Every practice has a number they’d rather not look at. It sits in the billing software, quietly growing. Some of those claims are a few weeks old. Some are a few months old. A few have been sitting there so long that nobody’s quite sure what to do with them anymore.
That number is your accounts receivable and if it’s getting bigger instead of smaller, you have an AR problem.
AR Recovery in Medical Billing is the process of going back through unpaid, denied, or underpaid claims and actually collecting what you’re owed. It sounds straightforward. In reality, one of the biggest missed areas and most cost-effective aspects of a medical practice is. This guide provides a clear explanation of what AR recovery is, how it works, how a healthy AR differs from an unhealthy one and what you can do right now to start reducing your AR
What Does AR Actually Mean in Medical Billing?
AR stands for accounts receivable. The total amount of money owed to your practice for services already rendered but not yet paid.
Every time a patient is seen and a claim is submitted, that amount sits in your AR until the insurance company pays, the patient pays, or the claim gets written off. In a perfect world, claims get paid within 30 days and your AR stays clean. If claims get denied, underpaid, ignored, or lost in the system and your AR starts to age.
The longer a claim sits unpaid, the harder it becomes to collect. That’s not an opinion. It’s a fact backed by industry data. Claims under 30 days old have a collection rate close to 90%. Claims over 120 days old? That number drops below 50% for many payer types. After 180 days, you’re often looking at writing it off entirely. That’s the revenue your practice has already earned. Revenue that’s just sitting there, uncollected.
What is AR Recovery in Medical Billing?
AR Recovery is the systematic process of identifying, working, and collecting on claims that haven’t been paid whether they were denied, rejected, underpaid, or simply never followed up on.
It’s different from your day-to-day billing cycle. Regular billing handles new claims going out. AR recovery in medical billing handles everything that came back wrong, got stuck, or got forgotten.
A good AR recovery process includes reviewing every unpaid claim, identifying why it hasn’t been paid, taking the right corrective action whether that’s resubmitting, appealing, correcting coding errors, or following up directly with the payer and tracking it through to resolution. It’s not glamorous work. But it directly determines how much money your practice actually keeps.
Why AR Piles Up in the First Place
Before you can fix an AR problem, it helps to understand how it got there. The honest answer is that AR builds up for a lot of different reasons, and most practices are dealing with several at once.
Denials that nobody followed up on. If the claim is denied, the post-denial code gets recorded, and it “stays denied. It may have fallen through the cracks in a hectic period, or the team may not have had time to work on it, or not know how. Take a single claim and multiply it by hundreds of claims a month and you will see how quickly it can accumulate.
Errors in the code that were not detected during submission. Incorrect diagnosis codes, mismatched procedure codes, and no modifiers. These cause rejections or denials that must be corrected before resubmission.
If there’s no clear process for catching and fixing these, they just age in the queue.
Authorization issues discovered after the fact. A claim gets denied because prior authorization wasn’t obtained or wasn’t documented correctly. These can sometimes be appealed retroactively, but the window closes fast.
Payer delays and non-responses. Some payers are simply slow. Claims get stuck in processing, requests for additional information go unanswered, or a payer system issue creates a backlog. Without active follow-up, these claims just sit.
High staff turnover or understaffed billing teams. This one’s uncomfortable to talk about, but it’s real. When your billing department is stretched thin or going through turnover, AR follow-up is usually the first thing that gets deprioritized. New claims have to go out. Old claims get pushed to tomorrow. Tomorrow turns into next month.
Patient balance issues. AR isn’t just about insurance. Patient responsibility balances that go uncollected especially after insurance has paid contribute to your overall AR aging too.
What Does a Healthy AR Recovery in Medical Billing Look Like?
Here’s a benchmark most practice management consultants use:
- Claims under 30 days should represent at least 50% of your total AR
- Claims between 31 and 60 days should be around 20 to 25%
- Claims between 61 and 90 days should be under 15%
- Claims over 90 days should be under 10% of the total AR
- Claims over 120 days are the danger zone. Anything significant here needs immediate attention
Your AR days (also called Days in AR or DAR) are another key metric. This is the average number of days it takes to collect payment after a service is rendered. For most specialties, a healthy benchmark is under 40 days. If you’re sitting above 50 or 60 days, that’s a sign your AR recovery process needs work.
How AR Recovery in Medical Billing Actually Works Step by Step
Good AR recovery is not just calling payers and hoping for the best. It’s a structured process that requires prioritization, documentation, and follow-through.
Pull and Segment your AR Aging Report
First, prepare an aging schedule of the total AR on a payer basis, then on the age bucket basis of 0 to 30 days, 31 to 60 days, 61 to 90 days, 91 to 120 days, and more than 120 days. Do not attempt to do it all at once. You will be diluting your efforts with no results. Prioritizing by dollar value and by age, the highest dollar claims in the 61-to-120-day range are usually your best starting point because they’re still collectible and the return on effort is highest.
Identify the Root Cause for Each Claim
Determine the reason behind the unpaid status of the claim. Find out whether it is a denial, rejection or pending status, or whether there is a patient responsibility balance that has never been billed. Identifying the reason behind the unpaid status of the claim will tell what kind of action needs to be taken next. Submission, appeal, coding adjustment, appeal of authorization, or patient letter each of these situations requires different actions.
Take the Right Corrective Action
Here is where the actual recovery process takes place.
For denied claims, examine the reason behind the denial, make necessary corrections to it, and submit again or appeal the denial if it is incorrect. Every insurance carrier has its own process of appeal, and good appeal documentation with clinical notes helps in winning cases more often than people think.
For rejected claims, the solution is often quite fast.
Rejection most often means that the claim did not get processed because of some technical issue like an incorrect member number, a wrong code, missing data, etc.
For pending claims that have been sitting too long, call the payer directly. Get a reference number for every call. Document the date, the representative’s name, what they said, and what the next step is. If a payer says they need additional information, send it the same day.
For patient balances, make sure statements are going out consistently and that your team is following up after a set number of days with a call or second statement.
Document Everything
This sounds tedious, but it matters. Every action taken on every claim should be documented in your practice management system date, action, outcome, and next follow-up date. This keeps claims from slipping through again and gives you a paper trail if you need to escalate.
Identify and Fix Systemic Issues
Here’s the part most practices skip. If the same denial reason keeps showing up across hundreds of claims, the problem isn’t those individual claims. It’s a process issue upstream. Maybe a specific payer requires modifier 25 on every E&M with a procedure and your team doesn’t know that. Maybe prior auth requirements changed and nobody updated the workflow. Real AR Recovery in medical billing doesn’t just collect on old claims. It identifies patterns that prevent new claims from aging in the first place.
When to Bring in Outside Help for AR Recovery
There’s a point at which internal AR recovery efforts hit a ceiling. Your team can only work so many claims per day, and if the backlog is large enough, you’re often just keeping up with new aging rather than making a dent in the old. Signs it’s time to bring in outside support:
- Your AR over 90 days represents more than 15% of the total AR
- Days in AR have been climbing for three or more consecutive months
- Your team is spending more than half its time on denials rather than new submissions
- You’ve had significant staff turnover in billing and AR has grown in the gap
- You’ve identified a large batch of aged claims but don’t have the bandwidth to work them
Outsourcing AR Recovery either for a defined cleanup project or on an ongoing basis can bring in revenue that would otherwise be written off. A good AR recovery team works on contingency or flat fee, meaning you’re not paying for work that doesn’t produce results.
Frequently Asked Questions
How is AR recovery different from regular medical billing?
Regular billing handles the front end submitting new claims, verifying eligibility, and collecting copays. AR recovery handles the back end going after claims that didn’t pay the first time. Both are part of a complete revenue cycle, but they require different skills, different workflows, and different tools. Many practices are strong on the front end and weak on the back end, which is why AR builds up over time.
What is a good AR day benchmark for medical practices?
Under 40 days is considered healthy for most specialties. Primary care and high-volume practices sometimes achieve 30 days or less with strong billing processes. Surgical specialties with more complex claims and prior auth requirements sometimes run closer to 45 to 50 days. Anything consistently above 55 to 60 days is a signal that AR recovery needs attention.
Can old claims really still be collected after 120 days?
Yes but it depends on the payer and the reason the claim is unpaid. Some payers have timely filing limits that cut off at 12 months from the date of service, while others go to 24 months. If the claim is still within the filing window and the denial or delay wasn’t due to a contractual issue, collection is often possible. The key is knowing the specific payer’s rules and acting before the window closes.
Is it worth outsourcing AR recovery?
For most practices dealing with significantly aged AR, yes. An experienced AR recovery team works claims faster than an in-house team that’s also managing day-to-day billing, and they typically know payer-specific denial patterns that speed up resolution. The return on investment is usually positive you are collecting revenue that would otherwise have been written off.
Conclusion
At the end of the day, every dollar sitting in your aged AR is a dollar your practice already worked for. The patient was seen. The service was rendered. The claim was submitted. You earned it. The difference between practices that thrive financially and practices that constantly feel cash-strapped often isn’t volume. It’s how effectively they collect what they’re already owed.
