that they expected to lose, and what changed the outcome, because the answer turns out to be a document somebody else didn't bother to pull. The same workflow gets traced from the assistant's side of the desk in our walkthrough of denial management.
Compliance sits underneath all of it. An appeal packet moves protected health information, so the arrangement around the person matters as much as the packet does. Honest Taskers puts its professionals through quarterly HIPAA training and quarterly data privacy training led by a dedicated HIPAA compliance officer, signs a Business Associate Agreement with healthcare clients when the professional will access protected health information, and describes its security environment as SOC 2 audit ready. No individual holds HIPAA compliance as a personal status, because compliance sits with the covered entity and its business associates, so treat the training and the signed agreement as separate things doing separate jobs.
No, and a candidate who says yes has told you they've been handed a list rather than a method. Top-to-bottom feels orderly and it wastes the month. The 31-to-60 bucket holds claims that a single phone call still fixes, while parts of the 120-plus bucket are already past every filing window that mattered. Sorting by row order treats those as the same work.
Push for the sort they'd apply on day one. Dollar value is the obvious axis and the least interesting, since a good specialist adds three more. Deadline proximity comes first, because a claim eleven days from a timely filing cliff outranks a larger claim with ninety days left on it. Payer clustering comes second, since twenty claims sitting behind one credentialing gap or one bad payer identification number clear together in a single call. Root cause comes third, and it's the one that separates a specialist from a caller.
Root cause is worth its own question. Ask what the last systemic problem they found was, how they found it, and who they told. An honest answer sounds specific and slightly annoyed, such as a front desk keying the subscriber identification number without the alpha prefix, a registration flow that never captured the secondary plan, an eligibility check nobody ran on Medicare Advantage patients, or a charge entry template that kept dropping a modifier. A vague answer about following up more consistently means they worked the symptom every month and never went upstream.
Small balances deserve one direct question, since practices disagree about them and the disagreement is legitimate. Ask what they'd do with two hundred claims under fifteen dollars each, and there's no single right answer. What you're listening for is whether they'd propose a rule, take it to you for approval and then apply it consistently, or whether they'd quietly write them off, quietly chase them all, or leave them sitting so the aging report keeps looking worse than the practice's true position.
Cadence closes this section. A candidate who says they touch each open claim on a set rhythm, log every payer contact with a call reference number and a name, and never call a payer twice without reading the last note first has described a workable system. Anyone who describes the aging report as something they clear rather than something they work is describing a month-end panic.
Test posting with a real explanation of benefits and test the phone call with a role play, because both skills fail quietly rather than loudly. Hand over one remittance with a contractual adjustment, a patient responsibility amount and a sequestration reduction on it, and ask them to talk through every line as they'd key it. Watch for the adjustment. Keying a contractual write-down as a bad-debt write-off buries the difference between what a payer refused and what a patient owes, and a month of that corrupts every report you'd use to make a decision.
Reconciliation is the second half of the same test. A person who has posted properly will describe balancing the batch to the deposit before closing it, checking that the 835 total matches what hit the bank, and flagging the unapplied cash rather than parking it somewhere convenient. Ask what they did the last time a batch didn't balance. The answer either contains a search or it contains a plug, and a plug is disqualifying.
Patient balance calls need a role play with a real script. Play a patient who has just received a statement for a deductible they thought was covered, get audibly frustrated, and then say you can't pay all of it this month. Three things are worth marking. Whether they explain the deductible in plain language without reading the remittance codes aloud, whether they stay inside your written financial policy instead of inventing a discount on the call, and whether they hand the clinical question back to your staff when the patient asks whether the visit was medically necessary at all.
That last boundary is not negotiable. Honest Taskers professionals do administrative and clinically adjacent work, never clinical advice and never clinical decisions, and the talent pool including licensed nurses and physicians describes recruiting rather than scope. A patient asking whether a procedure was medically warranted gets a warm handoff to your clinical team, not an opinion from the person collecting the balance.
Score every answer on the same short scale so two interviewers land in the same place.
Weight the scale toward the work your practice has in front of it. A practice drowning in denials should weight the remittance-reading and appeal blocks heaviest, while a practice with clean claims and a bloated patient ledger should weight posting accuracy and the balance call. Write the weighting down before the first interview, because deciding it afterwards is how a likeable candidate beats a capable one.

One structural question belongs at the end of every interview, and it's the cheapest test on this page. Ask what they'd need from your practice in week one to do the job well. A candidate who asks for payer portal logins, the fee schedule, the financial policy and a named person to escalate to has run this play before.
Honest Taskers' hourly range, staffing model, quarterly HIPAA and data privacy training, dedicated compliance officer, Business Associate Agreement practice and SOC 2 audit-ready posture come from the company's own published service terms and compliance materials (Honest Taskers, 2026), as does the scope boundary that keeps its professionals on administrative and clinically adjacent work. Transcure's 3% to 5% of monthly collections is that company's own published pricing for outsourced revenue cycle work. Claim adjustment reason codes, remittance advice remark codes, the 835 remittance advice, the 837P claim, the 277CA acknowledgement, the CMS-1500 and the UB-04 are standard transactions and forms rather than anybody's proprietary vocabulary, and the Medicare rules behind them come from the Centers for Medicare and Medicaid Services, whose "Medicare Claims Processing Manual" governs the redetermination and reconsideration levels named above. AAPC, the body behind the Certified Professional Coder credential, publishes the coding certification framework a hiring manager can check a candidate's credential against, and the Bureau of Labor Statistics covers this occupation inside its financial clerks group. No denial rate, days-in-accounts-receivable figure, clean claim rate, collection percentage or appeal success rate appears anywhere above, because every one of those belongs to a single practice's own data and its own payer mix, and a number borrowed from somewhere else would make a hiring decision worse rather than better. Filing and appeal deadlines are contract-specific for the same reason.
