AR days formula to calculate Average AR days in medical billing

The AR days formula is valuable for healthcare businesses because it calculates the average number of days it takes to receive reimbursement. 

Practices that are not involved in regular AR days calculations result in revenue loss, delayed payments and unsatisfied patients. 

Hence, to enhance your business’s revenue efficiency, get deeper knowledge of AR days, the a/r days formula, and the simplified AR process in medical billing.

What is AR in Medical Billing?

The AR full form in medical billing is accounts receivable. It refers to the money owed by payers and patients to the healthcare provider for rendered services. The most popular AR amounts included in billing are:

  • Outstanding insurance claims
  • Patient balances
  • Pending reimbursements

An AR days calculation metric is important in medical billing because it indicates a practice’s financial health and ability to generate revenue. 

What are Days in AR (Accounts Receivable Days)?

AR days, also known as Days Sales Outstanding (DSO) or Debtor Days, are a key financial metric indicating how efficiently a business manages its revenue. Despite their many names, they measure the average time it takes to convert receivables into cash. 

In other words, if DSO time is low, it means the client pays on time, and the company’s cash flow is strong. However, if days in accounts receivable get longer, payment collection is delayed, which increases the financial pressure on the business. 

How to Calculate AR Days

AR days calculation is important for a healthcare business to analyze the cash flow and financial health. Practices that want to calculate AR days need to follow an AR process in medical billing, which includes:

Understand what AR days represent

Learn what a/r days show. Generally, it means the average number of days it takes for your company to collect payment after issuing an invoice. Lower days mean higher reimbursement, while longer days mean financial pressure.

Gather Financial Data

Collect key financial metrics to understand the business’s financial track. These include.

  • Total accounts receivable (From your balance sheet)
  • Total net credit sales (from your income statement)
  • The time you want to measure (usually annually or monthly)

Use a consistent time frame

Ensure the accounts receivable and credit sales are gathered within the same time frame. For instance, both are gathered from the past 12 months.

Apply the formula

After you’ve collected the data and the timeframe, you can calculate it using the standard a/r days formula. 

AR Days Formula with Example

The AR days formula is a financial mapping metric in medical billing that shows how long it takes a practice to collect revenue from a patient or insurer after delivering service. It helps measure the efficiency of the revenue cycle. The standard formula for days in AR calculation for healthcare is: 

AR Days = Total Accounts Receivable ÷ Average Daily Charges

  • The Total Accounts Receivable = The outstanding payment from insurance companies and patients.
  • The average daily charges = Total charges over a given time ÷ Number of days in that time period.

Here’s an example showing how to calculate AR days in medical billing. Imagine a clinic with $90,000 in accounts receivable and $270,000 in billed amounts over the past 90 days. The average daily charges would be 3,000$ as by ($270,000 ÷ 90). Now, by using the AR days formula in medical billing.

AR days = $90,000 ÷ $3,000 = 30 days

This means the clinic typically takes 30 days on average to receive payment for a service delivered. The ratio below 40 days means the practice’s revenue cycle efficacy is good, and it maintains a steady cash flow and financial health.

How Do Longer AR Days Impact Reimbursements?

Longer a/r days impact the healthcare reimbursement process by disturbing the cash flow, increasing the risk of bad debt, and through negative financial metrics. Here’s the detailed elaboration of deeper impacts.

How do Longer AR days impact reimbursements

Disruption in Cash Flow

When longer days in ar are common, many practices feel intricate in covering operational costs such as salaries, rent, equipment and vendor payments. This leads them to rely on credit and emergency funds to get on track in business, ultimately pushing the practices to financial stress, and reducing the investment in business growth.

Increased Risk of Bad Debt & Write-Offs

The longer the claim or patient balance goes unpaid, the greater the chances of practices being written off as bad debt. In other words, the unpaid payments for 90 to 120 days ruin profitability and increase the administrative burden through unnecessary collections. 

Negative Financial Metrics

Longer days in accounts receivable result in slowed reimbursement, making it harder for providers to achieve a sustainable profit margin. The negative financial metric leads to businesses being stuck in revenue growth and lower patient satisfaction.

What Causes an Increase in Accounts Receivable Days?

A company’s receivables, which represent money owed by its customers for goods or services, increase the AR days due to various factors. These include denied claims, lack of AR audits, and slowed insurance payments.

Causes of Increase in Accounts Receivable Days

Lack of AR Audits

If a practice misses the regular accounts receivable days calculation audits, it may result in missing priority claims and unresolved denials. This means the old claims may go unnoticed, which consistently increases AR days and delayed collections.

Delays in Patient Payments

When patients are not reminded in time about their unpaid balance, the payment process may take weeks or months. High out-of-pocket costs or unclear billing statements are common reasons why patients refuse to pay their portion of the payment, increasing the days in accounts receivable healthcare.

Claim Denial or Rejection

Claim errors, such as coding errors, missing information or eligibility issues, lead to denials. As the claim denials are repeated, more days are added to the correction process, ultimately adding more days to AR.

Slow Insurance Payments

Even when a claim is processed without error, many insurance companies still take weeks or months to reimburse the provider. This kind of payment delay is not in the provider’s control, but it still affects the AR days in medical billing.

Best practices to shorten AR days in medical billing

Best practices such as clear claims, timely billing, and better payer negotiations could reduce the AR days and improve the healthcare revenue cycle. Here are the key points to follow to shorten days in AR.

Best practices to shorten AR days in medical billing
  1. Timely billing: Submit claims as soon as the service is offered to the patient, and the reimbursement will be quicker, resulting in fewer A/R days.
  2. Reveals Payment Delays: Timely use of the AR days formula identifies payment loopholes and corrects specific problems, such as payer lag or internal processing delays.
  3. Clear and Concise claims: Accurately documented claims with accurate codes and compliant with payer guidelines, reduce claim denials and AR days.
  4. Efficient patient communication: More open discussions with patients before rendering service ensure reduced days in accounts receivable healthcare by enabling patients to understand their financial responsibility.
  5. AR days monitoring: Monitor and analyze AR days on a 3-month basis to identify areas of change and implement changes to reduce AR days.
