Understanding Coordination of Benefits (COB) in Health Insurance

Definition & Meaning

Coordination of Benefits (COB) refers to the process used by insurance companies to manage claims when an individual is covered by more than one health insurance plan. The primary goal of COB is to ensure that the total payments from all insurance plans do not exceed 100% of the medical expenses incurred. This process helps to prevent overpayment and ensures that both insurance providers share the financial responsibility fairly.

In practice, COB determines which insurance plan is considered primary and which is secondary. The primary plan pays first, covering its share of the costs, while the secondary plan may cover any remaining balance up to its limits. This coordination ensures that policyholders receive comprehensive coverage without exceeding allowable charges.

Real-world examples

Here are a couple of examples of abatement:

Example 1: A person who is covered by their employer's health insurance and their partner's plan becomes ill. The employer's plan is designated as the primary insurance, covering the initial medical expenses. Any costs not covered by the primary plan are then submitted to the partner's plan as the secondary insurance for additional coverage.

Example 2: (hypothetical example) A student covered under their parent's health plan and their own student health insurance may experience a similar situation where the parent's plan pays first, followed by the student's plan for any remaining balance.

State-by-state differences

State COB Rules
California Requires insurers to follow specific COB guidelines to prevent overpayment.
Texas Allows insurers to coordinate benefits but mandates clear communication of policies to insured individuals.
New York Has regulations that ensure timely payment of claims in COB situations.

This is not a complete list. State laws vary, and users should consult local rules for specific guidance.
