I work for an Optometrist in California, USA and am helping to send out invoices for patients with past due balances. I have noticed that there are several patients with balances dating back to a year or two ago and they were never mailed an invoice or contacted by mail. Is there some law that prevents mailing out an invoice now? I had heard from a billing friend that a bill or invoice cannot be mailed out more than 12 months after the balance was posted on the patients account. I am concerned that by mailing out a bill after this much time has past, and without trying to call or collect from patient before this, may result in loss of business or worse...lawsuit. Any info on timely invoicing in California would be greatly appreciated. Thank you
