B2 Bulletin

Most practices know the 120-day warning: the older a claim gets, the harder it is to collect. That part is true. But somewhere along the way, a more damaging assumption took root, that once a claim crosses the one-year mark, it’s automatically uncollectible and should be written off.
 
So that’s exactly what happens. Automated rules in the practice management system flag aged claims, batch them into a bad-debt adjustment, and clear them off the AR report. The aging number looks healthier. Everyone moves on.
 
The problem is that a meaningful share of those write-offs were still collectible. The automation didn’t check. And every dollar written off that didn’t need to be is real revenue, converted into inflated bad debt, gone for good.
 
Timely filing is not measured the way most automation assumes
 
Here’s the core error. Many automated write-off rules calculate timely filing from the date of service. That’s the intuitive assumption, and for an original claim submission it’s often correct. But it’s not the whole picture.
 
Timely filing limits frequently reset or recalculate based on the most recent payer action, not the original date of service. Consider:
 
• A claim denied and resubmitted may have its timely filing window measured from the date of the last denial or remittance, not the original visit.
• Appeals carry their own separate deadlines, often 60, 90, or 180 days from the date of the denial, completely independent of the original filing limit.
• A payer’s own processing error, retroactive eligibility, or coordination-of-benefits delay can extend or reset the clock.
• Secondary claims have filing windows that run from the primary payer’s remittance date, which can fall well after the date of service.
 
An automated rule that only looks at date of service sees a claim that’s 400 days old and writes it off. A human looking at the same claim sees a denial issued 45 days ago with active appeal rights and a timely-filing clock that started at the denial, not the visit. Same claim. Opposite outcome.
 
Appeal rights don’t expire just because the claim is old
 
A claim being old is not the same as a claim being final. If a denial was issued recently, the appeal window may still be wide open even if the date of service is more than a year back. Reasons a one-year-old claim may still be very much alive include:
 
• A recent denial or partial payment that reopened the timely filing or appeal window.
• A documented payer error, where many payers will reprocess regardless of age.
• Proof of timely original submission, which overrides the filing limit in most payer policies when documented correctly.
• Continuation of an open appeal or reconsideration that was already in progress.
 
None of this gets evaluated when the write-off is automatic. The system doesn’t read the remittance history. It doesn’t check for active appeal rights. It just sees an age and applies a rule.
 
Automation is a tool, not a decision-maker
 
This isn’t an argument against automation. Automated aging reports, denial work queues, and follow-up triggers are essential. The danger is using automation to decide what’s uncollectible rather than to flag what needs review.
 
A healthy AR process draws a clear line: automation surfaces the claim, a knowledgeable person decides its fate. Before any aged claim is written off, someone should confirm:
 
1. What was the last payer action, and when? (Not just the date of service.)
2. Is there an active appeal right, and what is its actual deadline?
3. Do we have proof of timely original filing?
4. Was there a payer error or eligibility issue that resets the clock?
5. Is this truly final, or just old?
 
A claim only becomes bad debt when the answer to “is anything still collectible here” is genuinely no. Age alone never answers that question.
 
What this costs, and what it’s worth
 
When practices write off collectible claims automatically, two things happen at once. Real revenue disappears, and the bad-debt figure inflates, distorting the financial picture and masking the fact that the AR process itself is leaking money. Leadership sees rising bad debt and assumes it’s a payer or patient problem, when often it’s a workflow problem.
 
The fix doesn’t require new software. It requires the discipline to review before writing off, the knowledge to recalculate timely filing from the right date, and the diligence to catch every denial that’s still within its window. That’s slower than a batch write-off. It’s also where the recoverable dollars are.
 
Before you write off another aged claim, ask one question: is this claim final, or just old? The difference is real money.
 
At B2, we believe every legitimate dollar a practice has earned is worth pursuing with diligence and integrity. Driven by Faith. Built on Integrity. Focused on Results.
