The three phases of the revenue cycle
Most denials originate in the front end and are paid for in the back end. A biller who only works the back end is permanently cleaning up someone else’s mistakes. The good ones push fixes upstream.
A day in the life
Morning. Check overnight clearinghouse reports and work every 999 and 277CA rejection before anything else — they are the cheapest problems available and they expire. Then run eligibility on tomorrow’s schedule and flag coverage problems for the front desk to call today. Midday. Enter charges for yesterday’s completed visits. Reconcile the schedule against charges so nothing was seen without a charge — the unbilled encounter report is the single most valuable daily number. Run the scrubber, clear the edits, submit the batch. Afternoon. Post 835s. Auto-posting handles most lines; the exception queue gets a human — unmatched claims, PLB takebacks, interest, secondary transfers. Confirm every deposit ties to its remittance by TRN. Late afternoon. Work the denial queue by CARC group. Corrected claims out, appeals drafted, root causes tagged. Then patient calls: statements, balances, payment plans, and the occasional refund. Weekly. AR aging review. Credit balance report. Credentialing grid update. Follow-up calls on payer applications that have gone quiet.Coder vs biller
In most small practices these are one person, and the clinician codes their own encounters. That is normal. What matters structurally is that the MSA is clear that coding responsibility rests with the PC — see What an MSO can and can’t do.
What separates a good biller from an adequate one
An adequate biller submits claims and posts payments. A good one: Works rejections same-day. Not weekly. A rejection queue that ages is revenue quietly running toward timely filing limits. Tags root causes, not just fixes. “Fixed and resubmitted” tells you nothing. “Authorization obtained but never entered into the PM field” tells you what to change. Pushes fixes upstream. The best billers spend part of their time changing the front desk’s workflow, because that is where the money actually leaks. Reads contracts. Knows each payer’s timely filing limit, appeal deadline, and contracted rates, and notices when a payment is short. Catches underpayments. Compares allowed amounts against the contracted fee schedule. Systematic underpayment is invisible unless someone looks. Knows the difference between a rejection and a denial. And doesn’t waste appeals on claims that were never adjudicated. Escalates well. Knows when to call provider relations, when to invoke a prompt-pay statute, and when a claim needs a supervisor rather than another portal submission.The metrics a biller owns
Net collection rate is the one that catches quiet leakage. A practice can have an excellent clean claim rate and still be at 88% net collection because it writes off patient balances, misses timely filing, or never appeals underpayments.
How many billers do you need
Highly specialty-dependent — a high-volume, low-complexity practice generates far more claims per clinician than a surgical one. Directional heuristics:
Better than any ratio: measure the work. If claims go out same-day, rejections are worked same-day, the denial queue has nothing over 14 days, and AR is stable, you have enough billers. If any of those slips, you don’t.
