PATIENT/DOCTOR DEBT RESPONSIBILITY

(FLORIDA)

I work for at a medical facility & i have noticed that there are outstanding debts from 2003 onwards -- isn't there a time limit (statute of limitations) on how long we can keep this debt on file? On most of the outstanding balances, patients have continued to use our facilities without having paid on old debt -- thereby, patients naturally state that we have continued to see them & that now we are demanding our due balances. As far as i can see, if the firm has been sending out invoices but there is no way of proving this by means of certified/registered/hand delivered receipt, can i still try to collect ?
