What is DSO and How Do You Reduce It?

The chances are that the DSO keeps you awake at night if you are handling a multi-site dental practice. What does DSO mean, and what does it take to improve liquidity? A lower Days Sales Outstanding (DSO) means effective collection practice. Without the healthy revenue cycle, there is a deviation in the care.

The American Dental Association and Dental Economics mentioned that 30 to 45 days of DSO are in the United States. The red zone for DSO is staffing gaps, rising denials, and slow payments, indicating practice cash has been inconsistent, and there is a problem down the line.
The requirement is obvious: reduce DSO to a substantial number without delaying patient treatment and staff burnout. Modern automation and proactive collection strategies are a contributor across the U.S. According to the ADA Health Policy Institute (2022), most dental practices that have automated solutions have seen a lower DSO of up to 12 percent, which can add to the cash flow.

Reimbursement is unstable, with changing payer rules and overworked employees, leaving no room for error. According to the CAQH Index (2023), automating administrative transactions, such as real-time eligibility, can save time. Saving minutes in a dental DSO where thousands of encounters can make a difference in faster billing. Reducing DSO builds healthier AR and a better patient experience.

What does DSO mean, and what does it mean to reduce DSO days?

Reducing days' sales outstanding indicates that payment collection is faster for the services rendered. Improved cash flow, minimized bad debt, and ample opportunities result in lower DSO. A dental practice can successfully minimize its accounts receivable follow-up time by working with a reliable partner like Capline Dental Services. The significant reduction can lead to improved financial operations.

What does DSO mean, and how to work around the challenges?

AR divided by daily credit sales is how DSO is calculated. However, a footnote with plan limitations, payers' rules, predeterminations, attachments, and document peculiarities. It means different codes and different logics that drag out the revenue cycle.

Unnecessarily high DSO can be because of the following reasons:

  • Eligibility surprises and incomplete coverage data lead to rebilling, delays, and rework.
  • Denials and delays are certain to happen if missed attachments, like perio charting and radiographs, are not submitted at the initial submission.
  • Manual claim follow-up adds up to the lost productivity and slack time.
  • Reworking the recurrent patterns shows a lack of structure in the denial queue.
  • Rejections are a part of the process where there is fragmented communication in the CDT coding and clinical narratives.

Some denials are avoidable. The underlying causes are missing information, coding, and eligibility, which are highly preventable. Backing it, 86 percent of denials are avoidable by Healthcare’s Denial Index (Medical 2020). Professionals stress long DSO because it restricts growth. The inconsistent cash flow does not allow investment in hiring and new technology. The team is busy with low-value tasks.

What does DSO mean? Let’s comprehend the solution!

Reducing the DSO blend through several approaches, including automation, standardized workflows, and anticipatory measures. It is not a fluke. Eligibility and benefits checks are conducted ahead of the visit and on the day of service to get a fresh perspective. Particularly focus on the frequency limitations and waiting periods to get an accurate estimation that improves time-of- service collections.

A clean claim can alter the direction of revenue. The ADA requires that each denied and rejected claim be reworked. The administrative expenses are roughly $25 to $30. Initial denials can be prevented through the documentation templates. Trigger denials can be minimized; otherwise, there is a 17 percent chance that the claim will be delayed by more than 30 days, as per SIKKA’s report (2022).

Claim aging is not a good sign and can be automated across portals. Working systematically with the aged AR to resolve problems and provide an outcome. Easy RCM nudges claims forward to encourage compliance.
The major impact is from manual to automation when trying to reduce DSO. The changes ensure real-time verification, claim submissions, claim tracking, and claim resolution.

The plan to reduce DSO days includes:

  • Defining metrics, such as average daily credit sales, as per practice, payer, and provider. AR aging percentage highlights several denominators touching per claim.
  • Review the list of flaws, the frequency of updating eligibility data, and whether the estimate is shared with the patient. What is the status of claim denials, and how often are they tracked?
  • Investing in a high-ROI automation can show faster results. Configure with Capline Services experts for customized solutions.

What does DSO mean, and what are the roadblocks?

Dysfunctional processes, inconsistent documentation, and coding errors result in faster failure.

  • Practice cannot disregard the patient portion at the time of service. It inflates DSO and moves it to backend AR.
  • Misses specific evidence about particular procedures, such as crown, SRP, that keep delaying the payment.
  • Delay in follow-up is a long chase that eventually turns into aging.

Let’s explore some frequently asked questions and answers to achieve a positive outcome.

Are the DSO days being reduced, and how long does it take to see results?

Expedited payment collection means reduced DSO days. To have an efficient claim submission process that automatically takes care of the denials quickly, lowering the number of outstanding days.

Initial improvements are reflected within weeks with better claim acceptance rates and reduced follow-up tracking. Two to four weeks is the initial gauge of progress. The significant changes are observed within 90 to 120 days.

Is DSO reduction a competitive edge?

The stretch is based on the tools and processes implemented to set up the business. The return is sizable. Dental practices have higher cash flow, no non-recoverable debt, and strategic scheduling, reducing manual labor. Increased profitability brings success in the dental industry.

What can a dental practice expect when reducing DSO days?

Improved billing cycle, acceleration in collections, lower costs, happy patients, and fewer write-offs. Investment in new technology and advanced equipment ensures minimal disruption in patient treatment.
