It's All We Do

Successful management of the revenue cycle is a key component of a provider’s financial performance. One area of the revenue cycle that has been largely ignored is out-of-network bills. Yet with the rapid growth of out-of-network bills, insurance companies have become increasingly aggressive in reducing payment. Collect Rx can help you increase revenue by avoiding underpayments from third-party payors.
