EZClaim medical insurance billing software can send electronic claims directly (not through a clearinghouse) to all payers or processors that accept claims using the ANSI 837 format. This medical insurance billing includes: medicare, Medicaid, Blue Cross/Blue Shield, THIN - Texas Health Information Network, and all other payers or processors that accept claims using the ANSI 837 format. Although the optional direct medical insurance billing module allows for submitting directly to a large number of companies, it is important to be aware that most commercial insurance companies, Ex: Aetna, Humana, do not accept direct electronic submission. You, as the provider, need to contact the company to ask if they accept direct electronic medical insurance billing submission.
