What does COB mean in Medical Billing?
Coordination of Benefits or COB determines which insurance company pays for medical expenses when someone has multiple insurance policies. It’s important to avoid overpaying, and the primary and secondary insurance coverage is determined to ensure total benefits don’t exceed the charges.

How does COB work?
COB typically follows rules and guidelines to determine how insurance plans should be billed. These rules can vary depending on the type of insurance coverage, such as employer-sponsored plans, Medicare, or Medicaid.
Here are some common scenarios that illustrate how it works:
- Dual insurance: Patient has two insurance plans; the primary is billed first, remaining charges are submitted to the secondary.
- Non-duplication of benefits: Combined benefits shouldn’t exceed total charges; secondary covers the remaining amount or patient’s share.
- Order of liability: Determines which plan pays first based on factors like age or employment. A coordination period may apply.
What is the purpose of the COB process?
Its goal is to ensure that people with multiple insurance policies receive proper coverage and avoid unnecessary costs. Determining the order in which insurance plans pay medical expenses, maximizes patient benefits, prevents overpayment, and reduces financial burdens. This process benefits both patients and healthcare providers by establishing a clear insurance coverage hierarchy and minimizing claim rejections.

In certain scenarios, Medicare assumes the role of the primary payer, ensuring coverage and benefits for individuals. Let’s explore these unique circumstances:
- Workplace-aged and employer Group Health Plan (GHP): If you’re 65 and have a GHP, Medicare is the primary payer. If your employer has <20 employees, Medicare is primary. If >20 employees, Medicare is secondary.
