You can begin sending electronic claims to all commercial insurance companies, such as Aetna, Cigna, United Healthcare, and many others, within 48 hours of signing up for Octopus. A few payers, such as Medicare, Medicaid, Blue Cross/Blue Shield, may require authorization of an enrollment form before you can submit electronic claims.
