Coordination of Benefits (COB) in Dental Insurance:

At CareRevenue, we’ve helped numerous dental practices across the U.S. resolve COB issues efficiently, and in this blog, we explain why COB is more than just a billing formality—it's a cornerstone of effective dental RCM in the US.

What is Coordination of Benefits (COB)?

Coordination of Benefits (COB) is the process used by insurance companies to determine the order in which multiple carriers should pay when a patient has more than one insurance policy. The objective of COB is to avoid duplicate payments and ensure that the total benefits paid do not exceed 100% of the service charges.

A Common Scenario:

A patient is covered by two dental plans—one through their employer and another as a dependent on their spouse’s plan. Which insurance pays first? COB rules define that hierarchy.

The primary insurance is the one that pays first, followed by the secondary, which may cover remaining costs up to the maximum allowable amount. Understanding this structure and applying it correctly can make or break your claim’s success.

Why COB Should Be a Priority in Dental RCM

1. Minimizes Claim Denials

Incorrect or missing COB information is one of the most frequent reasons for claim denials. When practices send a claim to a secondary payer without proof that the primary has paid—or fail to update the COB status—insurance companies may reject the claim outright.

At CareRevenue, we’ve seen how simply updating COB data can turn previously denied claims into successful reimbursements. Ensuring COB is confirmed during the patient intake process helps keep your claims on track.

2. Accelerates Reimbursements

Each delay in a claim cycle affects your **Days Sales Outstanding (DSO)**—a key performance metric in dental RCM. Proper COB handling eliminates unnecessary back-and-forth between insurers and the practice, reducing the claim lifecycle and speeding up cash flow.

3. Protects Revenue Integrity

COB missteps lead to revenue leakage—money you're rightfully owed but never collect. For example, a patient may have secondary coverage that could cover a co-pay or deductible, but without accurate COB details, that payment is never recovered. That’s lost income.

At CareRevenue, we use robust claim tracking and COB validation methods to ensure every eligible dollar is collected, improving overall dental RCM efficiency.

4. Reduces Administrative Burden

COB-related issues often create a ripple effect. Staff must chase down patients for information, spend hours on calls with insurers, and resubmit denied claims. Over time, this inefficiency adds up in both time and money.

By incorporating real-time COB verification and staff training into your practice’s front-office workflows, you can significantly reduce administrative strain—something CareRevenue implements in every partner practice.

5. Enhances Patient Experience

Imagine telling a patient weeks after their visit that a claim was denied because of outdated insurance info. It erodes trust and impacts retention.

Proactive COB validation at check-in and seamless handling of secondary claims ensures patients are billed correctly, which in turn boosts satisfaction and positions your practice as organized and trustworthy.

Common COB Situations in Dental Practices

1. Dual Coverage from Employer and Spouse
   COB often follows the “birthday rule”—the plan of the parent whose birthday comes first in the calendar year is considered primary for dependent children.
2. Coordination with Medical Insurance
   In rare cases, some procedures billed through medical insurance first (e.g., TMJ treatments) may require additional COB clarification.
3. Retirees or Veterans with Dual Plans
   Medicare, TRICARE, and employer coverage may all be involved, requiring careful attention to COB logic.

Each situation demands clear documentation and correct claim routing, something a skilled dental RCM team can manage effortlessly.

Best Practices for Managing COB Efficiently

At CareRevenue, our COB protocols are built to be proactive and precise. Here are some of our top strategies:

1. Verify at Every Visit

Insurance statuses can change between visits—employers change plans, patients get added or dropped. Always verify COB details at check-in, not just during annual updates.

2. Train Front Office Staff

Equip your staff with knowledge about primary vs. secondary insurance determination rules. A quick clarification at check-in can prevent weeks of delay down the road.

3. Use Technology Wisely

Leverage your PMS system to track COB data and integrate with clearinghouses for real-time eligibility checks. CareRevenue partners with practices using systems like CareStack, enabling automated COB tracking and cleaner claim submissions.

4. Maintain Clear Documentation

When COB questions arise, proper notes in the patient file—such as primary/secondary payer, effective dates, and EOB records—can speed up resolution.

5. Work with a Dental RCM Partner

COB is just one piece of the larger revenue cycle puzzle. By outsourcing to a dental RCM expert like CareRevenue, your practice gains access to billing specialists, payer relationship managers, and real-time dashboards to ensure every dollar is accounted for.
