The cheapest revenue in your clinic is already in your aging report
Every owner I talk to wants the same thing: more revenue. And almost every one of them reaches for the same lever first: more referrals, more marketing, another provider. Those are real levers. They’re also the most expensive ones you have.
The cheapest revenue in your clinic is money you have already earned and simply haven’t collected yet. It’s sitting in your accounts-receivable aging report right now. No new patient, no new referral source, no new hire required. Just work that’s already been done and billed.
Read your aging report like an operator
Pull your AR aged by bucket: 0–30, 31–60, 61–90, and 90+ days. Don’t look at the total. Look at the shape. Two clinics with the same total AR can be in completely different health. One is 80% in the 0–30 bucket and collecting fine. The other is 40% past 90 days and quietly writing off money every month it doesn’t act.
Three numbers tell you almost everything:
- Days in AR (DSO). How long, on average, it takes to get paid. Under ~35 days is healthy for outpatient PT; north of 50 is a leak.
- Percentage over 90 days. This is your danger bucket. The industry rule of thumb is to keep it under 15–20% of total AR. Above that, you’re losing dollars to timely-filing limits and payer fatigue.
- Denial rate. Denials that never get reworked become write-offs. A denied claim is not a dead claim, but only if someone touches it before the window closes.
Then work it in the right order
Not all aged dollars are equal. Triaged the way an operator would, the priority is:
- Big-dollar claims approaching a filing deadline. These are the ones you can still save and can least afford to lose. Time-sensitive and high-value, so work them today.
- Denials with a clear, fixable reason. Wrong code, missing auth, eligibility mismatch. Cheap to rework, high hit rate.
- Patient-responsibility balances that have aged because no one sent the second statement.
What you should not do is work the aging report top-to-bottom by patient name, which is how most front desks do it when it’s slow. That treats a $40 copay the same as an $1,800 claim two weeks from timely-filing death.
The honest part
Some of that aged money is genuinely gone. A claim 240 days out with no filing exception isn’t coming back, and pretending otherwise just wastes a biller’s afternoon. The skill isn’t chasing everything. It’s knowing which dollars are still recoverable and going after those first. Recovering 60% of what’s actually collectible beats chasing 100% of a number that includes ghosts.
That’s the whole game with AR: it’s not glamorous, it doesn’t require growth, and it’s the highest-return hour your front office will spend this week.
