EOB is generated by the Insurance Company (payor) when the provider submits a claim for the services provided by him to the patients. Two to three weeks after claims submission, the medical practitioner receives a reply from the payor in the form of EOB. This is to inform them about their decision as to whether the claim will be paid or denied. The provider receives the EOB via traditional mail.   If there is a payment associated with the EOB, it will be sent as a check via traditional mail by the Insurance to the service provider (Clinic). If the EOB states that the claim was denied, the clinic billers are required to take further action like resubmission of information to the Insurance company.
