AR days, or Days in Accounts Receivable, measure how long it takes for a healthcare provider to collect payments after services are rendered.
High AR days can lead to:
- Cash flow delays
- Increased write-offs
- More aged claims
- Higher denial risk
- Operational inefficiencies
- Patient dissatisfaction
Low AR days indicate:
- Efficient revenue cycle management
- Faster reimbursement
- Strong financial stability
- Fewer denials and errors
How Much Accounts Receivables Should Be Maintained in Healthcare?
Ideal AR Days Benchmark: 30–40 Days
Most healthcare financial experts recommend maintaining 30–40 AR days for a financially healthy organization.
This is considered the industry standard for:
- Hospitals
- Physician practices
- Specialty clinics
- Surgery centers
Best-in-Class Performance: Under 30 Days
High-performing healthcare organizations with optimized RCM workflows maintain AR days under 30 days.
Warning Zone: Above 50 AR Days
If AR days exceed 50 days, it signals serious revenue cycle issues.
This often indicates:
- Denial management problems
- Slow charge posting
- Poor coding accuracy
- Payer delays
- Lack of follow-up
- Authorization issues
- Missing or incomplete documentation
Critical Zone: Above 60–70 Days
AR above 60–70 days can severely damage cash flow, leading to operational challenges and increased financial risk.
Ideal AR Distribution by Aging Buckets
To understand how much accounts receivables should be maintained in healthcare, we should also review AR aging benchmarks.
Recommended AR Aging Breakdown:
| AR Bucket | Ideal % of Total AR |
| 0–30 Days | 55%–70% |
| 31–60 Days | 15%–25% |
| 61–90 Days | 5%–10% |
| 91–120 Days | under 5% |
| 120+ Days | under 3% (best-in-class: under 1%) |
If more than 15–20% of AR is in the 90+ bucket, the organization needs immediate revenue cycle improvements.
Factors That Impact AR Days in Healthcare
1. Claim Denials
Denials are a major contributor to increased AR days.
Common causes include:
- Incorrect coding
- Missing documentation
- Authorization errors
- Eligibility issues
- Invalid modifiers
2. Slow Charge Posting
Delays in charge entry directly increase AR days.
3. Poor Patient Collections
As patient responsibility grows, many organizations see AR increasing.
4. Insurance Delays
Payers may delay claims due to:
- Medical necessity reviews
- Coordination of benefits
- Policy changes
5. Understaffed or Untrained Billing Team
Lack of skilled AR follow-up specialists leads to aged claims.
How to Maintain Optimal Accounts Receivables in Healthcare
Below are proven ways to keep AR days at recommended levels.
1. Strengthen Eligibility & Benefits Verification
Most denials start here.
Verify:
- Coverage
- Benefits
- Deductibles
- Co-insurance
- Prior authorizations
2. Implement Clean Claim Submission Processes
Aim for a clean claim rate of 95%+.
Includes:
- Correct coding

- Scrubbing claims before submission
3. Improve Denial Management Workflow
A strong denial management strategy can reduce AR by 20–30%.
Focus on:
- Root cause analysis
- Tracking denial trends
- Fast resubmission
- Preventive training
4. Accelerate Charge Posting
Post charges within 24–48 hours.
Faster posting = faster billing = faster payments.
5. Enhance AR Follow-Up
Active AR follow-up can reduce aged claims by 40%.
Includes:
- Regular payer calls
- Reopen denied claims
- Address delayed accounts
- Track every open claim
6. Automate Key Revenue Cycle Functions
Automation tools improve accuracy and reduce AR days.
Automate:
- Eligibility checks
- Claim scrubbing
- Payment posting
- Denial tracking
7. Improve Patient Collections
Offer:
- Payment plans
- Online payment options
- Transparent billing
8. Outsource Medical Billing
Healthcare providers often reduce AR by 20–40% when outsourcing to specialized RCM companies.
How Much AR Should Healthcare Providers Maintain? Final Recommendation
To summarize, the ideal Accounts Receivable for healthcare is:
Target AR Days: 30–40 Days
Best-in-Class: Under 30 Days
Warning Zone: Above 50 Days

Ideal AR Aging Structure
- 55%–70% in 0–30 days
- 15%–25% in 31–60 days
- Under 10% in 61–90 days
- Under 5% in 90–120 days
