What does the coordination of benefits clause determine in group health insurance?

The coordination of benefits clause is an essential feature in group health insurance that dictates how multiple insurance policies work together when a claimant has coverage under more than one plan. The primary purpose of this clause is to establish which insurance policy will be responsible for paying first, thereby acting as the primary payer, and which policy will act as the secondary payer that may cover some or all of the remaining costs after the primary has paid.

This determination is crucial as it prevents the insured from receiving more than 100% of their healthcare costs covered, which could otherwise lead to fraudulent claims or excessive payouts. The rules outlined in the coordination of benefits clause ensure that the benefits are coordinated effectively, allowing for a structured approach to healthcare reimbursements and ensuring that all parties involved — including insurers, providers, and patients — understand their obligations and coverage limits clearly.

Other aspects of health insurance, such as premium amounts or eligibility for specific types of claims, are governed by different provisions in the policy documents, not the coordination of benefits clause. Additionally, while determining who should be the primary insured can be a consideration in some insurance practices, it is not the focus of the coordination of benefits clause.
