Chiropractic accounts receivable recovery
Chiropractic Accounts Receivable: How to Recover the Money You’re Owed
Aging AR isn’t lost money. It’s unworked money. Here’s how the aging buckets really work, why claims quietly stall, and how a dedicated coordinator turns old claims back into deposits.
What AR is
Your accounts receivable is money you’ve already earned, and the older it gets, the harder it is to collect.
Accounts receivable (AR) is the balance owed to your practice for care you’ve already delivered: claims sitting with insurers and balances sitting with patients, waiting to be paid. Every one of those dollars is revenue you’ve earned and not yet received. The problem isn’t that the money doesn’t exist; it’s that aging AR is the single easiest line for a busy practice to neglect, because nobody is paid extra to chase it.
And it decays. A claim worked at 30 days usually pays. The same claim ignored until 120 days runs into appeal deadlines, timely-filing limits, and payer reps who have no memory of it. This guide walks through how the aging buckets work, why claims stall in each one, and how a dedicated coordinator works AR down to recover money a stretched-thin front desk leaves behind. If you’d rather hand the whole problem to a specialist, that’s exactly what our chiropractic billing service does, on aged claims as well as new ones.
The line nobody owns: a denied CMT claim that needs an AT modifier, a balance that bounced for missing information (CO-16), a secondary claim never filed after the primary paid: each one sits in the aging report quietly aging out of the timely-filing window until it’s a write-off instead of a deposit.
Aging buckets
How the AR aging buckets work, and why each one matters.
Every practice-management system sorts unpaid balances into aging buckets by how long they’ve gone unpaid. The buckets aren’t just a report. They’re a clock. The further right a balance drifts, the lower the odds it ever gets collected, and the harder the recovery work becomes.
Recently submitted, awaiting payment
Claims here are normal. This is the time it takes a clean claim to adjudicate and pay. The goal is to keep as much of your AR as possible in this bucket, which means claims have to go out fast and clean the first time.
The work: confirm clean claims went out, watch for early rejections, and make sure nothing has silently failed to transmit from your EHR.
Should have paid, needs a nudge
Most payers should have responded by now. A balance still open at 31 to 60 days usually means a denial that wasn’t worked, a claim that needs a status check, or a request for information sitting unanswered.
The work: this is the highest-yield bucket. A denial caught and reworked here still has every appeal and refiling option open to it.
Aging, and appeal clocks are running
Balances here are at real risk. Appeal deadlines on denied claims are often measured from the date of the remittance, and many sit in the 30-to-90-day range. A claim ignored until now may already have a closing window.
The work: triage by dollar value and deadline, file appeals before they expire, and escalate claims the payer keeps stalling.
Old, hard, and aging toward write-off
This is where revenue goes to die. Claims this old run into timely-filing limits (CO-29), exhausted appeals, and patient balances that have gone cold. It’s the hardest money to recover, and the bucket a busy in-house biller never gets back to.
The work: aggressive, claim-by-claim recovery: refiling with proof of timely filing where it exists, appealing on the merits, and working patient balances before they’re lost for good.
A healthy practice keeps the large majority of its AR in the first two buckets. When the 91+ bucket swells, it’s almost never a payer problem. It’s a capacity problem. Nobody had the hours to work the claims down before they aged out.
Why claims stall
The five reasons chiropractic claims quietly stall in AR.
Aging AR is rarely one big failure. It’s the accumulation of small, fixable stalls, each one a claim that needed ten minutes of attention and never got it. These are the five we see most often when we take over a practice’s aged receivables.
Denials never reworked
A Medicare CMT claim denied for a missing AT modifier, or a service flagged as not medically necessary, comes back and simply sits. Nobody adds the modifier, fixes the documentation, and refiles.
Information requests ignored
The payer asks for the initial treatment date, records, or a corrected field. The request lands in a queue nobody works, and the claim ages while it waits for a five-minute reply.
Diagnosis mismatches
The M99.0x subluxation primary and the region billed disagree, or a pointer is wrong. The claim denies, and correcting and resubmitting it is exactly the kind of detail that slips when the desk is busy.
Secondary claims never filed
The primary pays, but the secondary or tertiary claim (and the patient’s remaining balance) is never billed. That residual revenue sits unclaimed in AR indefinitely.
Patient responsibility goes cold
Copays, deductibles, and coinsurance that aren’t statemented promptly get harder to collect every month. A balance billed at 30 days pays; the same balance at 120 days often doesn’t.
Timely-filing windows blown
The most painful one: a valid claim that was simply never filed, or never refiled, before the payer’s deadline. Once CO-29 lands, the money is usually gone for good.
Timely filing
CO-29 is the one denial you can’t appeal your way out of.
Every payer sets a timely-filing limit: the window, measured from the date of service, in which a claim must first be received. Miss it and the claim is denied CO-29, and unlike a coding error, there’s usually no fixing it after the fact. The work is the only thing that prevents it.
Limits vary widely by payer (some windows are short, others longer), and they’re unforgiving. A claim that bounced once and went back into the aging report can quietly cross its deadline while it waits to be reworked. The only defense is to keep the 61-to-90 and 91+ buckets actively worked, refile promptly, and keep proof of the original timely submission so a wrongly applied CO-29 can be overturned.
This is why “we’ll get to it” is the most expensive sentence in a billing office. A claim in the aging report has a clock on it, and the only thing that stops the clock is someone actually working it. That’s the job a dedicated coordinator owns, every bucket, every week.
Our AR process
We don’t just bill new claims. We work the old ones first.
When a practice switches to ACB, the aged AR doesn’t get abandoned in the changeover. It’s the first thing your coordinator attacks. We pull the full aging report, triage every open balance by dollar value and deadline, and work the buckets in the order that recovers the most money before it ages out.
Denied claims get the actual fix (the missing AT modifier added, the M99.0x diagnosis order corrected, the CO-16 information request answered), then refiled or appealed. Secondary and tertiary claims that were never filed get filed. Patient balances get statemented. And we keep working the same claims, not a rotating queue, because a dedicated coordinator who knows your account chases a stalled claim a call center never circles back to.
Prevention
The cheapest AR to recover is the AR that never ages.
Working aged claims recovers money that’s already at risk. The bigger win is keeping claims out of the danger buckets in the first place, and that comes from getting the front end right, every time, so fewer claims ever stall.
Scrub before submission, not after denial
- The AT modifier on active-care CMT (98940 to 98942) and the GA modifier where an ABN is on file
- The M99.0x subluxation as primary, matched to the region, with M54.x in support
- Modifiers 25 and 59 applied where a separate E/M or distinct service is documented
- The initial treatment date and required fields present, so nothing bounces CO-16
Work the buckets on a schedule
- Status-check claims as they cross 30 days, before they drift into the warning zone
- Rework denials in the 31 to 60 bucket while every appeal option is still open
- Triage the 61 to 90 and 91+ buckets by deadline so nothing ages into CO-29
- Statement patient balances promptly, while they’re still warm
Many of our clients run multi-specialty centers, so the same coordinator keeps this rhythm across the chiropractic, therapy (97110, 97112, 97140), massage, acupuncture, and nurse-practitioner lines billed under one roof. Tightening the front end is also where the consultative work lives: the same review that prevents denials catches undercharged visits and codes left off the claim, a big part of why ACB clients have seen collections rise roughly 20% on average after the switch.
Proof
Cleaning up AR is the first thing clients notice.
“ACB has been instrumental in cleaning up our accounts receivable, helping us transition between software, and staying on top of all our billing. Knowledgeable, and most importantly, effective.”
“I used to spend a lot of time calling insurance companies when claims weren’t paid. Now they’re part of my team, so I can focus on patient care. Highly recommend.”
“In practice over 30 years, I have never found a more professional, knowledgeable company. I have a dedicated person accessible at all times, and they’re compatible with my EHR so I have no extra steps.”
Pricing
Aged-AR cleanup is included, not a separate project fee.
Some billers charge a premium to work your old receivables on top of their regular rate. We don’t. Working your aging report (reworking denials, filing missing secondaries, beating timely-filing limits, statementing patient balances) is part of the standard service, covered by one performance fee: 7% of net collections, or a $1,500/month minimum, whichever is greater. All-inclusive, month-to-month, no contract, no setup charge. The full breakdown and a live calculator are on our pricing page.
Why it’s aligned: we’re paid on net collections, so working your aged AR down is exactly what our fee is designed to reward. When an old claim that would have been written off finally pays, you keep most of it, and we both win. Compare that against what in-house really costs in our cost guide.
FAQ
Accounts receivable, answered.
AR is usually sorted into aging buckets: 0 to 30, 31 to 60, 61 to 90, and 91+ days from the date the balance was billed. Balances in the first two buckets are normal and very collectible. Once a balance crosses 90 days it’s considered old AR: appeal windows are closing, timely-filing limits loom, and the odds of collecting drop. A swelling 91+ bucket is the clearest sign claims aren’t being worked.
Often, yes, if the timely-filing window is still open or you have proof the claim was originally filed on time. Many aged denials are fixable: a missing AT modifier added to a Medicare CMT claim, a corrected M99.0x diagnosis order, an answered CO-16 information request, or a never-filed secondary claim. The exception is CO-29 (timely filing) on a claim that genuinely missed its deadline, which is usually unrecoverable. That’s why working old AR quickly matters.
Every payer sets a deadline, measured from the date of service, by which a claim must first be received. The window varies widely by payer. Miss it and the claim is denied CO-29, and unlike a coding error, a true timely-filing denial usually can’t be appealed. The defense is to file clean the first time, rework denials promptly, and keep proof of the original submission so a wrongly applied CO-29 can be overturned.
Both. Your dedicated coordinator works your outstanding accounts receivable alongside new claims: pulling the aging report, triaging open balances by value and deadline, reworking and refiling denials, filing missing secondaries, and statementing patient balances. The aged AR isn’t abandoned in the handoff; it’s the first thing we attack, so the switch often recovers money rather than leaving it behind.
No. Working your aging report is part of the standard service, covered by one all-inclusive fee (7% of net collections, or a $1,500/month minimum, whichever is greater), month-to-month with no contract and no setup charge. Because we’re paid on what’s actually collected, recovering your aged AR is exactly what the fee is built to reward. See the full breakdown on our pricing page.
