Most behavioral health practices aren’t losing money because their actual care or billing codes are messed up. The real problem is nobody’s followed up on the claims that didn’t get paid the first time around.
The aged AR goes beyond just the payer issues. It’s a bigger operational issue that impacts how revenue cycles run. Unlike a claim that’s just denied and can still be appealed, once aged AR goes past the payer’s deadline, it’s permanently uncollectible, regardless of claim submission accuracy.
Practices in behavioral health typically have a chunk of their monthly billed charges left unpaid for over 90 days – we’re talking 8% to 15%. If a practice bills $600,000 a year, that’s $48,000 to $90,000 sitting out there unpaid. That money is either trickling in, getting written off too soon, or just stuck in limbo.
Let us explore what aged AR is, how it impacts behavioral health billing, and a 5-step framework that turns those outstanding bills back into collected revenue.
What is Aged AR and Why Does It Matter for Behavioral Health Practices?
Aged accounts receivable means claims that haven’t been paid after a certain amount of time from when the care was delivered. They’re sorted into groups: 0-30 days, 31-60, 61-90, and 90+ days. Any claim sitting past 90 days needs immediate attention.
AR in behavioral health gets old faster and is harder to fix than in a lot of other medical fields. Here’s why:
- Payers usually have really short deadlines for behavioral health claims, like 90 to 180 days from the date of care delivery. Once that window closes, getting reimbursed is close to impossible.
- Compared to general medicine, behavioral health claims get denied more often, meaning way more work to fix.
- Things like incorrect routing for mental health benefits organizations (MBHOs), missing authorizations, or notes that aren’t complete add up. This pile of denied claims goes up fast if practices don’t have people focused just on AR.
Is Your Aged AR Growing Faster Than Your Practice?
Behavioral health billing errors can quietly tank your bottom line. Let our team of credentialing and billing experts clean up your aging claims and fix the root causes of your denials.
Why Do Behavioral Health Claims End Up in Aged AR?
Several issues frequently recur across behavioral health revenue cycle operations:
- Eligibility verification failures resulting in denials that remain unresolved
- Authorization lapses for IOP, PHP, and residential treatment services
- MBHO routing errors where claims are sent to the incorrect payer entity and remain pending adjudication
- Coding discrepancies involving time-based CPT code selection
- Missing modifiers required for telehealth and specialty billing scenarios
- Documentation deficiencies that fail to support medical necessity requirements
- Provider credentialing delays resulting in retroactive denials
- Extended payer processing timelines and adjudication delays
5 Steps To Recover Aged AR In Behavioral Health Billing
Step 1: Prioritize AR Strategically
- Don’t just clear your daily work queue; analyze your AR aging report.
- Focus first on claims aged 61–90 days. These still have the possibility of getting paid since they usually fall within payer deadlines.
- Prioritizing claims over 90 days risks spending your time on cases that might already be dead ends.
- It’s easier to resolve low-dollar claims, but choose the ones that move the revenue needle and are still eligible.
Step 2: Organize Claims Before Attacking
- Before you work on reimbursement activities, categorize your claims.
- Group the claims by denial code and root cause.
- If several denials have the same root cause, it can be fixed in a single cycle. This approach reduces staff workload and boosts recovery.
- Give top priority to claims near filing deadlines, bigger-dollar claims with fixable errors, denials you can build a strong appeal for, and underpayments your contract analysis has flagged.
Step 3: Set Up a Real Process for Denial Recovery
Each denial category requires a remediation strategy; don’t just resubmit the claim.
If you’ve sent a claim to the wrong payer or MBHO, get it to the right destination.
- Missing info or modifiers? File a corrected claim.
- Got a medical necessity denial? Pull clinical notes and appeal.
- Run into authorization denials? Chase retroactive authorization or peer review.
- Timely filing denials? Gather and submit your proof.
- Bundling issues? Apply the correct modifiers and go again.
Don’t just send duplicates; fix the actual issue, or you’ll keep piling up denials and lose more time.
Step 4: Implement a Consistent Follow-Up Cadence
Follow-up without a structured process often becomes an inconsistent collection process.
Recommended timeline:
- Day 30: Verify claim status through clearinghouse and payer portals
- Day 45: Contact payer representatives if payment remains outstanding
- Day 60: Submit appeals or corrected claims
- Day 75: Escalate high-value claims and review appeal status
- Day 90: Determine final escalation strategy or documented write-off
Avoid labeling claims as “pending” without a documented next-action date. Claims without ownership and follow-up plans risk exceeding payer filing deadlines.
Every payer interaction should include:
- Date of contact
- Representative name
- Reference number
- Next action commitment
- Follow-up deadline
Step 5: Escalate or Close Claims Based on Defined Criteria
- You don’t have to chase every claim forever. Escalate if you believe a payer’s not honoring parity laws, if there’s a large medical necessity denial that needs peer-to-peer review, or if the payer just isn’t responding.
- Write off claims only after you’re sure filing limits are dead, costs outweigh the return, or all appeals are done.
- Don’t let go of any claim without a paper trail; every write-off should show its full history and a clear reason why.
- Remember, disciplined AR management isn’t just about cleaning up old claims; it’s about understanding where things get stuck and using every tool you have to keep revenue flowing.
Your AR Has a Deadline.
Claims sitting in your 90-plus day bucket are closer to write-off than you think. The Behavioral Health Operations Playbook includes the AR recovery framework, denial triage process, and KPI benchmarks your team needs to stop the bleeding.
Which Behavioral Health KPIs Should You Track During AR Recovery?
Successful AR management requires continuous monitoring of key performance indicators:
- AR Over 90 Days: Less than 10%
- Net Collection Rate: Greater than 95%
- First Pass Resolution Rate: Greater than 90%
- Denial Rate: Less than 5%
- Days in AR: Less than 35 days
- Underpayment Rate: Monitored against contracted reimbursement schedules
These metrics provide visibility into collection efficiency, denial trends, and revenue leakage risks.
What Mistakes Prevent Behavioral Health Practices From Recovering Revenue?
The most common revenue recovery failures include:
- Prioritizing low-value claims over high-value opportunities
- Resubmitting denied claims without root-cause correction
- Missing filing deadlines while awaiting documentation
- Failing to categorize denials systematically
- Lacking formal escalation procedures
- Writing off claims based on age rather than financial analysis
- Missing payer-specific filing deadlines
- Accepting underpayments without contract validation
Turn Your 90+ Day Aging Bucket Into Cash Flow
Don’t let timely filing limits expire on your hard work. Learn how to audit, prioritize, and successfully appeal stale behavioral health claims before that revenue disappears forever.
When Should Behavioral Health Organizations Consider Outsourced AR Recovery?
Organizations should evaluate outsourced AR services when:
- AR over 90 days continues to increase despite active collection efforts
- Key billing personnel have departed without transition planning
- Multi-site operations lack centralized AR visibility
- Denial rates exceed established benchmarks
- Internal staff lack specialized payer and reimbursement expertise
- Recovery costs outweigh internal collection efficiency

Frequently Asked Questions
What does aged AR mean in behavioral health?
Aged AR means insurance claims that’re still unpaid after 90 days from the service date. Claims that are 61 to 90 days old are also at risk. Need to be checked before deadlines.
When should we follow up on behavioral health claims?
You should start following up within 30 days of submitting a claim if you haven’t received payment. If a claim is still not resolved after 60 days, you need to pay attention to avoid delays in getting paid.
What is a good AR aging percentage for health practices?
Ideally, AR that is over 90 days old should be less than 10% of total AR. If it’s more than 15%, it might mean there are problems with managing denials or following up on claims.
Can we still get paid for denied behavioral health claims after 90 days?
Yes, you can, if the payer deadline for filing claims hasn’t passed and you can fix the denial with documentation, coding updates, or an appeal.
When should a behavioral health practice think about getting help with AR recovery?
If aged AR keeps increasing, denials are still high, or your team doesn’t have the skills or time to handle complex follow-ups and appeals, consider getting help.
Why do behavioral health claims take a long time for reimbursement over 90 days?
The main reason is that you don’t follow up consistently. Claims often stay unresolved because behavioral health providers miss follow-ups, delay appeals, or don’t have a process for managing AR.
