Out of pocket pay discounts

[Guest guest]

Once we bill a clients insurance and the insurance makes their 80%

payment can we give a client a discount on the 20% that they owe? The

insurance paid better than others that we bill and more than covered

what we need but did not cover what we asked for. We billed $180 and

Insurance paid $144. We are satisfied with the $144 but want to do the

right thing. Any help would be appreciated.

Thanks
