Why Most AR Programs Underperform
Most practices manage AR reactively, working claims only when someone asks, a statement cycle runs, or aging becomes alarming. This produces high days in AR, timely-filing write-offs, and collections well below what is owed. Effective AR management needs a proactive, daily, prioritized follow-up program, not an occasional aging report review.
Best Practice 1: Work AR Daily with a Prioritized Queue
Every AR specialist should start each day with a work queue ranking open accounts by dollar value, days outstanding, payer type, and days left until the timely filing deadline. High-dollar claims nearing deadlines come first, not the easiest or most familiar accounts. A disciplined daily queue is the most direct lever for reducing days in AR.
Best Practice 2: Know Your Payers — Each One Is Different
Medicare, Medicaid, and each commercial carrier have different timely filing windows, inquiry processes, portal capabilities, escalation paths, and adjudication timelines. Build payer-specific workflows covering the best follow-up channels, times to call, and escalation contacts for stalled claims.
Best Practice 3: Protect Timely Filing with Early Alerts
Timely filing deadlines range from 90 days to two years depending on the payer, with Medicare at one year a common benchmark. Missed deadlines mean denial with virtually no recovery, among the most preventable revenue losses. Implement automated alerts that flag claims approaching their deadline at 30, 60, and 90 days before expiration, not after it has passed.
Best Practice 4: Use Real-Time Claim Status Inquiries
Rather than waiting for a remittance or calling general member services, use 276/277 electronic claim status transactions to query status in real time. Most payers return adjudication status, denial reason codes, and expected payment dates, which reduces follow-up time and focuses calls on claims that need human intervention.
Best Practice 5: Tackle Your Aged AR Backlog
If your practice has significant AR in the 90+ or 120+ day buckets, those claims need immediate attention, not just better processes going forward. A dedicated cleanup, working the highest-value accounts first with payer-specific appeals and corrected claims, can recover revenue staff had assumed was lost. Results vary by payer, claim age and appeal eligibility, and some write-offs are not recoverable.
Key Takeaways
Work AR from a prioritized daily queue, track a small set of metrics monthly, follow a consistent step sequence on every unpaid claim, and escalate on a schedule instead of waiting for balances to age. The sections below add the formulas and workflows to put this into practice.
The AR Metrics Worth Tracking
An AR program cannot improve what it does not measure. Track four or five numbers consistently. Your billing system may calculate these slightly differently, so confirm the formula behind any report.
| Metric | Formula | What it tells you |
|---|---|---|
| Days in AR | Total outstanding AR / average daily charges | Average time to turn charges into cash |
| % of AR over 90 days | AR older than 90 days / total AR | How much receivable risks becoming uncollectible |
| Net collection rate | Payments / (charges - contractual adjustments) | How much collectible revenue you actually collect |
| Denial rate | Denied claims / claims submitted | Whether problems originate before or after submission |
| First-pass resolution rate | Claims paid correctly on first submission / claims submitted | How much rework your team is absorbing |
Illustrative example (made-up numbers). A practice posts $900,000 in charges over 90 days, so average daily charges are $10,000. With total AR of $350,000, days in AR is 35. If $105,000 of that AR is older than 90 days, 30% is over 90 days, a signal to investigate even though headline days in AR looks acceptable.
Read days in AR alongside the aging buckets; one average can hide a growing stack of old claims.
Reading the Aging Report
The aging report groups open balances by age, commonly 0-30, 31-60, 61-90, 91-120, and over 120 days. Review insurance and patient AR separately, and break insurance AR down by payer. One slow payer, clinic location, or denial reason often explains most of the aged balance, and fixing the cause is worth more than working each claim individually.
Also check for balances that never entered a follow-up cycle, such as claims with no submission date, claims stuck as rejected at the clearinghouse, and partially paid claims whose remaining balance was never reviewed. They do not look overdue, so they are easy to miss.
A Step-by-Step Workflow for Every Unpaid Claim
Give every specialist the same sequence.
- Confirm the claim was receivedCheck clearinghouse acknowledgments (commonly 999 and 277CA) to verify the payer accepted the claim. A rejected claim never entered adjudication, so waiting will not produce payment.
- Check status electronicallySend a 276 request and read the 277 response. Note the status category, denial information, and payer claim number.
- Check whether a remittance already postedLook for an ERA (835) or EOB received but not posted, or posted incorrectly. Many "unpaid" claims have been paid.
- Call only when electronic status is unclearHave the claim number, date of service, billed amount, and NPI ready. Record the representative's name, date, reference number, and promised next step.
- Identify the root causeClassify the problem as registration, eligibility, coding, authorization, documentation, payer error, or timely filing. The category decides whether the fix is a corrected claim, appeal, or reprocessing request.
- Take the corrective actionSubmit the corrected claim, appeal with records, or request reprocessing. Attach what the payer asked for and keep proof.
- Set a dated follow-upEvery touched account leaves with a next-action date; without one it becomes the next aged balance.
- Feed the cause back upstreamReport recurring causes to front-desk, coding, or provider leads.
Follow-up Cadence and Escalation
Adjust timing to each payer's processing time; a common cadence follows.
| Claim age | Typical action | Owner |
|---|---|---|
| Days 1-7 | Confirm clearinghouse acceptance and fix rejections | Billing |
| Days 14-21 | First electronic status check on unpaid claims | AR specialist |
| Days 30-45 | Phone if status is unclear or stalled; start corrected claim or appeal if denied | AR specialist |
| Days 60-90 | Escalate to payer representative or senior specialist; review filing and appeal deadlines | AR lead |
| Over 90 days | Review every balance and document a decision to recover, adjust, or transfer to patient | AR lead and manager |
When a claim stalls, escalate in order: ask for a supervisor on the call, then the payer's provider relations or representative, then any formal dispute or complaint process. State agencies commonly oversee prompt-payment rules for fully insured commercial plans, but details vary by state and plan type, so confirm what applies before citing them.
Prioritizing the Daily Queue
Rank accounts first by days remaining to the timely filing or appeal deadline, then by expected recovery (balance multiplied by likelihood of a fix), then by payer. Clear quick wins, such as unposted payments and status checks, in a short first block.
Illustrative example (made-up numbers). Claim A is $3,000 with 20 days left to the appeal deadline. Claim B is $5,000 with 150 days left. Work Claim A first; the deadline is the real constraint.
Common AR Mistakes and How to Fix Them
| Mistake | Why it hurts | Fix |
|---|---|---|
| Working the easiest accounts first | High-value, deadline-sensitive claims age out | Rank by deadline and expected recovery |
| Calling before checking electronic status | Wastes time on answers available online | Use 276/277 first and call only for exceptions |
| No notes or reference numbers | Calls repeat and promises cannot be enforced | Use a standard note template for every contact |
| Treating denials as one-off events | The same cause keeps generating denials | Track denials by reason code and review monthly |
| Writing off balances without review | Recoverable revenue is lost permanently | Require a documented reason and approver for write-offs |
| Letting patient balances age before billing | Collectability falls as balances get older | Bill patients promptly after adjudication |
A Monthly AR Review Checklist
- Review the five metricsCompare days in AR, percent over 90 days, net collection rate, denial rate, and first-pass rate to last month and quarter.
- Review by payer and locationIdentify any payer or site drifting from the rest.
- Audit a sample of write-offsConfirm each was valid and approved.
- Review the top denial reasonsAssign each to an owner with a fix date.
- Check upcoming deadlinesList all claims within 60 days of timely filing or appeal limits.
