Detail-oriented Insurance AR Specialist with extensive billing experience.
What I'm looking for
I am a dedicated Insurance Accounts Receivable Specialist with over 20 years of experience in medical billing and authorization processes. My career has been marked by a commitment to accuracy and efficiency, ensuring that claims are processed correctly and in a timely manner. At On Time Ambulance, I excelled in reviewing EOBs for payment errors and submitting appeals for non-payments, which significantly improved our reimbursement rates.
Previously, I served as a Prior Authorization Specialist at Medical Diagnostic Associates, where I processed incoming authorization requests and verified patient insurance. My ability to identify authorization requirements and collaborate with clinical teams has been instrumental in streamlining operations. I have a proven track record of correcting billing errors and maintaining patient accounts, which has enhanced customer satisfaction and reduced delays in payments.
