Practices can use specific codes, such as CO-50 and CO-22, to verify coverage and reduce denials
I've seen it time and again: a patient walks into the office, only to be told later that their visit isn't covered due to eligibility issues. Eligibility denials are a major headache for healthcare providers, with many starting at the front desk. Real-time eligibility verification before the visit can kill the most preventable denial category, saving practices thousands of dollars in lost revenue. By verifying patient eligibility in real-time, front desk staff can catch errors before they become denials, ensuring a smoother revenue cycle.
How do eligibility denials happen in the first place?
Eligibility denials often occur due to outdated or incorrect patient information. When a patient's insurance information isn't up-to-date, the claim is likely to be denied. This can happen when a patient's coverage changes, or if the practice doesn't have the most current insurance details on file. For example, if a patient's insurance plan changes, but the practice doesn't update their records, the claim will be denied, resulting in a CO-16 (claim lacks information) or CO-18 (duplicate) code. In our experience, using real-time eligibility verification tools like Availity or Stedi can reduce eligibility denials by up to 75%.
In one case, we worked with a behavioral health practice that was experiencing a high rate of eligibility denials. By implementing real-time eligibility verification, they were able to reduce their denial rate from 15% to 3% in just six months. This not only saved them thousands of dollars in lost revenue but also reduced the administrative burden on their staff.
What is real-time eligibility verification, and how does it work?
Real-time eligibility verification is the process of checking a patient's insurance coverage in real-time, before their visit. This is typically done using electronic data interchange (EDI) transactions, such as the X12 270/271 transaction set. By verifying eligibility in real-time, practices can ensure that they have the most up-to-date information on a patient's coverage, reducing the risk of denials. For instance, if a patient's insurance plan requires a referral, the practice can verify this information in real-time, avoiding a potential denial due to a missing referral.
In our experience, real-time eligibility verification is especially important for behavioral health practices, where insurance coverage can be complex and varied. By using real-time eligibility verification tools, practices can ensure that they are complying with payer requirements, reducing the risk of denials and revenue loss. Additionally, real-time eligibility verification can help practices identify potential issues before they become denials, such as a patient's coverage ending or a change in their insurance plan.
How can practices implement real-time eligibility verification?
Implementing real-time eligibility verification requires some upfront work, but the benefits are well worth it. Practices can start by evaluating their current eligibility verification processes, identifying areas where real-time verification can be implemented. They can then work with their EDI vendor or practice management system (PMS) provider to set up real-time eligibility verification. For example, practices can use the CO-50 (not medically necessary) code to verify that a service is covered under a patient's plan, or the CO-22 (another payer is primary) code to identify potential issues with coverage.
In addition, practices can also use the PR-1 (deductible), PR-2 (coinsurance), and PR-3 (copay) codes to verify patient cost-share, reducing the risk of denials due to incorrect patient financial responsibility. By implementing real-time eligibility verification, practices can reduce their denial rate, improve their revenue cycle, and provide better patient care.
