Payment codes assigned as co-payments are handled differently than personal
payments or insurance payments.
You can review how your payment codes are set up in Review
a Payment Code or edit them in Maintain
Payment Codes.
A Co-payment differs from a personal payment and an insurance payment in
the following ways:
You can also enter co-payments through the Patient
Check In/Out function. These are stored as Unposted
Payments.
On the Payment Allocation screen, the co-payment amount automatically defaults
to the co-payment amount entered in the patients insurance record. If
you enter a Payment Code that has the Insurance
Payment Type set to Copayment and the Performing Doctor stored
for the procedure is set to Specialist, if a Spec Co-Pay amount is not
stored on the patient’s primary insurance policy, the amount stored for
the regular Co-Payment Amount will populate.

If you do not allocate the entire co-payment, you will receive a message
stating 'The amount of $ #.## will remain unallocated. Do you want
to post this payment?' Click Cancel if you want to continue
allocating the payment or click OK to save this payment.
