Before an account is placed with a collection agency, you will receive three billing statements from National Jewish Health advising you of your account activity. You will also receive two courtesy calls from the National Jewish Health billing office personnel regarding your balance(s) during this billing period. After these steps have been taken and payment or payment arrangements have not been made, the account is then referred a collection agency. Once an account is placed with an outside collection agency, we ask that patients work directly with the agency to resolve the balance. We hope this lessens confusion and frustration by eliminating unnecessary phone calls.
