Reducing AR Over 90 Days: Strategies That Work

A/R Over 90 Days Is Not the Problem. It Is the Symptom.

Many organizations treat aging accounts receivable as a collections problem.

As balances continue to age beyond 90 days, leadership often responds by increasing follow-up efforts, assigning additional staff, or implementing aggressive collection strategies.

While these actions may generate short-term improvements, they rarely address the underlying causes.

The reality is that A/R over 90 days is often the result of issues that occurred weeks or even months earlier.

High-performing revenue cycle organizations understand that reducing aged A/R requires a disciplined approach focused on prevention, accountability, and process improvement—not simply working accounts harder.

Why A/R Over 90 Days Matters

A/R over 90 days represents revenue that has become increasingly difficult to collect.

As accounts age:

• Collection probability decreases
• Staff effort increases
• Cash flow slows
• Write-off risk grows
• Financial forecasting becomes less predictable

Large balances in aging buckets often indicate broader revenue cycle challenges that require executive attention.

Start With Root Cause Analysis

Before launching a collections initiative, organizations should determine why balances are aging.

Common causes include:

• Authorization denials
• Eligibility issues
• Missing documentation
• Medical necessity denials
• Untimely follow-up
• Underpayments
• Unworked claim rejections
• Ineffective patient collections

Without understanding the root cause, teams risk treating symptoms rather than solving problems.

Key Question

Why did these accounts reach 90 days in the first place?

---

Segment A/R by Category

Not all aged accounts are the same.

Successful organizations segment aging balances into actionable categories.

Examples include:

Denied Claims

Accounts delayed due to unresolved denials.

No Response Claims

Claims requiring additional payor follow-up.

Underpayments

Claims paid incorrectly or below contracted rates.

Patient Responsibility

Balances requiring patient outreach and collection efforts.

Documentation Requests

Claims awaiting medical records or additional clinical information.

Segmentation helps teams prioritize work based on recoverability and financial impact.

---

Focus on High-Dollar Opportunities First

Many organizations work aging accounts in date order.

This often results in staff spending significant time on low-value balances while larger opportunities remain unresolved.

Instead, prioritize:

• High-dollar claims
• High-value denials
• Major payor balances
• Accounts nearing timely filing deadlines
• Significant underpayment opportunities

Recovering a handful of high-dollar accounts can often produce greater results than resolving hundreds of smaller balances.

---

Monitor Denials Aggressively

Denials are one of the leading drivers of aged A/R.

Organizations with large balances over 90 days often discover that denial management processes are inconsistent or reactive.

Focus on:

• Top denial categories
• Top denial payors
• Denial aging
• Appeal success rates
• Authorization denial trends

The longer a denial remains unresolved, the lower the likelihood of successful recovery.

---

Improve Front-End Processes

Many aging issues originate long before a claim is submitted.

Front-end improvements often produce the greatest long-term impact on A/R performance.

Key focus areas include:

Eligibility Verification

Confirm coverage before services are rendered.

Authorization Management

Ensure approvals are obtained and tracked appropriately.

Accurate Registration

Reduce demographic and insurance errors.

Financial Clearance

Improve patient responsibility collection processes.

Organizations that strengthen front-end workflows typically see reductions in denials, rework, and aging balances.

---

Establish Accountability Through Work Queues

One of the most common causes of aging A/R is inconsistent follow-up.

Accounts sit untouched because ownership is unclear or workflows are not standardized.

Best practices include:

• Assigned work queues
• Defined follow-up frequencies
• Escalation protocols
• Productivity expectations
• Performance monitoring

Aged accounts should never remain stagnant due to workflow gaps.

---

Analyze Payor Performance

Some payors consistently contribute more heavily to aging balances.

Organizations should evaluate:

• Days to pay by payor
• Denial rates by payor
• Appeal success rates
• Underpayment trends
• Outstanding balances by payor

Understanding payor behavior helps organizations identify where operational efforts should be concentrated.

---

Evaluate Collectability

Not all aged balances are recoverable.

Organizations should routinely assess:

• Likelihood of recovery
• Appeal opportunities
• Timely filing status
• Patient collectability
• Contractual limitations

This creates a more realistic view of collectible A/R and improves financial forecasting accuracy.

---

Build an Aging Dashboard

Executive visibility is essential.

A strong A/R aging dashboard should include:

• Total A/R
• A/R over 90 days
• Aging by payor
• Aging by financial class
• Top denial categories
• High-dollar outstanding balances
• Collection trends

Leadership should be able to quickly identify emerging risks before balances become unmanageable.

---

What High-Performing Organizations Do Differently

Organizations that consistently maintain low A/R over 90 days typically:

✔ Monitor denial trends proactively

✔ Prioritize high-dollar opportunities

✔ Maintain disciplined follow-up processes

✔ Strengthen front-end workflows

✔ Track payor performance

✔ Use analytics to identify aging risks early

✔ Hold teams accountable through structured work queues

Their success comes from preventing aging—not simply chasing it.

Executive Takeaway

A/R over 90 days is one of the clearest indicators of revenue cycle performance.

When balances continue to age, the issue is rarely a lack of follow-up alone.

The true drivers are often denials, operational inefficiencies, payor delays, workflow breakdowns, and front-end process failures.

Organizations that focus on identifying and correcting these root causes achieve sustainable improvements in both cash flow and financial performance.

Reducing aged A/R is not about working harder. It is about working smarter.

Questions Every CFO Should Be Asking

• What is driving our A/R over 90 days?
• Which payors contribute the most aging?
• What percentage of aged A/R is truly collectible?
• Which denial categories are creating the greatest delays?
• Are our teams preventing aging or simply managing it?

The answers to these questions often reveal the most significant opportunities for revenue cycle improvement.
