Hi! I’m a detail-oriented and reliable Medical Biller with hands-on experience in insurance claims, AR follow-up, denial management, and payment posting. I help healthcare providers get paid accurately and on time by making sure every claim is clean, complete, and compliant before it goes out the door. I also have experience using practice management tools such as Tebra, SimplePractice, and Athenahealth. Whether it’s fixing a denial, rejections, or tracking down missing documentation, I always follow through until the claim is fully resolved. I’ve worked with a wide range of payer and I’m comfortable navigating payer portals such as Availity. I communicate clearly, stay on top of deadlines, and treat every task with care because I know how much smooth billing impacts the whole practice.
