A write-off is a decision, not an outcome
There is a number on your balance sheet called accounts receivable. Some of it is money. The rest is a story about money.
Nobody ever decided which parts were which. It happened by not happening.
The quiet version of a decision
Here is how a receivable becomes uncollectible without anyone saying so.
A claim denies. Somebody means to rework it. The week gets busy. It ages 60 days, then 90. At 120 it moves into the bottom bucket of the aging report where nobody looks. At 180 it passes timely filing and becomes unappealable. It sits there for another year because deleting things feels like admitting something.
At no point did anyone decide to write it off. At no point did anyone decide to keep it either. It just kept showing up, month after month, making the A/R total slightly less true.
Multiply by four hundred claims and you have a balance sheet with a number on it that the practice owner believes and the bank will not.
What “truly uncollectible” means
Three tests, in order. A receivable fails any one of them and it is not an asset.
Past timely filing with no appeal on file. This is the hard one. Timely filing limits run from 90 days to a year depending on payer and state. Once the window closes on a claim that was never appealed, there is no mechanism left. It is not aggressive to write it off; it is aggressive to keep it.
No supporting documentation. A claim for a session with no note, no signature, or no matching authorization is not collectible even inside the window, because the first thing an appeal requires is the record. If the record does not exist, neither does the receivable.
Patient responsibility past the point of collection. A copay balance on a family that discharged fourteen months ago is not an asset. It is a hope with an invoice attached.
Everything that passes all three is a receivable. Everything else is a write-off that has not been booked.
The arithmetic
Illustrative arithmetic, not a client engagement.
The aging report says $364,000. The honest number is $263,000. The difference is not a loss you just took — it is a loss you took over the preceding eighteen months and never recorded.
That is the uncomfortable part of this work. Booking the write-off does not cost you the money. The money was already gone. Booking it just stops you from making decisions as though it were still there.
Why it matters before it matters
Most owners can carry an overstated A/R for years without consequence. The consequence arrives all at once, usually in one of three ways.
A lender asks for a receivables aging to support a line of credit and discounts everything over 90 days to zero. A buyer’s quality of earnings team does the same thing and takes it out of the purchase price. Or you make a hiring or distribution decision based on cash you thought was coming.
The third one is the most common and the least discussed, because it never gets attributed. Nobody says “we over-distributed in Q2 because A/R was overstated.” They say cash was tight.
The policy is one paragraph
You do not need a committee. You need a rule, written down once, applied every month at close.
Something like: any claim past timely filing with no appeal on file is written off at the next close. Any claim over 120 days with no documentation is written off at the next close. Patient balances over 180 days on discharged clients are written off at the next close. Anything written off and later collected is booked as recovery, not as a reversal.
That last line matters more than it looks. It means writing something off is not a prediction that you will never see the money. It is a statement that you are no longer counting on it. If it shows up, good — it shows up as a recovery, and everyone can see that it was a surprise.
Five checks you can run this week
1. Pull A/R over 180 days and count how many have an appeal on file. If the answer is “none,” that whole bucket is a write-off waiting to be booked.
2. Take ten claims at random from the 121-to-180 bucket and try to produce the session note and the authorization for each. The hit rate on that sample tells you what the bucket is worth.
3. Get your timely filing limits in one place, by payer. Most practices cannot produce this list, which is why claims pass the line without anyone noticing it happened.
4. Compare your reported A/R to the cash you actually collected in the following 90 days. Do this for a quarter that has fully run. The ratio is your real collectability, and it is the number a lender will use.
5. Write the policy paragraph and put a date on it. An unwritten write-off policy is the same as no policy, and the first person to enforce it without one gets accused of hiding something.
The number to actually track
A/R net of everything past timely filing with no appeal on file, and of everything without supporting documentation.
Pair it with the cash actually collected in the 90 days following a closed period’s A/R balance. That ratio is your real collectability.
A gross aging report is a balance sheet number that nobody outside the practice will accept at face value.
Where this sits
This is the eighth and last of the stages where ABA revenue leaves. It is where money that was collected goes back out, and where money that was never collectible finally gets recognised.
Booking the write-off does not cost you the money. The money was already gone. It stops you making decisions as though it were still there.
A Leak Map Assessment measures all eight — the reservoir, authorization burn, cancellations, session conversion, conversion to billed, clean claims, rate integrity and recoupments. A claims audit is a different instrument. It starts once a session has been converted and billed, and reconciles the back half of the cycle to cash.
Aimline closes the books, oversees the revenue cycle, and sits in the CFO seat for ABA practices. We run claims audits scoped to a payer book, and Leak Map Assessments that measure the full cycle — three weeks, $7,500 fixed. Either one gives us a verified number to run oversight against, and the report is yours whether or not you engage us to fix what it finds.
