Why claims sit at 90 days, and what actually moves them

The four reasons, in the order they cost you money

Nothing on an aged accounts receivable report is intellectually difficult. It is difficult because the person who could fix it is at the front desk answering a phone. But the pile is not homogeneous, and treating it as one pile is why most clean-up projects stall in week three.

1. It was never worked at all

The largest bucket in almost every practice we have looked at. The claim went out, a denial or a partial payment came back, and nobody opened it. It ages quietly because nothing on the worklist screams. This bucket is pure labour: it needs somebody to call, not somebody to think.

2. It was worked once, then abandoned

Somebody called, was told the claim was in process, made a note, and never went back. The payer reference number is often sitting in the account. These are the cheapest recoveries available because half the work is already done, and they are also where CO-29 timely filing denials come from — every one of those is a claim that somebody already touched.

3. It is stuck behind something structural

A lapsed enrolment, a stale coordination of benefits record, a provider whose revalidation was missed. Nothing on these claims will pay until the underlying record is corrected, and calling on them individually is wasted effort. CO-B7 and CO-22 both live here. Fix the record, then release the batch.

4. It is genuinely uncollectable

Filed too late with no proof of timely submission, or a service the plan never covered. The honest answer is to write it off and stop paying people to look at it. A practice that cannot bring itself to write off dead paper ends up paying more in labour than the balance was worth.

How to sort the pile in an afternoon

Pull the report and group by denial code rather than by payer or by age. Codes tell you which bucket a claim is in; age only tells you how long it has been there. CO-16 and CO-197 are bucket one and two. CO-B7 and CO-22 are bucket three. CO-29 without a clearinghouse acceptance report is bucket four.

Then work from the difficult end. Every instinct says to start with the easy claims because the count drops quickly, and every instinct is wrong: the easy ones will still be collectable next month, and the hard ones will not.

What a seat changes

It does not change the rules and it does not find money that was never there. What it changes is that somebody is on the queue every working day, calling, logging the reference number, and writing down what happens next — which is the entire job and the reason the pile exists.
