Coordination of Benefits (COB) issues can be a thorn in any medical billing team's side. They can stall reimbursement, trigger denials, and lead to patient frustration. But these issues are unavoidable—especially with patients carrying multiple insurance plans. Here’s how to cut through the clutter and handle COB issues with finesse.
Determining Payer Order
First things first: order matters. The primary payer is the insurance company that pays first. Secondary payers pick up what the primary does not cover. Getting this order wrong invites a world of denials.
The Birthday Rule
For dependent children with dual coverage, the Birthday Rule often applies. This rule states that the parent whose birthday falls first in the calendar year usually has the primary plan. But there are exceptions. Court orders, for instance, can override this rule. Double-check the patient’s plan details if a court order is involved.
Medicare as Secondary
Medicare usually acts as a secondary payer when another insurance is present. However, it's not always straightforward. If the patient is actively working and covered by an employer group health plan, Medicare will take a back seat. Don't assume—verify every time.
Correcting COB Denials
COB denials are frustrating but fixable. Often, the problem lies in incorrect information or payer order errors. Resolve them swiftly to keep the revenue flowing.
Identify the Denial Code
Denial codes like CO-22 (indicating non-covered charges) often tie back to COB issues. These codes are your first clue. Understand what they imply and act accordingly.
Gather Documentation
Documentation is your best friend. Collect all relevant information about the patient's insurance plans and any correspondence related to their coverage. This includes explanation of benefits (EOB) from the primary payer. Without this, appealing denials can become a nightmare.
Contact the Payer
Call the payer—yes, there's often a long hold time, but it beats the alternative. Confirm details like coverage dates and payer order. Payer portals may offer some answers, but human confirmation is often necessary to resolve complex COB issues.
Managing Dual Coverage
Handling dual coverage efficiently can prevent many COB headaches before they occur. It's all about keeping your ducks in a row.
Detailed Patient Intake
Get as much information as you can at the start. During patient intake, ask for comprehensive insurance details—policy numbers, group numbers, and coverage dates. Redundancy here saves time later.
Regular Verification
Insurance details can change, sometimes without notice. Perform regular insurance verifications, especially before significant procedures. This isn’t just busywork—it prevents unnecessary denials.
Update Your System
Ensure your billing system reflects the current coverage details accurately. Incorrect or outdated information is a common cause of COB denials. Regularly audit your records to catch errors before they manifest as denied claims.
Educate Your Team
Training your billing team on COB protocols is non-negotiable. They should know the ins and outs of payer rules and the importance of order. Familiarity with common denial codes and their meanings is crucial.
Dealing with Payer Quirks
Every payer has its quirks. UnitedHealthcare might have different portal features compared to Blue Cross Blue Shield, impacting how COB issues are managed. Your team should know these idiosyncrasies.
Utilize Payer Portals
Portals can be a treasure trove of information—if you know how to navigate them. Some may offer real-time updates on claim status or coverage plans. Make sure your team is trained to use these tools effectively.
Keep Notes on Payer Preferences
Keep an internal document that tracks quirks and preferences of different payers. This should include preferred communication methods and any recurring issues. This living document can save your team time and frustration.
Looking Ahead
COB issues are never going away, but they can be managed more effectively. By understanding payer order, correcting denials quickly, and managing dual coverage proactively, practices can reduce the frequency and impact of COB issues.
The takeaway? Diligence in the details. Keep lines of communication open with payers and patients and ensure your team is well-versed in COB intricacies. Fewer denials, happier patients, and a healthier bottom line will follow.
