AR in Medical Billing: Best Practices to Improve Cash Flow

Cash flow challenges in the medical practice will hardly ever begin because there is not enough of either patients or billable services. In most cases, cash flow issues arise because of ineffective management of AR in medical billing. The practice, in this case, fails to act on the claims fast enough, to resolve denials and receives payments much slower than the practice makes expenses. Understanding the meaning and principles of active management of AR in billing is crucial for all medical facilities aiming to remain solvent.

This guide is aimed to help you understand the meaning of AR in medical billing, the importance of its management for cash flow, and best practices used by top-performing billing teams.

What Is AR in Medical Billing?

Without further ado, it's useful to start by addressing the basic question of what exactly AR in medical billing is.

In the realm of medical billing, accounts receivable (AR) is the sum of money that is still owed to the healthcare provider for the procedures that were provided but haven't been paid yet. It includes both payments due from the insurance payers (Medicare, Medicaid, or other health insurances) and payments due from the patients themselves (copays, deductibles, coinsurance).

Why AR Management Directly Affects Cash Flow

When a healthcare service is provided, it can create a receivable that remains outstanding until the payer or patient makes payment. The time between service delivery and collection affects the practice's cash flow. 

Mismanagement of AR in medical billing results in the following domino effect:

• Delayed payment of payroll and vendors. The practice has a hard time covering its operational expenses as the money that has been earned is not yet collected.
• Limited ability to invest. The money that should have been spent on hiring employees, purchasing equipment, and other initiatives stays tied up in AR.
• Increased amount of write-offs. The later the money is collected from the patient, the bigger is the chance for the practice to fail in collecting the money at all due to the time limits for filing the claim or limited effectiveness of efforts.
• Deteriorated relationship with lenders. If the practice uses lines of credit to cover cash flow gaps, it has to pay more interest to the bank the longer AR days last.

That is why managing the revenue cycle, experts are tracking AR in medical billing as diligently as they are tracking patients' visits or other metrics.

Key AR Metrics Every Practice Should Track

You can’t improve what you can’t measure. Below are key performance indicators associated with AR management in medical billing:

• DAYS IN AR: A common industry benchmark is to maintain days in A/R around 30-40 days, although appropriate targets vary by specialty, payer mix, and practice type.
• AR aging buckets: What proportion of total AR falls into each age bucket (0-30, 31-60, 61-90, and over 90 days old). The ideal AR structure has a very high percentage in the 0-30-day bucket.
• Net collection rate: Percentage of allowed revenue collected; it shows how well a practice collects what it should be collecting.
• Denial rate: Percentage of claims initially rejected; one of the main sources of AR aging problem due to non-action.
• First pass resolution rate: What percentage of claims is paid in full and in accordance with the first submission.

Monitoring these KPIs helps billing departments to early warning system, flagging AR problems before they become cash flow emergencies.

AR Denials in Medical Billing: The Biggest Threat to Cash Flow

Claim denials are a major contributor to delayed reimbursement and aging accounts receivable. Denial of a claim does not make the claim go away; rather, it remains in the AR, pending resolution of the denial and resubmission of the claim.

The following are some of the reasons why a claim may be denied:

• Eligibility and coverage problems – The insurance policy of the patient was no longer valid, or the service being billed was not covered by that particular plan.
• Coding errors – Errors in the use of CPT, ICD-10, and HCPCS codes or lack of modifiers
• Documentation errors – Lack of medical necessity documentation for the service being billed
• Timely filing errors – Timely filing limits vary by payer and contract. For example, Medicare generally requires claims to be filed within 12 months of the date of service, subject to applicable exceptions. 
• Lack of prior authorization for some of the services provided
• Resubmission of duplicate claims
• Errors in coordination of benefits – Sending of claims to the wrong payer because the patient had different insurance coverages

Unless they are addressed, denials will become the leading reason why AR ages beyond 90 days since at this stage, collectibility becomes very difficult. This is the reason why denial management, as opposed to just normal billing processes, is crucial for controlling the AR in medical billing.

Best Practices to Improve AR and Strengthen Cash Flow

1. Verify Eligibility Before the Visit

Coverage is one of the most common reasons why ARs are denied in medical claims processing, yet this can be avoided before submission. Ensuring insurance eligibility and benefits at check-in time, rather than during the denial stage, eliminates this class of AR problems.

2. Submit Clean Claims the First Time

Any claim that is sent out with errors results in rework, delays payment, and contributes to aged accounts receivable. Coding audits, claim scrubbing tools, and verification of documentation before sending the claim all help to minimize the number of returned claims.

3. Work Denials Immediately, Not in Batches

A rapid denial process is the key to minimizing AR. Denied claims need to be sorted based on the reason for denial and also their monetary value. The most critical denials, based on value and timeliness, must be handled first. Delaying action on denials causes them to pass beyond the point where they can easily be rectified.

4. Segment and Prioritize AR by Age and Value

Not all ARs should be treated equally. Billing staff need to focus on:

• Large value claims irrespective of how old they are.
• Near-timely filing cutoff claims.
• Ages 31 to 60 days when there is still hope of recovery.

Claims above 90 days have to be handled differently, such as through escalation, payer appeals, or write-off, as the probability of getting all the money back gets lower the older the claim remains outstanding.

5. Automate Where Possible

Follow-ups by manual means do not scale well in the face of rising numbers of claims. Automation of processes ranging from checking the status of claims through denial classification all the way to verifying eligibility allows the billing department to spend time only on the claims that require human attention, while the rest are handled in the background automatically. This is what more and more billing systems driven by artificial intelligence (AI) are achieving.

How Technology Is Changing AR Management

In the past, medical AR management in most organizations had been conducted largely using a manual process of staff reviewing aging reports, contacting payers, and entering denial reasons into spreadsheets. Such an approach finds it hard to cope with the rising number of claims, and this is why many organizations incorporate technologies into their AR management processes to:

• Use artificial intelligence to detect high priority denials and thus not require the staff to search through aging reports in order to determine the right course of action.
• Use predictive analytics to identify claims at higher risk of denial before submission by analyzing factors such as documentation, coding, and payer patterns, thus preventing claims from being denied and requiring them.
• Run continuous eligibility checks rather than just checking once upon patient check-in and thus detecting possible problems that could cause the denial of claims beforehand.
• Have a real-time AR dashboard and not wait until the end of the month to analyze aging, payer performance, and denials.
• Use RPA to perform repetitive tasks of status checks and payer portal lookups.

Automation can reduce repetitive work, but human oversight remains important for complex denials, payer-specific issues, appeals, and exceptions. However, the increasing amount of work done by automated systems has made sure that AR departments have the luxury of being able to concentrate on the cases which truly require their expertise.

Common Mistakes That Keep AR in Medical Billing High

Even well-meaning billing departments get into the habit of doing things that gradually contribute to bloated AR balances:

• Undervaluing denial management and leaving it as a low-priority activity. This way, it always gets pushed back to the end of the day after all other "normal" billing tasks have been done, and the denial becomes too old to be easily recoverable.
• No standard timeline for claims follow-up. If there are no guidelines on what is the appropriate period for following up with a particular claim, the claim will be neglected for weeks unnoticed.
• Data silos between coding, billing, and collections departments. The absence of communication between the departments results in repeated mistakes in coding or documentation in subsequent claims instead of addressing the mistake once and for all.
• No communication between denial analysis and clinical documentation. In the absence of feedback to the physicians or the coders about the denial trends, the preventable denials will continue to appear over and over again.
• Over-reliance on spreadsheets for managing AR. Spreadsheets do not scale and are prone to errors.

The Role of RapidClaims in the AR Process

The core issue with AR in the realm of medical claims lies in the timing; at the point where denial appears on the aging report, the documentation or coding error that caused the issue has cost the office days or even weeks in the process. The design of RapidClaims aims to address this issue in its earlier stages. Instead of addressing denials that occur later on in the cycle and working on them as part of the AR management process, RapidClaims uses AI in the coding process to identify common causes of AR issues, such as medical necessity, modifier mismatches, and documentation errors.

The Bottom Line

It is important to note that the increase in cash flow isn't achieved by way of seeing more patients or billing for more services but by ensuring that what has been earned is converted into cash flow as rapidly as possible. This is the fundamental purpose of AR in the context of medical billing: the handling of the time period between service provision and payment.

The effective monitoring of appropriate metrics, eligibility confirmation of patients, clean claims submission, addressing denials right away, and making sure that everyone knows what is expected of him in relation to AR will help significantly in reducing days in AR and securing the cash flow that is crucial for the business. A/R-related claim denials are claims or payment requests that a payer has rejected or denied, potentially delaying reimbursement and contributing to outstanding accounts receivable.
