So Your A/R Is a Mess, Now What?

September 11, 2026

You pull your aging report, and there it is: a wall of red stacked up past 90 days, some of it old enough to vote. Your stomach drops. Where do you even start?

First, breathe. A messy A/R isn't one problem; it's a collection of diagnosable symptoms. The billers who successfully dig themselves out don't start by frantically working claims; they start by figuring out why the hole got so deep in the first place. Let's walk through how we’d tackle it if we were sitting at your desk.

Why is your A/R a mess in the first place?

Aged accounts receivable doesn’t just appear out of nowhere. It's what builds up when an upstream leak goes unpatched. So before you start bailing, find out where the water's coming in. 

Start with the usual suspects: 

• Bad or incomplete patient demographics captured at the front desk

• Eligibility that never got verified, so the claim was dead on arrival

• Coding errors and missing modifiers that trigger predictable denials

• Claims going out the door too slowly and bumping into timely-filing limits

• Patient balances that nobody asked for at the point of service, quietly aging into never-never land

If you clean up the backlog without fixing the sources, you'll be right back here in a few months with a fresh wall of red. So we diagnose first, then treat.

Know your numbers: what does "good" even look like?

You can't fix what you can't measure, and you can't measure against an unknown target. Here are a few benchmarks worth checking out:

Days in A/R is the average number of days it takes to collect what you've billed. It's the most diagnostic number you have. Your days in A/R should stay under 50 at a minimum, with 30 to 40 days being the preferred range. Best-in-class billing teams push under 30.

Your denial rate is simply the share of your claims that get denied. The industry typically runs between 5% and 10%, with under 5% being optimal. If you're above that, your A/R problem is really a front-end problem wearing a disguise.

The net collection rate is the percentage of the money you were entitled to collect (after contractual adjustments) that you actually collected. How much did you get? You should aim for 95% or better. Anything lower means revenue is leaking through late filings, underpayments, or claims nobody followed up on.

Don't have these numbers at your fingertips right now? That itself is telling.

How do you actually clean up aged A/R?

Now we roll up our sleeves. Here's what we suggest:

1. Triage before you touch anything. Run your aging report and segment it in two ways: payer responsibility versus patient responsibility, then rank by balance size, timely filing or appeal deadlines, and collectability. You want your team’s effort on the highest-value, most-collectible dollars first. Don’t just work alphabetically and burn a whole morning on a $12 balance.

2. Find the denial patterns. Pull the oldest buckets and look for any repetition. The same missing modifier over and over? An eligibility issue tied to one payer? Coding errors clustered around one provider or one procedure? Patterns point to where to retrain staff, adjust a process, or tighten your claim edits so the leak stops.

3. Set up a focused cleanup team. Pull experienced billers off current-day charge entry and point them at aged claims only. How many people to assign depends entirely on the size of your total team and your backlog. They need a dedicated focus with clear daily targets (say, resolve $10K in over-90 A/R per day) and trackable progress everyone can see.

4. Rework denials the right way, for accuracy. "Work denials harder" is not helpful advice. The right move is to identify the denial reason first, then take the appropriate next step. Correct and resubmit if it's fixable, or appeal at the correct level with payer-specific language. Firing off blind appeals just generates more noise coming back at you.

Should you work claims from an aging report or a worklist?

Work from worklists, not a printed aging report. A worklist tracks when a claim was last touched and when the next follow-up is due, so nothing slips through the cracks and no two billers work the same claim. An aging report is a snapshot and it's technically stale the moment you print it. Claims resolve, balances shift, and now your team is calling payers about accounts that have already been paid. Whenever possible, work claims live from your system and look at the most current status. The report and a pack of highlighters feel productive, while the worklist actually is.

What's a zero-dollar remit, and why should you care?

Zero-dollar remittances should be prioritized because they always require action, not observation. Whether the balance needs to be transferred to patient responsibility, or a denial corrected or appealed, they signal that the claim cannot move forward until someone takes action. Until that happens, the account continues to age, and reimbursement remains at risk.

Confirm the deposit before you post

Make sure the money has actually landed in the bank account before you post the ERA. Posting first and confirming later, thinking you can "resolve" open A/R on your books without receiving payment, feels great until reconciliation day. Confirm the deposit, then post.

Should you resubmit all your old claims at once?

Tempting, isn't it? One big batch, blast them all back out, watch the A/R melt away. Please don't.

Mass-resubmitting old claims generates an avalanche of noise you then have to sift through: duplicate-claim denials, timely-filing rejections, and a fresh assortment of new denials. These often are on claims that were already paid or already resolved. You'll create more work than you clear. Old claims need to be reviewed and worked, not blasted back at payers. There's no real shortcut, just doing the work.

Don't forget the patient side of A/R

More of your revenue lives in patients' pockets than ever before, and that money is the hardest to collect once it ages. The best advice is to collect early and communicate clearly.

Nothing moves the needle more than collecting patient responsibility at the time of service. Full registration at scheduling lets you verify eligibility and benefits and tell the patient what they'll owe before they even walk in for their appointment. Communicate the financial policy clearly and proactively, including copays, deductibles, coinsurance, estimates, and any outstanding balance at every touchpoint:

• At scheduling: set the expectation that payment is due at the time of service.

• On reminder calls and texts: include the expected prepayment amount or a prepay link.

• At check-in: ask for payment before the appointment.

• At check-out: collect payment if not already done or confirm the next step.

Communication is what turns patient collections from an uncomfortable interaction into an expected part of the process. Clear expectations lead to better patient experience and stronger collections.

For balances that do go out, keep a structured follow-up cadence. Start with a friendly first statement, then a polite call or text, then a final notice at set intervals if necessary. Verify the address, phone, and email before you send anything. Offer online bill payment and no-interest payment plans. The easier you make it to pay, the more people pay. Consider a daily statement cycle so new balances go out the moment they become the patient's responsibility, instead of waiting for a monthly batch. This not only reduces your days in A/R, it also smooths out cash flow and distributes patient phone calls evenly throughout the month.

When should you write off a claim or send it to collections?

Not every dollar is worth chasing, and pretending otherwise just clogs your worklists. When the internal cost to collect exceeds what you're likely to recover, it's time to hand off or let go. A rough timeline many billers use:

• 0 - 30 days past due: Use simple in-house follow-up calls, reminders, and/or statements.

• 30 - 60 days: Continue in-house follow-up and begin to evaluate cost versus recovery. If in-house recovery looks unlikely, it’s time to consider outsourcing the collection. 

• 60 - 90+ days: Apply your written bad-debt policy and write off what's genuinely unrecoverable.

The critical word there is written. Have a bad-debt write-off policy signed off by ownership or partners. Write-offs are a deliberate business decision and not a judgment call made claim-by-claim. Caution: writing off in bulk to "reset" the aging report can be reasonable housekeeping. But resubmitting claims in bulk (see above) is not. Know which one you're doing.

"The health of your revenue cycle is a shared responsibility. No single department owns it. High-performing practices already know that A/R isn't a back-end problem. It's the outcome of timely, accurate handling at every step, from scheduling through resolution."

How do you keep your A/R from becoming a mess again?

Cleanup is a project. Staying clean is a habit. Build these habits into your routine:

• Review your numbers on a consistent rhythm. Days in A/R is typically a monthly review, a trend, not a daily heartbeat. Watch it month over month, alongside your percentage of A/R over 90 days and your denial and overturn rates.

• Bring the team in. Set clear goals and expectations, and then meet to review results. Share lessons learned so the team can continuously improve together. Celebrate the wins out loud, and when a goal gets missed, figure out together how to bridge the gap. Momentum is a team sport.

• Close the front-end leaks for good. Schedule quarterly coding and documentation reviews with your providers. Update fee schedules at least annually, and maintain accurate payer allowed-amounts per contract so underpayments don't go unnoticed. Whenever a denial spike reappears, take action to determine the root cause. Recurring denials are often a symptom of a process issue, payer change, or workflow breakdown. Addressing the underlying cause prevents repeat denials and protects future revenue.

• Write it down. Build (or sharpen) policies and procedures for each relevant department, then actually train them. Processes need to live in action in the real world, not only in your best biller's head.

The honest last word

At the end of the day, a messy A/R is rarely a billing team failure. It's an entire workflow or process that drifted. It could be a few front-end gaps, a follow-up process that leaned on stale reports, a denial pattern nobody had time to trace, or some combination of issues. Find the breakdowns, fix the root causes, and the optimal A/R results will follow.

That's also the hard part. Diagnosing your specific leaks, populating worklists that fit how your team actually works, building the SOPs, and running the backlog without dropping today's charges on the floor. It's exactly the kind of work our team at Open Practice has done from the inside, because many of us came in as billers ourselves. If you'd like an objective review of your aged A/R and the processes driving it, we can help identify root causes, prioritize opportunities, and develop a practical strategy for your team to implement.
