OA Online Bill Pay

For your convenience please use this option to make a payment towards your OA balance pertaining to any medical services. Please call (207) 828-2100 with any billing inquiries, unless these are related to services provided at OA Performance Center. For these inquiries, please call (207) 710-5509.

Please note that we changed our online processing merchant in May 2016. The payment screens look different.

The first screen asks you for your payment amount and a security code. The second screen asks you for your credit card information, Invoice No (meaning your OA Account Number), and the billing information for your credit card.

Clicking the - Pay My OA Invoice - button below will send you to the Authorize.Net secure web site where you can enter your payment amount, OA Account Number and credit card information.
