The percentage of charges that can be billed to multiple insurance policies should not exceed what?

When considering the percentage of charges that can be billed to multiple insurance policies, it is crucial to understand the concept of coordination of benefits (COB). In instances where a patient has more than one insurance policy, the total amount billed across all policies should not exceed 100% of the charges incurred for a service. This is to ensure that the total reimbursement does not surpass the actual cost of the services rendered.

Billing 100% allows for the appropriate distribution of claims among the different insurers while adhering to legal and ethical standards in billing practices. This prevents instances of overbilling, which can arise if the total reimbursement were to exceed the actual service cost, leading to complications and potential legal issues for healthcare providers. Therefore, the correct percentage is 100%, as it represents the full coverage of the incurred charges without exceeding them.
