A standard AR summary shows the total outstanding receivables organized by aging buckets (Current, 1–30 days, 31–60 days, 61–90 days, Over 90 days) revealing how much revenue remains uncollected and how long claims have been unpaid—with healthcare practices collecting $1M–$5M+ monthly losing $1.2M–$3.8M annually when AR aging reports show 18–28% of receivables in the Over 90 days “Old AR” category, indicating systematic denial patterns, payer variance detection failures, and denial root-cause engineering gaps that suppress EBITDA and net realized revenue growth through working capital depletion requiring credit line borrowing.
For multi-provider healthcare practices, understanding what a standard AR summary reveals about revenue cycle health is the foundation of implementing risk mitigation protocols through targeted 90-Day Audit and AR Recovery strategies.
What Information Does a Standard AR Summary Contain?
Table 1: Standard AR Summary Structure
| AR Aging Bucket | Definition | Healthy Benchmark | Warning Threshold | Revenue Cycle Health Indicator |
| Current | Within payment terms (0–30 days) | 60–70% | <50% | Strong payer mix, clean claims |
| 1–30 Days | Recently overdue | 15–20% | >25% | Normal follow-up required |
| 31–60 Days | Requires active pursuit | 8–12% | >15% | Denial patterns emerging |
| 61–90 Days | High-priority collection | 3–5% | >8% | Systematic issues present |
| Over 90 Days (Old AR) | Critical collection risk | <5% | >12% | Severe revenue cycle dysfunction |
Financial Performance Metrics Insight:
For practice, collecting $3M monthly with 22% in the Over 90 days bucket:
- Old AR balance: $660,000
- Collection probability: 35–45% (vs. 95%+ for Current bucket)
- Expected write-off: $363,000–$429,000
The 90-Day Audit: Why This Bucket Matters Most
According to the U.S. Small Business Administration, maintaining healthy cash flow requires consistent AR monitoring to prevent working capital depletion.
90-Day Revenue Audit Focus:
Healthcare practices should conduct monthly 90-Day Audits, analyzing:
- Which payers contribute most to Old AR (Medicare, UnitedHealthcare, Aetna, BCBS)
- Which providers generate the highest Old AR percentages
- Which CPT codes face systematic aging patterns
- Which denial codes dominate 90+ day claims
Denial Root-Cause Engineering Through 90-Day Audit:
Case Study: Practice with $480,000 in Old AR
90-Day Audit reveals:
- 67% from UnitedHealthcare claims
- 82% are authorization denials
- All involve CPT 99214-99215 E/M codes
- The pattern started 6 months ago
Root Cause: UnitedHealthcare implemented new prior authorization requirements for high-level E/M codes not reflected in practice workflows
AR Recovery Action:
- Immediate staff training on new auth requirements
- Retroactive authorization requests for denied claims
- Forward-looking authorization automation
- Result: $288,000 recovered from Old AR, future denials prevented
AR Recovery Strategies Based on Standard AR Summary Data
Technological Efficiency Protocol:
| AR Aging Bucket | Efficiency Protocol / Action |
| 0–30 Days | Automated patient statements, online payment portals |
| 1–30 Days | Automated payer follow-up, electronic claim status checks |
| 31–60 Days | Human intervention, denial analysis, appeal preparation |
| 61–90 Days | Manager-level escalation, executive payer relations contact |
| Over 90 Days (Old AR) | Specialized AR recovery protocols, write-off evaluation |
Payer Variance Detection Through AR Aging:
- Medicare Pattern: Consistently pays within 14–21 days → Current bucket
- Commercial Payer A: 45% of claims in 31–60 day bucket → Systematic delays requiring contract review
- Commercial Payer B: 38% of claims in 90+ day bucket → Severe denial patterns requiring immediate intervention
Risk Mitigation Strategy:
When the standard AR summary shows payer-specific aging concentration, practices should:
- Analyze denial codes for that payer
- Review contract language for payment timeline requirements
- Escalate systematic delays to payer relations
- Consider payer contract renegotiation or termination
The Old AR Crisis: When to Write Off vs. Pursue
Medical Billing Services Decision Matrix:
Pursue AR Recovery When:
- Claim in 90+ days, but the appeal window is still open
- Payer error (not patient responsibility)
- High dollar value ($500+)
- The pattern suggests a systemic fix will prevent future occurrences
Consider Write-Off When:
- Timely filing deadline passed
- Patient responsibility with collection probability <20%
- Pursuit cost exceeds recovery probability
- Small balance (<$50) with high collection effort
EBITDA Impact:
Practices writing off 18–28% of revenue in the Old AR experience:
- 12–18% EBITDA suppression
- Working capital depletion requires credit lines
- Bad debt tax implications
- Net Realized Revenue Growth: Negative despite strong procedure volume
Medical Billers and Coders’ 25+ years of experience deliver systematic Old AR Recovery, reducing write-offs from 18–28% to 3–5% through denial root-cause engineering and payer variance detection.
Transform Your Standard AR Summary From Warning Sign to Action Plan
If your healthcare practice, collecting $1M–$5M+ monthly, shows 18–28% of receivables in the Over 90 days Old AR bucket on your standard AR summary, systematic revenue cycle failures pose a $1.2M–$3.8M annual write-off risk.

Frequently Asked Questions
A standard AR summary shows total outstanding receivables organized by aging buckets (Current, 1–30, 31–60, 61–90, Over 90 days), revealing collection health—when 18–28% sits in Over 90 days “Old AR,” it indicates systematic denial patterns, payer delays, and revenue cycle dysfunction creating $1.2M–$3.8M annual write-off risk for $1M–$5M monthly collection practices.
The “Old AR” bucket over 90 days is critical because collection probability drops from 95%+ (Current) to 35–45% (90+ days). Healthy practices maintain <5% in this bucket, while practices with >12% experience severe revenue cycle dysfunction requiring immediate 90-Day Audit to identify denial root causes and implement AR Recovery protocols.
Healthcare practices should conduct monthly 90-Day Revenue Audits to analyze which payers, providers, CPT codes, and denial codes dominate Old AR—enabling denial root-cause engineering to identify systematic issues (such as new prior authorization requirements) that cause aging patterns and implement targeted AR Recovery, recovering $288,000+ from previously written-off claims.
A standard AR summary provides high-level total balances by aging bucket and payer, while AR detail reports list every individual claim with specific denial codes, dates, and transaction details—healthcare practices need both: summary for strategic 90-Day Audit focus and detail for denial root-cause engineering and claim-level AR Recovery actions.
Specialized Medical Billing Services use standard AR summary data to identify payer-specific aging concentrations, conduct 90-Day Audits revealing denial patterns, implement denial root-cause engineering preventing future Old AR accumulation, execute targeted AR Recovery on 90+ day claims, and apply payer variance detection, reducing write-offs from 18–28% to 3–5%—protecting EBITDA and net realized revenue growth.
