Days in Accounts Receivable (AR) is one of the most important performance indicators in medical billing and revenue cycle management (RCM). This metric measures the average time it takes for a healthcare provider to collect payments after services have been rendered.

When days in AR increase, cash flow slows, operating costs rise, and maintaining financial stability becomes more difficult. Conversely, a lower number of days in AR reflects a healthy revenue cycle, efficient billing processes, and faster reimbursements.

In today’s healthcare environment where claim denials and payer requirements are increasingly complex reducing days in AR is crucial for maximizing revenue and maintaining profitability.

This guide explains what days in AR are, why they matter, and the most effective strategies healthcare organizations can use to reduce them.

What Are Accounts Receivable (AR) Days?

Days in accounts receivable represent the average number of days it takes a healthcare organization to collect payments from insurance companies and patients..

AR Days Formula

Days Sales Outstanding = Total Accounts Receivable ÷ Average Daily Charges

This metric helps providers evaluate the efficiency with which revenue moves through the billing and collection process.

Why AR Days Matter

A high number of accounts receivable (AR) days often indicates issues within the revenue cycle, such as:

1. Delays in claim submission
2. Coding errors
3. Issues managing denied claims
4. Slow processing by payers
5. Ineffective collections management
6. Inaccurate patient information
    

Reducing AR days offers several advantages:

1. Improved cash flow
2. Faster reimbursements
3. Reduced administrative costs
4. Lower claim denial rates
5. Better financial forecasting
6. Increased profitability
    

For many practices and health centers, keeping AR days below 40 is considered an indicator of strong performance.

Common Causes of High AR Days

Before reducing days sales outstanding, suppliers must understand the factors contributing to payment delays.
 

Insurance Verification Errors

Incorrect eligibility information often leads to claim rejections and payment delays.
 

Medical Coding Mistakes

Coding errors often lead to denials, requiring corrections and resubmissions.
 

Delayed Claim Submission

The longer a claim remains unbilled, the more the reimbursement will be delayed.
 

Poor Denial Management

Unresolved denials can significantly increase outstanding accounts receivable.
 

Inefficient Follow-Up Processes

The lack of consistent follow-up with payers and patients slows down collections.
 

Patient Payment Delays

The increasing financial responsibility of patients can prolong collection periods.

Proven Strategies to Reduce Accounts Receivable (AR) Days
 

1. Verify Insurance Eligibility Before Every Visit

One of the simplest ways to reduce days in accounts receivable is to ensure insurance coverage is verified before services are provided.

Eligibility verification confirms:

1. Active coverage
2. Copayment amounts
3. Deductibles
4. Authorization requirements
5. Policy limitations
6. Benefits
7. Fewer claim rejections
8. Faster claim processing
9. Reduction in billing errors

2. Submit Claims Quickly

Delays in claim submission directly increase days in accounts receivable.

Healthcare organizations should aim to submit claims within 24 to 72 hours of the date the service was provided.

Best Practices

1. Automate charge capture
2. Reduce documentation delays
3. Establish daily billing workflows
4. Monitor claim submission deadlines
    

Faster claim submission accelerates the reimbursement cycle.

3. Improve Medical Coding Accuracy

Accurate coding plays a fundamental role in reducing accounts receivable (AR) days.

Common coding issues include:

1. Incorrect diagnosis codes
2. Missing modifiers
3. Incomplete documentation
4. Use of outdated codes
    

Solutions

1. Hire certified coders
2. Conduct periodic coding audits
3. Use coding software
4. Offer ongoing training
5. Error-free claims expedite approval by payers.

4. Focus on Clean Claim Submission

A clean claim contains all the required information and is accepted on the first submission without errors.

Benefits of Clean Claims

1. Faster reimbursement
2. Lower denial rates
3. Reduced administrative burden
4. Improved cash flow
    

Improvement Strategies

1. Use claims scrubbing technology.
2. Validate patient information.
3. Review the specific requirements of each insurer.
4. Periodically audit claim quality.
    

Practices with high rates of accurate claims generally experience a lower number of days in accounts receivable.

5. Strengthen Denial Management

Denied claims contribute significantly to the aging of accounts receivable.

Each denied claim must be:

1. Investigated promptly
2. Corrected accurately
3. Resubmitted quickly
4. Monitored until resolution
    

Best Practices

1. Monitor denial trends
2. Categorize denial reasons
3. Create denial prevention strategies
4. Establish teams dedicated to denial management
    

Effective denial management significantly reduces the aging of accounts receivable.

6. Prioritize AR Follow-Up

Constant follow-up is essential for collecting outstanding balances.

Billing teams should prioritize claims based on:

1. The age of the debt
2. The claim value
3. The payer's responsiveness
4. The denial status
    

Recommended AR Aging Review

1. 0–30 days
2. 31–60 days
3. 61–90 days
4. 91–120 days
5. Over 120 days
    

The oldest claims require immediate attention to prevent them from being written off.

7. Monitor Payer Performance

Not all insurance companies process claims at the same speed.

Tracking payer-specific metrics helps identify:

1. Slow-paying insurers
2. Payers with high denial rates
3. Reimbursement delays
4. Contractual issues
    

Key Metrics

1. Average payment processing time
2. Denial rates by payer
3. Appeal success rates
4. Frequency of underpayments
    

Understanding payer behavior improves collection efficiency.

8. Improve Patient Collections

Patient financial responsibility continues to rise due to higher deductibles and copayments.

Healthcare organizations must collect outstanding patient balances as soon as possible.

Effective Strategies

1. Collect copays at the time of registration
2. Offer online payment options
3. Facilitate payment plans
4. Send automated reminders
5. Provide transparent billing estimates
    

Collecting payments upfront reduces outstanding patient balances and days in accounts receivable.

9. Utilize Revenue Cycle Management Technology

Modern invoicing technology helps automate many processes that contribute to speeding up collections.

Useful Technology Features

1. Automated eligibility verification
2. Electronic claims submission
3. Real-time claims tracking
4. Denial analysis
5. Revenue dashboards
6. Online portals for patient payments
    

Automation improves efficiency while reducing manual errors.

10. Track Key AR Performance Metrics

Reducing days sales outstanding requires continuous performance monitoring.

Key performance indicators (KPIs) include:

Days in Accounts Receivable

It measures the overall efficiency of collection.

Clean Claim Rate

Indicates the percentage of claims accepted without errors.

Denial Rate

Track rejected claims that require correction.

Net Collection Rate

It measures what proportion of collectible revenue is actually collected.

First-Pass Resolution Rate

It shows how many claims are paid upon first submission.

These metrics help identify areas for improvement before they impact revenue.

AR Aging Best Practices

Healthcare organizations must establish clear objectives for managing accounts receivable.
 

Target Benchmarks

1. Less than 15% of accounts receivable aged over 90 days
2. Days Sales Outstanding (DSO) under 40
3. Clean claim rate above 95%
4. Denial rate below 5%
    

Regular monitoring helps maintain healthy cash flow and strong revenue cycle performance.

The Role of Outsourced AR Management

Many healthcare providers choose to outsource accounts receivable follow-up and collections management to companies specializing in medical billing.

Benefits include:

1. Dedicated accounts receivable specialists
2. Faster claim resolution
3. Improved collection rates
4. Reduced staffing costs
5. Greater success in recovering denied claims
6. More comprehensive reporting
    

Outsourcing allows providers to focus on patient care while experienced professionals manage outstanding accounts.
