Denial management is a vital component of revenue cycle management in medical billing process. Denial Management is to investigate every unpaid claim and appeal the rejected claims appropriately. It demands extensive knowledge and timely execution. ABCLLC have a well-experienced team of denial professional trained to identify the root cause of expensive denials. Our dedicated and skilled denial professionals can handle denial efficiently and in a timely manner to minimize denials reimbursements. ABCLLC  correct and resubmit the claims and file an appeal towards deemed medically not necessary claims. The appeal letter is sent to retreat the payer for their mistakes and make them clarify why the original processing of the claim was incorrect. Systematic tracking of denials will collect data back to the billing process to prevent future denials of the same nature, thus ensuring first submission acceptance and payment of claims. Denial Management team helps you to take control of your denials and accelerate reimbursements.
