Here's the answer to your question: What are the benefits of electronic claims filing?
Electronic claim filing is more efficient and cost effective. You no longer have to keep track of or file paper claims, and you receive confirmation of receipt of your claim within one day of filing the claim. You will also be promptly notified if a claim has not been completed properly for processing and payment. And lastly, filing online claims using the browser-based application is free to providers that have secure access to the Magellan provider website.
