Claims Submission involves submitting completed claims through the practice management system. The claim is submitted via a clearinghouse to a payer. Some cloud-based revenue cycle systems have direct interfaces with most leading insurance companies. We submit claims daily on behalf of the healthcare providers and combine them with any re-bill or secondary claims. Rebills are claims that are being resubmitted because there was an error on the first submission. We analyse the issues with first submission and strive to ensure that the issues do not recur. Secondary claims are claims that are submitted to secondary payers. This occurs when the patient has another insurance carrier in addition to a primary insurance carrier, and the practice has agreed to submit a claim to the patient’s secondary insurance company after it has received a portion of the payment from the primary insurance company.
