In this era, medical billing has become an emergent complicated issue in the healthcare industry. It requires special billing, coding, and Account Receivable (AR) management skills. The financial stability of healthcare organizations depends upon positive cash flow. It is also required to manage expenses required for managing costs incurred during patient care. The presence of trained coding and billing staff and following insurance guidelines can benefit from a smooth revenue cycle flow. However, sometimes, when everything goes smoothly still, many claims are denied or rejected and never reworked. Delay in filing the claim for reimbursement could be a fundamental reason. It happens during the loss of a paper claim instead of delivering electronically to an insurance company.
