Most practices don't lose money on billing all at once. It leaks out a few claims at a time: a denial nobody reworked, a charge that was never entered, a patient balance that quietly went to write-off. Each one looks small. Over a year they add up to revenue you earned but never collected.
The good news is that the leaks show up in your numbers long before they show up in your bank account. Here are five warning signs to look for, and what to do about each one.
1. Days in A/R keep creeping up
Days in accounts receivable measures how long, on average, it takes to get paid after you provide a service. Many independent practices aim to keep it under 40 days, though the right target depends on your specialty and payer mix.
If the number rises month after month, claims are getting stuck somewhere: submitted late, rejected at the clearinghouse, or sitting with a payer without anyone following up. Look at your aging report by bucket. Money that moves past 90 days becomes much harder to collect, and some of it will run into the payer's timely filing limit.
What to do: review aging weekly, not monthly, and assign every open claim over 30 days to a named person with a follow-up date.
2. Your denial rate is above 5 to 10 percent
Every denied claim costs staff time to research, correct and resubmit, and many are never reworked at all. A healthy practice typically sees a small single-digit percentage of claims denied on first submission.
A higher rate usually points to fixable front-end problems: eligibility that wasn't verified, missing prior authorizations, demographic errors, or coding and modifier mistakes.
What to do: group denials by reason code every month. The top three reasons almost always account for most of the volume, and each one has a process fix.
3. Write-offs and adjustments are growing
Contractual adjustments are normal. Write-offs for timely filing, missing authorizations or "small balance" clean-ups are not, because they represent revenue that was collectible.
What to do: separate contractual adjustments from avoidable write-offs in your reports, and require a reason code and approval for anything that isn't contractual.
4. Charges are entered late, or not at all
Charge lag is the time between the visit and the claim going out. When notes are signed late or charges wait in a queue, every downstream step slows down. Worse, some encounters never get billed, especially in-office procedures, injections and supplies.
What to do: reconcile your schedule against submitted charges every day, and track charge lag as a standing metric. A target of one to two business days is realistic for most practices.
5. Patient balances go uncollected
As deductibles have grown, a larger share of revenue now comes from patients. If you don't estimate and collect at the time of service, those balances are far harder to collect later.
What to do: verify benefits before the visit, give patients a clear estimate, collect copays and known balances at check-in, and send simple, easy-to-pay statements.
