Electronic Billing

Electronic Billing. It's fast and it's free!

Whether you submit one claim a month, or hundreds, any provider can benefit from switching from paper to electronic billing. Whether by using the free WINASAP2003 software or by using a clearinghouse to submit claims, electronic billing is faster, more accurate, and more secure. Electronic claims can be processed for payment in as little as a week versus three to four weeks to process a paper claim. All you need is a personal computer (Windows 98 and above) and a standard phone line to submit electronically via WINASAP2003.

In only three easy steps, you can be set up to submit your Medicaid claims electronically.
